A support device for assisting a patient is used to assist the movement of a patient at the patient support device. In the prior art, a caregiver would operate a patient lift or motor by guiding the lift to raise or lower the patient at the patient support. Such manipulations often require the precise manipulation of heavy forceps and motors by a paramedic to help the patient move around the patient support.        The support means may incorporate a constant force spring design, the support structure comprising a base and an upper portion extending upwardly from the base. The constant force spring assembly may include a carrier slidably coupled to the base secured to a first end of the carrier. The base may include channels that guide sliding movement of the carrier relative to the base of the support structure. The constant force spring assembly may also include a spool and a motor configured to drive the spool....
Types of Springs in Medical Devices
Types of Springs in Medical Devices
Springs are integral components in the manufacture of many medical devices. Whether it’s for a surgical stapler or a medical monitor, the types of springs in medical devices are defined by a specific action or movement required for the application. Though relatively simple in its design, springs store the mechanical energy necessary for a wide range of medical devices, machinery, and equipment to function properly. Any type of surgical instrument, medical equipment or device that has a mechanism undoubtedly has a spring component. Spring material must be medical grade, and the design and function of any device must adhere to stringent regulatory requirements and guidelines as defined by the FDA. Booms, table and bed lifts, fluid control devices, wheelchairs, medical testing and monitoring equipment either fixed or mobile, MRI and X-ray machinery, dental x-ray with articulated arms, medical equipment drawer closing mechanisms, anesthetic infusion devices, sterilization valves, various implants, and shunt valves are all examples of medical devices that require...

Constant force spring is used in removing an implanted object using laser cut hypotubes
Removal or extraction of the lead may be difficult. As mentioned above, the body's natural healing process forms scar tissue over and along the lead, and possibly at its tip, thereby encasing at least a portion of the lead and fastening it even more securely in the patient's body. In addition, the lead and/or tissue may become attached to the vasculature wall. Both results may, therefore, increase the difficulty of removing the leads from the patient's vasculature. A device for removing an implanted object from a body vessel, may comprise a sheath assembly comprising an outer sheath assembly and an inner sheath assembly, and a pin, the outer sheath assembly comprising an outer sheath and an outer band, the outer band coupled to the pin, the inner sheath assembly comprising an inner sheath and a tip, wherein the tip has a cutting surface, the inner sheath comprising a proximal end and a distal end, wherein the distal end of the...

Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs.          During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design, it may be beneficial to use a fixed mandrel/free box or free box/fixed mandrel arrangement.        These springs are typically used to retract the cord or cable of the spool. You might see it in lawn mowers, retractable lanyards, or dog leashes. This is also the type of spring used to drive many mechanical clocks and timers, which is why they are sometimes called "clock springs". The load provided by the spring increases with the cross-sectional area of ​​the material. The number of turns the spring can provide depends on the space available between the mandrel and the...

All curtain cords, whether installed on the side, caught in curtains, or placed on the back, can be dangerous to children. It is best to replace all corded curtains with cordless curtains in houses where children live or visit, especially in children's bedrooms and play areas. Cordless roller blinds with either a spring system or an electric system can improve the safety of the home.        Cordless roller blinds with spring system are similar to movie curtains. They use the elasticity of the springs. Under the action of the spring components, the roller blinds can be balanced at any position and can be stopped at any time.        At present, most of the spring components on the market are wire spring cordless curtain systems, which have a relatively short service life and a high degree of force attenuation. When pulling down, the curtain stops at each clip, and when rising, pulling down makes the curtain bounce back to the top, which can only make the curtain go up and down within the range, and cannot make the curtain stop freely at any position. The structure is more complex, and it needs to cooperate with damping and limit devices. When the spring force value is attenuated, the feel of the curtain will change.        The core component of Qianye's precision-designed spring cordless curtain system is a spring with a negative gradient. Compared with the traditional wire spring cordless curtain system, the advantages are as follows:        1. Lifespan: Compared with traditional wire spring...

