Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular, to a midstream urine collection device. Background Art

[0002] Currently, when conducting routine urine tests, the front urine may be infected by bacteria in the urethra, so it is not suitable for testing. Midstream urine is relatively clean and can clearly reflect the condition of the urinary system. Back urine is also easily contaminated, so it is not recommended; when taking urine test specimens, morning urine is less affected by diet and exercise, and can more accurately reflect the indicators; therefore, when doing tests in hospitals, the patient's midstream morning urine will be selected.

[0003] For patients with urinary catheters, medical staff currently collect urine directly from the catheter. However, since the catheter continuously outputs urine in the bladder to a urine bag, it is impossible to determine whether the collected urine is morning urine, which affects the accuracy of urine testing.

[0097] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0098] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0099] like Figures 1 to 15 As shown, the mid-stream urine collection device 100 of the present application includes: a front-stage container 110, a middle-stage container 120, a base 130, a movable component 100a and a pressure detection component 100b.

[0100] The front container 110 is used to hold the front urine, and the middle container 120 is used to hold the middle urine. Exemplarily, both the front container 110 and the middle container 120 can be collection tubes. The base 130 has a liquid inlet connector 131 for connecting to a urinary catheter, a first liquid outlet connector 132 for connecting to a urine bag, and a second liquid outlet connector 133 for connecting to the middle container 120.

[0101] The movable component 100a has a first chamber 140a, a second chamber 140b and a third chamber 140c that are isolated from each other. The movable component 100a is movably connected to the base 130 so that the movable component 100a has a first state, a second state and a third state; when the movable component 100a is in the first state, the first chamber 140a is connected between the liquid inlet connector 131 and the first liquid outlet connector 132; when the movable component 100a is in the second state, the second chamber 140b is connected between the liquid inlet connector 131 and the front container 110; when the movable component 100a is in the third state, the third chamber 140c is connected between the liquid inlet connector 131 and the middle container 120.

[0102] It should be noted that the first state is at least used for nighttime urination control, the second state is at least used for outputting front urine, and the third state is at least used for obtaining midstream urine.

[0103] The pressure detection component 100b is configured to connect the first chamber 140a with the first liquid outlet connector 132 when the liquid pressure in the first chamber 140a is greater than a preset pressure value. That is, the pressure detection component 100b detects the liquid pressure in the first chamber 140a, and indirectly detects the liquid pressure in the patient's bladder. When the liquid pressure in the first chamber 140a is greater than the preset pressure value, urination is performed to prevent the patient from holding urine. When the liquid pressure in the first chamber 140a is greater than the preset pressure value, the first chamber 140a and the first liquid outlet connector 132 are closed to ensure that there is a sufficient amount of urine in the patient's bladder.

[0104] By adopting the above technical solution, a pressure detection device is set to detect the liquid pressure in the first chamber 140a connected to the catheter. Only when the liquid pressure is greater than a preset pressure value, the first chamber 140a is connected to the first liquid outlet connector 132 to release urine in the bladder, so that the bladder maintains sufficient urine for collecting morning urine, thereby improving the accuracy of urine detection.

[0105] At the same time, the present application is also provided with an active component 100a, which is connected to the liquid inlet connector 131 by switching different chambers, so that the collection device of the present application can accurately collect mid-stream urine.

[0106] In some embodiments, the base 130 is configured to have an activity space 130 a and a first channel 130 b .

[0107] The movable space 130a is used to accommodate the movable component 100a. The first channel 130b is connected between the first liquid outlet joint 132 and the movable space 130a. The pressure detection component 100b includes: a first core 191 and a first elastic member 192.

[0108] The first core 191 is slidably disposed inside the first channel 130b; the first elastic member 192 is sleeved on the first core 191 and abuts against the first core 191. The first core 191 blocks one end of the first channel 130b close to the activity space 130a under the elastic force of the first elastic member 192. When the first chamber 140a corresponds to the first channel 130b and the liquid pressure in the first chamber 140a is greater than the elastic force of the first elastic member 192, the first core 191 moves away from the first chamber 140a under the action of the liquid pressure, so that the first channel 130b is connected to the first chamber 140a, so that the liquid in the first chamber 140a can be discharged along the first channel 130b.

