Abstract
The utility model discloses a drug delivery device for cervical canal topical anesthesia. The drug delivery device comprises a tube body arranged on a syringe through a needle holder, wherein, bumps are uniformly distributed on the circumferential surface on the front part of the tube body; and liquid permeable holes communicated with the inner cavity of the tube body are arranged on the bumps. The tube body is arranged on the syringe through the needle holder; the bumps on the surface of the tube body can keep sufficient contact with the cervical canal surface when the tube body enters the cervical canal; and drug is added into the inner cavity of the tube body slowly by the syringe and can be uniformly sprayed on the cervical canal surface through the liquid permeable holes, thereby achieving uniform cervical canal topical anesthesia, and facilitating normal progress of the operation. Accordingly, the operation can be conducted in the presence of the safe dosage of anesthetic, and the anesthetic cost can be lowered.
Description
Technical field
This utility model relates to a kind of anesthesia utensil, specifically is a kind of cervical canal topical anesthesia doser.
Background technology
Anesthesia is a preoperative operating technology important and requirement is very strict.The present cervical canal topical anesthesia administrator that on hospital clinical, generally uses, it comprises body, the front portion of body is provided with liquid drain hole, because body is the plastic tube body of a slyness, and itself and cervical canal can not be fitted closely, the anesthesia medicinal liquid that ejects from liquid drain hole is difficult to affact uniformly on the cervical canal surface, so anaesthetic effect is imprecise, what be unfavorable for performing the operation normally carries out.
The utility model content
The technical problems to be solved in the utility model provides a kind of cervical canal topical anesthesia doser that can make anesthesia medicinal liquid uniformly penetrating to the cervical canal surface.
For solving the problems of the technologies described above, the cervical canal topical anesthesia doser that is provided comprises body, and body is installed on the syringe by needle stand, its construction features is: be evenly equipped with projection on the forward circumferential surface of described body, projection is provided with the liquid drain hole that communicates with tube cavity.
After adopting said structure, owing to be evenly equipped with projection on the forward circumferential surface of body, projection is provided with the liquid drain hole that communicates with tube cavity, body is installed on the syringe by needle stand, after body enters in the cervical canal, the projection on body surface can contact with the cervical canal surface is very sufficient, slowly push away medicine by syringe to tube cavity, by liquid drain hole can be uniformly with medicine liquid spray on the cervical canal surface, can make the cervical canal topical anesthesia even, what help performing the operation normally carries out, and patient is performed the operation under the safe dose of anesthetics, has also reduced drug cost simultaneously.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to the cutaway view that amplifies.
Among the figure: 1 is body, and 2 is needle stand, and 3 is projection, and 4 is liquid drain hole, and 5 is syringe.
The specific embodiment
Cervical canal topical anesthesia doser comprises body 1 as shown in drawings, and the rear end of body 1 is installed on the syringe 5 by needle stand 2, the inner chamber of body 1 is a transfusing chamber, the forward end seal of body 1, the front end head of body 1 is circular-arc, is convenient to stretch in the cervical canal.Be evenly equipped with arcuation projection 3 on the body 1 forward circumferential surface, arcuation projection 3 can be towards each orientation of body 1 circumference, and the top of arcuation projection 3 is provided with the liquid drain hole 4 that communicates with body 1 inner chamber.
