Compared with the prior art, the nasal cavity adsorption device has the technical effects that the end face of the protruding portion is designed to be a plane, a larger space is reserved between the cavity wall of the nasal cavity and the end face of the protruding portion, the cavity wall of the nasal cavity is not easy to stick to the adsorption channel to block the inlet of the adsorption channel, and adsorption is convenient.
Description
Technical Field
The utility model relates to a medical appliance, in particular to a disposable nasal cavity suction and cleaning connector used in clinical nasal cavity suction.
Background
At present, rhinitis and nasosinusitis are treated by adopting an operation method for radical treatment, and in the operation process, as pus generated by nasal mucosa of a patient is accumulated in a nasal cavity, doctors need to clean the pus generated by the nasal mucosa.
Therefore, the inventor has invented a disposable nasal cavity suction connector (see the chinese patent with publication number CN 204501814U) in 2015, which is convenient for the vacuum extractor to quickly absorb and clean nasal cavity pus, or inject water, normal saline or liquid medicine for cleaning.
SUMMERY OF THE UTILITY MODEL
The technical problems to be solved by the utility model are as follows: the disposable nasal cavity suction and cleaning connector is provided with the convex part, although the convex part can reach a far position in the nasal cavity, the nasal cavity at the position is very narrow, the cavity wall of the nasal cavity can contract inwards under the external suction effect, the cavity wall of the nasal cavity is easily attached to the adsorption channel to block the inlet of the adsorption channel, and the adsorption cannot be carried out.
The technical scheme of the utility model is as follows:
a disposable nasal cavity suction and cleaning connector comprises a connector body, wherein the upper end of the connector body is a head end, and the head end is in a conical shape with a small outer part and a large inner part; the lower end of the connector body is a tail handle; the connector body is provided with an adsorption channel at the center, two ends of the adsorption channel are through, a protrusion part extends outwards from the center area of the top end of the head end, and the outer end face of the protrusion part is a plane.
The inlet end of the adsorption channel is in a horn shape with a large outside and a small inside.
The connector body and the protrusion are integrally formed.
The surface of the head end is a smooth curved surface.
The tail handle is step-shaped.
Compared with the prior art, the nasal cavity adsorption device has the technical effects that the end face of the protruding portion is designed to be a plane, a larger space is formed between the cavity wall of the nasal cavity and the end face of the protruding portion, the cavity wall of the nasal cavity is not easy to stick to the adsorption channel to block the inlet of the adsorption channel, and adsorption is convenient.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.
Referring to fig. 1-2, a disposable nasal cavity suction and cleaning connector comprises a connector body 10, wherein the upper end of the connector body 10 is a head end 20, and the head end 20 is in a conical shape with a small outer part and a large inner part; the lower end of the connector body 10 is a tail handle 30; the center of the connector body 10 is provided with an adsorption channel 11, two ends of the adsorption channel 11 are through, a central area of the top end of the head end 20 extends outwards to form a protrusion 21, and an outer end face 22 of the protrusion 21 is a plane.
As shown in figure 3, to prevent the head end 20 from being approximately conical in shape, the tip is slightly smaller to facilitate insertion into the patient's nostril.
In order to facilitate the operation that the wall of the nasal cavity is stuck to the adsorption channel or the foreign matters in the nasal pus block the inlet of the adsorption channel 11, the inlet end of the adsorption channel 11 is in a horn shape 12 with a large outside and a small inside.
The connector body 10 is integrally formed with the protrusion 21 for the sake of firmness and ease of processing.
For ease of operation, the surface of the head end 20 is smoothly curved.
In order to fit various models conveniently, the tail handle 30 is step-shaped.
The working principle is as follows:
when suction is needed, the tail handle 30 is connected with the negative pressure suction apparatus, the protruding part 21 and the front end of the head end 20 are inserted into the nasal cavity of a patient, the nasal cavity can reach a farther position of the nasal cavity due to the protruding part 21, meanwhile, the rear end of the head end 20 is blocked at the nasal cavity, so that the nasal cavity is a closed space, and under the suction effect of the negative pressure suction apparatus, the nasal cavity pus can be conveniently and quickly adsorbed and cleaned by the negative pressure suction apparatus.
In use, even the chamber wall of nasal cavity can inwards contract, because there is great space between the outer terminal surface 22 of nasal cavity and bellying 21, the chamber wall can not be attached at the entry end of adsorption channel 11, and the entry end is loudspeaker form in addition, and the chamber wall can not all block up the entry of channel 11, does not influence absorption.
When the nasal cavity cleaning device needs cleaning, the tail handle 30 is connected with the injector, the protruding part 21 and the front end of the head end 20 are inserted into the nasal cavity of a patient, the protruding part 21 is arranged, the nasal cavity can be farther away, meanwhile, the rear end of the head end 20 is blocked at the nasal cavity, the nasal cavity is a closed space, and the nasal cavity can be conveniently cleaned under the pressure action of the injector.
See the prior art for further details.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be construed as the protection scope of the present invention.
