Description

Technical Field

[0001] The present invention relates to the field of urine collection equipment, and in particular to a urine collection device and method for urinary care. Background Art

[0002] Midstream urine refers to the urine discharged in the middle stage of urination after the initial part of the urine is discarded. This is because in the initial stage of urination, bacteria, secretions, impurities, etc. in the front part of the urethra may be discharged with the urine, affecting the accuracy of the test results. Midstream urine is less contaminated by the outside world after the initial flushing of the urethra, and can more truly reflect the actual condition of the urinary system. Therefore, it is widely used in clinical tests such as urine routine and urine bacterial culture, and is an important sample for evaluating the health of the urinary system.

[0003] In urine testing, during the collection of midstream urine samples, patients or staff are prone to spillage and contamination when manually pouring urine, and medical staff are prone to contact with samples during the operation, which poses a risk of contamination and infection. In addition, operational errors can easily cause the initial and midstream urine to mix, affecting the accuracy of the test samples. In the structural design of the collection equipment, the initial and midstream urine collection areas are not effectively isolated, and urine can easily flow directly to the midstream collection area due to gravity, causing sample contamination. Summary of the Invention

[0004] The present invention provides a urine collection device and method for urinary care. The technical problems to be solved are: solving the safety hazards and sampling contamination risks caused by manual stage judgment errors and electricity dependence in traditional urine collection technology, automatically identifying urine stage changes and accurately diverting them through a purely mechanical linkage structure, and realizing power-free switching by using the Venturi effect; when sampling, the test tube is inserted and removed to link the opening and closing valve and the silicone layer seal, achieving zero-contact anti-contamination throughout the process, and significantly improving inspection reliability and operational safety.

[0005] In order to achieve the above-mentioned purpose of the invention, the urine collection device for urinary care of the present invention includes a collecting cover, a drainage tube and a collecting box, wherein the collecting box is provided with a collecting cover box, a drainage tube box, an initial urine collecting box and a middle urine collecting box, the collecting cover is arranged in the collecting cover box, the collecting cover box is provided with a box door for taking out the collecting cover for use, the drainage tube is arranged in the drainage tube box, the collecting cover and the drainage tube are detachably connected, the drainage tube is provided with a telescopic hose section, a diversion cavity is provided in the collecting box, a diversion control system is provided in the collecting box, the initial urine collecting box and the middle urine collecting box are arranged side by side, the diversion cavity is located above the initial urine collecting box and the middle urine collecting box, the diversion control system diverts the urine transported by the drainage tube, transports the initial urine to the initial urine collection box, and transports the middle urine to the middle urine collection box.

[0006] Furthermore, the diversion control system includes a blocking control mechanism and a power-assisting mechanism. The blocking control mechanism is arranged in the diversion cavity, and the power-assisting mechanism is arranged in the drainage tube box. The blocking control mechanism is used to control the opening and closing of the initial urine collection box and the middle urine collection box, thereby controlling urine at different stages to enter different collection boxes respectively. The power-assisting mechanism is used to assist in controlling the blocking control mechanism.

[0007] The blocking control mechanism includes a first blocking head, a second blocking head, a main control head and a control board. The bottom of the first blocking head, the second blocking head and the main control head are all provided with a sliding rod. The bottom of the diversion chamber is a urine leakage plate. The first blocking head, the second blocking head and the main control head slide through the urine leakage plate. The sliding rods of the first blocking head, the second blocking head and the main control head are sleeved with a blocking spring. The top of the diversion chamber is provided with a first urine inlet and a second urine inlet. The first blocking head and the second blocking head respectively block the first urine inlet and the second urine inlet. The tops of the first blocking head and the second blocking head are pointed cone-shaped.

[0008] The control plate is arranged in the diversion cavity for transverse sliding. The control plate is provided with a first control groove, a second control groove and a main control groove. The first blocking head, the second blocking head and the main control head are respectively slidably arranged in the first control groove, the second control groove and the main control groove. The first blocking head, the second blocking head and the main control head are all provided with sliding heads. The tops of the first control groove, the second control groove and the main control groove are all provided with openings for each sliding head to slide into each control groove. A slope is provided on one side of the openings of the first control groove, the second control groove and the main control groove. The bottoms of the first control groove and the second control groove are provided with limit grooves for clamping the sliding heads therein.

