Abstract
The utility model relates to a medical instrument, in particular to a disposable, block-proof and negative pressure suction baspirator tip. The technical problems that the utility model aims to solve are that a pipette is improved; the problem that the stream guiding holes are easily blocked is solved so that the injury is avoided from being caused to the patients so as to result in that the operation is normally implemented. The utility model is provided with a pipette and a plurality of stream guiding holes are arranged at the front end of the pipette. The utility model is characterized in that a groove is arranged at the front end of the pipette and the stream guiding holes are arranged at the bottom of the groove. Because the groove is arranged on the pipette and the stream guiding holes are arranged at the bottom of the groove, the human tissues or organs are caused to be separated from the stream guiding holes, and so the stream guiding holes do not contact wit the human tissues or organs in the process of using the utility model, thus the stream guiding holes are not absorbed together with the human tissues, thus solving the problem that the suction aspirator tip is easily blocked. The stream guiding holes discharge liquid smoothly, thus being beneficial to the normal implementation of the operation.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of disposable anti-blocking vacuum extractor head that uses in abdominals such as abdominal surgery and department of obstetrics and gynecology.
Background technology
Vacuum extractor extensive use in abdominals such as abdominal surgery, department of obstetrics and gynecology.Vacuum extractor mainly is made up of two parts, and the one, the mechanical part of generation negative pressure, the 2nd, suction aspirator tip.The suction aspirator tip of clinical practice at present, no matter make of metal, or with plastic production, its structure is bushing type, promptly be made up of interior pipe, outer tube and union joint, interior pipe is positioned among the outer tube, the rear end of pipe and outer tube in union joint is installed in, and be connected with stream guiding tube, pod apertures is arranged on the front end of outer tube.Liquid enters into outer tube through pod apertures, and interior pipe of process and stream guiding tube enter into the receiver of vacuum extractor again.The problem that this suction aspirator tip exists is: in the abdominal, when inhaling ascites, blood, abdominopelvic cavity flushing liquor, pod apertures on the outer tube directly contacts with omentum majus, intestinal tube, epiploic appendices, owing to be in negative pressure state in the outer tube, therefore, very easily adsorb tissue, human internal organ often is sucked in the pod apertures of outer tube, this not only can result in blockage, make the suction aspirator tip imbibition not smooth, normally carrying out of influence operation also may be caused unnecessary injury to the patient because of excessively attracting to cause the damage of human abdominal cavity internal organs.
Summary of the invention
The technical problems to be solved in the utility model is, pipette is improved, and solves the easy blocking problem of pod apertures, the patient damaged avoiding, and operation is normally carried out.
This utility model has a pipette, at the front end of pipette several pod apertures is arranged, and its special character is, the front end of pipette is fluted, and pod apertures is positioned at the bottom of groove.
Owing to have groove on the pipette, and pod apertures is positioned at the bottom of groove, make between tissue or internal organs and the pod apertures to isolate mutually, so, in the process of using, pod apertures can not contact with tissue or internal organs, therefore, and when carrying out vacuum suction, pod apertures can not be attached together with tissue yet, solved the easy blocking problem of suction aspirator tip, the pod apertures discharge opeing is unobstructed, and what help performing the operation normally carries out.

The specific embodiment
Embodiment 1:
As depicted in figs. 1 and 2, this utility model has a pipette 1, at the front end of pipette 1 several pod apertures 3 is arranged; The front end of described pipette 1 has several grooves 2, and groove 2 is horizontal annular recess, and has certain degree of depth; Described pod apertures 3 is positioned at the bottom of groove 2, and the pod apertures 3 and the outer surface of pipette 1 are kept apart, and avoids pod apertures 3 directly to contact with tissue, prevents its obstruction; The rear end of pipette 1 is a connection tube 4, and pipette 1 is an one with connection tube 4, prevents to leak gas between the two.
Embodiment 2:
As shown in Figure 3 and Figure 4, its structure such as embodiment 1, difference is that groove 2 is a longitudinal fluting, pod apertures 3 is arranged on the bottom of groove 2 uniformly; Pipette 1 and connection tube 4 are split type, adopt close-fitting mode to link together between the two, produce with convenient.
Embodiment 3:
As shown in Figure 5 and Figure 6, its structure such as embodiment 1, difference is that groove 2 is a helical groove, pod apertures 3 is arranged on the bottom of groove 2 uniformly; Pipette 1 and connection tube 4 are split type, between the two with being threaded togather, make connect more firm between the two.
The front end of this utility model pipette 1 also can adopt the bulge-structure of other types, for example, at the front end of pipette 1 several protruding cylinders are set, pod apertures 3 is positioned on the plane of each cylinder bottom, the pod apertures 3 and the end face of each cylinder are kept apart, can realize anti-blocking purpose equally.
Claims (2)
1, a kind of disposable anti-blocking vacuum extractor head, it has a pipette, at the front end of pipette several pod apertures is arranged, and it is characterized in that the front end of pipette is fluted, and pod apertures is positioned at the bottom of groove.
2, disposable anti-blocking vacuum extractor head according to claim 1 is characterized in that, described groove is horizontal annular recess or longitudinal fluting or helical groove.
