Description

Technical Field

[0001] The present invention relates to the technical field of urinary catheters, and particularly to a male internal urinary catheterization device. Background Art

[0002] For male patients suffering from bladder diseases, the situation of abnormal urination often occurs. The traditional method is to insert a catheter into the patient's body and use the catheter to drain urine into a urine bag for storage. However, inserting and removing the catheter easily causes problems such as bacterial infection.

[0003] Subsequently, a Chinese utility model patent with the authorization announcement number CN210205560U and the authorization announcement date of March 31, 2020 discloses a male internal hidden urinary catheter, which specifically discloses including: a head, a tube portion, and a mechanical control valve located inside the tube; the head is fixed in the bladder cavity, and the head is provided with a urine inlet; the tube portion is placed in the male urethra, and the end of the tube portion is provided with a urine outlet; the mechanical control valve is opened under the action of an external force, urine enters the urinary catheter through the urine inlet, flows out from the urine outlet, and is discharged out of the body through the external urethral orifice. Among them, the control valve is composed of two symmetrically arranged petal-shaped structures that fit tightly, with a hollow interior and usually closed; the bottom of the control valve is connected to two force-applying handles, and the two force-applying handles are respectively fixed to the left and right sides of the inner wall of the tube.

[0004] Placing the male internal hidden urinary catheter in the prior art in the male urethra reduces the risk of bacterial infection. When urinating, the patient finds the position of the handle and presses it. When the handle receives an inward pressure, it can pry the control valve to open the valve and let the urine flow out. However, the control valve of the existing hidden urinary catheter only relies on the tight closure of the two petal-shaped structures and cannot reliably seal the urinary catheter, easily resulting in urine leakage problems. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a male internal urinary catheterization device to solve the problem that the control valve of the existing hidden urinary catheter only relies on the tight closure of the two petal-shaped structures and cannot reliably seal the urinary catheter, easily resulting in urine leakage problems.

[0006] The technical solution of the male internal urinary catheterization device of the present invention is as follows:

[0007] The male internal urinary catheterization device includes an internal sleeve, a sealing structure installed in the internal sleeve, a movable plug body, and a pressing structure. The sealing structure is fixed on the inner wall of the internal sleeve, and the sealing structure has a sealing portion that cooperates with the movable plug body;

[0008] The movable plug body is movably installed in the built-in sleeve along the length direction of the built-in sleeve. The movable plug body has a closed state and an open state. In the closed state, the movable plug body is in sealing cooperation with the sealing part. In the open state, the movable plug body is separated from the sealing part to form a diversion gap.

[0009] The built-in sleeve includes an extrusion deformation part. The extrusion structure is arranged on the extrusion deformation part, and the extrusion structure has a pressing end that moves along the radial direction of the built-in sleeve. The pressing end is used to abut against the movable plug body to move it towards the open state.

[0010] Further, the extrusion structure is installed in the middle of the built-in sleeve. There are two movable plug bodies, and the two movable plug bodies are symmetrically arranged up and down at both ends of the extrusion structure. There are also two sealing structures symmetrically arranged up and down with respect to the extrusion structure.

[0011] Further, a positioning seat is installed in the built-in sleeve. The positioning seat is fixedly connected to the built-in sleeve. The movable plug body is installed on the positioning seat, and an elastic member is connected between the positioning seat and the movable plug body. The elastic member is used to press or tension the movable plug body to move towards the closed state.

[0012] Further, the positioning seat includes a central tube body, a support ring, and connecting ribs. The connecting ribs are arranged between the central tube body and the support ring. There is a diversion channel for urine to flow between the central tube body and the support ring.

[0013] Further, the movable plug body is inserted into the central tube body, and the elastic member is a cylindrical compression spring connected between the movable plug body and the central tube body.

[0014] Further, the movable plug body is a hollow plug sleeve structure, and one end of the movable plug body is provided with a spherical head or a conical head.

[0015] Further, the middle part of the sealing structure is provided with an inner conical flaring. The opening of the inner conical flaring faces the movable plug body, and the inner wall of the inner conical flaring constitutes the sealing part.

[0016] Further, the extrusion structure includes at least two extrusion members. Each extrusion member includes a vertical section and two abutting arms. The vertical section is connected to the extrusion deformation part along the length direction of the built-in sleeve, and the two abutting arms are connected to the vertical section along the radial direction. The end of the abutting arm constitutes the pressing end.

