Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urinary catheter traction device. Background Art

[0002] After transurethral prostate surgery, urinary catheter traction is often carried out to prevent bleeding in the prostate surgical area from entering the bladder to form blood clots, and at the same time, it can also produce a hemostatic effect by compressing the bladder neck. Currently, the commonly used methods mainly include the gauze compression method, the adhesive tape sticking method, and the urinary catheter traction rack, but these methods all have certain disadvantages. First of all, in the gauze compression method, if the gauze is wound too loose or too tight, the traction effect is poor, the urinary catheter is compressed, resulting in poor patency of the urinary catheter, and the pain caused by the rough texture of the gauze rubbing is unbearable for the patient. Moreover, after being soaked in liquids such as blood, the gauze knot is extremely difficult to untie. In the adhesive tape sticking method, as the patient moves, the adhesive tape is easy to fall off and the discomfort at the sticking position is relatively strong. The urinary catheter traction rack further restricts the patient's movement and the patient feels more uncomfortable. Content of the Utility Model

[0019] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The urinary catheter traction device according to an embodiment of the present invention, as Figures 1 to 4As shown in the figure, the urinary catheter traction device includes a housing 1, a restraint member 2, and a locking member 4. The restraint member 2 is located inside the housing 1. The housing 1 includes a first piece and a second piece, and the first piece and the second piece are hinged. The locking member 4 is respectively connected to the first piece and the second piece to enclose the first piece and the second piece to form a cylindrical space. The restraint member 2 is located inside the cylindrical space. The restraint member 2 includes a first section 21 and a second section 22. The urinary catheter sequentially passes through the first section 21 and the second section 22. The first section 21 is connected to the second section 22. A tube groove 211 is provided in the center of the first section 21 to restrain the urinary catheter, and a filler 221 is provided in the second section 22 to absorb blood and secretions. The housing 1 is formed by splicing the first piece and the second piece into a cylindrical pipe fitting. The first piece and the second piece can be hinged together through a rotating shaft, which is convenient for the user to operate with one hand. The locking member 4 is arranged on the opposite side edges of the first piece and the second piece. The locking member 4 is used to fix the first piece and the second piece together to ensure the fixation of the housing 1. The restraint member 2 is located inside the housing 1 to restrain the urinary catheter, which can avoid problems such as unsmooth pipeline caused by gauze pressing on the urinary catheter, discomfort caused by adhesive tape sticking to the urinary catheter, and easy detachment. The tube groove 211 provided in the first section 21 of the restraint member 2 restricts the urinary catheter in the groove, which can avoid large-scale movement of the urinary catheter and ensure the restraint effect. The second section is provided with a filler 221 to absorb blood and secretions flowing out of the urethral orifice, which can avoid discomfort caused by blood and secretions and the problem that it is difficult to remove after the soaked gauze dries. Different models of the first section 21 can be designed and produced according to the outer diameters of different specifications of the urinary catheter. The sizes of the tube grooves 211 of different models of the first section 21 are different to achieve the restraint effect on the urinary catheter. The housing 1 can be made of hard plastic to play a role in protecting and fixing the internal restraint member 2.

[0021] The urinary catheter traction device according to the embodiment of the present invention has the advantages of good urinary catheter traction and fixation effect, less restriction on the activities of patients, more comfortable body feeling of patients, and easier loading and unloading.

[0022] In some embodiments, the length ratio of the first section 21 to the second section 22 is 4:3.

[0023] Specifically, the first section 21 being longer than the second section 22 can better restrain the urinary catheter. The urinary catheter is mainly restrained by the first section 21, and the second section 22 is used to absorb blood and secretions to reduce the risk of infection.

[0024] In some embodiments, as Figure 3 and Figure 4 shown, a plurality of one-way anti-slip strips 3 are provided on the groove wall of the tube groove 211 to increase the static friction force for one-way movement relative to the tube groove 211.

[0025] Specifically, the first section 21 can be split into two halves, with a groove provided on each half. After the two halves are joined together, the tube groove 211 is formed by the joining of the two grooves into a tubular groove. The diameter of the tube groove 211 is slightly smaller than the outer diameter of the catheter, ensuring that there is a relatively large frictional force between it and the catheter without overly compressing the catheter to cause obstruction of urine outflow. It can be understood that the catheter itself has a certain elasticity and undergoes elastic deformation in the tube groove.

