Further, one end of the push rod inserted into the shell is provided with a sealing piston.

Further, two bite-holding portions are installed at both sides of the airbag in opposition.

Further, the biting part is a silica gel piece.

Furthermore, a recess is formed in the middle of the surface of the biting part and used for fitting the shape of the molar.

Furthermore, the push rod is provided with a limiting part capable of moving along the axial direction of the push rod, the limiting part can be fixed at any position on the push rod, and the push rod is limited by one end of the limiting part attached to the shell.

Further, the outer ring of the push rod is provided with threads, a threaded hole is formed in the limiting part, and the limiting part is nested on the push rod through the threaded hole.

Furthermore, a rack is arranged on the push rod, a through hole is formed in the limiting part, the limiting part is embedded on the push rod through the through hole, and the rack is embedded in the side wall of the through hole.

Furthermore, scales are arranged on the push rod.

Further, the other end of the push rod is provided with a handle.

Compared with the prior art, the invention has the following advantages:

1. when the traction device is used, the biting part on the air bag is placed between upper and lower molars in the oral cavity of a patient, then the push rod is pushed to inflate the air bag, the air bag is expanded and supported to form traction force on masticatory muscles, and the traction can be accurately controlled through the pushing length of the push rod in the period; then the patient slightly bites the biting part, the masticatory muscles contract, and the push rod can be continuously applied with force to improve the feedback and resistance of muscle strength training; from this, therapist and patient can realize chewing muscle draft and muscle strength training simply through this device, reduce the operation degree of difficulty, improve the training effect.

2. According to the invention, the limit piece capable of being fixed in a sliding manner is arranged on the push rod, and after the masticatory muscles are stretched in place, the push rod is limited through the limit piece, so that the effects of safety and protection are achieved.

Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1, the present embodiment provides a masticatory muscle stretching and muscle strength training device, which includes an air bag 1, a bite part 2, a push rod 3, and a tubular housing 4. The push rod 3 is inserted from one end of the shell 4, a sealing piston 5 which can slide on the inner wall of the shell 4 in a sealing way is arranged at the inserted end part, so that the push rod 3 and the shell 4 form a piston structure, and the other end of the push rod 3 is provided with a handle 6. The air bag 1 is in a transverse T-shaped structure, and one single side of the air bag is communicated with the other end of the shell 4, so that when the push rod 3 slides in the shell 4, air flow in the air bag 1 can be compressed and flows, and the air bag 1 is expanded. The opposite sides of the upper and lower ends of the air bag 1 are provided with a biting part 2. The biting part 2 is made of a silicone piece, and a concave part is arranged in the middle of the surface of the biting part 2 and is used for fitting the shape of a molar; the silica gel material gives corresponding feedback during muscle strength training.

The push rod 3 is provided with a limiting part 7 capable of moving along the axial direction of the push rod 3, the limiting part 7 can be fixed at any position on the push rod 3, and the fixed limiting part 7 is attached to one end of the shell 4 to limit the movement of the push rod 3. The method specifically comprises the following steps: as shown in fig. 1, the outer ring of the push rod 3 is provided with a screw thread, the limiting member 7 is a plate-shaped structure, the center of the limiting member is provided with a screw hole, and the limiting member 7 is embedded on the push rod 3 through the screw hole; the movement on the push rod 3 is effected by rotation of the stop 7. The push rod 3 is also provided with scales 8, which is convenient for directly observing and controlling the moving distance of the push rod 3.

In another embodiment, a rack is arranged on the push rod 3, the limiting member 7 is embedded on the push rod 3 through a threaded hole, and the rack is embedded in the side wall of the through hole. The side wall of the clamping rack on the through hole can be slightly shifted and folded, the limiting part 7 can move after being shifted, and the limiting part and the rack are embedded and fixed when not shifted.

The application process of this embodiment is as follows: the shell 4 is held by hand, the air bag 1 is stretched into one side of the oral cavity, and the biting part 2 is attached to the upper and lower molars. Then the handle 6 is pushed to transmit force to the sealing piston 5 along the push rod 3, the sealing piston 5 pushes the gas in the cylinder 4 to flow to the air bag 1, the air bag 1 is inflated and expanded, the volume is changed, and therefore stretching force on masticatory muscles is formed. The amount of gas in the air bag 1 is adjusted according to the tension of masticatory muscles of each person and subjective feeling of the patient. After the adjustment is completed, the limiting part 7 is rotated to enable the limiting part 7 to be fixed at a certain position on the push rod 3 to be attached to one end of the shell 4, so that the volume of the gas in the air bag 1 is unchanged, and the expansion condition of the air bag 1 is observed and recorded through the scale 8 of the push rod 3. When a patient carries out the muscle strength training of the masticatory muscles, the upper molars and the lower molars act on the biting part 2, the masticatory muscles contract, the biting part 2 is changed in morphology, acting force in the opposite direction is generated on the masticatory muscles, the feedback and the resistance of the muscle strength training of the patient can be given at the same time, the motivation of the patient training is mobilized, and the effect of the muscle strength training is improved.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