[0017] Further, the extrusion structure further includes an elastic tightening sleeve, and the elastic tightening sleeve is installed between the two extrusion members.

[0018] Further, one end of the built-in sleeve is also connected with a stop sleeve, and the port of the stop sleeve is provided with an outward-turned edge, which is used for concave-convex matching with the front end of the male genital organ.

[0019] Beneficial effects: During use, the male internal urinary catheterization device is inserted into the genital urethra of a male patient. Since the sealing structure, the movable plug body, and the extrusion structure are all arranged inside the built-in sleeve, the outside of the built-in sleeve is smoother and more regular, avoiding damage to the patient's urethra during insertion, and there is no need to frequently insert and remove it after one insertion, with better safety; when there is no extrusion operation, the movable plug body is in a closed state, and the movable plug body is in sealing cooperation with the sealing part of the sealing structure, effectively blocking the urethra to prevent urine from flowing outwards.

[0020] When urination is needed, manually squeeze the corresponding part of the genital organ where the deformed part is located. The deformed part is subjected to the squeezing action and drives the extrusion structure to move radially inwards. The pressing end of the extrusion structure abuts against the movable plug body and moves it towards the open state, so that the movable plug body is adjusted from the closed state to the open state. At this time, the patient's urethral orifice is communicated with the bladder, and the urine in it is discharged by means of the contraction of the bladder muscles, enabling the patient to control urination independently. More importantly, with the overall design of the movable plug body, the sealing structure, and the extrusion structure, and by using the cooperation between the movable plug body and the sealing structure, it can effectively seal the urinary catheterization channel and avoid the problem of urine leakage.

Specific embodiments

[0027] The following will further describe in detail the specific embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0028] Specific embodiment 1 of the male internal urinary catheter device of the present invention is as Figures 1 to 5 shown. The male internal urinary catheter device includes a built-in sleeve 1, a sealing structure 2 installed on the built-in sleeve 1, a movable plug body 3 and an extrusion structure. The sealing structure 2 is fixed on the inner wall of the built-in sleeve 1, and the sealing structure 2 has a sealing portion that cooperates with the movable plug body 3; the movable plug body 3 is movably installed in the built-in sleeve 1 along the length direction of the built-in sleeve 1. The movable plug body 3 has a closed state and an open state. In the closed state, the movable plug body 3 is in sealing cooperation with the sealing portion of the sealing structure 2. In the open state, the movable plug body 3 is separated from the sealing portion of the sealing structure 2 to form a diversion gap; the built-in sleeve 1 includes an extrusion deformation part 10, and the extrusion structure is arranged on the extrusion deformation part 10, and the extrusion structure has a pressing end 420 that moves along the radial direction of the built-in sleeve 1, and the pressing end 420 is used to abut the movable plug body 3 to move towards the open state.

[0029] During use, the male internal urinary catheter device is inserted into the genital urethra of a male patient. Since the sealing structure 2, the movable plug body 3 and the extrusion structure are all arranged inside the built-in sleeve 1, that is, the outside of the built-in sleeve 1 is smoother and more regular, avoiding damage to the patient's urethra during insertion, and there is no need to insert and remove frequently after one insertion, so the safety is better; when there is no extrusion operation, the movable plug body 3 is in the closed state, and the movable plug body 3 is in sealing cooperation with the sealing portion of the sealing structure 2, effectively blocking the urethra to prevent urine from flowing outwards.

[0030] When urination is needed, manually squeeze the part of the genital corresponding to the squeezing and deforming part 10. The squeezing and deforming part 10 is subjected to the squeezing action and drives the squeezing structure to generate a radially inward movement. The pressing end 420 of the squeezing structure abuts against the movable plug body 3 and moves it towards the open state, so that the movable plug body 3 is adjusted from the closed state to the open state. At this time, the patient's urethral orifice is communicated with the bladder, and the urine in it is discharged by means of the contraction of the bladder muscles, enabling the patient to control urination independently. More importantly, with the overall design of the movable plug body 3, the sealing structure 2 and the squeezing structure, and by using the cooperation between the movable plug body 3 and the sealing structure 2, it can effectively seal the urinary catheterization channel and avoid the problem of urine leakage.

