Blood collection is usually performed on the arm support. The patient places his arm on the arm support, which supports and stabilizes the patient's arm to facilitate the blood collection operation by medical staff. The function is relatively single and cannot provide more support and assistance to medical staff. Especially during blood collection, the patient needs to wear clothes with loose cuffs to facilitate blood collection. However, the patient sometimes does not dress as required and wears clothes with cuffs that are too small or too tight. It is difficult to roll up the sleeves during blood collection, or subcutaneous hematoma is generated due to hemostasis disorder caused by tight sleeves after blood collection. To avoid subcutaneous hematoma, blood collection needs to be performed after undressing. This is inconvenient for some elderly people or people with mobility difficulties and affects the medical experience. For special groups who need care such as hospitalized patients or blood collection for physical examinations, medical staff need to confirm the patient's hemostasis before blood collection.
[0003] 1. The traditional arm rest is only composed of a base with an arc-shaped groove and a leather sponge on its surface. However, in this way, during the blood collection process, the blood collector may accidentally move his arm, which may cause danger during blood collection.
[0004] 2. A general arm rest is provided with a leather strap just above the base of the arc-shaped groove to fix the arm of the blood collector. However, the reliability of this method is not great and it is not possible to fix the arm of the blood collector safely and reliably. Utility Model Content

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides a technical solution: an arm rest 2 is arranged just above a frame 1 , a non-slip foot pad 3 is arranged at the bottom of the frame 1 , and a sliding device 4 is arranged inside the frame 1 .
[0021] The arm support 2 is composed of an arm support No. 1 201 and an arm support No. 2 202 , and the sliding device 4 is composed of a slider 401 , a spring 402 , a pull rod 403 and a pulley 404 .
[0022] The arm rest 201 is located on the left side just above the frame 1, and the arm rest 201 is fixed on the top of the frame 1. The arm rest 201 consists of two arm rests, one large and one small. The arm rest 202 is located on the right side just above the frame 1, and the arm rest 202 and the arm rest 201 are in a mirror image relationship.
[0023] The anti-skid foot pads 3 are located right below the frame 1, and there are 4 groups of anti-skid foot pads 3 located right below the frame 1 and around it. The foot pads are cheap and can meet the quality requirements for use.
[0024] There are two groups of sliders 401 located inside the frame 1, and the sliders 401 are located directly below the No. 2 arm rest 202. The spring 402 is located on the left side of the slider 401, and one end of the spring 402 is fixed to one side of the inner wall of the frame 1, and the other end of the spring 402 is fixed to the left side of the slider 401. The pull rod 403 is located on the right side of the slider 401, and one end of the pull rod 403 is fixed to the pull rod 403, and the other end of the pull rod 403 is located on the outside of the frame 1. The pulley 404 is located directly above the slider 401 and slides in the groove at the bottom end of the frame 1. The biggest advantage of this device is that it can fix the arm of the blood collector very well, and the number of internal parts is small, and it is extremely convenient to operate.
[0025] Working principle: When medical staff need to draw blood, first of all, they need to place the frame of the arm rest flat on the table to ensure that the arm rest will not tilt during the blood collection process. Medical staff need to manually pull the pull rod 403 outward. At this time, because the spring 402 is fixed to the slider 401, and the slider 401 is fixed to the No. 2 arm rest 202 directly above it, the pull rod 403 will drive the No. 2 arm rest 202 to slide to the right when it is pulled outward. At this time, the No. 2 arm rest 202 will generate a resistance caused by the spring 402. Therefore, when the blood collector puts his arm into the left side of the No. 1 arm rest 201, the medical staff slowly releases the pull rod 403. 403, the pulley 404 at the bottom of the slider 401 will move back with the slider 401. At this time, the inner side of the No. 2 arm support 202 will contact the arm of the blood collector and clamp the arm of the blood collector. Since the upper arm and forearm of the human arm are of different sizes, one group of the two arm supports of the No. 2 arm support 202 will clamp the upper arm of the blood collector, and the other group will clamp the forearm of the blood collector, so as to prevent the arm from shaking during the blood collection process. When the blood collection is completed, the medical staff can pull the pull rod 403 outward. There are two sets of leaves on the left side of the frame 1, and the frame 1 can be opened regularly to maintain its interior. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.
