Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a urinary catheter, in particular to an indwelling urinary catheter clamp occluder and the indwelling urinary catheter. Background Art

[0002] Indwelling catheterization is the most common and frequently used nursing operation in the clinic to accurately record urine volume and solve the problem of urination difficulties. Urine bags are essential items for indwelling catheterization and need to be replaced regularly. During indwelling catheterization, the catheter needs to be connected to the urine bag, and the end of the catheter is inserted into the catheter at the top of the urine bag. The two are connected by plugging.

[0003] The utility model patent with application number 202223291177.0 discloses a device for clamping and fixing the connection between the urinary catheter and the urine bag, which includes: a clamping assembly, which includes a clamp body 1, a clamp body 2 and a buckle assembly; the clamp body 1 and the clamp body 2 are used together to clamp the connection between the urinary catheter and the urine bag; the inside of the clamp body 1 and the clamp body 2 forms a receiving groove for the connection between the urinary catheter and the urine bag to pass through, and a fixing assembly is arranged inside. The fixing device clamps and fixes the urinary catheter of the urine bag by setting the special clamping assembly; thereby effectively preventing the urinary catheter from being detached from the port of the urine bag.

[0004] The utility model with application number 202220227627.0 also discloses a urinary catheter clamping device, which includes a urinary catheter, which is used to establish a drainage channel so that the patient's urine can be discharged into a urine bag through the drainage channel. An openable and closable joint is provided on the urinary catheter, and the joint is used to close and / or open the drainage channel to prevent the urine in the urinary catheter from flowing in the drainage channel when the urine bag is replaced, causing the urine to drip into the external environment. By utilizing the switchable function of the joint, the operator can close the urinary catheter before replacing the urine bag, and after connecting a new urine bag, open the joint again to allow the urine in the urinary catheter to flow into the drainage bag. As a result, the operator who replaces the urine bag does not need to lay an absorbent pad or perform other operations, thereby improving the replacement efficiency of the urine bag as a whole. Compared with the traditional urinary catheter, the connector is arranged on the drainage cavity of the urinary catheter, and the connector is used to connect the urinary catheter and the urine bag, and the connector is a switchable connector. When replacing the urine bag, the connector is first closed, and the urine bag is separated from the connector to prevent the urine in the urinary catheter from dripping when the urine bag is replaced, thereby preventing the urine from polluting the surrounding environment. Furthermore, while the connector is used to prevent the urine from dripping, the connecting piece is arranged on the connector, and the connecting piece is used to connect the connector to the urinary catheter, so that the end of the connector connected to the urine bag is facing upward, so that even if the connector is not closed, the urine in the urinary catheter can be prevented from flowing out.

[0005] The utility model patent with application number 202121405466.1 discloses an automatic clamping and releasing device for a urinary catheter, comprising a squeezing clamp body and a urinary catheter, a urinary catheter being installed on the right side of the squeezing clamp body, the squeezing clamp body comprising a pressing sheet assembly, a driving assembly and a pin, the driving assembly being installed on the right side of the base surface of the pressing sheet assembly, a pin being installed at the middle of the bottom of the squeezing clamp body, the pressing sheet assembly comprising an upper pressing sheet and a lower pressing sheet, a lower pressing sheet being installed on the lower side of the upper pressing sheet, a rotating shaft being installed at the connection between the upper pressing sheet and the lower pressing sheet, and the upper pressing sheet and the lower pressing sheet being rotatably connected by the rotating shaft, the driving assembly comprising an external protective box and a lithium-ion battery, a lithium-ion battery being installed on the left side inside the external protective box, and a driving motor being installed inside the external protective box and on the right side of the lithium-ion battery. The overall structure is simple, easy to use, and has high stability and practicality.

[0006] The above provides catheters with various clamping structures, but in actual applications, most catheters still use a structure such as the utility model patent with application number 202121405466.1, that is, the catheter is clamped or loosened by a squeezing clamp to achieve connection and blocking of the catheter. However, the connection and blocking of the catheter are achieved by clamping or loosening with a clamp or other structure. On the one hand, since the clamp is detachably clamped on the catheter, it is very easy to be touched, collided, or dropped during the movement of the patient or medical staff, and the catheter cannot be effectively blocked. On the other hand, since the action area of ​​the clamp and the catheter is small when the clamp is clamped, the catheter is partially deformed by the clamp after the connection of the catheter is blocked, and some areas of the inner wall of the catheter are fitted. After the clamp is released, the catheter needs a long time to recover the deformation, and the catheterization efficiency is low. In addition, since the contact area between the clamp and the catheter is small, the local deformation makes the inner wall of the catheter fit, and the catheter is easily damaged by the clamp, affecting the normal use of the catheter. Utility Model Content

[0007] The utility model aims to provide an indwelling urinary catheter clamp and an indwelling urinary catheter in order to solve the technical problems that the existing clamp-type urinary catheter is easy to fall off and the urinary catheter has a long time to recover its deformation, resulting in low urinary catheter efficiency.

