Examples

As shown in figure 1, the novel urethral catheterization device comprises a urethral catheterization bag 1 and a urethral catheter 2, wherein a connector connected with the urethral catheter 2 is arranged on the urethral catheterization bag 1.

In particular, said joint comprises an outermost main joint 3 and an inner adjustable device, the main joint 3 being a hollow cylinder. The adjustable device comprises three connectors 4 which are sleeved on the inner wall of the catheter 2 and three adjusting pieces 5 which are fixed on the inner wall of the main joint 3, wherein the connectors 4 are cylinders which are distributed in an equilateral triangle, and the connectors 4 are movably connected with the adjusting pieces 5 respectively. The adjusting member 5 comprises two opposite elastic adjusting plates 51, a plurality of guide blocks 52 are uniformly arranged on the inner side wall of each transverse adjusting plate 51, the guide blocks 52 are arc-shaped, the distance between each guide block 52 is fixed, and the connecting head 4 can be fixed in the adjusting member 5 through the guide blocks 52 on the two sides of the connecting head, as shown in fig. 2. Medical personnel can make connector 4 can cup joint catheter 2 of different pipe diameters size through the distance between 3 inner walls of adjustable connector 4 and the main joint from outside removal connector 4. Specifically, the medical staff applies force to the inner wall of the main joint 3, so that the connectors 4 can extrude the guide blocks 52 and gradually approach the inner wall of the main joint 3, and after the distance is set, the connectors 4 are clamped between the guide blocks 52, so that the area formed by the three connectors 4 can be enlarged, as shown in fig. 2 (a); the connectors 4 can be pulled out from the adjusting member 5 by applying force to the center of the main joint 3, so as to reduce the area formed by the three connectors 4, as shown in fig. 2 (b). Further, each guide block 52 is also marked with a scale, so that the medical staff can accurately adjust the distance between the connectors 4 according to the specification of the catheter 2. The adjusting part 5, the main joint 3 and the connector 4 are all made of medical plastics, the specific material is thermoplastic polyurethane, and the guide block 52 is an elastic medical rubber support.

Further, in order to realize the tightness between the catheter 2 and the main joint 3, an inflation bag 6 is further arranged on the inner wall of the main joint 3, the inflation bag 6 is located above the connector 4, and an inflation port 9 is arranged on the wall of the inflation bag 6, as shown in fig. 3. After the catheter 2 and the connector 4 are sleeved, medical staff can inject media into the inflatable bag 6 through the injector, so that the inflatable bag 6 is inflated, and after the inflatable bag 6 is in contact with the outer wall of the catheter 2 and part of the inflatable bag is extruded, the injection can be stopped. Since it is considered that the air bag 6 is ruptured in the course of catheterization due to external causes, the escaping gas causes a change in the air pressure in the urinary catheter bag 1, causing a backflow of urine. Therefore, the medium injected in the inflatable bag 6 of the utility model is normal saline, and even if the inflatable bag 6 breaks, the overflowing normal saline can not influence normal catheterization. The inflatable bag 6 is made of medical rubber, the connection mode of the inflatable bag and the inflation port 9 is similar to that of the traditional medical air bag, and the structure is not the improvement point of the application, so the specific structure is not repeated.

Further, because the existence of catheter 2, uncomfortable feeling can appear in patient, when patient stirs or struggles, can cause the extrusion to soft catheter 2 to influence the catheterization process and can cause the screens even and influence medical personnel and extract catheter 2, then again will make patient bear discomfort and painful feeling when drawing the pipe. Therefore, the utility model is also provided with a fastening device on the catheter 2. In particular, the fastening device comprises a fixing band 7 and a fixing tube 8 integrally formed with the fixing band, the fixing tube 8 is hollow and is used for wrapping the catheter 2, and the deformation of the catheter 2 caused by the squeezing of a patient can be avoided through the hard fixing tube 8. The fixed band 7 is two pairs, sets up respectively in the left and right sides of fixed pipe 8, and every end to fixed band 7 is equipped with the magic subsides of mutually supporting, and fixed band 7 is used for tying up in patient's thigh department to the condition that the slip drops appears in fixed pipe 8 on catheter 2 can be avoided to the position of fixed pipe 8. Specifically, during catheterization, a medical worker passes the catheter 2 fixed with the catheterization package 1 through the fixing tube 8, and after the catheterization is finished, the two pairs of fixing bands 7 are respectively fixed at the root of the thigh of a patient in an annular manner, so that the fixing tube 8 is prevented from shifting. The fixing tube 8 is made of medical hard rubber such as silicon rubber, and the fixing band 7 is made of medical woven tape.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