[0109] By adopting such a solution, the liquid pressure in the first chamber 140a is detected through the cooperation of the first core 191 and the first elastic member 192, so as to maintain a sufficient amount of urine in the patient's bladder while avoiding the problem of excessive urine retention.

[0110] Exemplarily, the first elastic member 192 is a coil spring.

[0111] In some embodiments, the movable assembly 100 a includes a movable base 140 , a movable cover 151 , and a second elastic member 152 .

[0112] The movable base 140 and the movable cover 151 are rotatably disposed in the movable space 130a, respectively. The movable base 140 has a plurality of partitions 141 to divide the inner space of the movable base 140 into a first chamber 140a, a second chamber 140b and a third chamber 140c. The first chamber 140a, the second chamber 140b and the third chamber 140c are spaced apart in the circumferential direction. The movable cover 151 is covered on the movable base 140, and the first chamber 140a, the second chamber 140b and the third chamber 140c are respectively surrounded by the movable base 140 and the movable cover 151. The second elastic member 152 is used to provide an acting force to the movable cover 151 so that the movable cover 151 remains covered with the movable base 140, so as to prevent the liquid in each chamber from overflowing and to prevent the relative movement between the movable base 140 and the movable cover 151 from being affected.

[0113] The movable base 140 further has a first communication port 140d communicating with the first chamber 140a, a second communication port 140e communicating with the second chamber 140b, and a third communication port 140f communicating with the third chamber 140c.

[0114] Exemplarily, the second elastic member 152 is a coil spring.

[0115] By adopting such a solution, through the provision of multiple chambers and connecting ports, nighttime urination, front urine and middle urine are kept isolated and there is no contamination between them.

[0116] In some embodiments, the movable cover body 151 is provided with a transfer joint 151a, which is connected to the liquid inlet joint 131 through a hose 153; when the movable component 100a is in the first state, the transfer joint 151a corresponds to the first chamber 140a, so that the urine in the catheter can be input into the first chamber 140a.

[0117] It can be understood that the hose 153 has a suitable length and flexibility and will not affect the rotation of the movable cover 151 .

[0118] The midstream urine collection device 100 further includes a rotating shaft 161. The rotating shaft 161 is rotatably connected to the base 130 so that the rotating shaft 161 can rotate around a central axis C1. The movable cover 151 is non-rotatably connected to the rotating shaft 161 so that the rotating shaft 161 can drive the intermediate joint 151a to rotate to correspond to the second chamber 140b.

[0119] With such a solution, the movable cover 151 can be driven to rotate relative to the movable base 140 through the setting of the rotating shaft 161, so that the transfer joint 151a can be switched to correspond to the second chamber 140b, thereby realizing the collection of the front urine.

[0120] Exemplarily, a plurality of anti-rotation protrusions are provided on the outer wall of the rotating shaft 161 at intervals along the circumferential direction, and the movable cover body 151 is provided with a plurality of anti-rotation grooves matching with the anti-rotation protrusions, thereby realizing an anti-rotation connection.

[0121] In some embodiments, the midstream urine collecting device 100 further includes: a driven gear 162 , a driving worm 163 and a prime mover 164 .

[0122] The driven gear 162 is fixedly connected to the rotating shaft 161; the active worm 163 is rotatably connected to the base 130 and meshes with the driven gear 162 to achieve a reduction transmission; the prime mover 164 is fixedly connected to the base 130 and is used to drive the active worm 163 to rotate.

[0123] For example, the prime mover 164 may be a motor connected to a controller, which controls the motor to start at a predetermined time (eg, the morning urine collection time). The controller timing controls the motor to work using existing technology, which will not be described in detail.

[0124] By adopting such a solution, the movable cover body 151 is driven to rotate by the prime mover 164, thereby realizing automatic and timely collection of morning urine and reducing the workload of medical staff.

