Description

Technical Field

[0001] This utility model belongs to the field of medical testing devices, and in particular relates to a membrane tank, forming mechanism and forming device for collecting urine. Background Technology

[0002] Urine testing is a medical diagnostic method that includes routine urinalysis, detection of formed elements in urine (such as red blood cells and white blood cells), quantitative determination of protein components, and urine enzyme testing. Urine testing is of great value in clinical diagnosis, assessment of treatment efficacy, and prognosis.

[0003] Before urine is tested, the sampler needs to collect urine using a urine collection tube and then deliver the sample to the testing personnel. During the testing process, the testing personnel will take samples for analysis.

[0004] When collecting samples, the sampler usually first uses a large-mouthed urine cup to collect the urine sample, and then pours the urine sample from the urine cup into the urine collection tube. The whole process of the sampler has the following obvious disadvantages: uncomfortable posture, small mouth of urine cup makes it difficult to align, difficult to control the collection volume, easy to overflow or spill, easy to splash on hands, cup side and ground hygiene contamination, sample spillage during transfer, sample tube label may get wet or even lose information, etc.

[0005] This not only affects the amount of urine sample collected and the degree of sterility, but also does not meet hygiene requirements. The sampler cannot urinate comfortably and freely at once, which affects their mood. In particular, due to the limitations of women's physiological structure, these disadvantages are more obvious.

[0006] Existing technologies mostly address this by enlarging the opening of the urine cup, designing a cup opening specifically to fit the female genitalia, and lengthening the handle. However, these methods still cannot free up the hands, and the urine sample still needs to be transferred to a sample tube after collection. Utility Model Content

[0007] The primary objective of this invention is to provide a membrane tank for collecting urine, thereby addressing the aforementioned problems caused by existing instruments used by samplers when collecting urine. This invention also provides a molding mechanism for the membrane tank used in the aforementioned membrane tank. Furthermore, this invention provides a molding device for the aforementioned molding mechanism.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] As a first aspect of this application, a membrane tank for collecting urine includes...

[0010] A membrane roll is made by rolling up a thin film.

[0011] The forming mechanism includes a film feeding chamber, a film receiving chamber, a power unit, and a forming device. The film feeding chamber and the film receiving chamber are spaced apart. The power unit is located in the film receiving chamber. The film roll is located in the film feeding chamber. The end of the film in the film roll is connected to the power unit.

[0012] The molding apparatus includes a substrate disposed on one side of the film, and the substrate has a first extension section extending toward the other side of the film, the end of the first extension section being located obliquely above the substrate;

[0013] Under the action of the film feeding chamber, the film receiving chamber, and the first extension section, the film forms a film tank.

[0014] Preferably, the second extension segment is formed by the top of the substrate extending upwards.

[0015] Preferably, the height of the extension end of the second extension segment is greater than the height of the extension end of the first extension segment.

[0016] Preferably, the upper surface of the first extension is a curved surface and / or an inclined surface.

[0017] Preferably, the membrane tank for collecting urine proposed in this application further includes a support rod, which is disposed inside the membrane placement chamber, and the membrane roll is sleeved on the support rod.

[0018] Preferably, the membrane tank for collecting urine proposed in this application further includes a damping element disposed between the membrane dispensing chamber and the membrane roll.

[0019] Preferably, the height of the film-dispensing chamber is greater than the height of the film-receiving chamber.

[0020] Preferably, there are two forming devices, which are spaced apart and located between the film feeding chamber and the film receiving chamber.

[0021] Preferably, the membrane tank for collecting urine proposed in this application further includes a pressure membrane sheet, which includes a snap-fit ​​portion and an extension portion. The snap-fit ​​portion is provided with a snap-fit ​​interface adapted to the extension end of the first extension portion. The pressure membrane sheet is snapped onto the first extension portion through the snap-fit ​​interface. The thin film constituting the membrane tank is slidably connected to the lower surface of the extension portion.