[0009] A transverse slide is provided on the control board, a first connector is provided on the control board, a second connector is provided on the inner wall of the diversion cavity, the second connector is slidably arranged in the transverse slide, and a return spring is connected between the first connector and the second connector.

[0010] Furthermore, the urine leakage board is provided with perforations for the sliding rods of the first blocking head, the second blocking head and the main control head to slide through. The first urine leakage channel is provided on both sides of the first blocking head on the urine leakage board, and the second urine leakage channel is provided on both sides of the second blocking head on the urine leakage board. The first urine leakage channel is connected to the initial urine collection box, and the second urine leakage channel is connected to the middle urine collection box.

[0011] The outer cover of the return spring is provided with a protective cover.

[0012] Under normal conditions, the first blocking head and the second blocking head are subjected to the upward elastic force of the blocking spring to block the first urine inlet and the second urine inlet. When the first blocking head is pressed, the sliding head of the first blocking head slides in the first control groove, pressing down the slope to make the control plate slide horizontally, and then the sliding head enters the limiting groove to position the first blocking head, so that the first urine inlet is always kept open, so that urine enters from the first urine inlet and enters the primary urine collection box through the first urine leakage channel.

[0013] When the second blocking head is pressed, the control panel slides horizontally, and the sliding head of the first blocking head leaves the limiting groove and is ejected from the first control groove by the elastic force of the blocking spring, while the second blocking head enters the second control groove and is limited by the limiting groove. At this time, the first urine inlet is closed and the second urine inlet is open, and urine enters from the second urine inlet and enters the middle urine collection box through the second urine leakage channel.

[0014] Furthermore, in order to realize automatic control and pressing of the second plugging head, a power-assisting mechanism is provided, which includes an in-tube turbine, a conversion gear, a conversion rack, a pushing slider and a power-storage slider. The in-tube turbine is rotatably arranged in the drainage tube, and the conversion gear is connected to the in-tube turbine. The flow of urine drives the in-tube turbine to rotate, thereby driving the conversion gear to rotate. The conversion rack is meshed with the conversion gear, and the pushing slider is connected to the conversion rack. The pushing slider and the power-storage slider are both longitudinally slidably arranged in the drainage tube box. A longitudinal slide rail for sliding the pushing slider and the power-storage slider is provided in the drainage tube box, and a trigger rod is provided at the bottom of the power-storage slider. The position of the trigger rod corresponds to the second blocking head, the pushing slider is provided with a pushing head, and the force storage slider is provided with a wedge-shaped stopper, which can be retracted into the force storage slider, and the drainage tube box is provided with a force storage spring, which is connected to the force storage spring, and the drainage tube box is provided with a release block, which is wedge-shaped. When the conversion gear drives the conversion rack to slide, it drives the pushing slider to slide, and then the pushing head pushes the stopper, which drives the force storage slider to slide and compresses the spring. When the stopper releases the release block, the stopper is squeezed into the inside of the force storage slider, and then the force storage spring quickly pops out the force storage slider, and then the trigger rod is pushed out, pressing the second blocking head.

[0015] Furthermore, the drainage tube is provided with a pressurized section, which is narrower than the rest of the tube. The turbine is located within the pressurized section. Due to the Venturi effect, when urine enters the pressurized section, the cross-section through which the fluid passes shrinks rapidly, resulting in a surge in flow velocity and pressure, which increases the urine flow rate and, in turn, provides greater driving force for the turbine. Furthermore, since urine has a lower flow rate and flow rate during the first half of the urine flow, the power-assisting mechanism cannot be driven in a timely manner. When urine reaches the middle half of the urine flow, both the flow rate and flow rate increase, driving the power-assisting mechanism and opening the second plug, thereby automatically draining the urine into the middle half of the urine collection box.

[0016] Furthermore, the release block is provided with a hollow groove for the push head to pass through.

[0017] Furthermore, a first slider is provided on the collection box, and the first slider is connected to the first blocking head. A second slider is provided on the collection box, and the second slider is connected to the main control head.

[0018] Furthermore, the first-pass urine collection box and the middle-pass urine collection box are provided with sewage discharge pipe openings.

