[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0021] Example
[0022] The blood drawing auxiliary device described in this embodiment is as follows: Figures 1 to 4 As shown, it includes a bottom plate 1, on which are disposed a plurality of groups of clamping assemblies distributed from front to back. The clamping assemblies of the utility model are two groups distributed from front to back;
[0023] like Figure 1 As shown, the clamping assembly includes two splints 3 distributed left and right, the splints 3 are in an arc-shaped structure, and the arc center is located between the two splints 3; the lower end of the splint 3 is hinged to the top of the base plate 1 and swings left and right, an elastic band 6 is arranged between the two splints 3, and the two ends of the elastic band 6 are respectively connected to the inner wall of the splint 3 and are located in the upper half of the splint 3; when the elastic band 6 is in a natural state, the two splints 3 are in an open state; an insert block 5 is fixed to the swinging end of one of the splints 3, and a slot for inserting the insert block 5 is opened at the swinging end of the other splint 3.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the swing end is one end of the splint 3 that is movable, and the other end is the hinged end. When installed, the hinged end of the corresponding splint 3 is fixed to two hinged blocks 8 that are distributed front and back on the top of the base plate 1. The hinged end of the splint 3 is provided with a hinge hole, and a hinge column is independently installed in the hinge hole. The two ends of the hinge column are respectively connected to the hinge block 8, and the hinge mode is a conventional hinge connection in the prior art. The two ends of the elastic band 6 are respectively connected to the upper half of the inner side wall of the splint 3. The opposite side of the two splints 3 in this embodiment is the inner side, and vice versa. The elastic band 6 is a conventional elastic band in the prior art, which has good elasticity. During production, the splint 3 and the elastic band 6 should have a certain width to avoid the elastic band 6 being narrow and causing a mark on the patient's arm. Of course, it does not need to be too wide, which will affect the blood drawing work of medical staff. The width of the splint 3 and the elastic band 6 is specifically 1.5cm to 3cm.
[0025] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown; the insert block 5 is fixed on the swing end of the right splint 3, and the slot is opened on the swing end of the left splint 3. When the swing ends of the two splints 3 are pressed against each other, the insert block 5 is inserted into the slot to avoid misalignment of the swing ends of the left and right splints 3. When in use, the inner side walls of the swing ends of the two splints 3 fit on the patient's arms, which can also prevent the misalignment of the two to a certain extent.
[0026] like Figure 1 As shown, a gasket 4 is provided on the inner wall of the splint 3 between one end of the corresponding elastic band 6 and the swing end of the splint 3. The gasket 4 is made of silicone material. When in use, when the splint 3 restricts the patient's arm, the gasket 4 provides a certain degree of comfort. An arm drag pad 7 is provided on the top of the base plate 1. The arm drag pad 7 is located between the two splints 3. The arm drag pad 7 is made of sponge material. The sponge material arm drag pad 7 has good resilience and softness. When the patient's arm is placed on the arm drag pad 7, it provides good comfort. At the same time, it will be compressed to different degrees according to the thickness of the patient's arm. A hand drag pad 9 is provided on the top of the base plate 1 corresponding to the front side of the arm drag pad 7. The hand drag pad 9 is made of elastic material. When in use, the patient's hand is placed on the hand drag pad 9 to increase its comfort.
[0027] like Figure 1 and Figure 4As shown, a limiting block 2 is fixed on the top of the bottom plate 1 corresponding to the outer side of each splint 3. When the two splints 3 are open, the limiting block 2 blocks the splint 3 and the splint 3 has a maximum open state. Its main purpose is to prevent the splint 3 on one side from swinging to the outside in a transitional manner. Under the traction of the elastic band 6, the splint 3 on the other side also swings accordingly, so that the splint 3 cannot stand up, thus affecting its use; the side walls of the limiting block 2 and the splint 3 that are in contact with each other are curved, which is convenient for contacting with the outer side walls of the splint 3; when the splints 3 on both sides are against the limiting block 2, the two splints 3 are in an open state, and the elastic band 6 is in a natural state.
[0028] like Figure 3 As shown, a first magnet 11 is fixed on the outer wall of the splint 3, and a second magnet 10 that is magnetically attracted to the first magnet 11 is fixed on the limit block 2; the first magnet 11 is fixed on the outer wall of the splint 3, and the second magnet 10 is fixed on the arc surface of the first magnet 11, and the two are magnetically attracted to each other. When in use, when the splint 3 is in an open state, the splint 3 is magnetically attached to the limit block 2, and has better stability.
[0029] In actual use, Figure 4 and Figure 6 As shown, the splint 3 is in an open state, and there is a gap between the two splints 3 for the patient's arm to be placed. The patient's arm is placed between the two splints 3, and the elastic band 6 is pressed down. The swing ends of the splints 3 on both sides are pulled and automatically closed inward, restricting the patient's arm between the splint 3 and the elastic band 6, and the patient's arm can be automatically fixed. When the patient's arm needs to be lifted up, since the two splints 3 are already closed and pulled by the elastic band 6, the patient cannot lift the arm from the bottom to the top, and the medical staff needs to open the splint 3 to both sides from the outside so that the patient's arm can be separated from between the splints 3; The elastic band 6 always fits the patient's arm, and is designed for arms of different thicknesses. Moreover, since the thickness of the forearm and wrist of the human body is different, the front and rear sets of splints 3 are automatically suitable for clamping arms or wrists of different thicknesses, which is better to use; the arm drag pad 7 can support and drag arms of different thicknesses with its high elasticity; of course, the elastic band 6 and the arm drag pad 7 alone cannot completely fix the patient, and are not suitable for occasions where the patient subjectively wants to break free from the fixation. The splint 3 and the elastic band 6 mainly play the role of auxiliary fixation, and are mainly used for the purpose of auxiliary fixation of the patient's arm in a relaxed state, so as to avoid the natural shaking caused by the decline of physical function of elderly patients.