[0125] In some embodiments, the inner wall of the base 130 is configured to have a guide slide 134. The guide slide 134 includes a first guide segment 134a extending in a circumferential direction and a second guide segment 134b extending in a spiral shape.

[0126] The movable base 140 has: a guide protrusion 142, at least a portion of which is embedded in the guide slide 134, and the guide protrusion 142 is arranged on the outer wall of the movable base 140. Through the cooperation between the guide protrusion 142 and the guide slide 134, the movable base 140 can move along the extension path of the guide slide 134 to the third chamber 140c corresponding to the transfer joint 151a.

[0127] When the movable assembly 100a is in the first state and the second state, the movable base 140 is in the first position, and the guide protrusion 142 is located in the first guide section 134a;

[0128] When the movable assembly 100 a is in the third state, the movable base 140 moves to the second position, and at this time the guiding protrusion 142 is located in the second guiding section 134 b.

[0129] By adopting such a solution, the movable base 140 can be limited to move along a preset trajectory through the cooperation between the guide slide 134 and the guide protrusion 142 .

[0130] In some embodiments, the movable cover 151 and the movable base 140 rotate in opposite directions. When the first state is switched to the second state, the guide protrusion 142 is located in the first guide section 134a. When the movable cover 151 rotates relative to the movable base 140, the movable base 140 is prevented from being driven to rotate by the rotating shaft 161 or the movable cover 151 due to the stopping effect of the end wall of the first guide section 134a.

[0131] In some embodiments, the helix angle of the active worm 163 is smaller than the friction angle, and the driven worm gear cannot drive the active worm 163 to rotate, thereby achieving self-locking and ensuring that the rotation of the movable base 140 does not affect the state of the movable cover 151.

[0132] In some embodiments, the front container 110 is detachably connected to the opening of the movable space 130 a ; that is, the second communication port 140 e penetrates the movable base 140 along the axial direction.

[0133] The front container 110 includes a container body 111 and a buoyancy member 112 .

[0134] The container body 111 has a receiving space and a guide plate located in the receiving space; the buoyancy member 112 is used to move toward the base 130 under the buoyancy provided by the front urine in the receiving space, so as to push the movable base 140 to rotate along the first guide section 134a. Among them, at least part of the rotating shaft 161 is penetrated through the guide plate, and at least part of the rotating shaft 161 can be slidably penetrated through the buoyancy member 112, and the buoyancy member 112 is arranged in the receiving space and is located on the side of the guide plate away from the base 130.

[0135] It can be understood that the buoyancy member 112 is made of a low-density material, such as aerogel, and its exterior may be wrapped with a packaging film (such as a PET film) to isolate urine.

[0136] The buoyancy member 112 has a plurality of push portions 112a, and a first inclined surface 112b is disposed at the top of the push portion 112a; the guide plate is provided with a plurality of guide holes for the push portion 112a to pass through, so as to guide the push portion 112a. A driven portion 143 is disposed on the side of the movable base 140 facing the front container 110, and a second inclined surface 143a is disposed at the bottom of the driven portion 143; when the first inclined surface 112b contacts the second inclined surface 143a, the movable base 140 can be pushed to rotate relative to the base 130.

[0137] With such a solution, by providing the buoyancy member 112 , the movable base 140 can partially move under the push of the buoyancy member 112 , so that the guide protrusion 142 moves to the junction of the first guide section 134 a and the second guide section 134 b .

[0138] Furthermore, since the density of the buoyancy member 112 is relatively low, when it passes through the guide hole, the height of the urine on the lower side of the guide plate may not reach the guide plate, and at this time, the buoyancy member 112 alone may not be enough to push the movable base 140. In the present application, the two sides of the guide plate are connected only through the guide hole, and the guide hole can be blocked after the push portion 112a penetrates the guide hole, so that the liquid in the space on the side of the guide plate close to the movable base 140 is quickly filled, and the movable base 140 is easier to be pushed by the liquid pressure of this part.