[0019] Furthermore, a sampling rod is provided at the bottom of the midstream urine collection box, the sampling rod is connected to the midstream urine collection box, and a collection test tube can be plugged into the sampling rod.

[0020] When the urine needs to be tested, the collection tube is inserted into the sampling rod, and the urine automatically enters the collection tube and can be directly used for testing.

[0021] Through the diversion control system, the different flow rates and flow rates during urine discharge are utilized to automatically separate and collect the patient's urine. The midstream urine that is most suitable for testing is collected in the midstream urine collection box, and the frontstream urine that is not suitable for testing is collected in the frontstream urine collection box. A collection tube is set in the midstream urine collection box to directly collect the midstream urine, which is more suitable for testing.

[0022] Furthermore, the bottom of the sampling rod is conical and has an opening. A first support rod is provided in the sampling rod, a telescopic rod is provided on the first support rod, a sealing head is provided at the bottom end of the telescopic rod, and a sealing spring is provided between the sealing head and the first support rod. The sealing head is conical. Under normal conditions, the sealing spring pushes the sealing head to seal the opening of the sampling rod, which will not cause urine to flow out. When urine needs to be collected, the collection test tube is inserted into the bottom of the sampling rod and pushes the sealing head, thereby compressing the sealing spring, so that the opening at the bottom of the sampling rod is opened, thereby allowing urine to flow down and into the test tube.

[0023] Furthermore, the collection test tube is detachably provided with a test tube cap, which is in the shape of a circular ring. A semi-sealed layer is provided inside the test tube cap, and a strip-shaped gap is provided on the semi-sealed layer. The semi-sealed layer is made of silicone. Under normal conditions, due to the elastic properties of the semi-sealed layer itself, the strip-shaped gap is squeezed and sealed so that urine will not flow out. When external force is inserted into it, the strip-shaped gap will open, and the sampling rod will be inserted for drainage. When the test tube is pulled out, the semi-sealed layer will produce a sealing effect again to prevent urine from leaking.

[0024] Furthermore, a second support rod is provided in the test tube, and a blocking piece is provided on the second support rod. The position of the blocking piece corresponds to the blocking head. When the sampling rod is inserted into the collection test tube, the blocking head will contact the blocking piece, and then the blocking head will be pushed into the sampling rod, so that a gap is formed between the blocking head and the opening of the sampling rod, which is convenient for drainage.

[0025] Furthermore, a limiting portion is provided on the sampling rod. When the sampling rod is inserted into the collection test tube, the test tube cap and the limiting portion are limited to prevent the sampling rod from being inserted further downward. At this time, the blocking head is also lifted up by the blocking piece.

[0026] Furthermore, a protective film is provided above the semi-sealed layer in the test tube cap to protect the semi-sealed layer and prevent contamination.

[0027] A urine collection method for urinary care, comprising the following steps:

[0028] S1: The user opens the door, takes out the collection cover, wears and uses the collection cover, and then slides the first slider to limit the first blocking head to open the first urine inlet, and then urinates;

[0029] S2: After the urine is discharged, the second slider is slid to block the first urine inlet and the second urine inlet;

[0030] S3: The first-pass urine is stored in the first-pass urine collection box, and the middle-pass urine is stored in the middle-pass urine collection box. Insert the collection tube into the bottom of the sampling rod and observe the urine flowing into the collection tube. After collecting the required sample volume, pull out the collection tube and the semi-sealed layer will be sealed again to prevent urine leakage. The collection tube can then be used for subsequent testing;

[0031] S4: Remove and discard the collection cover, and clean and disinfect the collection box and its internal structure.

[0032] The beneficial effects of the present invention are as follows: the urine collection device and method for urinary care of the present invention realizes automatic segmented separation and collection of urine through a purely mechanical linkage structure without consuming electricity, utilizes the Venturi effect to accelerate the urine flow rate in the pressurized section of the drainage tube, drives the turbine in the tube to drive the gear rack transmission, and triggers the switching of the blocking mechanism in combination with the instantaneous release of the storage spring. It accurately and automatically captures the dynamic changes of urine flow without the need for electricity, automatically introduces the front-segment urine into the initial collection box, and automatically switches the middle-segment urine to the middle collection box; the middle collection box is equipped with a sampling rod, which automatically realizes sampling when the test tube is inserted, and is leak-proof, realizing pollution-free operation of the entire process of separation, collection, and sampling, and significantly improving the accuracy of urine testing and the safety of clinical use.