[0022] As a second aspect of this application, a forming mechanism for a membrane tank for collecting urine is configured to form the membrane tank as described above.

[0023] As a third aspect of this application, a forming device for a membrane tank for collecting urine is configured to form the forming mechanism described above.

[0024] This utility model discloses a membrane tank, forming mechanism, and forming device for collecting urine. Its advantages are: ease of use, freeing the sampler's hands and improving the sampler's experience; and high reliability. Specifically, it is reflected in:

[0025] First, the membrane trough proposed in this application is placed at the urination site. Using disposable membrane to construct the trough, the sampler does not need to hold the urine cup to collect urine, making it more convenient and freeing up their hands, thus improving the sampler's experience. Simultaneously, a power device is used to roll the used membrane into a collection chamber, and a clean, uncontaminated membrane from the placement chamber is pulled out to form a new membrane trough for subsequent samplers. This ensures that samples collected through the membrane trough proposed in this application will not cross-contaminate with samples from other samplers, thus demonstrating high reliability.

[0026] Secondly, since the membrane tank proposed in this application is placed at the urination site, both the elderly and children can collect urine for sampling on their own without the assistance of others, which further enhances the sampling experience.

[0027] Furthermore, the use of damping components ensures that the film located between the film feeding chamber and the film receiving chamber has a certain tension, thereby ensuring the formation of the film tank and further demonstrating its high reliability.

[0028] Finally, by using a membrane pressing device, it is ensured that after each sampler collects the used film into the film collection bin via a power unit, a new film tank can be formed from the clean and uncontaminated film in the film storage bin, which once again demonstrates the high reliability.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] As the first aspect of this embodiment, such as Figure 1 , Figure 2 As shown, a membrane tank 1 for collecting urine includes a forming mechanism 200 and a thin film 100 constituting the membrane tank 1; wherein the thin film 100 is rolled into a film roll; the forming mechanism 200 includes a film feeding chamber 2, a film receiving chamber 3, a power unit 4, and a forming device 5, wherein the film feeding chamber 2 and the film receiving chamber 3 are spaced apart, the power unit 4 is located in the film receiving chamber 3, the film roll is located in the film feeding chamber 2, and the end of the thin film 100 in the film roll is connected to the power unit 4; the forming device 5 includes a base 51, the base 51 is located on one side of the thin film 100, and the base 51 has a first extension section 52 extending toward the other side of the thin film 100, the end of the first extension section 52 being located obliquely above the base 51; under the action of the film feeding chamber 2, the film receiving chamber 3, and the first extension section 52, the thin film 100 forms the membrane tank 1.

[0037] It should be understood that, in this embodiment, the film 100 refers to a film made of plastic or synthetic materials such as PE. Typically, a mandrel is used to fix one end of the film 100 to the mandrel, and the other end is wound around the mandrel to form a film roll, such as the commonly seen plastic wrap. Therefore, the end of the film 100 in the film roll is connected to the end of the film 100 described in the power device 4, which refers to the other end of the film roll that is wound around the mandrel.

[0038] It should also be understood that the substrate 51 being located on one side of the film 100 means that the end of the film 100 passes through one side of the substrate 51 and is then connected to the power device 4. Since the film 100 can be bent at will or its direction can be changed at will, the positions of the film loading chamber 2, the film receiving chamber 3 and the forming device 5 do not necessarily have to be fixed. Moreover, the forming device 5 can be added as needed, or multiple first extension sections 52 can be provided on one substrate 51 of the same forming device 5.

[0039] To further illustrate that the positions of the film-dispensing chamber 2, the film-receiving chamber 3, and the forming device 5 do not necessarily have to be fixed, the following possible arrangements are listed. It should be understood that the following arrangements are not exhaustive. Any arrangement that utilizes the concept of this application but only changes the positional relationship between the film-dispensing chamber 2, the film-receiving chamber 3, and the forming device 5 should be understood as being within the scope of protection of this application.

