Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a urine sample collector. Background Art

[0002] The contents of this section merely provide background information related to the present invention and may not constitute prior art.

[0003] In current clinical practice, patients who require urine testing typically receive a disposable urine cup and a urine catheter (also known as a "urine collection tube") from medical staff, who then collect their own urine. During the collection phase, the patient first collects the urine sample in the disposable cup and then pours the sample into the catheter.

[0004] As can be expected, the aforementioned urine sample collection method is not only cumbersome to operate, but also, due to the typically small diameter of a urinary catheter, it is extremely easy for the urine sample to spill during the process of pouring the urine sample from the disposable urine cup into the catheter. Furthermore, conventional disposable urine cups are generally open-topped, making it easy for the patient to carry the disposable urine cup to a collection location, such as a restroom, to contaminate the cup. This increases the risk of contamination of the collected urine sample, which could affect subsequent urine test results. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a urine sample collector, so that patients can collect urine samples more conveniently while reducing the risk of urine sample spilling and contamination.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a urine sample collector, comprising:

[0008] a collecting member defining a collecting chamber and an inlet and outlet communicating with the collecting chamber;

[0009] a liquid inlet component defining a liquid inlet cavity having a transition flow channel and a liquid inlet; the liquid inlet cavity is funnel-shaped, the liquid inlet component is connected to the collecting component, and the transition flow channel is in communication with the collecting cavity through the inlet and outlet;

[0010] The liquid inlet is opened on the side of the liquid inlet cavity with the largest inner diameter, and a removable sealing film for sealing the liquid inlet is provided at the liquid inlet.

[0011] Furthermore, the sealing film is bonded to the liquid inlet component.

[0012] Furthermore, the liquid inlet member has an adhesive portion arranged around the liquid inlet, and a portion of the sealing film close to its outer edge is adhered to the adhesive portion to seal the liquid inlet;

[0013] The sealing film has an easy-to-tear portion protruding from the outer edge of the adhesive portion.

[0014] Furthermore, the liquid inlet member is detachably connected to the collecting member.

[0015] Furthermore, the inlet and outlet are provided on the top of the collecting member;

[0016] The liquid inlet component is provided with a plug-in portion, and the transition flow channel is formed inside the plug-in portion and passes through the plug-in portion; the outer diameter of the plug-in portion matches the inner diameter of the inlet and outlet.

[0017] Furthermore, the outer wall of the plug-in portion is provided with an external thread, and the inner wall of the inlet and outlet is provided with an internal thread adapted to the external thread.

[0018] Furthermore, the collecting member is tubular;

[0019] The urine sample collector further comprises a sealing member, wherein the sealing member is provided with a slot with one side open, and the inner diameter of the slot is adapted to the outer diameter of the collecting member.

[0020] Furthermore, the bottom of the collecting member is in an arc-shaped structure;

[0021] The innermost side of the card slot is provided with an arc-shaped receiving groove adapted to the bottom of the collecting member.

[0022] Furthermore, a suction cup is provided on a side of the sealing member facing away from the opening of the slot.

[0023] Furthermore, the collecting member and the liquid inlet member are both made of transparent materials, and the outer wall of the collecting member is provided with scale lines.

[0024] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0025] The urine sample collector disclosed in the present invention is based on the fact that before the urine sample is collected, the liquid inlet of the liquid inlet member is always blocked by a sealing film and is in a sealed state. Therefore, it can effectively reduce the risk of contamination of the liquid inlet cavity and the collection cavity when the patient carries the urine sample collector to the collection site, thereby reducing the risk of contamination of the urine sample ultimately collected. At the same time, during the process of collecting the urine sample, the urine sample from the patient can directly pass through the liquid inlet cavity on the liquid inlet member and enter the collection cavity of the collection member, eliminating the step of the patient pouring the urine sample from the disposable urine cup into the urinary catheter. This not only simplifies the process of collecting urine samples by the patient himself, but also effectively reduces the risk of spilling the urine sample. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0034] like Figures 1 to 3 As shown, the embodiment of the present utility model discloses a urine sample collector. Figure 1 The figure shows the appearance of an exemplary urine sample collector disclosed in this embodiment. Figure 2 This is an exploded view of the structure of the urine sample collector. Figure 3 is a cross-sectional view of the urine sample collector.

[0035] exist Figures 1 to 3 In the urine sample collector shown, the urine sample collector may include a collecting component 10 and a liquid inlet component 20 .

[0036] In this embodiment, the collecting member 10 is suitable for collecting urine samples that need to be tested. Figure 1 or Figure 2 As shown, the collecting member 10 can be a substantially tubular member. For example, the collecting member 10 can have a structure substantially the same as that of a urinary catheter known in the prior art. Figure 3 A collection chamber 11 is shown which is adapted to receive a urine sample.