[0008] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0009] An indwelling urinary catheter clamp occluder comprises a first tube body, a second tube body and a third tube body which are arranged in sequence, and the second tube body can rotate on the first tube body and the third tube body around the axis of the second tube body;

[0010] The first tube body, the second tube body and the third tube body are respectively provided with a first catheter hole, a second catheter hole and a third catheter hole for catheterization. The aperture of the first catheter hole decreases in a direction approaching the second catheter hole, and the shape gradually changes from a round hole to a non-round hole. The aperture of the third catheter hole decreases in a direction away from the second catheter hole, and the shape gradually changes from a rectangular hole to a non-round hole.

[0011] Furthermore, a connecting inner sleeve is provided at the end of the first tube body close to the second tube body, and ratchets are evenly distributed on the outer cylindrical surface of the end of the connecting inner sleeve along the circumference of the first tube body; a connecting outer sleeve is provided at the end of the second tube body, and a pawl is hinged at the position of the connecting outer sleeve corresponding to the ratchet, and the pawl is clamped in the ratchet.

[0012] Furthermore, the connecting inner sleeve of the first tube body is arranged as a stepped shaft, the small diameter section on the outside of the stepped shaft is a ratchet, the large diameter section on the inside is arranged with an external thread, the large diameter section is threadedly connected with a connecting nut, and end face bearings are arranged between the side surface of the nut and the inner boss at the end of the second tube body, and between the inner boss at the end of the second tube body and the side surface of the first tube body or the third tube body, and the inner boss at the end of the second tube body is pressed against the first tube body or the third tube body through the connecting nut.

[0013] Furthermore, the shapes of the first urinary catheter hole and the third urinary catheter hole transition from a round hole to a rectangle, and the long side of the rectangle is smaller than the diameter of the round hole.

[0014] Furthermore, the shapes of the first urinary catheter hole and the third urinary catheter hole transition from a circular hole to an ellipse, and the major axis of the ellipse is smaller than the diameter of the circular hole.

[0015] An indwelling urinary catheter comprises a urinary catheter; the urinary catheter is provided with the above-mentioned indwelling urinary catheter clamp occluder.

[0016] The beneficial effects of the utility model are as follows:

[0017] In the utility model, the entire indwelling urinary catheter clamp occluder is composed of three tubes, and the second tube located in the middle can rotate; because the apertures of the first and third urinary catheter holes are gradually reduced in the direction close to the second tube; therefore, during the rotation of the second tube, the urinary catheter will be gradually twisted, causing the inner walls of part of the urinary catheter to overlap (or fit), blocking the front and back communication of the urinary catheter; when the second tube is rotated in the reverse direction, the twisted state of the urinary catheter is relieved, the inner walls of the originally overlapped (or fitted) urinary catheter will be separated again, and the front and back of the urinary catheter will be connected again; therefore, the urinary catheter can be closed and connected by rotating the indwelling urinary catheter clamp occluder in the forward and reverse directions, and the entire indwelling urinary catheter clamp occluder is sleeved outside the urinary catheter, and there will be no problem of falling off the urinary catheter, and the opening and closing conversion of the urinary catheter is more convenient, efficient and quick.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] Therefore, based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present utility model.

[0030] Example 1

[0031] The present embodiment provides an indwelling urinary catheter clamp, which includes a first tube body 11, a second tube body 12 and a third tube body 13 arranged in sequence, the first tube body 11, the second tube body 12 and the third tube body 13 are coaxially arranged, and the second tube body 12 can rotate on the first tube body 11 and the third tube body 13 around the axis of the second tube body 12.