[0040] The first implementation method, such as Figures 1 to 3 As shown, the film feeding chamber 2 and the film receiving chamber 3 are located at both ends of the forming device 5, and the number of forming devices 5 is at least one, that is, the film feeding chamber 2, the forming device 5 (if there are multiple, they can be arranged in sequence) and the film receiving chamber are arranged in sequence.

[0041] In the second embodiment, both the film-dispensing chamber 2 and the film-receiving chamber 3 are located at one end of the forming device 5. For example, they can be... Figures 1 to 3 The film receiving bin 3 is moved to the film dispensing bin 2. At this time, the end of the film 100 starts from the film dispensing bin 2, passes through the forming device 5, and then folds back from the other side of the forming device 5 into the film receiving bin 3; or it can be that... Figures 1 to 3 The film feeding chamber 2 is moved to the film receiving chamber 3. At this time, the end of the film 100 extends from the other side of the forming device 5 opposite to the first extension section 52 to the end of the forming device 5 away from the film feeding chamber 2, bends around the end of the film feeding chamber 2 to the side of the forming device 5 where the first extension section 52 is provided, and then forms a film groove 1 under the action of the first extension section 52 and is connected to the power device 4. It should be noted that in this embodiment, the optimal number of forming devices 5 is two, or the base 51 of the forming device 5 is provided with at least two first extension sections 52.

[0042] In the third embodiment, when multiple forming devices 5 are provided, the multiple forming devices 5 are arranged sequentially at intervals, and the first extension sections 52 are all located on the same side. In this case, the film dispensing chamber 2 can be located either in the extension direction of the multiple forming devices 5 or on the other side of the multiple forming devices 5 opposite to the first extension section 52. That is, the film dispensing chamber 2 can be located between two adjacent forming devices 5. Similarly, the film receiving chamber 3 can also be located in the extension direction of the multiple forming devices 5 or between two adjacent forming devices 5.

[0043] It should be noted that in this embodiment, the power device 4 refers to a device capable of outputting rotational motion, such as a motor. The end of the film 100 in the film roll is connected to the power device 4 by connecting the end of the film 100 to the output shaft of the power device 4. When the power device 4 is a motor, the end of the film 100 can be directly connected to the output shaft of the motor, or a mandrel can be used to connect the mandrel to the output shaft of the motor, and then the end of the film 100 can be connected to the mandrel connected to the output shaft of the motor.

[0044] It should also be noted that, due to the elasticity of the film 100, when the film 100 is tightened by the film release chamber 2 and the film collection chamber 3, as the first extension section 52 extends from the substrate 51 toward the other side of the film 100, the film 100 in contact with the upper surface of the first extension section 52 will also bend upward, thereby forming a "U" or "V" shape with the film 100 that is not in contact with the upper surface of the first extension section 52, that is, forming a groove. In other words, under the action of the film release chamber 2, the film collection chamber 3 and the first extension section 52, the film 100 forms a film groove 1.

[0045] It should be understood that in this embodiment, the film 100 is in contact with the upper surface of the first extension 52. Depending on the specific shape of the upper surface of the first extension 52, the film 100 may be in contact with the entire upper surface of the first extension 52 or only with a portion of the upper surface of the first extension 52.

[0046] It should also be understood that the first extension segment 52 can be a partial extension of one side of the base 51 or an integral extension of one side of the base 51.

[0047] To illustrate the advantages of the membrane tank 1 for collecting urine proposed in this embodiment, the method of use by the sampler during sampling is further explained, such as... Figure 2 As shown, based on different functions, it is divided into a collection area A and a sampling area B. Collection area A is where the sampler can urinate, that is, this area can be used to collect the sampler's urine. Sampling area B is where the sampler can take samples, and sampling can be done either after urination and before the urine has completely flowed out of the membrane tank 1, or during urination. Obviously, since the two ends of the membrane 100 are connected to the membrane release chamber 2 and the membrane collection chamber 3 respectively, and the membrane 100 forms a membrane tank 1 with both collection area A and sampling area B under the action of at least the first extension section 52, the sampler does not need to hold the container for collecting urine with both hands, thus freeing the sampler's hands.

