Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and particularly relates to a female self-catheterization assistance device. Background Art

[0002] When urine cannot be discharged smoothly due to certain reasons, "self-catheterization" is one of the means to assist catheterization. "Self-catheterization" is a method of inserting a catheter into the urethra by oneself when urine remains in the bladder. This method does not harm the bladder and has a low risk of causing urinary tract infections, and is evaluated as a very good urination method. It enables urine to be discharged smoothly, avoids a large amount of urine remaining in the bladder, reduces the pressure in the bladder, and protects kidney function.

[0003] "Self-catheterization" is different from the life of always having a catheter inserted and connected to a urine bag. Self-catheterization does not hinder body activities, so one can participate in social activities such as work, school, and travel. Some elderly users with inconvenient lives and novice female users may have difficulties in applying self-catheters, and it is difficult to find the position of the urethral orifice, and the position is prone to deviation when the catheter is inserted into the urethral orifice.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] Aiming at the above problems, the purpose of the present invention is to provide a female self-catheterization assistance device, which solves the problem that the position is prone to deviation when the catheter is inserted into the urethral orifice.

[0006] To achieve the above purpose, the female self-catheterization assistance device provided by the present invention includes an upper component and a lower component connected by a pivot shaft. The upper component includes an upper clamping piece and an upper hand-held piece, and the pivot shaft is located between the upper clamping piece and the upper hand-held piece. The lower component includes a lower clamping piece and a lower hand-held piece, and the pivot shaft is located between the lower clamping piece and the lower hand-held piece. The upper hand-held piece and the lower hand-held piece correspond to each other up and down, and the upper clamping piece and the lower clamping piece correspond to each other up and down;

[0007] It further includes an observation mirror, and the observation mirror is arranged between the upper clamping piece and the upper hand-held piece.

[0008] Preferably, the observation mirror is connected to the side surface or the upper surface between the upper hand-held piece and the upper clamping piece.

[0009] Preferably, an observation mirror mounting seat is provided between the upper hand-held piece and the upper clamping piece, and the observation mirror is connected to the observation mirror mounting seat by a snap connection or a threaded connection.

[0010] Furthermore, an elastic member is provided between the upper hand-held piece and the lower hand-held piece.

[0011] Preferably, the elastic member is a compression spring, and two ends of the compression spring are respectively connected to the upper hand-held piece and the lower hand-held piece.

[0012] Preferably, the elastic member is an elastic sheet, one end of the elastic sheet is connected to the upper hand-held piece, and the other end of the elastic sheet contacts the lower hand-held piece.

[0013] Preferably, a sleeve is sleeved on the outer surface of the upper hand-held piece or the lower hand-held piece, and an arc groove conforming to the finger arc is provided on the sleeve.

[0014] Further, an upper clamping seat is connected to the lower surface of the upper clamping piece, and a lower clamping seat is connected to the upper surface of the lower clamping piece.

[0015] Preferably, an arc groove is provided on the lower surface of the upper clamping seat, and an arc groove with corresponding dimensions is provided on the upper surface of the lower clamping seat at a position corresponding to the arc groove of the upper clamping seat, so that a circular through hole is formed between the upper clamping seat and the lower clamping seat when the upper clamping seat and the lower clamping seat are fitted together for placing a urinary catheter.

[0016] Preferably, the outer surfaces of the upper component and the lower component are wrapped with a silica gel layer.

