Abstract
Description
Technical Field
[0001] This application relates to the field of biological sample collection devices, and more particularly to a urine sample collection device suitable for bedridden female patients. Background Technology
[0002] For critically ill female patients, who are unable to stand for urine sample collection, urine samples are usually collected while lying down. For patients who are bedridden for a long time, urine samples can be collected by inserting a catheter. For patients who have just started bedridden, or who have not yet had their catheters wiped or who resist having their catheters wiped, open urine sample collection is usually used. Due to the unique physiological structure of women, their urethra is very short, and once they start urinating, it is difficult to control and stop, and the actual amount of urine is uncontrollable. In order to make it easy to hold, the sample collection container is made relatively small. After the sample is full, urination may not have stopped. In a bedridden state, excess urine can easily contaminate the sheets, blankets and the surrounding environment. Summary of the Invention

[0007] As a preferred embodiment, one end of the catheter has a sealing sleeve that fits over the tube connector. The outer surface of the sealing sleeve has a friction ring groove to increase the friction with the fingers and facilitate insertion and removal.
[0008] As a preferred embodiment, the outer arc surface of the urine collection cover is also fixedly connected to a handle, which is located in the vertical direction and close to the upper end of the urine collection cover, so as to facilitate the one-handed holding to realize the taking, putting and adjusting operation of the urine collection cover.
[0009] As a preferred embodiment, the top surface of the urine collection cover is also provided with a convection channel communicating with the buffer cavity to balance the atmospheric pressure inside and outside the buffer cavity.
[0010] As a preferred embodiment, the urine measuring cylinder is provided with a dustproof cap, and the lower end of the catheter extends through the dustproof cap into the urine measuring cylinder. The dustproof cap can reduce the contamination of the urine sample by dust and impurities, and also keep the lower end of the catheter in a stable position.
[0011] As a preferred embodiment, the upper end of the urine measuring cylinder has an inner spiral ring, the outer surface of which has an external thread. The dustproof cap includes an outer spiral ring, the inner wall of which has an internal thread. The outer spiral ring is adapted to engage with the inner spiral ring thread.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0030] like Figure 1-8 The urine sample collection device shown is suitable for bedridden female patients. It includes a urine collection cover 2 and a urine measuring cylinder 4. During use, the urine measuring cylinder 4 needs to be significantly lower than the urine collection cover 2. The urine collection cover 2 will be in direct contact with the patient, while the urine measuring cylinder 4 is usually placed on the ground. The urine collection cover 2 is typically made of plastic. Its vertical projection in the front-to-back direction is triangular, its vertical projection in the left-to-right direction is arc-shaped, and its horizontal projection is also triangular. In other words, the urine collection cover 2 is a curved triangular structure, similar to the crotch area of briefs. Of course, the urine collection cover 2... The thickness is significantly greater than that of briefs. The lower end of the urine-collecting cover 2 is a downward-sloping angle 201 that narrows continuously from top to bottom, which needs to be placed in the patient's buttock crease. The upper end of the urine-collecting cover 2 has an upper covering angle 202 that extends to the left and right, which is placed in the patient's groin. The parts on the left and right sides of the urine-collecting cover 2 between the downward-sloping angle 201 and the upper covering angle 202 are the thigh-fitting surfaces 203. The thigh-fitting surfaces 203 have a certain skin protection and are used to fit against the patient's inner thighs. Therefore, the urine-collecting cover 2 can be clamped and fixed by the legs of a bedridden patient.
[0031] The urine collection cover 2 has a buffer chamber 207. Due to its large internal volume, the buffer chamber 207 can quickly store the patient's urine. The buffer chamber 207 only temporarily stores urine; the urine will quickly drain from the bottom. The inner arc of the urine collection cover 2 has a urine inlet 206 that communicates with the inside of the buffer chamber 207. The urine inlet 206 can completely cover the vulva of a bedridden female patient, ensuring that the patient's urine can enter the buffer chamber 207. The outer arc of the urine collection cover 2 has a tube connection end 204 near the lower end. End 204 is also connected to the inside of buffer chamber 207. The top surface of urine collection cover 2 is also provided with a convection channel 208 that is connected to buffer chamber 207, allowing air to enter and exit buffer chamber 207, thereby balancing the internal and external air pressure of buffer chamber 207 and ensuring the smoothness of urine injection and discharge. A handle 205 is also fixedly connected to the outer arc side of urine collection cover 2. The handle 205 is usually integrally formed with the main body of urine collection cover 2. The handle 205 is located in the vertical direction and close to the upper end of urine collection cover 2, making it convenient for medical staff to hold and hold the urine collection cover 2 for picking up, putting down and adjusting.