A slope 23 is provided on one side of the openings of the first control groove 18, the second control groove 19 and the total control groove 20. A limit groove is provided at the bottom of the first control groove 18 and the second control groove 19 for clamping the sliding head 22 therein; a transverse slide 24 is provided on the control plate 14, and a first connecting head 25 is provided on the control plate 14. A second connecting head 26 is provided on the inner wall of the diversion cavity, and the second connecting head 26 is slidably provided in the transverse slide 24. A return spring 27 is connected between the first connecting head 25 and the second connecting head 26.

[0053] The urine leakage plate 16 is provided with a perforation 28 for the sliding rod 15 of the first blocking head 11, the second blocking head 12 and the main control head 13 to slide through. The first urine leakage channel 29 is provided on both sides of the first blocking head 11 of the urine leakage plate 16, and the second urine leakage channel 30 is provided on both sides of the second blocking head 12 of the urine leakage plate 16. The first urine leakage channel 29 is connected to the initial urine collection box 6, and the second urine leakage channel 30 is connected to the middle urine collection box 7.

[0054] The return spring 27 is covered with a protective sleeve 31 .

[0055] Under normal conditions, the first blocking head 11 and the second blocking head 12 are subjected to the upward elastic force of the blocking spring 17 to block the first urine inlet and the second urine inlet. When the first blocking head 11 is pressed, the sliding head 22 of the first blocking head 11 slides in the first control groove 18, pressing down the slope 23, causing the control plate 14 to slide horizontally, and then the sliding head 22 enters the limiting groove, positioning the first blocking head 11, so that the first urine inlet is always kept open, allowing urine to enter from the first urine inlet and enter the primary urine collection box 6 through the first urine leakage channel 29.

[0056] When the second blocking head 12 is pressed, the control panel 14 slides horizontally, and the sliding head 22 of the first blocking head 11 leaves the limiting groove and is ejected from the first control groove 18 by the elastic force of the blocking spring 17, while the second blocking head 12 enters the second control groove 19 and is limited by the limiting groove. At this time, the first urine inlet is closed and the second urine inlet is open, and urine enters from the second urine inlet and enters the middle urine collection box 7 through the second urine leakage channel 30.

[0057] In order to realize automatic control and pressing of the second plugging head 12, a power-assisting mechanism 10 is provided, which includes an in-tube turbine 32, a conversion gear 33, a conversion rack 34, a pushing slider 35 and a power storage slider 36. The in-tube turbine 32 is rotatably arranged in the drainage tube 2, and the conversion gear 33 is connected to the in-tube turbine 32. The flow of urine drives the in-tube turbine 32 to rotate, and then drives the conversion gear 33 to rotate. The conversion rack 34 is meshed with the conversion gear 33, and the pushing slider 35 is connected to the conversion rack 34. The pushing slider 35 and the power storage slider 36 are both longitudinally slidably arranged in the drainage tube box 5. The drainage tube box 5 is provided with a longitudinal slide rail for sliding the pushing slider 35 and the power storage slider 36. A trigger rod 37 is provided at the bottom of the power storage slider 36. The corresponding second blocking head 12 is provided, and a pushing head 38 is provided on the pushing slider 35, and a wedge-shaped stopper 39 is provided on the force storage slider 36. The stopper 39 can be retracted into the force storage slider 36, and a force storage spring 40 is provided in the drainage tube box 5. The force storage spring 40 is connected to the force storage slider 36, and a release block 41 is provided in the drainage tube box 5. The release block 41 is wedge-shaped. When the conversion gear 33 drives the conversion rack 34 to slide, it drives the pushing slider 35 to slide, and then the pushing head 38 pushes the stopper 39, which drives the force storage slider 36 to slide and compresses the spring. When the stopper 39 releases the release block 41, the stopper 39 is squeezed into the inside of the force storage slider 36, and then the force storage spring 40 quickly pops out the force storage slider 36, and then the trigger rod 37 is pushed out, pressing the second blocking head 12.

