[0024] 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 of 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.

[0025] like Figures 1 to 4As shown, a convenient clinical blood sampling device for gastroenterology includes a base 1, a placement rack 2 for placing the patient's arm is provided on the base 1, and an adjustment mechanism 3 and a limiting mechanism 4. The adjustment mechanism 3 is arranged between the base 1 and the placement rack 2. The adjustment mechanism 3 is used to adjust the position of the placement rack 2 on the base 1. In actual use, medical staff can flexibly adjust the position of the placement rack 2 on the base 1 according to the patient's body shape, body proportions and arm length, so that the placement rack 2 can adapt to patients with different body shapes and arm lengths. At the same time, there is no need to use additional cushions or other supports, which simplifies the operation of medical staff. The limiting mechanism 4 is provided with two groups, and is respectively arranged at both ends of the placement rack 2. The limiting mechanism 4 is used to fix the patient's arm on the placement rack 2, so as to ensure that the patient's arm remains stable during the blood drawing process. Even if the patient subconsciously moves his arm due to pain or tension, the limiting mechanism 4 can effectively prevent the sudden withdrawal of the arm, thereby greatly reducing the risk of needle displacement, blood splashing or insufficient collection.

[0026] In some specific embodiments, in order to enable medical personnel to adjust the position of the placement rack 2 on the base 1 conveniently and quickly, the adjustment mechanism 3 includes a limit bracket 31 and a movable slide 32, the limit bracket 31 is fixedly arranged on the top of the base 1, the limit bracket 31 is provided with a vertical slide 33, the movable slide 32 is slidably arranged in the slide 33, the placement rack 2 is arranged on the top of the movable slide 32, and the slide 33 is provided with a limit fixture for fixing the movable slide 32. The movable slide 32 slides in the slide 33 of the limit bracket 31, so that medical personnel can adjust the height of the placement rack 2 conveniently and quickly; at the same time, the patient's arm can be comfortably placed on the placement rack 2 during blood drawing, thereby improving the patient's comfort.

[0027] In some specific embodiments, in order to improve the accuracy and stability of the position adjustment of the placement rack 2 above the base 1, the position-limiting fixture includes a vertical shaft 34, the vertical shaft 34 is rotatably arranged in the slide slot 33, the outer side of the vertical shaft 34 is provided with an external thread, the movable slide 32 is provided with a through hole, and the through hole is provided with an internal thread that matches the external thread on the outer side of the vertical shaft 34. Through the thread matching of the external thread of the vertical shaft 34 and the internal thread in the through hole of the movable slide 32, the medical staff can accurately adjust the position of the placement rack 2 above the base 1. This thread matching method not only provides stable support, but also ensures the accuracy and reliability of the position adjustment of the placement rack 2 above the base 1, and further reduces the risk of blood drawing caused by arm movement. At the same time, by rotating the vertical shaft 34, the medical staff can easily adjust the position of the placement rack 2 above the base 1 without complicated operations or additional tools. This not only improves work efficiency, but also reduces the difficulty of operation for medical staff, making the entire blood drawing process smoother and more efficient. In addition, when the position of the placement rack 2 above the base 1 is adjusted to a suitable position, the vertical shaft 34 stops rotating, and the movable slide 32 will remain in a fixed position and will not slide due to the weight or slight movement of the arm. This ensures the stability of the arm during the entire blood drawing process, further improving the success rate and safety of blood drawing.

[0028] In some specific embodiments, in order to realize the automation of the position adjustment of the placement rack 2 on the base 1 and further improve the accuracy and stability of the position adjustment of the placement rack 2 on the base 1, the position limiting fixture also includes a rotating motor 35 and a motor seat, the rotating motor 35 is fixedly arranged at one end of the position limiting bracket 31 through the motor seat, and the output end of the rotating motor 35 passes through the position limiting bracket 31 and is coaxially fixedly connected with the vertical shaft 34 in the slide 33. By setting the rotating motor 35, the automation of the position adjustment of the placement rack 2 on the base 1 is realized. The medical staff only needs to issue instructions through the control panel or remote control, and the rotating motor 35 can drive the vertical shaft 34 to rotate, thereby adjusting the position of the movable slide 32 and the placement rack 2 on the base 1. This automated operation greatly improves work efficiency and reduces the workload of medical staff. At the same time, the precise control of the rotating motor 35 ensures the accuracy and stability of the position adjustment of the placement rack 2 on the base 1. Medical staff can accurately set the appropriate position according to the patient's body shape and arm length, and then the rotating motor 35 automatically completes the adjustment. This precise control reduces the error of human operation and further reduces the risk of blood drawing. In addition, similar to the manual adjustment method, when the rotary motor 35 drives the vertical shaft 34 to rotate to a suitable position, the movable slide 32 will remain in a fixed position due to the locking effect of the thread. This height locking function ensures the stability of the arm during the entire blood drawing process, improving the success rate and safety of blood drawing.

