Furthermore, be equipped with distraction device on the rubber tube, and distraction device includes the sliding ring, and sliding ring sliding connection is in the outside of rubber tube, and one side of sliding ring is fixed with a plurality of screwed pipes through the bolt.

Furthermore, the internal thread of the threaded pipe is connected with a threaded rod, and the length of the threaded rod is greater than that of the threaded pipe.

Furthermore, the top welding of threaded rod has the block rubber, and the block rubber keeps away from the width of threaded rod one end and is greater than the width that is close to threaded rod one end.

The utility model has the advantages that:

1. can carry out the negative pressure with the rubber tube cooperation through the setting of negative pressure gasbag and bleed to make the negative sucker can directly adsorb cervical department, carry out the tractive of not creating to it, make things convenient for subsequent work, the security is high.

2. Through the setting of water injection pipe can be with water injection in the rubber tube to clean patient's cervix, improved the variety of device function.

3. The setting through the threaded rod can cooperate with the screwed pipe, adjusts the position of block rubber to strut patient's vaginal opening, can adjust the size of strutting according to the needs of difference in addition, can make things convenient for the removal of rubber tube when strutting through the setting of sliding ring, do not delay tractive work, convenient to use.

In the figure: the device comprises a rubber tube 1, a negative pressure air bag 2, a water injection tube 3, a negative pressure sucker 4, a distraction device 6, a slip ring 7, a threaded tube 8, a threaded rod 9 and a rubber block 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1, a noninvasive cervical traction apparatus, including rubber tube 1, the one end of rubber tube 1 bonds and has negative pressure gasbag 2, breathes in, and the other end of rubber tube 1 bonds and has negative sucker 4, conveniently adsorbs in cervical department, carries out the tractive work, and negative sucker 4, rubber tube 1 and negative pressure gasbag 2 are linked together.

The diameter of the negative pressure sucker 4 is larger than that of the negative pressure air bag 2, one side of the rubber tube 1 is welded with the water injection tube 3, and the water injection tube 3 is obliquely arranged.