[0026] The one-way anti-slip strips 3 increase the static frictional force between the catheter and the tube groove 211, improve the fixing stability of the urinary catheter, and prevent the restraint member 2 from driving the outer shell to slide relative to the catheter in the direction of the outlet end of the catheter. It can be understood that the one-way anti-slip property enables the restraint member 2 to move towards the glans penis end of the subject with a small frictional force, smoothly shortening the distance from the subject's urethral orifice to the water sac of the catheter, so that the water sac of the catheter can better compress the position of the subject's bladder neck. When the urinary catheter traction device moves towards the outlet end of the catheter, the frictional force of the catheter against the one-way anti-slip strips 3 increases, making it difficult to move relative to the restraint member 2.

[0027] In some embodiments, as Figure 3 and Figure 4 shown, the distance between any adjacent one-way anti-slip strips 3 is equal.

[0028] Specifically, the equal-spacing distribution of the one-way anti-slip strips 3 is beneficial for providing uniform frictional resistance to prevent the urinary catheter traction device from slipping in the opposite direction, i.e., the direction of the outlet end of the catheter, after being fixed in position.

[0029] In some embodiments, as Figure 3 and Figure 4 shown, the one-way anti-slip strips 3 are bent away from the second section 22.

[0030] Specifically, the one-way anti-slip strips 3 are bent away from the second section 22, and multiple one-way anti-slip strips 3 form a wavy array or a bent linear array. When the catheter moves away from the second section 22, it is blocked by the one-way anti-slip strips 3.

[0031] In some embodiments, as Figure 4 shown, the one-way anti-slip strips 3 are arranged in a staggered manner with any adjacent one-way anti-slip strips 3, and the width between the one-way anti-slip strip 3 and the adjacent one-way anti-slip strip 3 gradually decreases in the direction away from the second section 22.

[0032] Specifically, the one-way anti-slip strips 3 are staggered with the adjacent one-way anti-slip strips 3. One one-way anti-slip strip 3 is parallel to another one-way anti-slip strip 3 with one one-way anti-slip strip 3 in between. The extension directions of two adjacent one-way anti-slip strips 3 intersect, and the intersection point is located on the side of the one-way anti-slip strip 3 away from the second section 22. The staggered arrangement of the one-way anti-slip strips 3 can increase the coverage range of the one-way anti-slip strips 3

[0033] In some embodiments, the length of the filler 221 is greater than the length of the second section 22, and the ratio of the length of the filler 221 to the length of the second section 22 is 4:3.

[0034] Specifically, the length of the filler 221 is greater than the length of the second section 22, so that a part of the filler 221 extends beyond the restraint 2, ensuring that the filler 221 protrudes from the outer shell 1 after closing. On the one hand, the filler 221 can absorb the blood and secretions flowing out of the urethral orifice, and on the other hand, it can protect the glans penis to reduce the discomfort of the subject.

[0035] In some embodiments, the first section 21 is made of rubber material, and the second section 22 is made of absorbent sponge.

[0036] Specifically, the absorbent sponge provides sufficient absorption capacity to keep the environment around the urinary catheter dry and clean, reduce the discomfort of the glans penis suffering from foreign body friction, and improve the comfort of the patient. The rubber provides good support effect, and there is also a large static friction force between the rubber and the outer shell 1.

[0037] In some embodiments, the second section includes two semi-cylindrical absorbent sponges.

[0038] Specifically, the two semi-cylindrical absorbent sponges provide a larger contact area and absorption capacity, better protect the glans penis, and reduce friction and discomfort.

[0039] In some embodiments, the locking member 4 includes two connecting blocks. A slot is provided on one connecting block, and a plug is provided on the other connecting block. The plug is inserted into the slot and fixed, and the connecting block is rotatably connected to the outer shell. Alternatively, the locking member 4 includes two magnetic blocks with different magnetic polarities. The two magnetic blocks are respectively arranged on the first piece and the second piece of the outer shell. After the first piece approaches the second piece, the two magnetic blocks attract each other magnetically to complete the fixation of the outer shell.

[0040] Example 1: The outer shell 1 is a cylinder with a length of 7 cm and a diameter of 4 cm. A foldable plastic is provided between the first piece and the second piece of the outer shell 1 to ensure the formation of a closed outer shell 1 and prevent the absorbent sponge of the second section 22 from leaking outwards. The first section 21 is made of rubber material with a length of 4 cm. The absorbent sponge of the second section 22 has a length of at least 3 cm, which can be 4 cm. The absorbent sponge protrudes 1 cm from the outer shell 1 to contact the glans penis of the subject to provide protection and reduce the discomfort of the subject.
