Description

A kind of hand rest for arterial puncture

technical field

The utility model belongs to the technical field of medical devices, and relates to a hand rest for arterial puncture.

Background technique

In clinical medicine, it is often necessary to perform arterial puncture on patients to draw arterial blood for laboratory tests. At present, arterial puncture is usually performed on the radial artery. During radial artery puncture, the patient needs to be in a supine position, the puncturing arm needs to be abducted, and a wrist pad needs to be placed under the patient's wrist during puncture, so as to keep the patient's radial artery in the position as far as possible. Stretched state to improve the success rate of puncture.

At present, arterial puncture is mainly performed on an operating table or a hospital bed. Since the operating table is a professional device, a special hand-holding board structure is usually configured, such as a double-joint hand-holding board and operating bed disclosed in Chinese Patent Application No. 201320485318.4. The operating bed is specially set with rails, and a hand board is set on the rails to support the patient's arms. However, on a common hospital bed, such a pallet structure is usually not specially equipped, and only a portable pallet is used for arterial puncture. For example, a kind of arterial puncture hand support plate disclosed in Chinese patent application application number: 201720477664.6, the main body is a plane hand support board, the position on the board surface of the plane hand support board in contact with the patient's wrist is provided with a bulge, and the position in contact with the patient's finger is provided with Buckle. Due to the limited space on the hospital bed, if the hand support board is directly placed on the hospital bed, the patient's arm will not be fully extended, which will lead to inconvenient puncture operation and affect the success rate of arterial puncture. Therefore, medical staff usually support the hand support board through a stool , placed on one side of the hospital bed for use, which leads to the need for a stool specially equipped with support during use, which is cumbersome to use.

SUMMARY OF THE INVENTION

The purpose of this utility model is to solve the above problems in the existing technology, and propose a hand rest for arterial puncture.

The purpose of the utility model can be achieved by the following technical solutions: a hand rest for arterial puncture, comprising a hand rest plate arranged laterally and used to support the arm, the hand rest plate is provided with a wrist pad for supporting the wrist, It is characterized in that, one end of the hand shelf has two vertically arranged fixing plates, and the two fixing plates are arranged at intervals along the length direction of the hand shelf and form installation grooves.

The hand shelf is in the shape of a long strip, a wrist pad is arranged on the hand shelf, and one end of the hand shelf is provided with a fixing structure formed by two fixing plates. When in use, the hand rest for arterial puncture cooperates with the guard rail or the bed beam on the side of the hospital bed through the installation groove between the two fixing plates, so that the guard rail or the bed beam is embedded in the installation groove to realize the clamping and fixing, so that the hand shelf is It is fixed horizontally relative to the bed and extends toward the outside of the bed for placement of the patient's arm during arterial puncture.

In the above-mentioned hand rest for arterial puncture, two fixing plates or one of the fixing plates are provided with a plurality of installation holes spaced along the length direction of the fixing plates, and ball screws are arranged in the installation holes. One end of the ball screw with the steel ball protrudes out of the installation groove. In this way, after the guardrail or the beam is embedded in the installation groove, the steel ball at the front end of the ball screw can closely abut against the guardrail or the beam, which further improves the fixing effect of the hand rest.

In the above-mentioned hand rest for arterial puncture, the upper surface of the hand rest is provided with a flexible elastic layer. The flexible elastic layer is made of artificial leather wrapped sponge material to improve the comfort of the patient's arm resting on the hand rest.

In the above-mentioned hand rest for arterial puncture, an annular first fixing band is fixedly connected to the wrist pad, and the first fixing band is sleeved on the hand rest and can move along the length direction of the hand rest. The wrist pad is movably connected with the hand rest through the fixing strap, so that the wrist pad can adjust the position according to the length of the patient's arm, so as to facilitate the arterial puncture operation and improve the comfort of the patient.

In the above-mentioned hand rest for arterial puncture, the hand rest is further provided with a plurality of hand straps spaced along the length direction of the hand rest, and the hand straps include a first strap, a second strap and an annular the second fixing belt, the second fixing belts are all sleeved on the hand shelf and can move along the length direction of the hand shelf; One end of the strap and the second strap are fixedly connected with the second fixing strap, and the other ends of the first strap and the second strap are respectively provided with Velcro which can be adhered to each other. The hand strap can fix the patient's arm on the arm rest, preventing the patient from shaking due to pain during the arterial puncture process, improving the accuracy of arterial puncture, and the position of the hand strap can be adjusted for better adaptation Arms of different patients.

In the above-mentioned hand rest for arterial puncture, there are three hand straps, the three hand straps are respectively located on both sides of the wrist pad, and there are two hand straps between the installation groove and the wrist pad. In this way, two of the hand straps are used to fix the arm, and the remaining one is used to fix the palm, and the fixation effect is better.

Compared with the prior art, the utility model has the following advantages:

1. The installation groove formed by the two fixing plates of the present invention is fixed with the guard rail or beam of the sickbed, which facilitates the disassembly and assembly of the present invention, is more convenient to use, and has better adaptability.

2. Both the wrist pad and the hand strap are movably connected to the hand rest plate, so that the position of the wrist pad and the hand strap can be adjusted according to the length of the patient's arm, and the support and fixation effect of the patient's arm are better.
