Abstract
The utility model relates to the field of medical apparatus, concretely to an apparatus used for carrying out the clinical treatment to a hydropericardium patient. The utility model comprising a puncture needle (1) and a sleeve tube (4). The puncture needle (1) and the sleeve tube (4) are matched. The needle wall of the puncture needle (1) is marked with a graduation (3) which can ensure the accuracy of the needle insertion deepness. The head end of the sleeve tube (4) is provided with a side hole (2), and the blocking is avoided. The puncture needle (1) is drawed off slowly after the success of puncturing. The sleeve tube (4) is indwelled in a pericardial cavity, and puncturing cardiac muscle is avoided. A cross valve (6) is arranged on the sleeve tube seat, and the sealing of a tube cavity is ensured. Accordingly, the utility model has the advantages of convenient operation, strong sealing, and high safety.
Description
Technical field this utility model relates to medical instruments field, a kind of apparatus of using when specifically the pericardial effusion patient being carried out clinic diagnosis.
Before the background technology row paracentesis pericardii, usually by ultrasonic definite depth of needle.And clinical its pin wall of used paracentesis pericardii pin does not have scale at present, the depth of needle inaccuracy, therefore easily cause puncture failure because of inserting needle is not in place, or cross because of inserting needle and deeply to stab cardiac muscle, its sharp needle point is put and is stayed in the pericardial cavity after puncturing successfully, the patient must hold the fixing fatigue that easily produces of pin for a long time during this time, thereby syringe needle is fixing not firm and displacement causes puncture failure or stabs cardiac muscle, and it is easily blocked that the puncture needle head end does not have side opening, influence the positive rate of collect specimen chemical examination, puncture needle non-once use tail end sebific duct can be out of shape because of repeatedly sterilizing, and syringe is connected with it and does not closely cause tube chamber airtight poor.
The summary of the invention the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of disposable use can avoid cross infection, cheap, is fit to the disposable paracentesis pericardii pin that hospitals at different levels use.
The technical solution of the utility model is: disposable paracentesis pericardii pin is made up of puncture needle and sleeve pipe, and puncture needle pin wall indicates scale, and the sleeve pipe head end is provided with side opening, casing seat is provided with three-way valve.
This utility model is because puncture needle pin wall indicates scale, and casing seat is provided with three-way valve, and is therefore easy to operate, seal is strong, success rate and An Jin height.
Description of drawings Fig. 1 is this utility model structural representation
Specific embodiment this utility model is made up of puncture needle (1) and sleeve pipe (4) two parts, puncture needle (1) outer surface and sleeve pipe (4) inner surface tight connecting, both couplings, puncture needle (1) is long than sleeve pipe (4), sleeve pipe (4) head end has puncture needle (1) needle point to run off, sleeve pipe (4) tail end has puncture needle needle stand (8) to run off, puncture needle (1) pin wall indicates scale (3), sleeve pipe (4) is made by having flexible transparent material, respectively be provided with an aperture (2) along sleeve pipe (4) an angle of 90 degrees direction of being separated by on the Different Plane on every side in end points 1.5 cm range of sleeve pipe (4) top, owing to a plurality of apertures (2) are arranged so be difficult for stopping up and institute's collect specimen positive rate height, casing seat (5) is provided with three-way valve (6), and Paracentesis needle holder (8) is connected closely with casing seat (5), and seat plug (9) is arranged in the Paracentesis needle holder (8).During use, the patient holds the pin puncture, because of the pin wall indicates scale (3), can accurately put in place, the back slow pushing sleeve pipe (4) on one side that puts in place, on one side the slow puncture needle (1) of removing, puncture needle (1) is withdrawn from sleeve pipe (4) while turning set base (5) and is gone up three-way valve spool (7), closes this passage, makes it be air-tight state.When casing seat (5) with rotate three-way valve spool (7) again after syringe is connected, open this passage, pericardial cavity, sleeve pipe, syringe are communicated and airtight in order to drawing liquid.
Claims (1)
1. disposable paracentesis pericardii pin, it is characterized in that: form by puncture needle (1) and sleeve pipe (4), the two is complementary, puncture needle (1) pin wall indicates scale (3), sleeve pipe (4) is made by having flexible transparent material, respectively be provided with an aperture (2) along sleeve pipe (4) an angle of 90 degrees direction of being separated by on the varying level on every side in cannula tip end points 1.5 cm range, casing seat (5) is provided with three-way valve (6), turning set base (5) was gone up three-way valve spool (7) when puncture needle (1) was withdrawn from sleeve pipe (4), close this passage, when casing seat (5) with rotate three-way valve spool (7) again after syringe is connected, open this passage.
