Abstract

The utility model discloses a concentric circle joint used for peritoneal dialysis therapeutic devices, composed of a connecting seat, a plug and an accessory cork. The connecting seat and the plug are sheathed by circle walls with different length and a gap is left; the connecting seat and the plug use a sliding fit and a screw to fasten to connect with the outer tube for the peritoneal dialysis treatment. The utility model can be opened for the disposable treatment and the tube is kept lying outside sterile; the treatment is convenient and the cost of treatment is low.

Description

Concentric circle joint for peritoneal dialysis

This utility model relates to a kind of medical device, specifically is meant a kind of concentric-ring pattern joint that human body peritoneal dialysis treatment connecting pipe is used that is used for.

At present, the doctor is to renal insufficiency, the peritoneal dialysis method is usually adopted in the treatment of person having renal failure, what abroad adopted is that two kinds of plumbing installations carry out peritoneal dialysis perfusion intraperitoneal, and a kind of is " O " type plumbing installation, and another kind is " Y " type plumbing installation, two types pipe joint all need adopt safe town type joint to connect, and safe lock joint can be sterilized by interior sterilization method, do not need iodine tincture, ethanol and gauze, and the incidence rate of treatment posterior peritoneum inflammation is lower.But " O " type, " Y " type device cost an arm and a leg, especially safe lock joint and once about 2200 yuan of cover outer tube need RMB, need every patient's every day of required peritoneal dialysis solution if join again, then cause domestic patient can not bear medical expense, can only be only for a few patients use at home.Domestic production has " B " type joint and the supporting use of outer tube, " B " type joint adopts outer sterilization, need to use iodine tincture, alcohol disinfecting, reuse gauze parcel, employed joint is more when changing peritoneal dialysis solution, easily contaminated, cause the incidence rate of peritonitis higher, make patient be difficult to receive treatment, and also make troubles for the operator.

This utility model purpose is a kind of concentric-ring pattern joint that can match with outer tube and use of design, solves sterilization in the joint, does not need iodine tincture, ethanol, gauze, opens disposable the finishing of treatment, and easy and simple to handle, relatively cheap, good effect can satisfy the patient needs.

The technical scheme that realizes this utility model purpose is that the headstock portion with the concentric-ring pattern joint forms with three circle wall fits, and on intermediary circle wall, keep somewhere external screw thread, being slidingly fitted with the outer tube patch plug that is provided with inside and outside two circle walls is connected again, and promptly forms the peritoneal dialysis treatment device that the concentric-ring pattern joint matches with outer tube.When stopping to treat, peritoneal dialysis outer tube patch plug is transferred to, assigned gag will be retained in Intraabdominal Dialysis tubing again and partly kept.

Below in conjunction with description of drawings this utility model structure is described in detail.

Accompanying drawing 1 is this utility model A portion, B portion side view.

Accompanying drawing 2 is this utility model vertical views.

Accompanying drawing 3 is side views of this utility model gag.

Accompanying drawing 4 is this utility model A portion and the gag user mode side views that join.

With reference to accompanying drawing 1, Fig. 2, concentric-ring pattern joint shown in Figure 3.It is made up of plinth (A) and outer tube patch plug (B) two parts and attached gag (9), and plinth is made of round bottom seat (1), outer circle wall (2), middle circle wall (3), interior circle wall (4), pipe (5).Outer circle wall (2), middle circle wall (3), the thickness of interior circle wall (4) is 1mm, they also are connected as a single entity with round bottom seat (1), outer circle wall (2) length is 5mm, the length of middle circle wall (3) and interior circle wall (4) is 10mm, its both circle wall length equal difference are 5mm, outer circle wall (2) to the spacing of middle circle wall (3) is 1.5mm, middle circle wall (3) to the spacing of interior circle wall (4) is 1mm, the lateral surface of middle circle wall (3) leaves oblique external screw thread, the formed tube chamber of interior circle wall (4) communicates with pipe (5), outer circle wall (2), middle circle wall (3), interior circle wall (4) three is a central point concentric circular each other with pipe (5) all, and keep the spacing fit, form concentric-ring pattern plinth (A) partly.According to the outer tube patch plug (B) of concentric-ring pattern joint shown in the accompanying drawing 1 partly, it is by connector base (6) and outer circle (7), interior circle (8) formation.Inside and outside circle (8), (7) all are connected as a single entity with connector base (6), the high 15mm of wall of outer circle (7), and thick 1.5mm, the casting of wall medial surface leaves oblique female thread, and its screw thread matches with the external screw thread of outer wall circle (2).The high 12mm of interior circle (8) wall, thick 1mm, its wall bottom thickens and is connected as a single entity with connector base (6), interior circle (8) bore 3mm, tube chamber communicates with the tube chamber and the pipe (5) of base (6).Outer circle (7) is 3mm with the spacing of interior circle (8).According to the gag (9) shown in the accompanying drawing 3, it is the plug that assigns into the plinth end, be cylindrical at the bottom of the lid of gag (9), one side of bottom surface leave equal in length in, outer two circle walls (10), (11), its length is 10mm, the wall thickness 1mm of outer circle (11), the wall medial surface leaves oblique female thread, match with the oblique external screw thread in middle circle (3) the wall outside, the wall thickness 1mm of interior circle (10), with slippery the closing of circle internal clearance of plinth, the central part of lid bottom surface is a high 3mm, diameter is the cone (12) of 5mm, is used to stop up the tube chamber of pipe (5).

Structural principle of the present utility model and using method are that whole joint adopts the mutual fit of concentric structure, and keep the distance of each circle between wall, utilize being slidingly matched and the fastening effect of turn-knob of screw thread of plinth interfix, make the outer pipe unit of peritoneal dialysis treatment connect and separate, product is better than abroad " O ", " Y " type peritoneal dialysis unit.

The utility model has the advantages that: 1. the geometrical property of concentric circle joint utilization circle, it is good to patch the rear airtight performance that is slidingly matched, and is applicable to that peritoneal dialysis unit uses; Compare with external safe lock joint, have more anti-pollutionly, prevent the advantage that peritonitis produces. 2. when using this device, when nondialytic treatment, it is airtight that injection thimerosal in the round gap of concentric circles plinth is inserted gag, and namely sustainable sterilization does not need alcohol, the tincture of iodine, gauze, can keep for a long time peritoneum dialysis catheter to keep somewhere and use. 3. the concentric circle joint simple structure is produced easily, and the inexpensive economy of product is easy and simple to handle, adapts to patient and treats voluntarily use.
