Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an inflatable radial artery puncture position pad. Background Art

[0002] Critically ill patients in operating rooms often require invasive arterial blood pressure monitoring. In clinical practice, radial artery puncture and catheterization are the first choice for measuring arterial blood pressure. In order to facilitate the insertion of the puncture needle and improve the success rate of puncture and catheterization, the patient's wrist position needs to be raised to achieve an ideal position. In clinical practice, gauze rolls or saline bottles are often used to temporarily raise the patient's wrist for adjustment. However, these methods have limited adjustment range and poor practicality, and lack fixation of the patient's wrist. The patient's wrist is easy to fall off, causing accidents and blood leakage, increasing the risk of cross infection. Therefore, an adjustable device for raising the patient's wrist and fixing the patient's hand position is needed. Utility Model Content

[0003] The utility model aims to provide an inflatable radial artery puncture position pad, which is used for padding the patient's wrist to a suitable position during radial artery puncture and fixing the patient's wrist.

[0004] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0005] The utility model provides an inflatable radial artery puncture position pad, comprising a base, an inflatable pad, a forearm fixing belt and a finger fixing belt are arranged on the upper surface of the base, the forearm fixing belt is arranged at the rear of the inflatable pad, the finger fixing belt is arranged at the front of the inflatable pad, one side of the inflatable pad is connected to a pressing airbag through an air tube, the other side of the inflatable pad is provided with a manual exhaust valve, and the lower surface of the base is provided with a bottom fixing belt;

[0006] The base can be fixed on the radial artery puncture hand stand by a bottom fixing belt, the patient's wrist is placed on the surface of the inflatable cushion, the forearm fixing belt is used to fix the patient's forearm, and the finger fixing belt is used to fix the patient's fingers;

[0007] Pressing the pressing airbag can inflate the inside of the inflatable cushion so that the inflatable cushion swells and lifts the patient's wrist, and pressing the bottom fixing belt can quickly release the gas inside the inflatable cushion.

[0008] As a preferred solution of the utility model, side pockets which are integrated with the base are provided on both sides of the base, and the side pockets can be used to fill medical instruments required for radial artery puncture.

[0009] As a preferred solution of the present invention, the base is made entirely of anti-slip material, and anti-slip grooves are provided on the bottom.

[0010] As a preferred solution of the present invention, the bottom fixing strap, the forearm fixing strap and the finger fixing strap are all elastic straps.

[0011] As a preferred solution of the utility model, a pressure valve is provided on the side of the inflation end of the press airbag. When the internal air pressure of the inflatable cushion and the pipe connected thereto is greater than the threshold of the pressure valve, excess gas will overflow from the pressure valve.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides an inflatable cushion with adjustable size at the bottom of the patient's wrist, thereby adjusting the height of the patient's wrist. The adjustment range is relatively flexible and can be suitable for different patients. The success rate of radial artery puncture and catheterization is increased by raising the patient's wrist to a suitable height. In addition, since the inflatable cushion is an inflatable cushion, it has good resilience and surface flexibility, which can greatly improve the comfort of the patient's wrist being placed on it. On the other hand, the device fixes itself through the bottom fixing belt, and fixes the patient's wrist through the forearm fixing belt and the finger fixing belt in cooperation with the expansion support of the inflatable cushion, so that the patient's hand is more completely limited during radial artery puncture, and the patient's wrist position is more stable during the puncture process.

Obviously, the drawings in the following description are only exemplary, and for ordinary technicians in this field, other implementation drawings can be derived from the provided drawings without creative work.

[0015] Figure 1 This is a schematic diagram of the appearance of the utility model;

[0016] The numbers in the figure represent the following:

[0017] 1-base, 2-inflatable cushion, 3-pressing airbag, 4-bottom fixing strap, 5-forearm fixing strap, 6-finger fixing strap, 7-manual exhaust valve, 8-side pocket, 9-pressure valve. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, the utility model provides an inflatable radial artery puncture position pad, comprising a base 1, an inflatable pad 2, a forearm fixing belt 5 and a finger fixing belt 6 are arranged on the upper surface of the base 1, the forearm fixing belt 5 is arranged at the rear of the inflatable pad 2, the finger fixing belt 6 is arranged at the front of the inflatable pad 2, one side of the inflatable pad 2 is connected to the pressing airbag 3 through an air tube, the other side of the inflatable pad 2 is provided with a manual exhaust valve 7, and the lower surface of the base 1 is provided with a bottom fixing belt 4;

[0020] The base 1 can be fixed on the radial artery puncture hand stand through the bottom fixing belt 4, the patient's wrist is placed on the surface of the inflatable cushion 2, the forearm fixing belt 5 is used to fix the patient's forearm, and the finger fixing belt 6 is used to fix the patient's fingers;

[0021] Pressing the airbag 3 can inflate the air cushion 2 so that the air cushion 2 swells and lifts the patient's wrist. Pressing the bottom fixing belt 4 can quickly release the gas inside the air cushion 2.