[0037] Continue to refer to Figure 3 The collecting member 10 further defines an inlet and outlet 12 in communication with the collecting chamber 11. The inlet and outlet 12 is used to allow urine samples to enter and exit the collecting chamber 11. Specifically, during the urine sample collection phase, the urine sample from the patient can enter the collecting chamber 11 through the inlet and outlet 12. During the urine test phase, medical personnel can pour the urine sample from the collecting chamber 11 through the inlet and outlet 12. The inlet and outlet 12 can be located at the top of the collecting member 10.

[0038] like Figure 1 or Figure 3As shown, the liquid inlet 20 is connected to the collecting part 10, for example, the liquid inlet 20 can be connected to the top of the collecting part 10. The liquid inlet 20 is suitable for allowing the urine sample from the patient to smoothly enter the collecting chamber 11 through the inlet and outlet 12 during the urine sample collection stage. Specifically, the liquid inlet 20 defines a roughly funnel-shaped liquid inlet chamber 21, which has a transition channel 22 and a liquid inlet 23. The transition channel 22 is connected to the collecting chamber 11 through the inlet and outlet 12, and the liquid inlet 23 is opened on the side with the largest inner diameter of the liquid inlet chamber 21. The transition channel 22 can be arranged opposite to the liquid inlet 23. For example, the liquid inlet 23 can be arranged at the top of the liquid inlet chamber 21, and the transition channel 22 can be arranged at the bottom of the liquid inlet chamber 21. Furthermore, the entire liquid inlet 20 can have a roughly funnel-shaped structure to enhance the aesthetics of the urine sample collector.

[0039] At the same time, a removable sealing film 30 is provided at the liquid inlet 23 of the liquid inlet member 20 for sealing the liquid inlet 23. The sealing film 30 can be a common sealing film in the prior art, such as an aluminum foil film, a PVDC film, etc.

[0040] Based on the above arrangement, when it is necessary to collect a urine sample from a patient, the patient can carry the above-mentioned urine sample collector to a collection location such as a toilet to collect the urine sample. It is understandable that, since the liquid inlet 23 on the liquid inlet part 20 is blocked by the sealing film 30 before the urine sample is collected, the liquid inlet cavity 21 on the liquid inlet part 20 and the collection cavity 11 on the collection part 10 can be effectively prevented from being contaminated. After the patient arrives at the collection location, the patient first removes the sealing film 30 on the liquid inlet part 20 to expose the liquid inlet 23, and then the urine sample can be allowed to pass through the liquid inlet 23, the liquid inlet cavity 21, the transition channel 22 and the inlet and outlet 12 in sequence into the collection cavity 11 through the liquid inlet 23.

[0041] It is understood that the urine sample collector using the above design is in a sealed state because the liquid inlet 23 of the liquid inlet member 20 is always blocked by the sealing film 30 before the urine sample is collected. Therefore, it can effectively reduce the risk of contamination of the liquid inlet chamber 21 and the collection chamber 11 when the patient carries the urine sample collector to the collection site, thereby reducing the risk of contamination of the urine sample ultimately collected. At the same time, during the urine sample collection process, the urine sample from the patient can directly pass through the liquid inlet chamber 21 on the liquid inlet member 20 and enter the collection chamber 11 of the collection member 10, eliminating the step of the patient pouring the urine sample from the disposable urine cup into the urinary catheter. This not only simplifies the process of collecting urine samples by the patient himself, but also effectively reduces the risk of spilling the urine sample.

[0042] In this embodiment, the sealing film 30 may be a component adhered to the liquid inlet component 20 , so that the sealing film 30 can be easily removed from the liquid inlet component 20 .

[0043] Specifically, refer to Figure 3 and Figure 4 As shown, the liquid inlet member 20 may have an adhesive portion 24 disposed around the liquid inlet 23, and a portion of the sealing film 30 near its outer edge is bonded to the adhesive portion 24 to seal the liquid inlet 23. Furthermore, the sealing film 30 has an easily tearable portion 31 protruding from the outer edge of the adhesive portion 24, and the easily tearable portion 31 is not connected to the liquid inlet member 20 in any manner.

[0044] In this way, when the sealing film 30 needs to be removed from the liquid inlet part 20 to expose the liquid inlet 23, the sealing film 30 can be quickly torn off from the liquid inlet part 20 by simply pinching the easy-tear portion 31, thereby further improving the convenience of removing the sealing film 30 from the liquid inlet part 20.

[0045] In this embodiment, the collecting member 10 and the liquid inlet member 20 can be made of transparent materials, such as transparent medical plastics, so that the conditions in the liquid inlet cavity 21 and the collecting cavity 11 can be viewed intuitively. Figure 1 The scale lines 13 are shown so that the amount of the urine sample collected in the collecting chamber 11 can be determined with the aid of the scale lines 13 .