[0017] The female self-catheterization assistance device provided by the present invention has the following beneficial effects:

[0018] 1. A plurality of circular through holes are formed between the upper clamping seat and the lower clamping seat, and the urinary catheter is placed in the circular through holes, which can avoid pressing on the wall of the urinary catheter; and the upper clamping seat and the lower clamping seat are made of an elastic material, which can not only play an anti-slip role when clamping the urinary catheter, but also increase the clamping force on the urinary catheter by using the elastic force when clamping the urinary catheter, and can avoid pressing on the wall of the urinary catheter to prevent damage to the wall of the urinary catheter by a hard contact surface;

[0019] 2. A sleeve is sleeved on the outer surface of the upper hand-held piece or the lower hand-held piece, and an arc groove conforming to the finger arc is provided on the sleeve, which plays an anti-slip role. After the upper clamping seat and the lower clamping seat clamp the urinary catheter, the sleeve of the upper hand-held piece or the lower hand-held piece can be held alone to insert or remove the urinary catheter from the urethra, which can reduce the effect on the pivot shaft when holding the upper hand-held piece and the lower hand-held piece at the same time, and the upper clamping seat and the lower clamping seat can remain closely fitted to avoid displacement or dropping of the urinary catheter; preferably, the length of the lower hand-held piece is designed to be greater than that of the upper hand-held piece. At this time, a sleeve is sleeved on the outer surface of the lower hand-held piece. Since the lower hand-held piece is the part pinched by four fingers and the upper hand-held piece is the part pinched by the thumb, the pinching area of the lower hand-held piece is larger than that of the upper hand-held piece. Therefore, when the length of the lower hand-held piece is greater than that of the upper hand-held piece, the pinching operation is more comfortable;

[0020] 3. The upper part and the lower part are preferably made of lightweight metal such as titanium alloy or aluminum alloy. Their outer surfaces are smooth, making them easy to clean and disinfect without creating cleaning dead corners. The outer layers of the upper and lower parts can also be wrapped with silicone, which is more corrosion-resistant and has a longer service life.

[0021] 4. An observation mirror is provided between the upper hand-held piece and the upper clamping piece of the upper part. When using the female self-catheterization assistance device to clamp the catheter and insert it into the urethra, the user can observe the positions of the catheter and the urethral orifice through the observation mirror, accurately insert the catheter into the urethral orifice without position deviation.

[0033] To enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the specific embodiments.

[0034] Example 1

[0035] As Figures 1-5 shown, the female self-catheterization assistance device disclosed in this patent includes an upper component and a lower component connected by a pivot shaft 3. The upper component includes an upper clamping piece 1 and an upper hand-held piece 4, and the pivot shaft 3 is located between the upper clamping piece 1 and the upper hand-held piece 4. The lower component includes a lower clamping piece 2 and a lower hand-held piece 5, and the pivot shaft 3 is located between the lower clamping piece 2 and the lower hand-held piece 5. The upper hand-held piece 4 and the lower hand-held piece 5 correspond to each other up and down, and the upper clamping piece 1 and the lower clamping piece 2 correspond to each other up and down. An elastic member 6 is provided between the upper hand-held piece 4 and the lower hand-held piece 5. The elastic member 6 can be an elastic sheet. One end of the elastic sheet is fixedly connected to the upper hand-held piece 4, and the other end of the elastic sheet contacts the lower hand-held piece 5. A detachable upper clamp seat 11 and a detachable lower clamp seat 21 are provided between the upper clamping piece 1 and the lower clamping piece 2. The upper clamp seat 11 is connected to the upper clamping piece 1 and can be connected by one or more bolts. The lower clamp seat 21 is connected to the lower clamping piece 2 and can also be connected by one or more bolts. When not in use, the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 are kept in contact under the action of the pivot shaft 3. The lower surface of the upper clamp seat 11 is provided with a plurality of arc grooves with the same diameter, and the upper surface of the lower clamp seat 21 at the corresponding positions of the arc grooves of the upper clamp seat 11 is also provided with a plurality of arc grooves with corresponding dimensions. When the upper clamp seat 11 and the lower clamp seat 21 are in contact, a plurality of circular through holes are formed between the upper clamp seat 11 and the lower clamp seat 21. The self-catheter is placed in the circular through holes. The inner circumferences of the circular through holes are 8 mm, 10 mm, 12 mm, 14 mm or 16 mm respectively, corresponding to self-catheters with specifications of 8F, 10F, 12F, 14F or 16F respectively. The upper clamp seat 11 and the lower clamp seat 21 are designed to be detachable. The user can select a catheter of one of the specifications according to their own needs, and connect the upper clamp seat 11 and the lower clamp seat 21 corresponding to the catheter of this specification to the upper clamping piece 1 and the lower clamping piece 2 respectively.

