Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology, specifically relating to a height-adjustable dual-purpose fistula pad. Background Technology

[0002] An arteriovenous fistula pad, also called an arteriovenous fistula pillow, is used to elevate the arm with the fistula after arteriovenous fistula surgery, promote blood return, prevent swelling of the limb on the side with the fistula, and can also be used for patients with edema at the fistula site.

[0003] Existing fistula pads have a fixed height, making it impossible to adjust their height according to the patient's body shape. Furthermore, the material is relatively rigid, resulting in poor comfort, and they cannot be folded for storage. Additionally, existing fistula pads have limited functionality and cannot meet the needs of users. Summary of the Invention

[0004] This invention addresses the shortcomings of existing arteriovenous fistula pads, such as the inability to adjust height and limited functionality, by providing a height-adjustable dual-purpose arteriovenous fistula pad. This pad uses a height-adjustable airbag, allowing for height adjustment as needed. The airbag material is soft and provides high comfort. It can also be used as a simple armrest with a shoulder strap.

[0005] The objective of this invention is achieved through the following technical solution: a height-adjustable dual-purpose fistula pad, comprising a supporting base plate, an adjustable airbag pad fixedly mounted on the upper end of the supporting base plate, the airbag pad being formed by at least two layers of airbags stacked longitudinally, adjacent airbags being fixedly connected, each layer of airbags being provided with an inflation / deflation valve, the upper end face of the airbag pad being inclined and having an arm placement groove on the upper end face of the airbag pad; an anti-slip pad fixedly mounted on the bottom of the supporting base plate, the anti-slip pad having a through groove, and a shoulder strap passing through the through groove.

[0006] Preferably, each airbag layer has a connecting ring on its side, and a connecting strap that mates with the connecting ring is fixedly connected to the support base plate. The outer end of the connecting strap is fixedly provided with Velcro, and the connecting strap can pass through the connecting ring and allow the Velcro to be attached to the connecting strap.

[0007] Preferably, the connecting ring is made of a flexible material and is fixedly disposed on the side of the airbag.

[0008] Preferably, the connecting ring is made of fabric.

[0009] Preferably, the airbags in the airbag cushion are arranged such that the uppermost airbag is an arm cushion airbag, the thickness of which gradually decreases from one end to the other, and the remaining airbags are height-adjustable airbags with uniform thickness.

[0010] Preferably, the arm placement slot is a waist-shaped structure that is narrow in the middle and wide at both ends.

[0011] Preferably, the side of the arm placement slot is curved.

[0012] Preferably, there are two anti-slip mats, and a storage bag for storing shoulder straps is also fixed at the bottom of the support base plate, with the storage bag located between the two anti-slip mats.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The fistula pad of this application is inflatable, and the air cushion is inflatable in three stages, and the inflation height can be selected according to the patient's needs to achieve height adjustment;

[0015] 2. The part of the fistula pad in this application that comes into contact with the patient's arm is the upper end of the airbag pad. The airbag material is relatively soft and provides a high level of comfort.

[0016] 3. Can be folded and stored when not in use;

[0017] 4. After arteriovenous fistula surgery, patients can use the matching shoulder strap as a simple arm support when getting out of bed. Attached Figure Description

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0024] Example 1

[0025] like Figures 1-4 As shown, a height-adjustable dual-purpose fistula pad includes a support base plate 1. A height-adjustable airbag pad 2 is fixedly installed on the upper end of the support base plate 1. The airbag pad 2 is composed of three layers of airbags stacked longitudinally, with adjacent airbags fixedly connected. Each layer of airbags is equipped with an inflation / deflation valve 3. Through the inflation / deflation valve 3, the airbags can be inflated or deflated to adjust the air intake of each layer of airbags.

[0026] The upper surface of the airbag cushion 2 is inclined and the upper surface of the airbag cushion 2 is provided with an arm placement groove 4. The arm placement groove 4 is a waist-shaped structure that is narrow in the middle and wide at both ends, and the side of the arm placement groove 4 is an arc surface.

[0027] The airbags in the airbag cushion 2 consist of several layers. The topmost airbag is the arm cushion airbag 5, which gradually thins from one end to the other, causing its upper end to be tilted. This tilts the upper surface of the airbag cushion 2, facilitating the elevation of the arm where the fistula is located. The arm placement groove 4 is located on the upper surface of the arm cushion airbag 5. The remaining airbags are height-adjustable airbags 6 with uniform thickness.

[0028] Two anti-slip pads 7 are fixedly installed at the bottom of the support base plate 1. Each anti-slip pad 7 has a through groove 8 through which a shoulder strap 9 passes. A storage bag 11 for storing the shoulder strap 9 is also fixedly installed at the bottom of the support base plate 1, located between the two anti-slip pads 7. When this invention is placed on a table or bed, the anti-slip pads 7 provide a non-slip function, preventing the fistula pad from sliding when the arm is placed on it. After fistula surgery, when the patient gets out of bed, the shoulder strap 9 can be threaded through the anti-slip pads 7, at which point the fistula pad can be used as a simple armrest. When the shoulder strap 9 is not needed, it can be stored in the storage bag 11.

[0029] Each airbag layer has a connecting ring 10 fixedly attached to its side. The connecting ring 10 is made of flexible fabric. A connecting strap 13 that mates with the connecting ring 10 is fixedly connected to the support base plate 1. A Velcro 11 is fixedly attached to the outer end of the connecting strap 13. The connecting strap 13 can pass through the connecting ring 10 and the Velcro 11 can be attached to the connecting strap 13. When adjusting the height of the fistula pad, the height adjustment airbag 6 may sometimes be in an uninflated and deflated state. In this case, the connecting strap 13 can be passed through the connecting ring 10 on the already inflated height adjustment airbag 6 or the connecting ring 10 on the arm pad airbag 5, and the connecting strap 13 can be tightened so that the Velcro 11 on the connecting strap 13 is attached to the connecting strap 13. This can prevent the uninflated airbag from deploying. When the fistula pad is folded and stored, the connecting strap 13 can also be passed through the connecting ring 10 on the arm pad airbag 5 for fixation to prevent the uninflated airbag from deploying.

[0030] In this application, the height adjustment of the fistula pad is actually the height adjustment of the airbag pad 2. The overall height of the fistula pad is adjusted by inflating part of the height adjustment airbag 6 or by adjusting the inflation volume. The operation is very simple and convenient.
