Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a device for fixing and warming ECMO lower limb puncture catheter insertion lines. Background Technology

[0002] ECMO (Extracorporeal Membrane Oxygenation) is a life support technology that involves drawing blood from the body, oxygenating it using an artificial oxygenator (also known as a "membrane lung"), and then returning it to the body. It is a type of extracorporeal life support in a broad sense. ECMO equipment, also known as an artificial heart-lung machine, mainly consists of an artificial oxygenator, a drive pump, artificial tubing, and internal vascular cannulas. It can completely or partially replace the heart's pumping function and the lungs' gas exchange function to maintain the oxygen supply and relatively stable hemodynamics of the patient's entire body, ensuring the circulatory perfusion of vital organs and buying time for organ function recovery or further treatment.

[0003] After a puncture, reduced blood flow to the lower limbs can lead to a decrease in foot temperature. Existing medical devices cannot provide adequate warmth for the patient's lower limbs. Therefore, those skilled in the art have developed a device for fixing and warming ECMO lower limb catheter insertion lines to address the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a device for fixing and warming ECMO lower limb puncture catheter insertion lines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for fixing and warming ECMO lower limb puncture catheters, comprising a rigid shell supporting the patient's leg, a warming sleeve on the rigid shell that is fitted onto the patient's lower limb, a window on the warming sleeve for medical personnel to bandage or fix the catheter, and a protective component for closing the window is also installed on the warming sleeve.

[0006] Preferably, the protective component includes a protective strip sewn onto the insulation sleeve, the protective strip being used to cover the window on the insulation sleeve, the protective strip having a hook and loop fastener sewn onto it, and the bottom of the cardboard shell having a hook and loop fastener corresponding to the hook and loop fastener.

[0007] Preferably, the inner side of the rigid shell is equipped with a lifting block for supporting the patient's heel.

[0008] Preferably, the hard shell comprises a hard layer and a soft layer.

[0009] Preferably, the rigid layer is made of rigid polyethylene material, and the soft layer is made of pure cotton material.

[0010] Preferably, a heating element is sandwiched between the hard layer and the soft layer.

[0011] Preferably, the heating assembly includes an electric heating blanket installed between a rigid layer and a soft layer, the electric heating blanket being connected to a plug-in terminal via a cable, and the cable being provided with a control button.

[0012] Preferably, two sets of binding strips are adhered to the outer side of the rigid shell, with the two sets of binding strips located at the top and bottom of the protective strip, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the insulating sleeve and the hard shell are worn from the patient's feet to the groin. The hard shell can provide certain support and positioning for the patient's legs, while the insulating sleeve can provide good warmth for the patient's lower limbs. The insulating sleeve is provided with a window for medical staff to perform operations such as arterial puncture, dressing change, and bandaging, which can facilitate the patient's treatment. Furthermore, a protective component that is easy to open and close is provided to seal the window, which can facilitate the actual operation of medical staff and ensure the actual warmth of the insulating device. In addition, a heating component is clamped in the device, which can improve the actual warmth of the device.

[0015] 2. In this utility model, by setting up a lifting block, the patient's legs can be lifted to improve the patient's comfort after surgery. By setting up two sets of binding strips, the two sets of binding strips are used to tighten the insulation sleeve, which makes it easy to fix the insulation device firmly and improves the actual insulation effect. It also makes it easier for the patient to move the insulation device together. Moreover, both the hard shell and the lifting block are made of hard and soft layers. The components provide a rigid support effect while also improving the patient's comfort. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 In this embodiment of the present invention, a device for fixing and warming ECMO lower limb puncture catheters includes a rigid shell supporting the patient's leg, a warming sleeve 2 that is fitted onto the patient's lower limb on the rigid shell, a window 3 on the warming sleeve 2 for medical staff to bandage or fix the catheter, and a protective component for closing the window 3 is also installed on the warming sleeve 2.

[0020] The overall length of the device extends from the foot to the thigh. The insulating sleeve 2 and the hard shell are worn over the patient's lower limbs. The hard shell provides support and warmth for the patient's legs. A window 3 is opened between the knee and the thigh for arterial puncture, dressing changes, bandaging, and other operations at this location. A protective component is provided to close the window 3, which can improve the actual heat preservation effect of the device.

[0021] Specifically, the protective components include a protective strip 4 sewn onto the insulation sleeve 2, which is used to cover the window 3 on the insulation sleeve 2. The protective strip 4 has a hook and loop fastener 5 sewn onto it, and a hook and loop fastener 6 corresponding to the hook and loop fastener 5 is glued to the bottom of the rigid shell. The protective strip 4 is wrapped around the patient's leg, and the hook and loop fastener 5 is glued to the hook and loop fastener 6, which can easily seal and close the window 3. The tightly wrapped protective strip 4 can improve the windproof effect of the insulation device.

[0022] Furthermore, the inner side of the rigid shell is equipped with a lifting block 7 to support the patient's heel, which can help elevate the patient's leg and improve the patient's comfort after surgery. The rigid shell includes a rigid layer 8 and a soft layer 9. Accordingly, the rigid layer 8 is made of rigid polyethylene material, and the soft layer 9 is made of pure cotton material. The rigid layer 8 can provide a fixed support effect, while the soft layer 9 at the top can improve the patient's comfort when using the heat preservation device.

[0023] A heating component is sandwiched between the hard layer 8 and the soft layer 9. The heating component includes an electric blanket 1 installed between the hard layer 8 and the soft layer 9. The electric blanket 1 is connected to a plug-in terminal 12 via a cable 11. A control button 13 is provided on the cable 11. The electric blanket 1 has the same structural principle as the electric blankets 1 commonly used in the prior art that are laid on the bed. When the patient uses it, the heating component heats up the warming device, which helps to improve the patient's comfort.

[0024] Two sets of binding strips 10 are glued to the outside of the hard shell. The two sets of binding strips 10 are located at the top and bottom of the protective strip 4, respectively. The two sets of binding strips 10 are used to tighten the insulation sleeve 2, so as to make the insulation device securely fixed.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