[0036] The upper clamp seat 11 and the lower clamp seat 21 are made of elastic materials, and silicone pads or rubber pads can be selected for use. They can not only play an anti-slip role when clamping the catheter, but also increase the clamping force on the catheter by using elastic force when clamping the catheter, and can not cause compression on the catheter wall, preventing damage to the catheter wall by hard contact surfaces.

[0037] The length of the upper hand-holding piece 4 is greater than that of the lower hand-holding piece 5. A sleeve 41 is sleeved outside the upper hand-holding piece 4. An arc groove 42 for anti-slip and conforming to the finger arc is provided on the sleeve 41. After the upper clamping seat 11 and the lower clamping seat 21 clamp the catheter, one can separately hold the sleeve 41 of the upper hand-holding piece 4 by hand to perform the operation of inserting the catheter into the urethra or removing it from the urethra. When performing the operation of inserting the catheter into the urethra or removing it from the urethra, if one holds the upper hand-holding piece 4 and the lower hand-holding piece 5 simultaneously, the gripping force of holding the upper hand-holding piece 4 and the lower hand-holding piece 5 generates a squeezing force on the pivot shaft 3, which easily causes the lower surface of the upper clamping seat 11 and the upper surface of the lower clamping seat 21 not to maintain a tight fit, and further causes the self-catheter in the circular through-hole to be prone to displacement or dropping. Therefore, holding the upper hand-holding piece 4 alone by hand to operate the insertion or removal of the self-catheter can reduce the effect of the gripping force on the pivot shaft 3, and the lower surface of the upper clamping seat 11 and the upper surface of the lower clamping seat 21 can maintain a tight fit.

[0038] Similarly, when separately holding the lower hand-holding piece 5 by hand to operate the insertion or removal of the self-catheter, the length of the lower hand-holding piece 5 is greater than that of the upper hand-holding piece 4. A sleeve 41 provided with an arc groove 42 is sleeved outside the lower hand-holding piece 5, and it can also achieve the purpose of reducing the effect of the gripping force on the pivot shaft 3 and enabling the lower surface of the upper clamping seat 11 and the upper surface of the lower clamping seat 21 to maintain a tight fit. Preferably, the length of the lower hand-holding piece 5 is designed to be greater than that of the upper hand-holding piece 4. At this time, a sleeve 41 is sleeved on the outer surface of the lower hand-holding piece 5. Since the lower hand-holding piece 5 is the part pinched by four fingers and the upper hand-holding piece 4 is the part pinched by the thumb, the pinching area of the lower hand-holding piece 5 is larger than that of the upper hand-holding piece 4. Therefore, when the length of the lower hand-holding piece 5 is greater than that of the upper hand-holding piece 4, it saves production materials and the pinching operation is more comfortable.

[0039] When the lower surface of the upper clamping seat 11 and the upper surface of the lower clamping seat 21 are in contact, the elastic piece is in a non-deformed state. When the upper hand-holding piece 4 and the lower hand-holding piece 5 are pinched tightly, the elastic piece deforms. At this time, the lower surface of the upper clamping seat 11 and the upper surface of the lower clamping seat 21 are separated, and at this time, the catheter can be placed into the circular through-hole or the catheter can be removed. After placing or removing, release the upper hand-holding piece 4 and the lower hand-holding piece 5. Under the action of the elastic piece restoring its shape, the upper hand-holding piece 4 and the lower hand-holding piece 5 separate, and the upper clamping piece 1 and the lower clamping piece 2 actively close, so that the lower surface of the upper clamping seat 11 and the upper surface of the lower clamping seat 21 are in contact to fix the position of the catheter.

