Description

Tube head sleeve of central venous tube

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a tube head sleeve of a central venous tube.

Background

Patients with kidney diseases such as uremia need hemodialysis during treatment. Before hemodialysis, a central venous access catheterization procedure is required to connect one end of a central venous tube to the central vein of a patient. Referring to fig. 1, the other end of the central venous line 4 is provided with a valve 43, which valve 43 leads out two branch lines 41 for introducing the patient's blood into the dialysis apparatus and for introducing the dialyzed blood into the patient, respectively.

The free ends of the two branch pipes 41 are provided with pipe heads 42 used for being connected with dialysis equipment, after the hemodialysis operation is completed, the pipe heads 42 are disinfected, then the pipe heads 42 are sealed, finally the pipe heads 42 are wrapped by gauze, the pipe heads are adhered to a patient by adhesive tapes and fixed, and the pipe heads are prevented from shaking along with the movement of the patient and being polluted. However, such an operation method also has the following problems: the time for wrapping the tube head is long, and the time and the labor are wasted.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention aims to provide a tube head sleeve which is convenient for covering the tube head of the central venous tube and can keep the tube head clean and breathable.

The technical scheme adopted by the utility model for solving the technical problem is as follows:

the utility model provides a tube head cover of central venous line, includes stereoplasm sleeve, ventilative dust bag and soft sleeve, the telescopic preceding tip of stereoplasm inserts the sack and the stereoplasm sleeve of ventilative dust bag and ventilative dust bag fixed connection, the telescopic back tip of stereoplasm inserts soft sleeve's preceding port and stereoplasm sleeve and soft sleeve fixed connection, be provided with on the soft sleeve and tighten its binding device on the valve of central venous line.

Preferably, the soft sleeve and the air-permeable dust-proof bag are both bonded to the hard sleeve.

Preferably, the soft sleeve and the air-permeable dust-proof bag are made of non-woven fabrics.

Preferably, the tightening means comprises a rubber band disposed at the rear port of the flexible sleeve.

Preferably, the circumference of the rubber band when stretched is larger than the outer circumference of the rear end of the hard sleeve, and a limit boss is arranged in the middle of the outer side wall of the hard sleeve.

Preferably, the inner hole of the hard sleeve is oval in cross section.

The utility model has the beneficial effects that: the tube head penetrates through the soft sleeve and the hard sleeve and is sleeved in the breathable dustproof bag, and the tightening device on the soft sleeve is tightened on the valve of the central venous tube, so that the tube head can be sleeved by the tube head, the dustproof and breathable effects are realized, the cleanness of the tube head is kept, and the operation is very convenient.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly. In addition, the descriptions related to "preferred", "less preferred", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "preferred" or "less preferred" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 3, an embodiment of the present invention provides a tubing head sleeve of a central venous catheter, comprising a rigid sleeve 1, an air-permeable dust-proof bag 2, and a soft sleeve 3, wherein the front end of the rigid sleeve 1 is inserted into the mouth of the air-permeable dust-proof bag 2, the rigid sleeve 1 is fixedly connected with the air-permeable dust-proof bag 2, the rear end of the rigid sleeve 1 is inserted into the front end of the soft sleeve 3, the rigid sleeve 1 is fixedly connected with the soft sleeve 3, and the soft sleeve 3 is provided with a tightening device capable of tightening the valve 43 of the central venous catheter 4.

After the hemodialysis operation is completed, the tube head 42 is disinfected firstly, then the tube head 42 is sealed, finally the tube head penetrates through the soft sleeve 3 and the hard sleeve 1 and is sleeved in the breathable dust-proof bag 2, and the tightening device on the soft sleeve 3 is tightened on the valve 43 of the central venous tube 4, so that the tube head can be sleeved by the tube head, the dustproof and breathable effects are realized, the cleanness of the tube head is kept, and the operation is very convenient.

In a preferred embodiment of the present invention, the soft sleeve 3 and the air-permeable dust-proof bag 2 are made of non-woven fabric, and the hard sleeve 1 is made of hard plastic such as PVC. The soft sleeve 3 and the breathable dust-proof bag 2 are both bonded with the hard sleeve 1 through adhesives such as hot melt adhesive, alcohol adhesive and the like.

In a preferred version of the utility model, the tightening means comprise a rubber band 6 arranged at the rear end opening of the flexible sleeve 3. The back end of the soft sleeve 3 adopts the sewing mode similar to the cuff, the back end edge of the soft sleeve 3 is firstly rolled into a circle, the rubber band 6 is rolled therein, and then the back end edge of the soft sleeve 3 is sewn, so that the elastic binding-up structure similar to the cuff of the clothes can be formed. The tightening device adopts the structure, when the tube head 42 is sleeved into the ventilating dust-proof bag 2, the rear end of the soft sleeve 3 can be tightened on the valve 43 of the central venous tube 4 under the elastic action of the rubber band 6, thereby being convenient and fast.

Furthermore, the circumference of the rubber band 6 when stretched is larger than the outer circumference of the rear end of the hard sleeve 1, and a limit boss 5 is arranged in the middle of the outer side wall of the hard sleeve 1.
