Description

Saliva suction tube

Technical Field

The utility model relates to the technical field of oral medical instruments, concretely relates to inhale salivary duct.

Background

The saliva suction pipe is a medical instrument which is connected with the saliva suction pipe by a negative pressure device to generate negative pressure in the oral outpatient treatment process, and the saliva suction pipe sucks and removes water mist, debris, blood and saliva in the oral cavity so as to keep the clear operation visual field in the oral cavity.

Inhale salivary duct and include suction head and flexible connecting pipe, stretch into the oral cavity through the suction head and absorb, according to the difference at absorption position, the suction head stretches into the glenoid depths or oral mucosa department etc. and absorbs, however in order to absorb the glenoid depths, inhale salivary duct and need keep great suction, and clinically because negative pressure device is far away from patient, it is inconvenient to adjust negative pressure device's negative pressure, and medical personnel often forget the adjustment negative pressure, and directly absorb the oral mucosa with inhaling salivary duct under this suction, oral mucosa is comparatively fragile, although the effect of absorption has been reached, but cause the oral mucosa damage easily.

The utility model discloses a surgery that can adjust suction attracts pipe, including attracting the pipe body, the one end of attracting the pipe body is the toper and is used for connecting the negative pressure pipe, the other end of attracting the pipe body is for attracting the head, be provided with first open slot and second open slot on the pipe wall of attracting the pipe body respectively, the both sides of first open slot and second open slot are provided with first recess and second recess respectively, the separation blade sets up in first recess and second recess, the separation blade can be followed first recess and second recess and slide the coverage area of adjusting at first open slot and second open slot. The above patent covers the first opening groove and the second opening groove by sliding the blocking piece, so as to achieve the purpose of adjusting the suction force.

Then because the separation blade is movable, adjust the angle of attracting the pipe according to the different needs in position when absorbing, when attracting the pipe up, the separation blade receives gravity reason can automatic whereabouts to be difficult to avoid the mistake to touch the separation blade and cause the removal when the operation, the separation blade can't shelter from first open slot and second open slot, causes the suction to change.

SUMMERY OF THE UTILITY MODEL

The utility model provides a inhale salivary duct to the problem that the separation blade removes to cause suction to change among the solution prior art.

In order to solve the above problem, the utility model provides a following technical scheme: the utility model provides an inhale salivary duct, includes suction head and connecting pipe, one side of suction head is equipped with the suction inlet, the opposite side and the connecting pipe of suction head are connected, the suction head is equipped with coaxial logical groove and spout, the suction head is coaxial to be cup jointed the sleeve of activity and to adjust a section of thick bamboo, telescopic inner wall and logical groove butt, sleeve and spout sliding connection, it includes cylinder section and toper section to adjust a section of thick bamboo, cylinder section and the coaxial rotation of sleeve are connected, the outer wall of suction head is equipped with many rings of external screw threads, cylinder section and external screw thread threaded connection, the sleeve is kept away from to the toper section.

The utility model discloses a theory of operation: cylinder section and many rings of external screw thread threaded connection in this application, when rotatory cylinder section, the cylinder section advances towards leading to the groove soon, because sleeve and the coaxial rotation of cylinder section are connected, sleeve and spout sliding connection, because the restriction of spout, the rotation of cylinder section can not drive the sleeve rotatory, the cylinder section promotes the sleeve and leads to the groove and remove towards, final sleeve will lead to the groove and shelter from, reach the purpose of adjusting suction head suction, because the spacing of external screw thread, make telescopic slip receive the restriction, make the suction head keep suction, and the shape of toper section is the toper, and the toper section keeps away from the sleeve, its external diameter is less, can reduce the probability that the mistake touched, prevent that the mistake from touching the rotation that causes the cylinder section.

The utility model has the advantages that: this application passes through sleeve and spout sliding connection, and sleeve and drum section rotate to be connected because the restriction of many rings of external screw threads for telescopic slip receives the restriction, and the sleeve is kept away from to the pointed end of toper section, and its external diameter is less, can reduce the mistake and touch the rotation that causes the drum section, makes the sleeve can keep sheltering from to leading to the groove, makes the suction head keep suction.

Further, the connecting pipe is sleeved with a plastic film. The plastic film can play a role in preventing cross infection, and can prevent medical staff from contacting saliva of a patient and the like to cause infection.

Further, the inner wall of the sleeve is provided with a rubber pad. The rubber pad can better fill the gap at the edge of the through groove due to soft materials, and can achieve better sealing effect.

Furthermore, the surface of the cylinder section is provided with a plurality of flexible convex parts in a staggered manner. The friction on the surface of the cylinder section can be increased by the aid of the plurality of staggered protruding portions, so that the rotating cylinder section has an acting point and is convenient to rotate.

Further, the suction port is provided with a plurality of connection pieces. The connection piece can be broken the inspiratory tissue piece, prevents that the suction inlet from plugging up, influences the adsorption effect.

Furthermore, the surface of the conical section is provided with a metal coating. Its surface of metallic coating is comparatively smooth, can prevent that the mistake from touching and rotate the toper section.

Furthermore, the through groove is connected with a boss positioned in the suction head. The boss can block liquid in the suction head and prevent seepage.

Furthermore, the suction head is provided with anti-skid lines. The anti-skid lines play a role in skid resistance, and the medical care personnel can conveniently hold the suction head.