[0032] The first tube body 11, the second tube body 12 and the third tube body 13 are respectively provided with a first urinary guide hole 14, a second urinary guide hole 15 and a third urinary guide hole 16 along their axial direction, and the urinary catheter 2 can pass through the first urinary guide hole 14, the second urinary guide hole 15 and the third urinary guide hole 16 in sequence. The aperture of the first urinary guide hole 14 decreases in sequence along the direction close to the second urinary guide hole 15, and the shape of the first urinary guide hole 14 gradually transitions from a circular hole to a non-circular hole along the direction close to the second urinary guide hole 15, and the size of the non-circular hole is smaller than the size of the circular hole. The aperture of the third urinary guide hole 16 decreases in sequence along the direction close to the second urinary guide hole 15, and the shape of the third urinary guide hole 16 gradually transitions from a circular hole to a non-circular hole along the direction close to the second urinary guide hole 15, and the size of the non-circular hole is smaller than the size of the circular hole. The aperture of the second urinary guide hole 15 remains unchanged along the length direction of the second urinary guide hole 15, and the aperture and shape of the two ends of the second urinary guide hole 15 are consistent with the end of the first urinary guide hole 14 and the front end of the third urinary guide hole 16.

[0033] Before use, the urinary catheter 2 is passed through the first urinary catheter hole 14, the second urinary catheter hole 15, and the third urinary catheter hole 16 of the indwelling urinary catheter clamp, and the other end of the urinary catheter 2 is connected to the urine storage bag 3, and the urine storage bag 3 can also be connected to auxiliary components such as a urine catheter. During use, since the aperture of the second urinary catheter hole 15 in the second tube body 12 is smaller than the apertures of the front end of the first urinary catheter hole 14 and the rear end of the third urinary catheter hole 16, when the urinary catheter 2 needs to be blocked, the second tube body 12 is rotated, and the second urinary catheter hole 15 is gradually dislocated with the end of the first urinary catheter hole 14 and the front end of the third urinary catheter hole 16. During the process of rotating the second tube body 12, the urinary catheter 2 will gradually twist, causing the inner wall of part of the urinary catheter to overlap (or fit), and the urine in the urinary catheter cannot pass through; when the urinary catheter 2 needs to be connected, the urinary catheter 2 is rotated in the opposite direction, and the second urinary catheter hole 15 is gradually overlapped with the end of the first urinary catheter hole 14 and the front end of the third urinary catheter hole 16. During the process of rotating the second tube body 12, the urinary catheter 2 will gradually return to a hollow state, the urinary catheter is connected front and back, and the urine in the urinary catheter can pass normally.

[0034] Example 2

[0035] On the basis of Example 1, in order to prevent the second tube 12 from automatically resetting during the gradual rotation, a ratchet and pawl mechanism is provided between the first tube 11 and the second tube 12, and / or between the third tube 13 and the second tube 12. That is, a connecting inner sleeve is provided at the end of the first tube 11 close to the second tube 12, and ratchet teeth 112 are evenly distributed on the outer cylindrical surface of the end of the connecting inner sleeve along the circumference of the first tube 11, so that a ratchet is formed at the end of the connecting inner sleeve of the first tube 11. A connecting outer sleeve is provided at the end of the second tube 12, and a ratchet 19 is hinged at the position of the connecting outer sleeve corresponding to the ratchet 112, and the ratchet 19 is clamped on the ratchet 112.

[0036] Similarly, the structure between the third tube body 13 and the second tube body 12 is the same as the structure between the first tube body 11 and the second tube body 12, which will not be repeated here. See the attached drawings for details.

[0037] During use, when it is necessary to block the catheter 2, the second tube body 12 is rotated, and under the action of the ratchet 19, the second tube body 12 will not rotate in the opposite direction by itself; when it is necessary to conduct the catheter 2, the ratchet 19 is pressed down to make the ratchet 19 disengage from the contact with the ratchet teeth 112, and under the action of the twisted catheter 2 or external force, the second tube body 12 rotates in the opposite direction until the second tube body 12 returns to the initial position (that is, the second catheter hole 15 coincides with the end of the first catheter hole 14 and the front end of the third catheter hole 16), the catheter 2 is connected front and back, and urine can flow normally into the urine storage bag 3 for storage.

[0038] Example 3

End bearings are provided between the side of the nut 18 and the inner boss 17 at the end of the second tube body 12, and between the inner boss 17 at the end of the second tube body 12 and the side of the first tube body 11 or / and the third tube body 13. The inner boss 17 at the end of the second tube body 12 is pressed against the first tube body 11 or the third tube body 13 through the connecting nut 18, and under the action of the end bearing, the second tube body 12 can rotate.

[0041] On the basis of Example 1, Example 2 or Example 3, the shapes of the first urinary catheter hole 14 and the third urinary catheter hole 16 are changed from round holes to rectangles, and the long side of the rectangle is smaller than the diameter of the round hole.

[0042] Example 5