[0040] The pivot shaft 3 can be sleeved with a torsion spring. The two ends of the torsion spring respectively contact the upper part and the lower part. Due to the pre-tightening force of the torsion spring, in the case of releasing the upper hand-holding piece 4 and the lower hand-holding piece 5, the torsion spring drives the upper clamping piece 1 and the lower clamping piece 2 to actively close, increasing the closing force of the upper clamping piece 1 and the lower clamping piece 2.

[0041] The upper part and the lower part can be optionally made of lightweight metal titanium alloy, aluminum alloy, etc. The outer surface is smooth, easy to clean and disinfect, and there will be no cleaning dead corners. The outer layer of the upper part and the lower part can also be wrapped with silica gel, and the silica gel outer layer is more corrosion-resistant and has a long service life.

[0042] A viewing mirror 7 is connected to the side of the upper part beside the pivot shaft 3. The viewing mirror 7 can be located above the pivot shaft 3. The viewing mirror 7 can be directly integrally formed with the upper part or bolted. It can also be provided with a viewing mirror mounting seat on the side between the upper hand-held piece 4 and the upper clamping piece 1. The viewing mirror 7 is connected to the viewing mirror mounting seat by snap connection or threaded connection. Both snap connection and threaded connection can detach the viewing mirror 7 from the viewing mirror mounting seat for separate cleaning and disinfection, which is easy to clean and disinfect and not likely to produce cleaning dead corners. When using the female self-catheterization assistance device to clamp the catheter and insert it into the urethra, the user can observe the positions of the catheter and the urethral orifice through the viewing mirror 7 and accurately insert the catheter into the urethral orifice without position deviation.

[0043] Embodiment 2

[0044] Such as Figures 6-10As shown in the figure, the female self-catheterization assistance device disclosed in this patent includes an upper component and a lower component connected by a pivot shaft 3. The upper component includes an upper clamping piece 1 and an upper hand-held piece 4, and the pivot shaft 3 is located between the upper clamping piece 1 and the upper hand-held piece 4. The lower component includes a lower clamping piece 2 and a lower hand-held piece 5, and the pivot shaft 3 is located between the lower clamping piece 2 and the lower hand-held piece 5. The upper hand-held piece 4 and the lower hand-held piece 5 correspond to each other vertically, and the upper clamping piece 1 and the lower clamping piece 2 correspond to each other vertically. An elastic member 6 is provided between the upper hand-held piece 4 and the lower hand-held piece 5. The elastic member 6 can be a compression spring. One end of the compression spring is fixedly connected to the upper hand-held piece 4, and the other end of the compression spring is connected to the lower hand-held piece 5. A detachable upper clamp seat 11 and a detachable lower clamp seat 21 are provided between the upper clamping piece 1 and the lower clamping piece 2. The upper clamp seat 11 is connected to the upper clamping piece 1 and can be connected by one or more bolts. The lower clamp seat 21 is connected to the lower clamping piece 2 and can also be connected by one or more bolts. When not in use, the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 are kept in contact under the action of the pivot shaft 3. The lower surface of the upper clamp seat 11 is provided with a plurality of arc grooves with different diameters, and the upper surface of the lower clamp seat 21 at the corresponding positions of the arc grooves of the upper clamp seat 11 is also provided with a plurality of arc grooves with corresponding dimensions. When the upper clamp seat 11 and the lower clamp seat 21 are in contact, a plurality of circular through holes with different diameters are formed between the upper clamp seat 11 and the lower clamp seat 21. The circular through holes are used to place the catheter. Catheters with different diameters can be placed in the circular through holes with different diameters, and the use is more extensive. The inner circumferences of the plurality of circular through holes with different diameters are 8mm, 10mm, 12mm, 14mm and 16mm respectively, corresponding to self-catheters with specifications of 8F, 10F, 12F, 14F and 16F respectively. The user selects a catheter of one of the specifications according to his own needs and places the self-catheter corresponding to this specification in the corresponding circular through hole.

