Description

Sieve type peritoneo-puncture needle and supporting drainage tube thereof

This utility model relates to a kind of clinical diagnosis and therapeutic utensil, belongs to medical domain.Mainly be that external drainage for ascites provides a kind of sieve type peritoneo-puncture needle and supporting drainage tube thereof.

Refractory ascites is the common complication of liver cirrhosis, hepatocarcinoma, abdominal viscera tumor diseases such as (comprising ovary and uterus tumor), brings very big misery to the patient.Solve this difficult problem, generally adopt two kinds of measures, the one, put ascites and add defeated albumin method.Another be the ascites lead body outer after, feed back abdominal cavity or venous measure again.And implement the key of these two kinds of methods, be how ascites to be come out from intraperitoneal drainage smoothly.The external drainage of ascites has two kinds of methods at present: the one, and the peritoneo-puncture needle puncture method, the 2nd, the surgical incision stomach wall is placed thick drainage tube method.But existing peritoneo-puncture needle is that front end perforate, needle body are clumsy, operation the time needs scalpel to cut to cooperate puncture, and wound is big, the postoperative defectives such as ascites that leak outside easily, and the patient is reluctant to accept, and the doctor is reluctant to use.Therefore in fact do not use, and replace with thoracic-puncture needle.But thoracic-puncture needle is thinner, is again single hole, no nook closing member, and drain is stopped up the defective that pin hole interrupts the ascites drain because of omentum majus or other educt often.The surgical incision stomach wall is placed thick drainage tube, though drain is unobstructed, because of traumatic big, sequela is many, and belongs to surgical procedures character eventually, and the patient also is difficult for accepting.Add such patient and stay in internal medicine more, thereby in fact also be difficult to promote.

The purpose of this utility model solves this key difficult problem exactly.By using this novel sieve type peritoneo-puncture needle and supporting drainage tube thereof, it is external that ascites is drained smoothly, thereby carry out various chemical examinations and treatment.Compare with other utensil the utlity model has simple in structure, easy to operate, characteristics such as wound is little, and the patient suffering is little, and is safe, economic, and patient's compliance is good.

The technical scheme that its invention task of finishing this utility model is adopted is: comprise that mainly sieve type peritoneo-puncture needle and supporting drainage tube two large divisions form, sieve type peritoneo-puncture needle also has two parts, comprise that anterior perisporium is the rustless steel needle guard and the rustless steel puncture nook closing member of wire sieve aperture, the front end garden of needle guard is blunt, nook closing member is substantive, front end is sharp, in order to puncture, not only can freely twitch but also not interspace between needle guard and needle guard.Supporting part comprises that coupling, middle part have the elastic drainage tube and the controller of the sacculus that pressurizes, and just constitutes the ideal ascites external drainage of cover system after combining.Puncture needle can make different model according to clinical needs.

Use of the present utility model: unobstructed property and the air-tightness of checking total before using earlier, again nook closing member is inserted in the needle guard, coupling elder generation and drainage tube link, close the controller behind the sacculus, by aseptic requirement routine disinfection site of puncture, after the local anaesthesia success, will have the sieve type peritoneo-puncture needle of nook closing member then, the abdomen method of wearing routinely penetrates the abdominal cavity, extracts nook closing member, sees promptly to connect coupling and drainage tube after having ascites to flow out.The far-end of drainage tube can connect various aspirators (deciding according to purposes), opens gauge tap, and ascites continuously outflows.After achieving the goal, extract puncture needle.

This utility model structural design novelty, scientific and reasonable, the perforate of the forward wire sieve of needle guard type, avoided in omentum majus and the ascites educt to the obstruction of needle tubing, rustless steel nook closing member front end is sharp, makes puncture needle firmer, and it is easier to puncture, and can avoid the stomach wall fatty tissue to enter needle tubing, nook closing member also has the effect of mediation needle guard concurrently simultaneously.If drainage time is than long time, some floating thing stops up the forward sieve aperture of needle guard unavoidably.Can close the controller behind the sacculus this moment, and the extruding sacculus makes increased pressure in the needle tubing, and the ascites refluence washes away the tamper on the sieve aperture, makes sieve aperture unimpeded, and the ascites drain is constantly carried out, and has so just solved the difficult problem that the ascites inadequate drainage often takes place with other method.In addition, when doing ascites back transfusion, sacculus also can play the effect of buffering, water-retention, in order to avoid negative pressure causes drainage wall to subside when excessive.

Embodiment

Accompanying drawing 1 is this utility model structural representation

As shown in the figure: sieve type peritoneo-puncture needle cover (1) is made with rustless steel, and needle guard front end garden blunt (2), the anterior perisporium of needle guard is wire sieve aperture (3), in order to avoid floating thing stops up.Needle guard afterbody (4) is identical with the ordinary syringe afterbody, can connect the standard syringe of various models.Puncture nook closing member (5) is made for rustless steel, and front end is sharp, slightly protrudes in needle guard (1) front end, in order to puncture.Sieve type peritoneo-puncture needle cover (1) and puncture nook closing member (5) are in conjunction with the degree of tightness appropriateness, available rigid plastics of coupling (6) or glass are made, one end more carefully is the frosted shape, overall diameter is identical with the ordinary syringe nipple, join with needle guard afterbody (4), the other end slightly slightly is screw-like, and drainage tube (7) joins, drainage tube (7) and sacculus (8) are an integral body, available rubber or silica gel are made, and sacculus (8) occupies the middle part of drainage tube (7), and the other end of drainage tube (7) and hydrops bottle (10) join, controller (9) occupy on the drainage tube (7) between sacculus (8) and the hydrops bottle (10), and each several part links together and promptly constitutes ideal drainage system.

The concrete use of accompanying drawings: earlier coupling (6) and drainage tube (7) and hydrops bottle (10) are connected before using, closing controller (9) is again in nook closing member (5) the insertion needle guard (1) that punctures.The routine disinfection site of puncture, after the local anaesthesia success, sieve type peritoneo-puncture needle cover (1) method routinely that will have puncture nook closing member (5) penetrates the abdominal cavity, transfer to nook closing member (5), see promptly to connect coupling (6) after having ascites to flow out that open controller (9), ascites promptly continuously outflows, when inadequate drainage, but closing controller (9), extruding sacculus (8) increases intraluminal pressure, ascites flows backwards in the needle tubing, wash away in the needle guard (1) and wire sieve aperture (3) on tamper.When the ascites back transfusion, sacculus (8) then has cushioning effect, can make earlier to hold in the sacculus (8) to have one's mind filled with water, the drainage tube far-end is received on the feedback machine again, opens controller (9), thus the subsiding of the drainage tube that available buffer causes because of negative pressure is excessive (7) wall.Sieve type peritoneo-puncture needle cover (1) stopped up and can remove coupling (6) in real time, and the nook closing member (5) that will puncture inserts in the sieve type peritoneo-puncture needle cover (1) and discloses it, thereby guaranteed that puncture needle is unobstructed, and the ascites drain is continuous.
