Problems solved by technology

[0004] Because children are lively and active by nature, and have fear and resistance to needles, it is often necessary to use auxiliary fixation devices for blood drawing when testing children's blood. Due to the different physical development of children, there is a gap in height between children of the same age. It may be very large, which will lead to differences in the length and thickness of the child's arms, which will lead to reduced practicality and poor flexibility of the existing auxiliary fixation device for blood drawing, and there are certain deficiencies

Embodiment 1

[0025] see Figure 1-4 , an auxiliary fixing device for pediatric blood drawing, comprising a forearm fixing mechanism, the forearm fixing mechanism includes a concave plate 1, a convex plate 2, a forearm fixing belt 5, a first slide bar 6, and a first limit block 7 and a spring 8, the front end of the concave plate 1 is provided with a groove, the rear end of the convex plate 2 is fixedly connected with a bump 3 which is slidingly fitted with the groove, and the side of the bump 3 away from the convex plate 2 is equidistantly set There are several first chute, the first stop block 7 is slidably connected in the first chute, and the first stop block 7 is fixedly connected with the inner surface of the groove at the front end of the concave plate 1. Rod 6, a spring 8 is fixedly connected between the side of the protrusion 3 away from the convex plate 2 and the inner surface of the groove at the front end of the concave plate 1, and the spring 8 is sleeved on the outer surface o...

Embodiment 2

[0030] This embodiment is a further improvement made on the basis of Embodiment 1, specifically as follows:

[0031] see Figure 1-4 The side of the concave plate 1 away from the convex plate 2 is fixedly connected with a boom fixing mechanism, the boom fixing mechanism includes a bottom plate 15, and the top surface of the bottom plate 15 is provided with a rectangular groove, and the inner cavity of the rectangular groove is close to the concave One side of the plate 1 is hinged with a large arm fixed plate 16 , and an angle adjustment mechanism is arranged in the rectangular groove, and the angle adjustment mechanism is movably connected with the bottom surface of the large arm fixed plate 16 .

[0032] The angle adjustment mechanism includes a rotating rod 17, a first helical gear 18, a second helical gear 19, a screw mandrel 20, a rotating handle 21, a slider 22 and a connecting rod 23, and the bottom surface of the big arm fixing plate 16 is away from the hinge. One end...

Abstract

The invention discloses an auxiliary fixing device for pediatric blood drawing. The auxiliary fixing device comprises a forearm fixing mechanism; the forearm fixing mechanism includes a recess plate,a protrusion plate, a forearm fixing belt, a first sliding rod, a first limiting block and a spring. According to the auxiliary fixing device, the distance between the recess plate and the protrusionplate is adjusted by outwards stretching a protrusion block; after adjustment, the spring is stretched; second limiting blocks are inserted into limiting groove to lock the protrusion block, and thenthe forearm of a child can be conveniently fixed; pull rings are pulled after blood drawing is finished, and accordingly, the second limiting blocks are driven by second sliding rods to separate fromthe limiting grooves; and under the reset action of the spring, the protrusion block automatically retracts, thereby solving the problem that an existing auxiliary fixing device for pediatric blood drawing has poor practicality due to the fact that the height difference of children of the same age may be large due to different physical development of children to result in that the arms of the children are different in length.

Description

technical field [0001] The invention relates to the technical field of pediatric medical auxiliary equipment, in particular to an auxiliary fixing device for pediatric blood drawing. Background technique [0002] Pediatrics is a comprehensive medical science that comprehensively studies the physical and mental development, health care and disease prevention and treatment of children. Pediatrics covers all health and hygiene issues related to childhood and adolescence. The object of its treatment is in the growth and development stage. [0003] The task of pediatrics is to continuously explore the theory of pediatric medicine, reduce morbidity and mortality on the basis of practice, enhance the physical fitness of children and adolescents, and improve the level of child and adolescent health care and disease prevention and control. [0004] Because children are lively and active by nature, and have fear and resistance to needles, it is often necessary to use auxiliary fixat...
