Description

Technical Field

[0001] The utility model relates to the technical field of fixing equipment, in particular to a hand fixing device for children during vaccination. Background Art

[0002] At present, vaccination is the technology of inoculating vaccine preparations into human or animal bodies, so that the recipient can obtain immunity against a specific pathogen or a pathogen similar to the vaccine. Through the recognition of foreign substances by the immune system, antibodies are screened and manufactured to produce antibodies against the pathogen or similar pathogens, thereby making the recipient more resistant to the disease. The most common vaccination method in medicine today is injection, and the word "vaccination" comes from the smallpox vaccination technology. Its original meaning is different from today's usage, and there is also a slight gap in the scope of application in modern immunology research. It is well known that newborns will be vaccinated with multiple vaccines after birth, but because children are more resistant to injections, they are extremely resistant during the vaccination process, which is not conducive to doctors' vaccination operations.

[0003] In order to solve the above problems, a utility model patent with authorization announcement number CN207370762U discloses a hand fixation device for children's vaccination. The device has a simple structure and novel design. It can effectively fix the child's arm through the cooperation between the strap and the buckle, and has great promotion value.

[0004] However, when the device is used, the height of the device cannot be adjusted according to actual needs. For children of different heights, it is inconvenient to put their arms on the fixing block for fixing, and the use requirements cannot be well met. Utility Model Content

Based on the embodiments in 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.

[0021] Example: See Figures 1 to 3 A hand fixing device for children during vaccination, comprising: a base 1, a fixing platform 11; a lifting mechanism 5, installed between the base 1 and the fixing platform 11, and used to adjust the height of the fixing platform 11; the lifting mechanism 5 comprises a lifting sleeve 57 installed at the middle position of the upper end of the base 1, a lifting column 58 is slidably inserted in the lifting sleeve 57, the upper end of the lifting column 58 is fixedly connected to the lower end of the fixing platform 11, and a lifting component is arranged between the lifting column 58 and the lifting sleeve 57; a pair of fixing mechanisms 3 are provided, both of which are installed on the fixing platform 11, and are used to fix the child's arm; an adjusting mechanism 4 is installed on the fixing platform 11, and is used to adjust the position of the left fixing mechanism 3.

[0022] The working principle of the utility model is as follows: when in use, the height of the fixing platform 11 is adjusted by the lifting assembly. After the height of the fixing platform 11 is adjusted, the distance between a pair of fixing mechanisms 3 is adjusted by the adjusting mechanism 4. Then, the child's arm is fixed by the fixing mechanism 3, and then vaccination work can be carried out.

[0023] As a further solution, the lifting assembly includes a lifting threaded rod 54 rotatably installed in a lifting sleeve 57, a lifting groove is opened at the lower end of the lifting column 58, a lifting nut seat 56 is installed in the lifting groove, and the lifting nut seat 56 is threadedly sleeved on the lifting threaded rod 54, and a lifting hand wheel 51 is also rotatably installed on the side wall of the lifting sleeve 57, and the end of the lifting hand wheel 51 extends into the lifting sleeve 57 and is fixed with a lifting bevel gear 1 52, and a lifting bevel gear 2 53 is also installed on the lower half of the lifting threaded rod 54, and the lifting bevel gear 1 52 is meshed and connected with the lifting bevel gear 2 53, and a pair of limit seats 55 are also installed in the lower half of the lifting sleeve 57, and the height of the limit seat 55 is higher than the lifting bevel gear 1 52, so as to effectively prevent the lifting column 58 from contacting the lifting bevel gear 1 52.

[0024] The working principle of the lifting assembly is: when the height of the fixed platform 11 needs to be adjusted, the lifting hand wheel 51 is turned, and the lifting bevel gear 1 52 is driven to rotate through the lifting hand wheel 51, thereby driving the lifting bevel gear 2 53 meshing with it to rotate, and then realizing the rotation of the lifting threaded rod 54, so that the lifting nut seat 56 threadedly mounted on the lifting threaded rod 54 drives the lifting column 58 to move, and the lifting column 58 can be lifted and lowered by the forward and reverse rotation of the lifting hand wheel 51, thereby realizing the adjustment of the height of the fixed platform 11, so as to facilitate the fixing mechanism 3 to fix the arms of children of different heights.

[0025] As a further solution, a support mechanism 2 is also installed between the base 1 and the fixed platform 11, and the support mechanism 2 includes a support sleeve 21 installed on the upper end of the base 1, and a support rod 23 is installed at the lower end of the fixed platform 11. The support rod 23 is slidably inserted in the support sleeve 21, and a support bolt 22 is threadedly screwed on the outer side of the support sleeve 21.

[0026] The working principle of the support mechanism 2 is: when the height of the fixed platform 11 needs to be adjusted, the support bolt 22 can be loosened to adjust the height of the fixed platform 11. After the height of the fixed platform 11 is adjusted, the support bolt 22 is rotated to make the end of the support bolt 22 contact with the end of the support rod 23, and the locking work can be completed, thereby completing the support work of the fixed platform 11 and improving the stability of the fixed platform 11.

[0027] As a further solution, the fixing mechanism 3 includes a fixing seat 31, and an arc-shaped placement groove is provided on the fixing seat 31. Multiple sets of fixing sleeves 32 are installed on the front and rear sides of each fixing seat 31, and a fixing belt 33 is installed in each fixing sleeve 32, wherein a female Velcro 35 is installed on the upper end of the fixing belt 33 on the rear side, and a sub Velcro 34 is installed on the lower end of the fixing belt 33 on the front side, and a soft pad 36 is installed in the arc-shaped placement groove. In this embodiment, one fixing mechanism 3 is installed on the right side of the fixing platform 11, and the other fixing mechanism 3 is installed on the left side of the fixing platform 11 through the adjustment mechanism 4.

[0028] The working principle of the fixing mechanism 3 is: when fixing, put the child's arm into the arc-shaped placement groove, then stick the mother Velcro 34 at the upper end of the fixing belt 33 to the corresponding child Velcro 34 to complete the fixation of the child's arm. The soft pad 36 installed in the arc-shaped placement groove can reduce the discomfort caused to the child's arm during fixation.

[0029] As a further solution, the adjustment mechanism 4 includes an adjustment slot 44 opened at the left side of the upper end of the fixed platform 11, and an adjustment screw 41 is rotatably installed in the adjustment slot 44. An adjustment slide 46 is threadedly mounted on the upper end of the adjustment screw 41, and the upper end of the adjustment slide 46 is fixedly connected to the lower end of the fixed seat 31 on the left. An adjustment handwheel 43 is also rotatably installed on the left side of the fixed platform 11, and the end of the adjustment handwheel 43 is drivingly connected to the shaft end of the adjustment screw 41. An auxiliary slot 42 is also opened at the upper end of the fixed platform 11, and an auxiliary slide 45 is installed at the lower end of the fixed seat 31 on the left, and the auxiliary slide 45 is slidably installed in the auxiliary slot 42.

[0030] The working principle of the adjustment mechanism 4: when adjusting, turn the adjustment hand wheel 43, and the adjustment screw 41 is driven to rotate by the adjustment hand wheel 43, so that the adjustment slide 46 threaded on the adjustment screw 41 drives the fixed seat 31 on the left to move, thereby completing the adjustment of the distance between the fixed seats 31, which is convenient for fixing children with different arm lengths, and can better meet the use requirements.