[0046] Furthermore, considering that general urine sample collection devices are usually disposable medical devices, and the presence of the liquid inlet 20 will increase the volume of the urine sample collector, it is inconvenient for subsequent medical staff to uniformly store and manage the urine sample collector that has collected urine samples.

[0047] To this end, this embodiment further provides that the liquid inlet member 20 is detachably connected to the collecting member 10. It is understandable that by providing the liquid inlet member 20 as a detachable component, it is not only convenient to separate the collecting member 10 and the liquid inlet member 20 for packaging and transportation during the manufacturing stage, but also, after the patient completes the collection of the urine sample, the patient or medical staff can remove the liquid inlet member 20 from the collecting member 10 and discard it, leaving only the collecting member 10 with the urine sample collected, so that medical staff can store and manage only the collecting member 10 with the urine sample collected.

[0048] The detachable connection between the liquid inlet component 20 and the collecting component 10 can be achieved by, but is not limited to, the following method.

[0049] like Figure 3 and Figure 4As shown, the liquid inlet member 20 is provided with a plug-in portion 25. For example, the plug-in portion 25 can be provided at the bottom of the liquid inlet member 20. The aforementioned transition channel 22 can be formed inside the plug-in portion 25 and pass through the plug-in portion 25. In addition, the outer diameter of the plug-in portion 25 matches the inner diameter of the inlet and outlet 12 on the collecting member 10.

[0050] In this way, the plug-in portion 25 can be inserted into the inlet and outlet 12 on the collecting piece 10 in a plug-in manner, thereby realizing a temporary connection between the liquid inlet part 20 and the collecting piece 10, and since the transition channel 22 runs through the plug-in portion 25, when the plug-in portion 25 is inserted into the inlet and outlet 12, the transition channel 22 will remain connected with the collecting chamber 11.

[0051] Furthermore, the outer wall of the plug-in portion 25 can be provided with an external thread, and the inner wall of the inlet / outlet 12 can be provided with an internal thread that matches the external thread on the plug-in portion 25. In this way, the plug-in portion 25 can be connected to the collecting member 10 by a threaded connection, which is conducive to improving the stability of the liquid inlet 20 after being connected to the collecting member 10.

[0052] In this embodiment, if Figure 2 As shown, the urine sample collector may further include a sealing member 40 , wherein the sealing member 40 is provided with a slot 41 with one side open, and the inner diameter of the slot 41 is adapted to the outer diameter of the collecting member 10 , so that the collecting member 10 can be snapped into the slot 41 of the sealing member 40 .

[0053] Specifically, if Figure 1 or Figure 3 As shown, before the patient collects the urine sample, the bottom of the collecting piece 10 can be snapped into the card slot 41 of the sealing piece 40. At this time, the sealing piece 40 is located at the bottom of the collecting piece 10 and will not affect the patient's normal collection of the urine sample; accordingly, after the urine sample is collected and the liquid inlet 20 is removed from the collecting piece 10 to expose the inlet and outlet 12 on the collecting piece 10, the sealing piece 40 can be removed from the bottom of the collecting piece 10 and installed on the top of the collecting piece 10, that is, the top of the collecting piece 10 is snapped into the card slot 41 of the sealing piece 40. In this way, the sealing piece 40 can be used to seal the inlet and outlet 12 on the collecting piece 10 to reduce the risk of contamination of the urine sample in the collecting cavity 11 when the collecting piece 10 with the urine sample is subsequently transferred.

[0054] Further, such as Figure 2 or Figure 3 As shown, the bottom of the collecting member 10 may be in an arc-shaped structure, so as to further make the structure of the collecting member 10 substantially the same as that of the urinary catheter known in the prior art. Figure 5As shown, the innermost side of the card slot 41 is provided with an arc-shaped receiving groove 42 adapted to the bottom of the collecting member 10. In this way, when the bottom of the collecting member 10 is snapped into the card slot 41, the bottom of the collecting member 10 can be Figure 3 The manner shown is embedded in the arc-shaped receiving groove 42, thereby further improving the stability of the collecting member 10 and the sealing member 40 after being clamped together.

[0055] In addition, refer to Figures 1 to 3 As shown, a suction cup 50 can also be provided on the side of the sealing member 40 that is away from the opening of the card slot 41. In this way, before the urine sample collector is used, the sealing member 40 is clamped to the bottom of the collecting member 10, and the opening of the suction cup 50 faces downward. At this time, the urine sample collector can be fixed to a designated position (e.g., the horizontal surface of the urine test window) by means of the suction cup 50, thereby facilitating medical personnel to place the urine sample collector at the designated position in advance, so that patients can subsequently pick up the urine test sample collector to collect urine samples.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
