Description

Radial artery puncture fixing hand rest

Technical Field

The utility model relates to the field of medical appliances, in particular to a radial artery puncture fixing hand rest.

Background

The arterial puncture catheter is a conventional invasive operation in anesthesia department, is a technology which is mastered by each anesthesia department doctor, and is mainly used for monitoring the invasive arterial pressure in perioperative period. The radial artery is superficial, and the collateral circulation is rich, so that the arterial puncture catheter is generally preferred. The stretching position after the wrist is rotated can lead the radial artery to be exposed best, when the radial artery is punctured clinically, the arm is stretched outwards and placed on the hand rest plate, 500ml of physiological saline or rolled small square towel is padded under the wrist, and four fingers are wound by using the adhesive tape to reach the stretching position of the wrist, so that the optimal hand position for touching the radial artery pulsation is achieved, and the method is prolonged for a long time, is complicated and troublesome clinically; and the skin of the puncture part cannot be tightened, the optimal puncture point is not easy to find, repeated puncture or puncture failure is easy to cause, and the success rate of disposable puncture is low. Some of the rubberized fabrics are excessively wound, so that certain harm is caused to patients, and especially some people allergic to the rubberized fabrics; when the tearing adhesive tape is over-forced after the puncture is finished, the risk of tearing bleeding is also caused for patients with poor skin conditions.

Disclosure of Invention

Aiming at the problems, the utility model also aims at assisting in operation and simplifying the process, and provides the radial artery puncture fixing hand rest, so as to overcome the defects that the existing operation is complex, the skin of a puncture part cannot be stretched, the optimal puncture point cannot be easily found, and part of patients are injured by using adhesive tapes.

The specific scheme of the utility model is as follows: a radial artery puncture fixing hand rest comprises a plastic heightening platform, a wrist rest groove and a finger stall; the plastic heightening platform is a convex platform, a wrist placing groove is formed in the plastic heightening platform, a forearm slope is arranged at the near-center end of the plastic heightening platform, and the forearm slope is a short slope and can be attached to the forearm; the distal end of the plastic heightening platform is provided with a back slope, and the back slope is a long slope and can be attached to the back of the hand to enable the wrist to naturally extend; the finger stall is provided with four finger holes, and the finger can be fixed four fingers through the finger hole.

Preferably, the plastic heightening platform is made of silica gel material and can be adjusted in height.

Preferably, the wrist rest groove is groove-shaped to maximize comfort and fit.

The utility model has the following advantages: the radial artery puncture fixing hand frame provided by the utility model simplifies the steps of radial artery puncture preparation and improves the puncture efficiency; the shape accords with the physiological structure of the human body, the comfort level of the patient is met to the greatest extent, and the design of the adjustable height ensures that each operation step is more humanized.

Detailed Description

In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

As shown in fig. 1 and 2, the radial artery puncture fixing hand rest provided by the utility model comprises a plastic heightening platform 2 and a fingerstall 1; the plastic heightening platform 2 is a convex platform, a wrist placing groove 3 is arranged on the plastic heightening platform 2, the near center end of the plastic heightening platform 2 is provided with a forearm slope 5, and the forearm slope 5 is a short slope and can be attached to the forearm; the distal end of the plastic heightening platform 2 is provided with a dorsum slope 4, and the dorsum slope 4 is a long slope and can be attached to the dorsum to enable the wrist to naturally extend; the fingerstall 1 is provided with four finger holes through which fingers can pass to fix the four fingers.

The plastic heightening platform 2 is made of silica gel material and can be adjusted in height.

The wrist rest groove 3 is groove-shaped and just clamps the wrist to achieve maximum comfort and fit.

When the device is used, the hands of a patient are stretched outwards on the hand placing plate, the wrists are stretched outwards naturally, the radial artery puncture fixing hand rest is placed on the wrists, the height of the plastic heightening platform 2 is adjusted according to the stretching condition of the patient, the device is fixed according to the separation of fingers (similar to gloves), and the device is fixed at the most comfortable position of the patient, so that the most obvious position of touching the radial artery pulsation is achieved, and the harm of an adhesive tape to the fingers is avoided. The fixed hand rack is small in storage occupation space, portable to use, capable of simplifying preparation steps before puncture and improving puncture efficiency.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
