Problems solved by technology

[0002] In orthopedic surgery, when operating on the middle and distal limbs of the limbs, sometimes in order to clear the surgical field of view, reduce the patient's blood loss, improve the efficiency of the operation and shorten the operation time, it often requires the steps of expelling blood and hemostasis. However, currently The blood expelling belt is made of elastic rubber sheet, the length can be cut according to the needs, it can be fumigated or boiled and sterilized before use, and can be used repeatedly
[0003] However, the rubber material of the above-mentioned blood-expelling belt and the material of the supporting inflation valve are relatively hard, which is easy to strangle the skin during blood-expelling, and the use after repeated sterilization increases the working cost of medical staff. The risk of infection, in order to reduce the above problems, it is necessary to design a disposable and softer blood drive belt and a matching inflation valve, which can facilitate blood drive and hemostasis, save the working cost of medical staff and reduce secondary risk of infection

Embodiment 1

[0025] like figure 1 and 2 As shown, an air valve for an inflatable device includes a valve body 1. The valve body 1 is composed of an upper diaphragm 11 made of TPU material, a polymer gel 12 and a lower diaphragm 13 made of TPU material. The specific combination method In order to place the lower diaphragm 13, the polymer gel 12 and the upper diaphragm 11 in order from bottom to top, and then seal the upper diaphragm 11 and the lower diaphragm 13 by pressing or bonding, the sealed polymer The gel 12 is placed in the sealed cavity formed by the sealing of the upper diaphragm 11 and the lower diaphragm 13 . In order to facilitate the perforation of the air needle during use, a positioning point or a positioning hole is provided at the center of the upper diaphragm 11 .

[0026] In specific use, the above-mentioned air valve is sealed and connected to the main body to be inflated, and the inflatable air needle is inserted at the positioning point of the air valve until it pen...

Embodiment 2

[0029] like image 3 As shown, an air valve for an inflatable device is composed of a valve body 1 and an inflatable limit assembly 2, wherein the valve body 1 includes an upper diaphragm 11, a polymer gel 12 and a lower diaphragm 13. The specific combination The method is to place the lower diaphragm 13, the polymer gel 12 and the upper diaphragm 11 in sequence from bottom to top, and then seal the upper diaphragm 11 and the lower diaphragm 13 by pressing or bonding. The molecular gel 12 is placed in a sealed cavity formed by the sealing of the upper diaphragm 11 and the lower diaphragm 13 . The material of the upper film and the lower film can be thermoplastic polyurethane (ie TPU) film or polyvinyl chloride (ie PVC) film or polyethylene (ie PE) film or polyamide (ie PA) film or polypropylene (ie PP) film or other elastic films of similar properties or thermoplastic elastic films.

[0030] The inflatable limiting assembly 2 is fixed under the valve body 1, and includes a c...

Embodiment 3

[0033] like Figures 3 to 5 As shown, an air valve for an inflatable device is composed of a valve body 1 and an inflatable limit assembly 2, wherein the valve body 1 includes an upper diaphragm 11, a polymer gel 12 and a lower diaphragm 13. The specific combination The method is to place the lower diaphragm 13, the polymer gel 12 and the upper diaphragm 11 in sequence from bottom to top, and then seal the upper diaphragm 11 and the lower diaphragm 13 by pressing or bonding. The molecular gel 12 is placed in a sealed cavity formed by the sealing of the upper diaphragm 11 and the lower diaphragm 13 . The material of the upper film and the lower film can be thermoplastic polyurethane (ie TPU) film or polyvinyl chloride (ie PVC) film or polyethylene (ie PE) film or polyamide (ie PA) film or polypropylene (ie PP) film or other elastic films of similar properties or thermoplastic elastic films.

[0034] The inflatable limiting assembly 2 is fixed under the valve body 1, and inclu...

Abstract

The invention of the invention relates to the field of medical equipment, and provides an air valve for an inflatable device, comprising: a valve body, the valve body includes an upper diaphragm, a polymer gel and a lower diaphragm, the upper diaphragm is connected to the The lower diaphragm is sealed along the circumferential direction to form a closed cavity, and the polymer gel is placed in the closed cavity. The air valve for an inflatable device further includes an inflatable limiting component, and the inflation limiting component is fixed under the valve body and includes a circular base plate and an annular side wall fixed on the circular base plate. , there are only a few air outlets evenly opened on the annular side wall. The invention has the advantages that a new type of soft sealing air valve with simple structure and good sealing effect can be designed by using the existing soft medical materials, which can replace various inflatable valve bodies with complex structures.

Description

technical field [0001] The invention of the invention relates to the field of medical devices, in particular to an air valve used for inflatable devices of medical devices. Background technique [0002] In orthopaedic surgery, when performing surgery on the middle and distal limbs, sometimes in order to clear the surgical field of vision, reduce the blood loss of the patient, and at the same time improve the efficiency of the operation and shorten the operation time, the steps of expulsion and hemostasis are often required. However, the current use of The expelling belt is made of rubber sheet with good elasticity, and the length can be cut according to the needs. It can be fumigated or boiled and sterilized before use, and can be used repeatedly. [0003] However, the rubber material of the above-mentioned expelling belt and the material of the matching inflatable valve are relatively hard, and it is easy to strangle the skin during expelling blood, and the repeated use aft...