[0045] The upper clamp seat 11 and the lower clamp seat 21 are made of elastic materials, and silicone pads or rubber pads can be selected for use. They can not only play an anti-slip role when clamping the catheter, but also increase the clamping force on the catheter by using the elastic force when clamping the catheter, and can not produce pressure on the catheter wall to prevent damage to the catheter wall by the hard contact surface.

[0046] The length of the upper hand-held piece 4 is greater than that of the lower hand-held piece 5. A sleeve 41 is sleeved outside the upper hand-held piece 4. An arc groove 42 for anti-slip and conforming to the finger arc is provided on the sleeve 41. After the upper clamp seat 11 and the lower clamp seat 21 clamp the urinary catheter, one can separately hold the sleeve 41 of the upper hand-held piece 4 by hand to perform the operation of inserting the urinary catheter into the urethra or removing it from the urethra. When performing the operation of inserting the urinary catheter into the urethra or removing it from the urethra, if one holds the upper hand-held piece 4 and the lower hand-held piece 5 simultaneously, the gripping force of holding the upper hand-held piece 4 and the lower hand-held piece 5 generates a squeezing force on the pivot shaft 3, which easily causes the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 not to maintain close contact. As a result, the self-urinary catheter in the circular through-hole is prone to displacement or dropping. Therefore, holding the upper hand-held piece 4 alone by hand to operate the insertion or removal of the self-urinary catheter can reduce the effect of the gripping force on the pivot shaft 3, and the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 can maintain close contact.

[0047] When the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 are in contact, the compression spring is in a non-deformed state. When the upper hand-held piece 4 and the lower hand-held piece 5 are pinched, against the acting force of the pivot shaft 3, the compression spring undergoes compression deformation. At this time, the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 are separated. At this time, the urinary catheter can be placed into the circular through-hole or the urinary catheter can be removed. After placing or removing, release the upper hand-held piece 4 and the lower hand-held piece 5. The pivot shaft 3 closes the upper clamping piece 1 and the lower clamping piece 2 under the action of the deformation rebound force. The compression spring also resumes its shape as a passive elastic element. The upper hand-held piece 4 and the lower hand-held piece 5 separate, so that the lower surface of the upper clamp seat 11 and the upper surface of the lower clamp seat 21 are in contact to fix the position of the urinary catheter.

[0048] The upper part and the lower part can be made of lightweight metal titanium alloy, aluminum alloy, etc. The outer surface is smooth, easy to clean and disinfect, and there will be no cleaning dead corners. The outer layer of the upper part and the lower part can also be wrapped with silica gel. The silica gel outer layer is more corrosion-resistant and has a long service life.

[0049] An observation mirror 7 is provided above the upper hand-held piece 4 and the upper clamping piece 1. The observation mirror 7 can be located above the pivot shaft 3 for connection. The observation mirror 7 can be directly integrally formed with the upper part or bolt-connected. Alternatively, an observation mirror mounting seat can be provided above the upper hand-held piece 4 and the upper clamping piece 1. The observation mirror 7 is connected to the observation mirror mounting seat by snap connection or threaded connection. Both snap connection and threaded connection can detach the observation mirror 7 from the observation mirror mounting seat for separate cleaning and disinfection, which is easy to clean and disinfect and not prone to generating cleaning dead corners. When using the female self-catheterization assistance device to clamp the urinary catheter and insert it into the urethra, the user can observe the positions of the urinary catheter and the urethral orifice through the observation mirror 7, and can accurately insert the urinary catheter into the urethral orifice without position deviation.

The description of the above embodiments is only for helping to understand the core idea of the present invention. It should be noted that for those of ordinary skill in the art, any obvious modifications, equivalent substitutions or other improvements made without departing from the inventive concept shall be included within the protection scope of the present invention.