 When powered by a damped constant force spring mounted on the spool, there are several key principles that influence the design of linear motion applications. These principles support robust and consistent performance of products in a variety of applications, including automotive and aircraft interiors, industrial machine components, and many other user interface applications. The example components shown above will be cited as examples of the various design principles detailed below. This example assembly has a sliding drawer (shown in red) powered by a constant force spring mounted on a spool (spool in green; constant force spring shown in yellow) running within a mounting base (shown in grey), such as a central Console a car. A ratchet or door latch mechanism (not shown) can be implemented to allow the tray to be locked in place with a single press by the user. This example is a typical set of applications used in the automotive industry.        1. Preload spring        When a constant force spring is in its free state, it does not exert any force. As the spring stretches, the spring force rapidly increases from zero to nominal load. However, to avoid including this "accelerated" part of the work envelope, the design can use preloading. An example of preloading is shown in the figure below. Note that although the mechanism is retracted, the depicted spring is extended.        To include preload in the design, ensure that the spring extends a distance equal to the outer diameter of the coil during assembly in order to engage...

The reason why the world we live in is so orderly is that there are precise links between large and small objects. So many things in life are crucial. Whether they are large or small, they are indispensable to our life, but some small parts in life are unknown, but there are tens of thousands of them. The spring I know is also one of them. It always exists in a position that people can't see and does their own thing silently. Moreover, he exists everywhere in life, even if we don't know it. Today, I will explain the functions of these small springs. Spring is a kind of mechanical part that uses elasticity to work. Generally made of spring steel. Although the spring is small, as a general basic part, it has large quantity, wide range and complex varieties. It is used to control the movement of mechanical parts, mitigate impact or vibration, store energy, measure the size of force, etc. it is widely used in machines and instruments. The application field involves almost all fields of the national economy. Spring plays a big or small role in all articles in our life. It also has different shapes and structures because of different force values. However, according to the force value, people still divide it into three categories: constant force spring, power spring and variable force spring. Its working principle is to use one of its characteristics. It deforms it by applying force and will also try to return to its original state. Let me show you how springs...

If the plush toys in the car are the favorite of female car owners, it is believed that the favorite of male car owners is the vehicle ashtray. Car ashtrays are indispensable car supplies for smokers. Although the vehicle ashtray is specially designed for smokers' car owners, it can also be used to place sundries for non-smoking car owners, which is very practical. When it comes to car ashtrays, I have to mention the problem of smoking in the car. In fact, smoking in the car is more dangerous than smoking outside. After all, the space in the car is limited, and the air circulation range is small. In this case, smoking will certainly cause air pollution in the car.      However, at present, the utilization rate of ashtrays on many models is not very high. Most smokers' car owners pop ashtrays out of the window directly. The function of on-board pop-up ashtrays can greatly improve this situation. Now many cars have ashtrays designed under the central control and in the rear row to facilitate smokers in the car. In addition, some luxury cars also have ashtrays designed under the door handle. Most of the vehicle ashtray structures are in the shape of cylindrical cups, and the sealing performance is also relatively good. Generally, cigarette butts are thrown in. Basically, there is no smoke smell floating out, and the sealing is more humanized. Pop up ashtray riders may worry about whether the car will be a little bumpy, and the ashtray will pop up automatically. The ashtray will fly everywhere,...

       Springs are an important part of many different industries, including the aerospace industry. They form the backbone of many components and allow planes, drones, satellites, solar panels, aircraft controls, valves, throttles, and more to function their way. Without the spring, the industry would not be the same. Strict military and aviation guidelines mean that all components of the aircraft, including the springs, must be of the highest quality and precision; they support a wide range of applications and reduce part weight while maintaining the highest performance standards. This makes springs vital to the aerospace industry. Without springs, we wouldn't be able to have the essentials of aerospace. For example, retractable tray tables, trunk doors, handrails, stairs and cup holders require springs to function. They help open and close many components that wouldn't exist without them—and, more importantly, springs are some of the main elements of aircraft landing systems. They are also present in satellite dishes and probes that allow navigation and are critical for ground service teams that need to refuel aircraft. You can find springs basically anywhere in the industry, and their absence means that airplanes as we know them don't exist. Part of the reason springs are so important in aerospace is that they are very resistant to compression. Aircraft require robust and durable components that do not require frequent maintenance, upgrades or replacements, but are at the same time extremely precise. Many applications in aerospace require the ability to withstand harsh environments on a regular basis, from aircraft that fly around the world every...