[0139] Since the thrust of the buoyancy member 112 is effective, it cannot completely realize the position switching of the movable base 140. In some embodiments, the midstream urine collection device 100 further includes: a third elastic member 171, a thrust member 172 and a retaining spring 173.

[0140] The third elastic member 171 is used to push the movable base 140 to move along the second guide section 134b, so that the movable base 140 spirally rises along the second guide section 134b under the action of the third elastic member 171 until the third chamber 140c corresponds to the transfer joint 151a, and the third connecting port 140f is connected to the second liquid outlet, thereby realizing the collection of mid-section urine.

[0141] Specifically, the thrust member 172 is sleeved on the rotating shaft 161 and abuts against the third elastic member 171; one end of the third elastic member 171 abuts against the movable base 140, and the other end abuts against the thrust member 172. When the guide protrusion 142 is located in the first one-way section, the third elastic member 171 is in a compressed state. At least part of the clamping spring 173 is embedded in the rotating shaft 161 to limit the position of the thrust member 172. Accordingly, the rotating shaft 161 has a clamping groove corresponding to the clamping spring 173.

[0142] Exemplarily, the third elastic member 171 is a coil spring.

[0143] In some embodiments, the midstream urine collecting device 100 includes: a fixing seat 181 , a second core 182 and a fourth elastic member 183 .

[0144] The fixed seat 181 is fixedly connected to the partition 141 between the first chamber 140a and the third chamber 140c. The fixed seat 181 has a first interface 181a connected to the third chamber 140c, a second interface 181b connected to the first chamber 140a, and an intermediate channel 181c located between the first interface 181a and the second interface 181b; the second core 182 is movably arranged in the intermediate channel 181c.

[0145] The fourth elastic member 183 is located inside the fixed seat 181, and one end of the fourth elastic member 183 is abutted against the second core 182. The fourth elastic member 183 is used to push the second core 182 toward the first interface 181a, so that when the liquid pressure in the third chamber 140c is greater than the elastic force of the fourth elastic member 183, the liquid in the third chamber 140c flows unidirectionally to the first chamber 140a.

[0146] With such a solution, after a sufficient amount of middle urine is collected in the middle container 120, the liquid pressure in the third chamber 140c gradually increases. When the liquid pressure is greater than the elastic force of the fourth elastic member 183, the second core 182 is pushed to move in the direction of compressing the fourth elastic member 183. At this time, the first interface 181a, the middle channel 181c, and the second interface 181b are in a conducting state, so that the urine in the third chamber 140c can be diverted to the first chamber 140a for discharge.

[0147] Exemplarily, the fourth elastic member 183 is a coil spring.

[0148] In some embodiments, the base 130 further includes: a third liquid outlet connector 135 .

[0149] The third liquid outlet connector 135 is configured to communicate with the first communication port 140d when the third chamber 140c rotates to correspond to the transfer connector 151a. The third liquid outlet connector 135 and the second liquid outlet connector 133 are located at the same axial position, and the height of the third liquid outlet connector 135 and the second liquid outlet connector 133 is higher than that of the first liquid outlet connector 132.

[0150] With such a solution, the urine remaining in the first chamber 140a and the urine entering from the third chamber 140c can be discharged through the provision of the third liquid outlet joint 135, thereby ensuring smooth urination.

[0151] It should be noted that the third liquid outlet connector 135 can also be connected to a urine bag.

[0152] In some embodiments, in the circumferential direction, the first liquid outlet joint 132 is located between the second liquid outlet joint 133 and the third liquid outlet joint 135, and the angle between the first liquid outlet joint 132 and the second liquid outlet joint 133 is 90°, and the angle between the first liquid outlet joint 132 and the third liquid outlet joint 135 is 90°; the angle between adjacent partitions 141 is 120°. This makes the positions of the liquid outlet joints relatively concentrated, and facilitates the installation of the base 130 on the bed on the opposite side of the first liquid outlet joint 132.

[0153] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