[0048] Furthermore, it should also be understood that the membrane tank 1 for collecting urine proposed in this embodiment can be directly placed at the urination site. For easier placement, i.e., for easier installation and setup of the membrane tank 1 in this embodiment, as follows... Figure 3 As shown, the optimal feature is the addition of a fixed support 9, which integrates the film placement chamber 2, film collection chamber 3, power unit 4, forming device 5, and film 100 into one unit. With the fixed support 9, the film tank 1 proposed in this embodiment can be easily placed at the urination area, so that whether it is the elderly, children, or female samplers, they can easily urinate in the collection area A to collect urine, which significantly enhances the user experience.

[0049] It should also be noted that sampling in self-sampling area B can be done by either extraction or filling. Extraction refers to drawing urine samples from self-sampling area B using a syringe or aspiration tube.

[0050] It should be understood that since the length of the film 100 in the film roll is relatively long, usually more than 10 meters, while the film trough 1 used for each sampler only needs to be less than 1 meter, the length of the film 100 consumed by each sampler is relatively short. Therefore, after the previous sampler finishes sampling, the used film 100 only needs to be collected into the film collection bin 3 by the power device 4. Correspondingly, the unused clean film 100 in the film release bin 2 will be driven to form a new film trough 1 for the next sampler to use.

[0051] Furthermore, in this embodiment, as Figure 3 , Figure 4 As shown, the second extension segment 53 is formed by the top of the base 51 extending upward.

[0052] It should be understood that the second extension segment 53 can be either a partial extension on one side of the base 51 or an overall extension on one side of the base 51.

[0053] That is, depending on the specific differences in the starting points of the first extension segment 52 and the second extension segment 53, the shape and structure of the base 51 can be not only the same, for example, as Figure 4 As shown, when the first extension segment 52, the second extension segment 53 and the base 51 together form a "U" shape, a part of the arc-shaped segment at the bottom can be regarded as the base 51; for example, when the first extension segment 52, the second extension segment 53 and the base 51 together form a "V" shape, the connection between the first extension segment 52 and the second extension segment 53 is the base 51.

[0054] Furthermore, in this embodiment, the height of the extended end of the second extension segment 53 is greater than the height of the extended end of the first extension segment 52.

[0055] By providing the second extension 53, the membrane 100 is prevented from shifting away from the first extension 52 under the influence of urine, thus preventing the urine from stretching the membrane 100 toward the substrate 51. Furthermore, when the height of the extension end of the second extension 53 is greater than the height of the extension end of the first extension 52, it can also ensure that when the sampler urinates, the urine causes minimal deformation of the membrane 100 in the collection area A toward the substrate 51.

[0056] It should be understood that, in this embodiment, height refers to the distance between the corresponding position of the membrane tank 1 and the ground after it is installed.

[0057] Furthermore, in order to ensure that the film 100 located in the area of ​​the forming device 5 forms a "U" shape and / or a "V" shape to ensure that the film groove 1 can be formed, the upper surface of the first extension 52 is preferably curved, or the upper surface of the first extension 52 is inclined, or a portion of the upper surface of the first extension 52 is curved and a portion is planar.

[0058] It should be noted that the upper surface of the first extension segment 52 is curved, meaning that the geometry of the upper surface corresponding to the cross-section of the first extension segment 52 along the length of the membrane groove 1 is arc-shaped; correspondingly, when the upper surface of the first extension segment 52 is inclined, the geometry of the upper surface corresponding to the cross-section of the first extension segment 52 is a straight line, and forms a non-zero angle with the horizontal line.

