Description

Cervical anesthetic device

Technical Field

The utility model relates to a medical equipment technical field of gynaecology, concretely relates to cervical anesthesia ware.

Background

The cervix is a part between the uterus and the vagina, before the cervix is operated, the cervix of a patient needs to be locally or completely anesthetized, and because the cervix contains a plurality of nerve endings, organ injury is easily caused by local injection of anesthetic. Therefore, except for general vein anesthesia, local anesthesia mostly adopts a mode of applying a mixed liquid medicine of lidocaine and bupivacaine or lidocaine cream to perform osmotic anesthesia, the specific anesthesia operation is to expand the vagina by using an extending device and then apply medicine by using a long rod cotton swab, and the mode is not only difficult to uniformly distribute medicine on the outer wall of the cervix, but also difficult to accurately find a medicine application point under the condition that the region of cervicitis needs to avoid anesthesia. Although devices for administering drugs in a partially injected form have been developed subsequently, the effect is still not satisfactory in terms of uniformity of drug application and accuracy of the site of administration.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: overcomes the defects of the prior smearing type cervical anesthesia medicine administration technology, and provides the cervical anesthesia device which has the advantages of uniform medicine coating, accurate medicine administration position and shielding effect on the uterine cavity.

In order to solve the technical problem, the cervical anesthesia apparatus comprises an outer cylinder, a medicine injection pipe and a push rod, wherein the medicine injection pipe is arranged in the outer cylinder in a penetrating manner, the push rod is arranged in the medicine injection pipe, and brush hairs are circumferentially distributed at the top of the outer cylinder; the top of the medicine injection tube is provided with an expanded medicine outlet head, and medicine outlet holes are distributed on the medicine outlet head; the upper end face and the lower end face of the outer barrel are provided with guide necks, the medicine injection pipe is arranged in the guide necks in a sliding mode, and the lower end of the medicine injection pipe is provided with an anti-return conical edge.

In order to facilitate the equipment to be placed and pushed, the top of the medicine outlet head is an arc surface, the outer wall of the cervix is covered by the bristles in a radial shape, and the bottom of the medicine outlet head is in an inverted cone shape.

In order to prevent the vagina wall from being scratched in the propelling process, the junction of the top and the bottom of the medicine outlet head is in smooth transition.

In order to master the pushing-in dosage, the top end of the push rod is provided with a rubber head, and the tail end of the push rod is provided with scales.

The rotary tooth is integrally formed at the bottom of the outer barrel for facilitating the operation of brushing liquid medicine or ointment on the brush, and the ear part is integrally formed at the bottom of the medicine injection tube for facilitating the pushing of the liquid medicine or ointment.

In order to meet the safety and health requirements of the internal implanted device, the outer barrel, the medicine injection pipe and the push rod are made of medical PE injection molding profiles, and the bristles are arc-shaped silica gel brushes.