[0029] In some specific embodiments, in order to increase the patient's comfort when blood is drawn and improve the blood drawing efficiency of medical staff, the movable slide 32 includes a sliding seat 36, a horizontal rotating shaft 37 and a rotating table 38, wherein the sliding seat 36 is slidably arranged in the slide groove 33, the horizontal rotating shaft 37 is horizontally arranged on the sliding seat 36, and the middle part of the rotating table 38 is provided with a rotating hole in a horizontal state, and the rotating table 38 is rotatably arranged on the horizontal rotating shaft 37 through the rotating hole. Through the rotational cooperation of the horizontal rotating shaft 37 and the rotating table 38, the angle change of the placement frame 2 set on the rotating table 38 is realized, so that the patient's arm can be placed at a more natural and comfortable angle. This helps to reduce the patient's discomfort and tension during the blood drawing process, and improves the patient's comfort and satisfaction. At the same time, by adjusting the angle of the placement frame 2, the patient's blood vessels can be more exposed and easy to locate. This helps medical staff to find blood vessels faster and perform blood drawing operations, thereby improving blood drawing efficiency and success rate. In order to ensure that the sliding seat 36 can be positioned in the sliding groove 33 , the through hole is formed on the sliding seat 36 .

[0030] In some specific embodiments, in order to enhance the stability and safety of the angle adjustment of the placement rack 2, the movable slide 32 further includes a locking member 39, an outer thread is provided on the outer side of one end of the horizontal shaft 37, an opening is provided in the middle of the locking member 39, the opening is through-shaped, and the horizontal shaft 37 passes through the opening, and an inner thread is provided in the opening to match the outer thread of the horizontal shaft 37. By rotating the locking member 39 to make it match the outer thread of the horizontal shaft 37, the angle of the rotating table 38 is fixed, thereby ensuring the stability of the rotating table 38 during the blood drawing process, enhancing the safety of the angle adjustment of the placement rack 2, avoiding the angle change caused by the movement of the patient or the weight of the arm, and further improving the reliability of the blood drawing process. At the same time, medical staff only need to simply put the locking member 39 on one end of the horizontal shaft 37 and rotate it to easily fix the angle of the rotating table 38. This operation method is simple and fast, does not require additional tools or complicated steps, and improves work efficiency.

[0031] In some specific embodiments, in order to enhance the safety of the patient when blood is drawn and improve the blood drawing efficiency of medical staff, the limiting mechanism 4 includes a tie belt 41 and a limiting buckle 42, one end of the tie belt 41 is fixedly arranged on one side of the placement rack 2, the limiting buckle 42 is fixedly arranged on the other side of the placement rack 2, and the other end of the tie belt 41 cooperates with the limiting buckle 42. The patient's arm is fixed on the placement rack 2 by the tie belt 41 and the limiting buckle 42, so that the patient's arm can remain stable during the blood drawing process, and prevent accidents caused by arm movement, such as needle shedding, blood vessel rupture, etc. Thereby ensuring the safety of the blood drawing process and reducing medical risks. At the same time, by fixing the patient's arm on the placement rack 2 by the tie belt 41 and the limiting buckle 42, medical staff can find the blood vessel more accurately and perform blood drawing operations. This stability reduces the time for medical staff to find blood vessels and improves the efficiency of blood drawing.

[0032] In some specific embodiments, in order to improve the comfort of the patient's arm when it is fixed, the restraint belt 41 is made of elastic material. The elastic material has good elasticity and resilience, and can be adaptively adjusted according to the thickness and shape of the patient's arm. As a result, the restraint belt 41 can provide uniform pressure distribution when fixing the arm, reduce the pressure points on the arm, and thus improve the comfort of the patient. At the same time, since the elastic material has a large range of expansion and contraction, the restraint belt 41 can adapt to patients with different arm sizes and shapes. This makes the limiting mechanism 4 more widely applicable to various patients, improving the versatility and practicality of the limiting mechanism 4.

[0033] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0034] In actual use, medical personnel rotate the vertical shaft 34 through the rotating motor 35 to adjust the position of the movable slide 32 on the limit bracket 31, thereby adjusting the position of the placement rack 2 on the base 1, so that the placement rack 2 can adapt to patients of different body shapes and arm lengths. At the same time, the tilt angle of the placement rack 2 set on the rotating table 38 is adjusted by rotating the rotating table 38 on the horizontal shaft 37, and then the rotation of the rotating table 38 on the horizontal shaft 37 is locked by the locking member 39, thereby locking the tilt angle of the placement rack 2 set on the rotating table 38. In addition, the patient's arm is fixed to the placement rack 2 by the restraint belt 41, so as to ensure that the patient's arm remains stable during the blood drawing process.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
