Description

A kind of Medical tee joint joint

Technical field

This utility model relates to a kind of medical conversion connecting device, is specifically related to a kind of Medical tee joint joint.

Background technology

Child's blood purification technology is started late in China, but development in recent years rapidly, the application of child's blood purification technology is more and more extensive, blood purification not only limits to the category removed metabolic waste and maintain water-electrolyte balance, it is to inflammatory mediator, immune complex, the Scavenging activity of toxin, and certain effect is had in stabilised blood hydromechanics, guarantee nutritional supplementation etc.

Child age weight differences is large, differences of Physiological is large, circulation volume is less, required dialysis solution formula multiformity, changes more, is generally adjusted the ion concentration of dosing formula by doctor according to laboratory examination result at any time, so most hospital is when doing in child's blood purification treatment, nurse prepares the required liquid of purification voluntarily at super-clean bench, uses three liters of bags, five liters of bags prepare, and has prepared to connect pipeline of dialysing and treat; Due to the identical consumptive material do not mated with pipe joint, most of hospital adopts direct thrust-type method to carry out the connection of three/five liters of bags and pipeline; Concrete operation is the transfusion device that removal sterilization three/five liters of bags carry, and then folder closing transfusion end, dialysis pipeline tip is thrust transfusion and holds in transparent tube.

Due to the joint do not mated, in actual mechanical process, mainly there is following problem:

1. directly thrust the pollution increasing medicinal liquid, treatment is had an impact;

2. directly thrust because plastic material is comparatively hard, without special entry of stab wound, disposable puncture success rate is low, often needs repeatedly to operate and needs certain puncture experience, otherwise easily damages three liters/five liters bags;

3. directly thrust method, the process of thrusting has partially liq and flows out, and increases the waste of liquid;

4. because joint does not mate, seal is bad, adds that action of gravity when liquid bag hangs can continue leakage over the course for the treatment of, increases the loss of liquid;

5. the mode of straight thrust considerably increases the risk of nurse's pricking wound;

Because therapeutic process continues leakage, fluid loss amount can be caused too much to cause machine alarm to affect normal therapeutic, pollute instrument simultaneously.

Utility model content

The purpose of this utility model is for the problems referred to above, provides the Medical tee joint joint that a kind of convenient for children blood purification liquid line is communicated with; In use can by the joint quick-make of each liquid line.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of Medical tee joint joint, comprises the three-way cock of threeway body and control two or three pipeline connections any, also comprises female thread adapter sleeve, limit baffle ring, rubber blanket, rubber cushion cover and rubber cushion cap, described rubber cap is provided with annular opening; First pipeline of described threeway body is connected with female thread adapter sleeve, and the mouth of pipe of first pipeline extends to the connector outer end of female thread adapter sleeve, second pipeline of described threeway body is provided with external screw thread, on second pipeline that described limit baffle ring is arranged on, the end of the 3rd pipeline of described threeway body is overlapped with rubber cushion and is connected, rubber blanket on rubber cushion cover, and is pressed abd fixed in rubber cushion cover by described rubber cushion cap.

Compared with prior art, the beneficial effects of the utility model are:

Threeway pipeline, on the basis of existing Medical tee joint, is arranged to need syringe needle to puncture the structure that could be communicated with, is avoided universal threaded connect the interface size mismatch problem brought when reality uses by this utility model; And in two other interface of threeway, one of them is female thread type of attachment, wherein another is external screw thread type of attachment, the triplate line having external screw thread type of attachment is provided with limit baffle ring, the operation of three-way cock is had influence on when pipeline can be avoided to connect, the existing female thread of threeway has again external screw thread type of attachment, can conveniently with the connection of general pipeline; This utility model can also combinationally use with the existing threeway having three hickeys, adds the interface type of attachment of three way cock.
