Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment, in particular to an auxiliary device that is convenient for vaccination. Background Art

[0002] As we all know, vaccination is the technology of injecting vaccines into the human body so that the recipient can gain immunity against a specific pathogen or pathogens similar to the vaccine. Young children will be vaccinated with multiple vaccines after birth, and young children will also be vaccinated.

[0003] However, young children are more resistant to injections, making it difficult for medical staff to effectively fix their arms. Moreover, young children's arms are relatively fragile. When using straps to fix their arms, excessive force may cause bruises on the arms. A smaller force may make it impossible to fix the arms, which is not conducive to the vaccination operation, thereby reducing the vaccination progress and greatly reducing the vaccination efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that young children are more resistant to injections, so that medical staff cannot effectively fix the arms of young children, which is not conducive to the vaccination operation, and to propose an auxiliary device that facilitates vaccination.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Design an auxiliary device for facilitating vaccination, comprising two bases, wherein a plurality of supporting legs are installed at the bottom of one of the bases, the two bases are hinged, four clamping plates are placed on the two bases, and a moving mechanism is arranged on the two bases, and the moving mechanisms on the two bases are connected with the four clamping plates;

[0007] The moving mechanism includes four grooves opened on the base, there are gaps between the four grooves, the four grooves are symmetrically arranged, moving blocks are slidably arranged in the four grooves, connecting mechanisms are arranged between the four moving blocks and the four clamping plates, two bidirectional screws are rotatably installed on the base, the moving blocks are threadedly connected to the two threaded ends of the two bidirectional screws, and a driving mechanism is arranged between the two bidirectional screws.

[0008] Preferably, the connecting mechanism includes a sliding rod placed on one side of the moving block, one end of the sliding rod slides through the moving block and is installed with a hinge seat, the clamping plate is hinged on the hinge seat, and the bottom of the hinge seat is slidably arranged on the base.

[0009] Preferably, a wear-resistant coating is provided on the bottom of the hinge seat.

[0010] Preferably, the driving mechanism includes a rotating rod installed at one end of two bidirectional screws, transmission wheels are installed on the two rotating rods, a transmission belt is installed between the two transmission wheels, a motor is installed on one side of the base, and the output shaft of the motor is connected to one end of one of the bidirectional screws.

[0011] Preferably, a spring is installed on one side of the moving block, the other end of the spring is pressed on the hinge seat, a long rod is installed on one end of the hinge seat, one end of the long rod slides through the moving block, and a scale groove is provided on the long rod.

[0012] Preferably, the four clamping plates are all made of medical rubber material, and one side of the four clamping plates is opened in an arc shape.

[0013] Preferably, adsorption pads are provided at the bottoms of several of the supporting legs.

[0014] The utility model provides an auxiliary device for facilitating vaccination, which has the beneficial effect that the auxiliary device for facilitating vaccination clamps the arms of young children through four clamping plates. When the clamping force of the paired clamping plates on the arms of young children is too large, the driving wheels on the bidirectional screws here will be in a slipping state, so that the paired clamping plates will not exert too much squeezing force on the arms of young children. The arms of young children will not feel pain during the squeezing process, and the probability of bruises on the arms of young children is reduced, so that the children will not shake around when getting injections, which makes it easier for medical staff to give injections to young children, thereby improving the efficiency of medical staff in vaccinating young children.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 , an auxiliary device for facilitating vaccination, comprising two bases 1, wherein a plurality of supporting legs 2 are installed at the bottom of one of the bases 1, four clamping plates 3 are placed on the two bases 1, and a moving mechanism is arranged on the two bases 1, and the moving mechanisms on the two bases 1 are connected to the four clamping plates 3; the moving mechanism comprises four grooves 4 opened on the base 1, there are intervals between the four grooves 4, the four grooves 4 are symmetrically arranged, moving blocks 5 are slidably arranged in the four grooves 4, and a connecting mechanism is arranged between the four moving blocks 5 and the four clamping plates 3, two bidirectional screws 6 are rotatably installed on the base 1, the two threaded ends of the two bidirectional screws 6 are threadedly connected with the moving blocks 5, a driving mechanism is arranged between the two bidirectional screws 6, the driving mechanism comprises a rotating rod 9 fixedly installed at one end of the two bidirectional screws 6, a transmission wheel 10 is fixedly installed on the two rotating rods 9, a transmission belt 11 is installed between the two transmission wheels 10, a motor 12 is fixedly installed on one side of the base 1, and the output shaft of the motor 12 is connected to one end of one of the bidirectional screws 6.

[0023] The torque provided by the motor 12 is no more than 7N, the friction between the two transmission wheels 10 and the transmission belt 11 is no more than 6N, the force required for the moving blocks 5 to move on the bidirectional screw 6 is no more than 4N, and the friction force of the articulated seats 8 to move on the base is no more than 1N, so that the four clamping plates 3 will not clamp the child's arms for more than 7N, thereby avoiding the occurrence of excessive clamping force.