[0032] The urine collection cover 2 is connected to the urine catheter 1 through the tube end 204. The urine catheter 1 is made of medical-grade silicone material, which has good flexibility and resilience. One end of the urine catheter 1 has a sealing sleeve 101 that is fitted over the tube end 204 to ensure airtightness and stability of the connection. The outer side of the sealing sleeve 101 is provided with a friction ring groove 102 to increase the friction with the fingers, thereby making it easier to insert and remove the sealing sleeve 101.
[0033] The lower end of the catheter 1 extends into the urine measuring cylinder 4 to guide the urine received by the urine collection cover 2 into the larger urine measuring cylinder 4. The outer side of the urine measuring cylinder 4 is marked with graduation lines 403 to indicate the maximum storage capacity of the urine measuring cylinder 4. The bottom of the urine measuring cylinder 4 is provided with a cushioning pad 404 made of rubber material. Since the urine measuring cylinder 4 is usually made of glass and is fragile, the rubber cushioning structure can effectively prevent the urine measuring cylinder 4 from making hard contact with the ground and reduce the impact noise generated during placement.
[0034] A dust cover 3 is provided on the urine measuring cylinder 4 to reduce the amount of dust and debris falling into the urine measuring cylinder 4, effectively reducing the probability of contamination of the collected urine sample. The lower end of the catheter 1 extends into the urine measuring cylinder 4 through the dust cover 3. Restricted by the dust cover 3, the catheter 1 can smoothly guide the urine into the urine measuring cylinder 4, while also preventing the lower end of the catheter 1 from being submerged below the liquid surface, which would increase the resistance to the flow of liquid. To achieve a stable connection, the upper end of the urine measuring cylinder 4 is usually equipped with a coaxial inner spiral ring 401. The outer surface of the inner spiral ring 401 has external threads. The specific structure of the dust cover 3 includes an outer spiral ring 301, the inner wall of which has internal threads. In this way, the outer rotating ring 301 can be threadedly engaged with the inner rotating ring 401, which has good engagement stability and the threaded engagement surface has good leak-proof characteristics. Therefore, even if the urine measuring cylinder 4 is tilted, the urine stored inside will not flow out quickly and contaminate the ground. The outer surface of the outer rotating ring 301 is provided with a friction groove 302 to increase the friction with the hand, making it easy to tighten or loosen the dust cover 3. The outer surface of the inner rotating ring 401 and the two end faces of the urine measuring cylinder 4 form a clearance ring groove 402, which fits with the bottom surface of the outer rotating ring 301 to form an annular sealing surface, further improving the leak-proof capability of the mating end face of the dust cover 3 and the urine measuring cylinder 4.
[0035] The upper end of the outer rotating ring 301 has a frustum-shaped transition platform 303. A cylindrical friction handle 304 is fixedly connected to the transition platform 303. A tube insertion port 305 is opened in the center of the friction handle 304, which passes through the upper and lower end faces, for the lower end of the urinary catheter 1 to pass through. The lower end of the urinary catheter 1 passes through the tube insertion port 305 and is press-fitted with the friction handle 304 to maintain a stable relative position. The lower end of the urinary catheter 1 is not easy to slip out of the tube insertion port 305. The friction handle 304 has an exhaust channel 306 that passes through the upper and lower end faces. During the continuous injection of urine, the urine measuring cylinder 4 will expel excess air through the exhaust channel 306 to ensure the smooth injection of urine.
[0036] Working principle: In use, first, place the sealing sleeve 101 of the catheter 1 over the tube end 204 of the urine collection cover 2. Then, grasp the urine collection cover 2 using the handle 205, inserting the lower corner 201 between the legs of the bedridden female patient, allowing the catheter 1 to extend under the bed. The lower end of the catheter 1 passes through the tube insertion port 305 of the dustproof cover 3 and extends into the urine measuring cylinder 4. Then, push the urine collection cover 2 closer to the patient's groin until the two upper corners 202 sink into the groin on both sides of the patient. At this point, the urine collection port 206 completely covers the vulva of the female patient in a supine position. Let the patient's legs close together to clamp the urine collection cover 2, then release. When the patient feels the urge to urinate, the urine will quickly enter the buffer chamber 207 through the urine collection port 206. The urine level in chamber 207 rises rapidly, and excess air in chamber 207 is expelled through convection channel 208. Due to gravity, the urine in chamber 207 flows through tube connector 204 at the bottom into catheter 1, and finally into the large-capacity urine measuring cylinder 4. When the patient finishes urinating, the urine in chamber 207 continues to fall under gravity, and outside air enters chamber 207 through convection channel 208 to fill the empty space. Finally, grasp handle 205 again to lift urine collection cover 2, perform simple wiping and cleaning of the patient's vulva, remove catheter 1, unscrew dust cap 3, and urine sample can be taken from urine measuring cylinder 4 as needed for testing.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
