Abstract
The utility model discloses a closed chest puncture and drainage tube which comprises a tube body, wherein a drainage branch tube is arranged at the rear end of the tube body; a drainage connector is arranged on the drainage branch tube; side holes are formed in the pipe wall of the front end of the tube body; the front end of the tube body is bent; and a self-closing type puncture connector is arranged at the rear end of the tube body. The closed chest puncture and drainage tube is mainly used for closed chest puncture and drainage, during the use, a trocar integrally performs puncture, a puncture needle is pulled out after reaching a puncture position, and then the drainage tube and the drainage branch tube are connected, so that drainage can be performed. The self-closing type puncture connector automatically seals an insertion hole after the puncture needle pulls away. One-needle type closed chest puncture and drainage can be realized, damage to a patient is small, and the closed chest puncture and drainage tube is simple to operate, safe and minimally invasive.
Description
Technical field
This utility model belongs to chest drainage puncture instrument technical field, specifically relates to an a kind of pin type closed thoracic puncture drainage tube.
Background technology
Clinical treatment tension pneumothorax or hydrothorax, the general method that adopts puncture closed drainage.Conventional method is to carry out, after partly sterilised and anesthesia, first with sharp knife, on the skin that punctures into pin place, doing a kerf, until subcutaneous; With the trocar, from skin incision, slowly thrust through breast chamber; Pull out after nook closing member, then insert rapidly the silica gel tube of front end porous, and then exit sleeve pipe; Silica gel tube is connected to water-sealed drainage bottle; Pin hole place is sewed up, and drainage tube is fixed on thoracic wall.The method of existing puncture drainage, large to patient trauma, troublesome poeration, is used inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of little, simple to operate to patient trauma, closed thoracic puncture drainage tube easy to use.
For solving the problems of the technologies described above, this utility model comprises body, and described body rear end is provided with drain arm, drain arm is provided with flow sub, the tube wall of body front end is provided with side opening, and its construction features is that described body front end is bending, and the follower head of body is provided with self-closing puncture joint.
Preferably described self-closing puncture joint comprises external connection body and the interior junctor being threaded, and on described external connection body and interior junctor, correspondence is provided with puncture channel, is provided with for sealing the self-enclosed film of puncture channel between external connection body and interior junctor.
Further preferably described self-enclosed film is round pie, and its middle part, two sides is cambered surface projection, and self-enclosed film both sides are equipped with support chip, is provided with the circular hole corresponding with described cambered surface projection in the middle of described support chip.
Adopt after said structure, owing to being provided with drain arm and self-closing puncture joint on body, puncture needle inserts body through self-closing puncture joint, and runs through whole body, puncture needle is connected with body, and the sweeping front end of body is vertical under the support of syringe needle.During use, trocar integral body punctures, and arriving site of puncture and extracting after puncture needle, drain arm is connected with drainage tube, can carry out drain.Self-closing punctures joint after puncture needle is deviate from, self-closed jack.Can realize a pin type closed thoracic puncture and drainage, little to patient trauma, simple to operate, safe Wicresoft.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described:
Fig. 1 is this utility model overall schematic;
Fig. 2 is this utility model and puncture needle connection diagram;
Fig. 3 is this utility model self-closing puncture joint cross-sectional schematic;
Fig. 4 is self-enclosed film and support chip schematic diagram in self-closing puncture joint.
The specific embodiment
See figures.1.and.2, this closed thoracic puncture drainage tube comprises silica gel body 1, in body 1 rear end, is provided with drain arm 2, and drain arm 2 is provided with the flow sub 21 that can be connected with drainage tube.On body 1, be provided with along its length length scale sign 5, the degree of depth of inserting needle when this scale can mark puncture.Body 1 front end is pigtail-shaped bending under naturalness.Puncture needle 3 inserts after body 1, and body 1 front end is erectility, and after puncture needle 3 is extracted, the front end natural torsion of body, is conducive to stationary pipes body position.On the tube wall of body 1 front end, be provided with side opening 6, the follower head of body 1 is provided with self-closing puncture joint 4.
With reference to Fig. 3 and Fig. 4, the present embodiment self-closing puncture joint 4 comprises external connection body 41 and the interior junctor 42 being threaded, and interior junctor 42 is threaded with body 1.On external connection body 41 and interior junctor 42, correspondence is provided with puncture channel 45; The puncture channel 45 of external connection body 41 is connected with the needle holder of puncture needle 3.Between external connection body 41 and interior junctor 42, be provided with self-enclosed film 44, this film is used for sealing puncture channel 45.During puncture, puncture needle can penetrate self-enclosed film 44, and after puncture needle is extracted, pinprick is closed, plays sealing process.For reaching good sealing effect, self-enclosed film 44 is round pie, and its middle part, two sides is cambered surface projection, in the both sides of self-enclosed film 44, is equipped with support chip 43, is provided with circular hole in the middle of support chip 43, and this circular hole is corresponding with the cambered surface projection on self-enclosed film 44.If round-meshed support chip 43 self-enclosed film 44 from sandwich, be conducive to the sealing after self-enclosed film 44 is punctured.