[0031] In this embodiment, the squeezing structure is installed in the middle of the built-in sleeve 1. There are two movable plug bodies 3, and the two movable plug bodies 3 are symmetrically arranged up and down at both ends of the squeezing structure. The sealing structure 2 is also provided with two symmetrically up and down with respect to the squeezing structure. By designing the upper and lower groups of movable plug bodies 3 and the sealing structure 2, sealing parts are respectively constructed at both ends of the squeezing structure, improving the actual sealing effect. Moreover, operating the squeezing structure can realize the simultaneous opening of the movable plug bodies 3 at the upper and lower positions.

[0032] Among them, a positioning seat 30 is installed in the built-in sleeve 1. The positioning seat 30 is fixedly connected to the built-in sleeve 1. The movable plug body 3 is installed on the positioning seat 30, and an elastic member is connected between the positioning seat 30 and the movable plug body 3. The elastic member is used to press or pull the movable plug body 3 towards the closed state. Specifically, the movable plug body 3 is a hollow plug sleeve structure, and one end of the movable plug body 3 is provided with a spherical head 32 or a conical head. The positioning seat 30 includes a central tube body 300, a support ring 301 and a connecting rib 302. The connecting rib 302 is arranged between the central tube body 300 and the support ring 301. There is a diversion channel 303 for urine to flow between the central tube body 300 and the support ring 301. The movable plug body 3 is inserted into the central tube body 300, and the elastic member is a cylindrical compression spring 31 connected between the movable plug body 3 and the central tube body 300.

[0033] Install the positioning seat 30 in the built-in sleeve 1. The support ring 301 of the positioning seat 30 is fixedly connected to the built-in sleeve 1. The movable plug body 3 is movably inserted into the central tube body 300, and there is a diversion channel 303 for urine to flow between the central tube body 300 and the support ring 301. The cylindrical compression spring 31 is used to press the movable plug body 3 towards the sealing part, ensuring that when the urinary catheterization device is not squeezed, the movable plug body 3 can automatically reset and remain in the closed state. In other embodiments, in order to meet different usage requirements, the cylindrical compression spring can be replaced with a tension spring connected between the two movable plug bodies 3. Using the tension of the tension spring, the two movable plug bodies can also automatically reset and remain in the closed state.

[0034] In this embodiment, an inner conical flare is provided in the middle of the sealing structure 2. The opening of the inner conical flare faces the movable plug body 3, and the inner wall of the inner conical flare of the sealing structure 2 constitutes the sealing portion. When the movable plug body 3 is in the closed state, the spherical head 32 of the movable plug body 3 is pressed against the inner wall of the inner conical flare of the sealing structure 2. Moreover, the spherical head 32 of the movable plug body 3 protrudes from the end of the sealing structure 2 so that when operating the extrusion structure, its pressing end 420 can radially press against the spherical head 32, causing the movable plug body 3 to move towards the open state and separate from the inner wall of the inner conical flare of the sealing structure 2, achieving the purpose of opening the urinary catheterization channel by extrusion.

[0035] Among them, the extrusion structure includes at least two extrusion members 4. The extrusion member 4 includes a vertical section 41 and two abutting arms 42. The vertical section 41 is connected to the extrusion deformation part 10 along the length direction of the built-in sleeve 1, and the two abutting arms 42 are connected to the vertical section 1 in the radial direction. The end of the abutting arm 42 constitutes the pressing end 420. When the extrusion deformation part 10 is extruded, the extrusion member 4 moves inwards in the radial direction, and the pressing end 420 of the abutting arm 42 is used to press against the spherical head 32, thereby driving the movable plug body 3 to move towards the open state.

[0036] Moreover, the extrusion structure further includes an elastic tensioning sleeve 40, and the elastic tensioning sleeve 40 is installed between at least two extrusion members 4. The elastic tensioning sleeve 40 is used to radially expand the extrusion members 4 outwards to ensure that when there is no extrusion operation, the extrusion members 4 will not form a pressing effect on the movable plug body 3, ensuring the effective sealing fit between the movable plug body 3 and the sealing structure 2. In addition, a stop sleeve 11 is connected to one end of the built-in sleeve 1, and the port of the stop sleeve 11 is provided with an outwardly turned edge 12, and the outwardly turned edge 12 is used to match the front end of the male genitalia in a concave-convex manner. The stop sleeve 11 is provided on the built-in sleeve 1, and the contour shape of the outwardly turned edge 12 adopts a profiling design, which matches the shape of the front end glans of the male genitalia, preventing the entire urinary catheterization device from moving into the urethra and causing discomfort, and can also be smoothly pulled out when replacement is needed.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