[0059] It should be understood that the angle between the straight line corresponding to the plane and the horizontal plane in the cross section of the first extension segment 52 can also be zero only when the upper surface of the first extension segment 52 is partly curved and partly planar.

[0060] Furthermore, such as Figure 3 As shown, since the membrane roll usually has a mandrel, the membrane tank 1 for collecting urine proposed in this application also includes a support rod 6. The support rod 6 is located inside the membrane placement chamber 2, and the membrane roll is sleeved on the support rod 6. By setting the support rod 6, it is only necessary to insert the support rod 6 into the mandrel for fixation.

[0061] It should be understood that although this application describes the presence of a support rod 6, it should also be understood that the membrane placement chamber 2 may not have a support rod 6, and the membrane roll may be placed directly in the membrane placement chamber 2, which can also achieve the membrane trough 1 proposed in this application.

[0062] Furthermore, to ensure that the film 100 located between the film dispensing chamber 2 and the film receiving chamber 3 is in a taut state, such as... Figure 3 As shown, the membrane tank 1 for collecting urine proposed in this application further includes a damping element 7, which is disposed between the membrane dispensing chamber 2 and the membrane roll; wherein, the damping element 7 is disposed between the membrane dispensing chamber 2 and the membrane roll in at least three ways:

[0063] In the first embodiment of this application, one end of the damping member 7 is directly connected to the film-dispensing chamber 2, and the other end is connected to the support rod 6. When the film roll has a mandrel and is sleeved on the support rod 6, the support rod 6 and the mandrel are relatively fixed. At this time, the rotation of the film roll will drive the support rod 6 to rotate relative to the film-dispensing chamber 2. Under the action of the damping member 7, a certain resistance is provided to the rotation of the support rod 6, that is, a certain resistance is provided to the rotation of the film roll, ensuring that the film 100 located between the film-dispensing chamber 2 and the film-receiving chamber 3 is in a taut state.

[0064] In the second embodiment of this application, the support rod 6 is rotatably connected to the film feeding chamber 2. One end of the damping member 7 is connected to the film feeding chamber 2, and the other end can be connected to either the support rod 6 or the mandrel of the film roll. This also ensures that the film 100 located between the film feeding chamber 2 and the film receiving chamber 3 is in a taut state.

[0065] Thirdly, as another embodiment of this application, without the support rod 6, one end of the damping member 7 is disposed on the inner circumferential surface of the film dispensing chamber 2, and the other end abuts against the outer circumferential surface of the film roll, so that the outer circumferential surface of the film roll and the inner circumferential surface of the film dispensing chamber 2 are in contact. By using the damping member 7 to abut against the outer circumferential surface of the film roll, the friction between the film roll and the inner circumferential surface of the film dispensing chamber 2 is increased, which can also ensure that the film 100 located between the film dispensing chamber 2 and the film receiving chamber 3 is in a taut state.

[0066] Furthermore, during use, in order to protect the cleanliness of the membrane roll in the membrane placement chamber 2 and prevent urine from flowing into the membrane placement chamber 2, the height of the membrane placement chamber 2 is greater than the height of the membrane collection chamber 3. At this time, the membrane groove 1 formed between the membrane placement chamber 2 and the membrane collection chamber 3 is also inclined, that is, the height of the membrane groove 1 on the side closer to the membrane placement chamber 2 is greater than the height of the membrane groove 1 on the side closer to the membrane collection chamber 3, so that the urine flows towards the membrane collection chamber 3, thereby ensuring that the membrane roll in the membrane placement chamber 2 will not be contaminated by the sampler's urine.

[0067] It should be understood that the length of the membrane groove 1 may vary depending on the actual space in which it is installed. Similarly, the dimensions of the forming device 5 in the length direction of the membrane groove 1 may also vary. That is, the forming device 5 proposed in this application may extend along the length direction of the membrane groove 1.