[0058] The drainage tube 2 is provided with a pressurized section 42, which is narrower than the rest of the tube. The in-tube turbine 32 is located within the pressurized section 42. Due to the Venturi effect, when urine enters the pressurized section 42, the cross-section through which the fluid passes rapidly decreases, thereby increasing the flow velocity and pressure, thereby increasing the urine flow rate and providing greater driving force to the in-tube turbine 32. Furthermore, since the urine flow rate and flow rate are relatively low during the first half of the urine flow, the assist mechanism 10 cannot be driven in a timely manner. When the urine reaches the middle half of the urine flow, the flow rate and flow rate both increase, thereby driving the assist mechanism 10, opening the second plug 12, and automatically draining the urine into the middle half of the urine collection box 7.

[0059] The release block 41 is provided with a hollow slot 43 for the push head 38 to pass through.

[0060] The collection box 3 is provided with a first slider 44 , which is connected to the first blocking head 11 . The collection box 3 is provided with a second slider 45 , which is connected to the main control head 13 .

[0061] The primary urine collection box 6 and the middle urine collection box 7 are provided with sewage discharge pipes 46 .

[0062] A sampling rod 48 is provided at the bottom of the mid-stream urine collection box 7 . The sampling rod 48 is connected to the mid-stream urine collection box 7 . A collection test tube 49 can be plugged into the sampling rod 48 .

[0063] When the urine needs to be tested, the collection tube 49 is inserted into the sampling rod 48, and the urine automatically enters the collection tube 49 and can be directly used for testing.

[0064] Through the diversion control system, the different flow rates and flow velocities during urine discharge are utilized to realize automatic separation and collection of the patient's urine. The middle urine that is most suitable for testing is collected into the middle urine collection box 7, and the front urine that is not suitable for testing is collected into the front urine collection box 6. A collection tube 49 is provided in the middle urine collection box 7, which can directly collect the middle urine, making it more suitable for testing.

[0065] The bottom of the sampling rod 48 is conical and has an opening. A first support rod 50 is provided in the sampling rod 48. A telescopic rod 51 is provided on the first support rod 50. A blocking head 52 is provided at the bottom of the telescopic rod 51. A blocking spring 17 is provided between the blocking head 52 and the first support rod 50. The blocking head 52 is conical. Under normal conditions, the blocking spring 17 pushes the blocking head 52 to block the opening of the sampling rod 48, which will not cause urine to flow out. When urine needs to be collected, the collection test tube 49 is inserted into the bottom of the sampling rod 48 and pushes the blocking head 52, thereby compressing the blocking spring 17, so that the bottom opening of the sampling rod 48 is opened, thereby allowing urine to flow down and enter the test tube.

[0066] The collection test tube 49 is detachably provided with a test tube cap 54, which is in the shape of a circular ring. A semi-sealed layer 55 is provided inside the test tube cap 54, and a strip-shaped slit 56 is provided on the semi-sealed layer 55. The semi-sealed layer 55 is made of silicone. Under normal conditions, due to the elastic properties of the semi-sealed layer 55 itself, the strip-shaped slit 56 is squeezed and sealed to prevent urine from flowing out. When external force is inserted into it, the strip-shaped slit 56 is opened, and the sampling rod 48 is inserted for drainage. When the test tube is pulled out, the semi-sealed layer 55 produces a sealing effect again to prevent urine from leaking.

[0067] A second support rod 57 is provided in the test tube, and a blocking piece 58 is provided on the second support rod 57. The position of the blocking piece 58 corresponds to the blocking head 52. When the sampling rod 48 is inserted into the collection test tube 49, the blocking head 52 will contact the blocking piece 58, thereby pushing the blocking head 52 into the sampling rod 48, so that a gap is formed between the blocking head 52 and the opening of the sampling rod 48 to facilitate drainage.

[0068] The sampling rod 48 is provided with a limit portion 59 . When the sampling rod 48 is inserted into the collection tube 49 , the tube cap 54 and the limit portion 59 are limited to prevent the sampling rod 48 from being inserted further downward. At this time, the blocking head 52 is also lifted up by the blocking piece 58 .

[0069] A protective film 60 is provided above the semi-sealed layer 55 in the test tube cap 54 to protect the semi-sealed layer 55 from contamination.
