As a result, medical devices such as needles, pliers, burs and other medical devices may cause accidental injury to children's oral cavity, and some children will scratch and bite nearby medical staff while struggling, causing medical staff to be injured. Therefore, when children struggle and twist Children need to be restrained.

Traditionally, children are generally restrained by their guardians. However, in the case of long-term examinations and oral treatment, it is difficult to restrain children for a long time due to the limited strength of the guardians, and in the process of restraining children Children's head, mouth, elbows, fingernails and other parts may cause damage to guardians; on the other hand, for children aged 8 to 10 years, children's strength is large, and it is difficult for female guardians to completely restrain children , causing the child to continue to struggle during examination and treatment, so a device that can assist the guardian to restrain the child is needed.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a restraint board that assists in manually restraining children, so as to avoid children's continuous struggle and twisting during inspection and treatment.

In order to achieve the above purpose, the technical solution of the present invention is: an adjustable children's restraint board includes a telescopic unit, and the telescopic unit includes a first board body and a second board body, and the first board body is located above the second board body and is connected with the second board body. The first plate body is provided with a positioning hole, and the second plate body is fixed with a positioning rod that can be aligned with the positioning hole and is slidably connected with the positioning hole; U is provided between the first plate body and the second plate body The flexible buffer part includes a fixedly connected flexible sealing layer and a flexible buffer layer, the flexible sealing layer is located on the side of the flexible buffer layer close to the first plate body and the second plate body, and the flexible buffer part is close to the second plate body. One end is detachably connected with the second plate body, and the end of the flexible buffer part away from the second plate body is connected with a slider, the top of the first plate body is provided with a guide groove, the slider is slidably connected with the guide groove, and the guide groove is provided with a first The two ends of the first spring are respectively fixed on the side wall of the guide groove and the slider; the second plate body is provided with a negative pressure cavity, and the top of the second plate body is provided with a number of negative pressure chambers aligned with the flexible sealing layer and communicating with the negative pressure cavity.

The two ends of the pulling rope are respectively fixed on the piston and the first plate body, and the two ends of the second spring are respectively fixed on the piston and the second plate body superior.

The beneficial effects of this program are:

1. The restraint plate in this scheme can be used as a support plate when the child needs to be restrained, so that the guardian can press the child on the restraint plate, assist the guardian and medical personnel to restrain the child, thereby reducing the contact between the child and the guardian, avoiding Children cause harm to guardians. Compared with dental chairs and treatment beds, the restraint plate in this solution is smaller in size, and is more suitable for use in clinics with small space. Since it can be placed in the corner of the clinic when not in use, it can also avoid the need for medical staff. Everyday work gets in the way.

2. In this scheme, the first plate body can slide relative to the second plate body, so that the length of the restraint plate is increased, so as to adapt to children of different heights, and the adaptability is better, while the first plate body slides to the second plate When it is directly above the body, the length of the restraint plate is the smallest, and the space occupied during storage is smaller, which is more convenient for storage.

3. When the first board body slides out, the flexible buffer part covers the top of the first board body and the second board body and directly contacts with children, which acts as a buffer for children and prevents children from directly contacting the hard first board. The body and the second board are in contact, thereby improving comfort. In addition, since the flexible buffer portion is detachably connected to the second plate body, the flexible buffer portion can be removed for cleaning separately after the flexible buffer portion is dirty.

4. When not in use, in order to avoid hindering the work of medical staff, the restraint board is usually placed in the corner of the clinic. The flexible buffer part in this solution is located between the first board body and the second board body. The flexible buffer part and the second plate body play a role in shielding the flexible buffer part, preventing the flexible buffer part from directly contacting the ground, the wall or the outer wall of other medical equipment, so as to prevent the external dust from directly adhering to the flexible buffer part through contact, resulting in The flexible buffer portion is quickly dirty and needs to be cleaned again, so this solution can reduce the cleaning frequency of the flexible buffer portion and reduce the workload of medical staff.

Further, the locking portion is located at the lower end of the second plate body, and the first plate body is provided with a positioning groove for accommodating the locking portion.

The beneficial effect of this solution is: after the positioning rod is slid into the positioning hole, the locking portion is located in the positioning groove, so that the first plate body can fall to the position where the bottom is at the same height as the bottom of the second plate body, so that the first plate body can fall to the same height as the bottom of the second plate body. The plate body can completely contact the supporting plane such as the ground or the table below, and the force is better.

Further, the thickness of the first plate body is the same as that of the second plate body.

The beneficial effect of this solution is: after the positioning rod slides into the positioning hole, the first plate body slides to the side of the second plate body and is juxtaposed with the second plate body, at this time the first plate body and the top of the second plate body The formed restraint board is smoother, preventing the first board body or the second board body from bulging upwards, thereby effectively improving the comfort of use.

Further, one end of the first plate body away from the second plate body or one end of the second plate body away from the first plate body is provided with a restraint unit, the restraint unit includes two restraint belts and two locks, and the two restraint belts are located on the first plate respectively. The two sides of the body and the two locking buckles are respectively located on both sides of the first plate body, and the restraint straps are fixed on the first plate body or the second plate body.

The beneficial effect of this scheme is: when restraining the child, two restraint straps are wrapped around the child's chest in an X shape and can be fixed on the lock, thereby restraining the upper body of the child and further reducing the workload of the guardian .

Further, the restraint belt is an elastic belt.