[0024] Before using the utility model, the position of the motor 12 needs to be adjusted to prevent the bidirectional screw 6 at the motor 12 from stopping moving first; after the arm of the child who needs to be vaccinated is placed on one of the bases 1, the child's back arm will fit on the other base 1, and the two motors 12 will be operated through the external control switch, and the output shafts of the two motors 12 will drive one of the bidirectional screws 6 to rotate, and one of the bidirectional screws 6 on the two bases 1 will drive the other drive rod 9 to rotate through one of the drive rods 9, the two drive wheels 10, and the drive belt 11, so that the two bidirectional screws 6 on the two bases 1 move at the same time, so that the two The four clamping plates 3 on the base 1 move simultaneously, and the two clamping plates 3 at the thick part of the child's arm are clamped first according to the different thickness of the child's arm at different positions, so that the bidirectional screw 6 at this position stops moving, but the motor 12 does not stop moving, so that the other bidirectional screw 6 on the two bases 1 continues to rotate, so that the other two clamping plates 3 on the two bases 1 clamp the child's arm, so that the child's arm is fixed on the base 1, so that the child will not shake when the medical staff injects the child, thereby improving the efficiency of the medical staff in vaccinating the child;

[0025] Moreover, the bidirectional screw 6 at the place where the child's arm is first clamped will stop rotating, so that the transmission rod 9 and the transmission wheel 10 on the bidirectional screw 6 will stop moving, that is, the transmission wheel 10 will be in a slipping state relative to the transmission belt 11, so that excessive squeezing force will not be applied to the place where the child's arm is first clamped, the child will not feel pain during the squeezing process, and the chance of bruises on the child's arm is reduced.

[0026] Example 2

[0027] In Example 1, although the transmission wheel 10 at one of the bidirectional screws 6 slips, the clamping force of the clamping plate 3 on the child's arm is still difficult to determine. Based on Example 1, optimization is performed. Figure 1-4 The connecting mechanism includes a sliding rod 7 placed on one side of the moving block 5, one end of the sliding rod 7 is threaded through the moving block 5 and an articulated seat 8 is installed through a bearing, a clamping plate 3 is hinged on the articulated seat 8, the bottom of the articulated seat 8 is slidably arranged on the base 1, a wear-resistant coating is arranged at the bottom of the articulated seat 8, and the wear-resistant coating is formed by spraying ceramic particles, so that the bottom of the articulated seat 8 is more wear-resistant, a spring 14 is fixedly installed on one side of the moving block 5, the other end of the spring 14 is squeezed on the articulated seat 8, a long rod 15 is installed at one end of the articulated seat 8, one end of the long rod 15 slides through the moving block 5, a scale groove 16 is arranged on the long rod 15, and a retaining ring is installed at the other end of the sliding rod 7, so that the sliding rod 7 will not fall off the moving block 5.

[0028] The provided sliding rod 7 can limit the spring 14, thereby reducing the lateral bending of the spring 14, making the feedback of the elastic extrusion force at the spring 14 more accurate;

[0029] The hinged connection of the clamping plate 3 by the hinged seat 8 allows the clamping plate 3 to rotate according to the condition of the arm after being squeezed by the arm, so that the inner side of the clamping plate 3 adapts to the arm, making the clamping force of the clamping plate 3 of the device on the arm more uniform.

[0030] By setting the sliding rod 7, after the clamping plate 3 in Example 1 clamps the child's arm, the sliding rod 7 will move, thereby causing the spring 14 to contract and allowing a portion of the long rod 15 to extend out of the moving block 5. Combined with the scale groove 16 on the long rod 15 relative to the moving block 5, the size of the squeezing force can be read, thereby making it easy to know the squeezing force of the device on the child's arm.

[0031] Example 3

[0032] Based on the optimization of Example 1-2, refer to Figure 1-4 The motor 12 is set as a low-torque motor, the four clamping plates 3 are made of medical rubber material, one side of the four clamping plates 3 is opened in an arc shape, and the bottom of the supporting legs 2 is provided with an adsorption pad 13.

[0033] The motor 12 is set as a low-torque motor so that the motor 12 can stop rotating more easily. That is, when the child's arm is subjected to a squeezing force exceeding the limit, the motor 12 will stop rotating, so that the child's arm will not feel pain during the squeezing process.

[0034] One side of the four clamping plates 3 is opened into an arc shape, combined with the attached Figure 3 It can be seen that after the arm is fixed by the four clamping plates 3, it is not easy for the arm to be separated from the four clamping plates 3, so that the medical staff can be more focused during the process of vaccinating the young children.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