[0068] Correspondingly, as the molding device 5 extends, it may pose certain obstacles during installation and use, such as hindering the sampler from standing or squatting. Therefore, in this embodiment, the number of molding devices 5 is preferably two, and the optimal setting is the spacing between the two molding devices 5.

[0069] Furthermore, in this embodiment, the film 100 can either directly cover the end of the first extension 52 to form a membrane groove 1, or it can form a membrane groove 1 only under the action of the upper surface of the first extension 52. When the film 100 forms a membrane groove 1 only under the action of the upper surface of the first extension 52, the membrane groove 1 for collecting urine proposed in this application also includes a pressure sheet 8. The pressure sheet 8 includes a snap-fit ​​portion 81 and an extension portion 82. The snap-fit ​​portion 81 is provided with a snap-fit ​​interface adapted to the extension end of the first extension 52. The pressure sheet 8 is snapped onto the first extension 52 through the snap-fit ​​interface. The film 100 forming the membrane groove 1 is slidably connected to the lower surface of the extension portion 82.

[0070] It should be understood that the sliding connection between the thin film 100 constituting the membrane groove 1 and the lower surface of the extension 82 means that a gap is formed between the extension 82 of the pressure diaphragm 8 and the upper surface of the first extension 52, which only allows the thin film 100 to slide along the length direction of the membrane groove 1. When the power device 4 drives the thin film 100 to move toward the film receiving chamber 3, the thin film 100 slides through the gap between the extension 82 and the first extension 52, that is, the thin film 100 and the lower surface of the extension 82 are slidably connected.

[0071] As a second aspect of this embodiment, such as Figures 1 to 3 As shown, a forming mechanism 200 for a membrane tank 1 for collecting urine is configured to form the membrane tank 1 as described above.

[0072] As a third aspect of this embodiment, such as Figures 1 to 4 As shown, a forming device 5 for a membrane tank 1 for collecting urine is configured to form the forming mechanism 200 as described above.

[0073] The present invention discloses a membrane tank 1, a forming mechanism 200, and a forming device 5 for collecting urine. Its advantages are: ease of use, freeing the sampler's hands and improving the sampler's experience; and high reliability. Specifically, it is reflected in:

[0074] First, the membrane trough 1 proposed in this application is placed at the urination site. The membrane trough 1 is constructed using a disposable membrane. When collecting urine, the sampler does not need to hold the urine cup used to collect the urine, which makes it more convenient for the sampler to use and frees up the sampler's hands, thereby improving the sampler's experience. At the same time, the power device 4 is used to roll the membrane 100 that has been used by the sampler into the membrane collection chamber 3, and pull out the clean and uncontaminated membrane 100 set in the membrane placement chamber 2 to form a new membrane trough 1 for subsequent samplers to use. This ensures that the samples collected through the membrane trough 1 proposed in this application will not be cross-contaminated with samples from other samplers, thus demonstrating high reliability.

[0075] Secondly, since the membrane tank 1 proposed in this application is placed at the urination site, both the elderly and children can collect urine for sampling on their own without the assistance of others, which further enhances the sampling experience.

[0076] Furthermore, the damping element 7 ensures that the film 100 located between the film dispensing chamber 2 and the film receiving chamber 3 has a certain tension, thereby ensuring the formation of the film tank 1 and further demonstrating its high reliability.

[0077] Finally, by using the membrane pressing sheet 8, it is ensured that after each sampler collects the used portion of the film 100 into the film receiving chamber 3 via the power device 4, a new film tank 1 can be formed from the clean and uncontaminated film 100 in the film placement chamber 2, which once again demonstrates the high reliability.

[0078] In the description of this application, it should be understood that the application scenarios involved, such as "connected parts" and "pre-drilled holes", are all practically achievable by using conventional and known technical means when applying the embedded parts proposed in this embodiment; such as using a drill bit to make holes in a wooden board at a certain size.

[0079] It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0080] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0081] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0082] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