[0022] The pressing airbag 3 in the above-mentioned device is an ordinary resilient pressing airbag, which is generally elliptical, and has unidirectional air valves at both ends. The air valve at the end connected to the gas pipeline is directed toward the trachea, and the air valve at the end connected to the outside is directed toward the inside of the pressing airbag 3, so that when the pressing airbag 3 is pressed, the internal gas is pressurized and injected into the inflatable cushion 2 from the gas pipeline. After the pressing airbag 3 is released, the pressing airbag 3 rebounds to generate negative pressure inside, and the external air is refilled into the pressing airbag 3 under negative pressure. In this way, the pressing airbag 3 can be repeatedly pressed and released to complete the inflation of the inflatable cushion 2. In actual use, medical staff can control the inflation expansion amplitude of the inflatable cushion 2 according to actual conditions, so that the wrists of different patients can be adjusted to a suitable height to facilitate radial artery puncture by themselves.

[0023] On the other hand, the above-mentioned device can be tied to the long radial artery puncture hand frame through the bottom fixing belt 4 at the bottom of the base 1 to complete the fixation of the entire device. The patient's hand is located on the inflatable cushion 2 and below the forearm fixing belt 5 and the finger fixing belt 6. When the inflatable cushion 2 is inflated and lifts the patient's wrist, it will naturally generate an opposite squeezing force to the forearm fixing belt 5 and the finger fixing belt 6. The patient's wrist and forearm are located above the device at the lower limit of the squeezing force. After the radial artery puncture and catheterization are successful, the gas inside the inflatable cushion 2 can be quickly released through the manual exhaust valve 7, so that the volume of the inflatable cushion 2 is reduced, so that the squeezing force between the inflatable cushion 2 and the forearm fixing belt 5 and the finger fixing belt 6 is reduced, which makes it convenient for the patient's arm to be pulled out from the top of the inflatable cushion 2 from the end of the forearm fixing belt 5.

[0024] To sum up, the usage process of this device is as follows:

[0025] 1. The medical staff places the base 1 on the radial artery puncture holder, and fixes the radial artery holder by tying the holder with the bottom fixing belt 4 at the bottom of the base 1;

[0026] Second, the patient extends his hand to the surface of the base 1, and passes it under the forearm fixing belt 5, above the inflatable cushion 2, and under the finger fixing belt 6 in sequence, so that his forearm is located under the forearm fixing belt 5, the wrist is carried on the surface of the inflatable cushion 2, and is slightly lifted by the inflatable cushion 2, and the fingers are located under the finger fixing belt 6;

[0027] 3. The medical staff repeatedly presses the airbag 3 to inflate the air cushion 2 and props up the patient's wrist to a suitable position before puncturing and cannulating the radial artery;

[0028] 4. After the radial artery puncture and catheterization are successful, the manual exhaust valve 7 is manually opened to release the gas in the inflatable cushion 2, so that the inflatable cushion 2 is deflated, and then the patient can withdraw his arm from under the forearm fixing belt 5 section.

[0029] In addition, considering that radial artery puncture requires the use of sterile cotton swabs, puncture needles, adhesive tape and other tools, in order to enable these items to be readily available when the device is used, further, side pockets 8 that are integrated with the base 1 are provided on both sides of the base 1, and the side pockets 8 can be used to fill the medical instruments required for radial artery puncture.

[0030] Considering that if there is no radial artery puncture stent, the base 1 can be laid flat on a hard plane and fixed. The base 1 can be further set to be made of a non-slip material as a whole, such as rubber, silicone and other materials with a large surface friction coefficient, and the bottom is provided with anti-slip grooves. This can greatly increase the anti-lateral displacement effect of the base 1 on the hard plane, so that the device as a whole can be stably fixed in a specific position.

[0031] In addition, in order to facilitate the quick use of the device, the bottom fixing strap 4, the forearm fixing strap 5 and the finger fixing strap 6 can be set to be elastic straps. The elastic straps can provide extrusion limiting force by shrinking. It is only necessary to insert the limiting object or the limited object into the shrinkage range of the elastic strap.

[0032] At the same time, in order to avoid the inflatable cushion 2 from bursting due to excessive inflation, a pressure valve 9 can be provided on the side of the inflation end of the pressing airbag 3. When the internal air pressure of the inflatable cushion 2 and the pipe connected to it is greater than the threshold of the pressure valve 9, excess gas will overflow from the pressure valve 9.

[0033] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
