Abstract
The utility model relates to an auto-ascites ultrafiltration concentration reinfusion puncture needle, the puncture needle is arranged at one end of a drainage tube, and two branch tubes are arrangedat the other end; the puncture needle is a hollow needle body, a partition is arranged in the puncture needle for forming two channels in the hollow needle body, small round holes are respectively distributed on two sides of a needlepoint, and the small round holes are respectively communicated with the corresponding channel; the drainage tube is a dual-channel structure, and the two channels arerespectively communicated with the corresponding channel of the puncture needle and the corresponding branch tube. The auto-ascites ultrafiltration concentration reinfusion puncture needle can overcome the deficiencies that the auto-ascites reinfusion of a large number of clinical patients with ascites needs the secondary local anaesthesia and the secondary abdominocentesis, a needle head is not easy to fix and the like. Compared with the prior art, the auto-ascites ultrafiltration concentration reinfusion puncture needle has the advantages of convenient operation, easy fixation of the needlehead and easy control of the puncture depth, and can reduce the workload of medial staff, complete the auto-ascites ultrafiltration concentration reinfusion by only one time of abdominocentesis and alleviate the suffering of patients.
Description
Technical field
This utility model relates to a kind of medical apparatus that a large amount of ascites patients carry out the puncture use of ascites ultra concentration that is used for.
Background technology
A large amount of clinically ascites patient respiration difficulties can not be put down for sleeping inly, have a strong impact on quality of life.Therapeutic Method is that medicine adds from the body ascites back transfusion, the method of ascites back transfusion mainly is that ascites is through blood dialysis machine ultrafiltration and concentration at present, lose moisture content, keep albumen and nutrient substance, import patient's intraperitoneal again, its method is with dialysing 2 of special-purpose puncture needles for No. 16, thrust the patient abdominal cavity, puncture successfully after, bloody path pipeline one end is connected with 2 puncture needles respectively, the bloody path pipeline other end is connected with dialyser, the outer ascites peripheral passage of organizator.But there is shortcoming in said method: (1) stomach wall plumpness or stomach wall edema patient then puncture needle are short, and puncture is difficult for successfully.(2) the special-purpose puncture needle of dialysis is difficult for fixing after entering the abdominal cavity, and it is fixing to need the special messenger to help, and this brings difficulty to long-time operation.(3) patient needs the secondary local anaesthesia, and the secondary abdominal paracentesis increases patient's misery.
Summary of the invention
The purpose of this utility model be to provide a kind of be used for to patient carry out ascites ultra-filtration concentrate that feed back, easy to operate and syringe needle is easy to fix, patient's misery less, paracentesis depth easily concentrating of control from the body ascites ultra-filtration feed back puncture needle.
For achieving the above object, the technical solution of the utility model is: drainage tube one end has puncture needle, and the other end is two arms; Puncture needle is a hollow needle body, and a partition is arranged in puncture needle, makes to form the dual pathways in the hollow needle body, and the needle point both sides respectively are furnished with small sircle hole, and this small sircle hole is connected with its respective channel; Drainage tube is a channel structure, and its dual pathways is connected with the respective channel of puncture needle and corresponding arm respectively.
Puncture needle needle point both sides respectively are furnished with the small sircle hole of three internal diameter 0.1cm.
Be with the screw holder on the puncture needle, screw holder mesopore is the taenidium structure.
Be equipped with respectively on two arms of the said drainage tube other end and turn-off card.
Two arm ends of the said drainage tube other end have the taenidium that is connected with the blood vessel spiral outward.
The characteristics that this utility model uses: (1) puncture needle is stainless steel, and is sharp keen, is easy to the inserting needle puncture, reduces patient's misery.(2) the screw fixed device is easy to fixedly depth of needle, and the both wings of screw fixed device are convenient to be fixed on the stomach wall; Be convenient to hold the inserting needle operation.(3) channel structure of the present utility model has reduced puncture time, has improved puncture success rate, reduces patient's pain.(4) two of drainage tube manifold configuration do not change original shape of blood vessel and function.(5) reduced the operation number, reduced workload, single can the operation.(6) turn-off card and make more convenient operation.
Compared with prior art, this utility model is easy to operate, and syringe needle is easy to fix, and paracentesis depth is controlled easily, has reduced medical personnel's workload, only needs an abdominal paracentesis can finish from the body ascites ultra-filtration and concentrates feedback, has alleviated patient's misery.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing further describes this utility model.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
In the accompanying drawing, 1 is puncture needle, is about 4.5cm, internal diameter 0.3cm is a hollow needle body, has a partition that it is on average separated from the centre in puncture needle 1, make and form the dual pathways in the hollow needle body, the pinpoint inclined plane opening is sharp keen, is stainless steel, and wall is thin, the upwards about 0.5cm at interval in needle point both sides, three internal diameter 0.1cm small sircle holes are respectively arranged, and small sircle hole is connected with the piercing needle dual pathways respectively, is convenient to the ascites turnover.2 is the screw holder, is enclosed within on the puncture needle, and internal layer is the taenidium structure, spiral activity on puncture needle up and down, be convenient to the fixing inserting needle depth of grasping, both sides are wide for 0.6cm, are about the 2.5cm flank, be the duroplasts material, the both wings external application is applied ointment or plaster during use, is convenient to be fixed on the skin; Be easy to during puncture hold firmly.3 is drainage tube, for the soft silica gel material, is about 30cm, internal diameter 0.5cm, and interior is the dual pathways, and drainage tube 3 one ends have puncture needle 1, and the other end is to be used for two arms (arm 4, arm 5) of being connected with the bloody path pipeline; Arm 4, arm 5 are connected with two dual pathwayss of drainage tube 3 respectively; Arm 4, arm 5 structures are identical, respectively be about 5cm, internal diameter 0.5cm, end has the hard plastic tube of a long 1.5cm, internal diameter 0.5cm, hard plastic tube has taenidium outward, is used for being connected with the blood vessel spiral, need not change the blood vessel shape, the card of shutoff is arranged on two arms 4,5, use when being convenient to drain ascites and turn-offing ascites.
The puncture needle material requires: needle body is a stainless steel, and needle point is sharp keen, is easy to puncture.Drainage tube is the soft silica gel material, and matter is tough, good springiness, easy operating.The screw fixed device is the duroplasts material, is convenient to fix, and is easy to puncture procedure.
