Description

Flushing connector for connecting syringe with catheter

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a flushing connector for connecting an injector with a catheter.

Background

Bladder irrigation is a method of using a catheter, injecting a solution into the bladder with a syringe, and draining the injected solution by using a siphon principle. The purpose of the flushing is: 1. for the patient with the indwelling catheter, the urine drainage of the patient is kept smooth. 2. Removing blood clot, mucus, bacteria, etc. in bladder. 3. Treating bladder diseases such as cystitis and bladder tumor. 4. And identifying upper and lower urinary tract infection. Bladder irrigation experiments positively indicated an upper urinary tract infection. However, since the catheter connector is often used to connect catheters, the inner diameter is large, and the nipple of the syringe cannot be directly connected to the catheter connector for flushing due to the small outer diameter.

Disclosure of Invention

The utility model aims to provide a flushing joint for connecting a syringe with a catheter, wherein the joint for the catheter is connected with a nipple of the syringe, so that the bladder flushing is convenient, the connection is simple, and the sealing performance is good.

The technical aim of the utility model is realized by the following technical scheme:

the utility model provides a wash joint for syringe and catheter are connected, includes the stereoplasm connecting pipe, be provided with nipple connection rubber tube in the stereoplasm connecting pipe, the one end of stereoplasm connecting pipe is connected with the rubber hose, the rubber hose include shrink sleeve pipe and with the changeover portion that the stereoplasm connecting pipe is connected, the diameter of changeover portion follows shrink sleeve pipe to the stereoplasm connecting pipe direction diminishes gradually, be provided with many in the rubber hose and be circumference distribution and approximately be the wire of zigzag, every wire all including set up in shrink section in the shrink sleeve pipe, set up in bending section in the changeover portion, set up in connecting section in the stereoplasm connecting pipe, the periphery threaded connection of stereoplasm connecting pipe has screw thread adjustment sleeve pipe, rotates the screw thread adjustment sleeve pipe can extrude bending section and make its crooked.

Through adopting above-mentioned technical scheme, during the use, at first rotate threaded connection sleeve to the rubber hose direction, make the curved section of threaded connection sleeve extrusion wire make it crooked, make the shrink section of wire shrink to the axis direction of rubber hose, drive the rubber hose and warp, make shrink sheathed tube diameter diminish, be convenient for insert in the connector of catheter, insert the back and rotate threaded connection sleeve to keeping away from the rubber hose direction, loosen the curved section of wire, the wire resumes the shape because self elasticity, make shrink sheathed tube diameter resume firmly and prop the inner wall of catheter connector for the leakproofness is better, alright be connected the nipple of syringe with the nipple connection rubber tube in the stereoplasm connecting pipe this moment, alright carry out the washing operation.

The utility model is further provided with: the outer layer of the transition section is peeled off to expose the curved section.

By adopting the technical scheme, the exposed bending section is more beneficial to the movement of the threaded adjusting sleeve to press and bend the threaded adjusting sleeve.

Compared with the prior art, the utility model has the following beneficial effects:

the utility model is used for connecting the joint of the catheter with the nipple of the injector, is convenient for bladder irrigation, and the threaded connecting sleeve is rotated to extrude the zigzag metal wire, so that the metal wire is bent to drive the opening diameter of the rubber hose to be reduced, the rubber hose can be easily inserted into the joint of the catheter, and after the metal wire is loosened, the rubber hose is restored to a shape to tightly support the inner wall of the joint of the catheter, thereby having good sealing wind effect and being not easy to loosen.

Drawings

FIG. 1 is a schematic view of the overall structure of the present utility model;

fig. 2 is used to show the internal structure of the present utility model.

In the figure: 1. a hard connecting pipe; 2. the nipple is connected with a rubber tube; 3. a rubber hose; 31. shrink sleeve; 32. a transition section; 4. a wire; 41. a constriction section; 42. a curved section; 43. a connection section; 5. the threads adjust the sleeve.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

1-2, a flushing joint for connecting a syringe with a catheter comprises a hard connecting pipe 1, wherein a nipple connecting rubber pipe 2 is arranged in the hard connecting pipe 1, the nipple connecting rubber pipe 2 is used for being connected with a nipple of the syringe, sealing performance is better through rubber materials, one end of the hard connecting pipe 1 is connected with a rubber hose 3, the rubber hose 3 comprises a shrink sleeve 31 and a transition section 32 connected with the hard connecting pipe 1, the diameter of the transition section 32 gradually decreases from the shrink sleeve 31 to the hard connecting pipe 1, twelve wires 4 which are distributed circumferentially and approximately in a Z shape are arranged in the rubber hose 3, each wire 4 comprises a shrink section 41 arranged in the shrink sleeve 31, a bending section 42 arranged in the transition section 32, a connecting section 43 arranged in the hard connecting pipe 1, the outer layer of the transition section 32 is peeled off to enable the bending section 42 to be exposed to the outside, a thread adjusting sleeve 5 is connected to the outer circumference of the hard connecting pipe 1 in a threaded mode, and the exposed bending section 42 is further beneficial to moving the bending sleeve 5 to squeeze the bending threads.

The using mode is as follows: when the device is used, the threaded connection sleeve is rotated towards the direction of the rubber hose 3, the threaded connection sleeve is made to extrude the bending section 42 of the metal wire 4 to bend, the shrinkage section 41 of the metal wire 4 is made to shrink towards the axial direction of the rubber hose 3, the rubber hose 3 is driven to deform, the diameter of the shrinkage sleeve 31 is made to be smaller, the device is convenient to be inserted into a connector of a catheter, the threaded connection sleeve is rotated towards the direction far away from the rubber hose 3 after the device is inserted, the bending section 42 of the metal wire 4 is loosened, the metal wire 4 recovers the shape due to elasticity of the device, so that the diameter of the shrinkage sleeve 31 is enabled to recover to firmly support the inner wall of the connector of the catheter, the tightness is better, and at the moment, a nipple of a syringe can be connected with the nipple connecting rubber tube 2 in the hard connecting tube 1, and flushing operation can be carried out.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
