Description

Technical Field

[0001] The utility model relates to the technical field of children's urine collection, in particular to a disposable children's urine collection device with a connecting valve. Background Art

[0002] When conducting urine tests on children, disposable urine collection bags are generally used to collect urine. Urine contains a variety of components that reflect the health status of children. Accurate urine testing is crucial for diagnosis.

[0003] When collecting urine, urine is generally collected first through a disposable urine collection bag, and then a certain amount of urine is collected through a specimen tube. The operation process is relatively complicated. At the same time, during catheterization, urine is easily contaminated by the external environment and other factors, further affecting the purity of the urine sample and the accuracy of the test results. During the catheterization process, urine may drip or leak and cause infection on the operator's hands. In addition, most of the current urine collection bags use a bonding layer that fits the child's skin. If there is a lot of urine in the urine collection bag, it is easy to cause the bonding layer to fall off the child's skin, resulting in failure to collect urine. At the same time, it will also cause infection to the child's clothes, skin, etc. Therefore, the present application provides a disposable children's urine collection device with a connecting valve to meet the needs.

[0037] like Figures 1 to 8 As shown, the embodiment of the utility model provides a disposable urine collecting device for children with a connecting valve, comprising a urine collecting bag 1 and a specimen tube 8. The urine collecting bag 1 comprises a urine collecting bag body and an adhesive layer. This is the prior art. A blocking component is provided on the urine collecting bag 1. An installation component is connected between the blocking component and the specimen tube 8. The installation component is used to quickly assemble and disassemble the blocking component and the specimen tube 8, so that medical staff can quickly separate the specimen tube 8 from the urine collecting bag 1 when collecting urine specimens.

[0038] like Figures 4 to 8As shown, the blocking assembly includes a mounting tube 5 fixedly connected to the bottom end of the urine collecting bag, and a blocking component is provided on the mounting tube 5. The blocking component includes a mounting hole opened on the outer wall of the mounting tube 5, and a hand-tightening handle 6 is rotatably connected in the mounting hole. A closing unit 10 is rotatably connected inside the mounting tube 5, and the closing unit 10 is connected to the hand-tightening handle 6. The closing unit 10 includes a closing sphere 101, and an adsorption protrusion 103 is fixedly connected to one end of the closing sphere 101. A special-shaped flow channel 104 is opened inside the closing sphere 101, and a guide matching seat 105 is fixedly connected to the bottom end of the special-shaped flow channel 104 through a connecting rib 106. A closing plug 11 located in the mounting tube 5 is provided below the closing unit 10. The closing plug 11 includes an upper cover and a plug body. The diameter of the plug body matches the inner diameter of the specimen tube 8. The upper cover of the closing plug 11 is equidistantly provided with connecting protrusions 111 for connecting and matching with the mounting tube 5.

[0039] When it is necessary to collect a urine sample, the medical staff drives the closing sphere 101 to rotate by turning the hand-tightening handle 6, so that the upper port of the special-shaped flow channel 104 is aligned with the top flow channel of the mounting tube 5. At this time, there is a gap between the bottom end of the plug body of the closing plug 11 and the urine inlet end of the specimen tube 8, so that urine flows out of the urine collecting bag 1 and enters the specimen tube 8 through the gap between the special-shaped flow channel 104, the inner wall of the mounting tube 5, and the bottom end of the plug body and the specimen tube 8.

[0040] The medical staff drives the closed sphere 101 connected to the inside of the mounting tube 5 to rotate by manually turning the handle 6. The closed sphere 101 will rotate at a certain angle, and the adsorption protrusion 103 fixedly installed at one end of the closed sphere 101 will be rotated to the top of the specimen tube 8. The closed sphere 101 can block the top flow channel of the mounting tube 5 to prevent urine from continuously flowing from the urine collecting bag 1 into the mounting tube 5.

[0041] Specifically, during the process of rotating to the top of the specimen tube 8, the adsorption protrusion 103 will gradually come into contact with the upper cover of the sealing plug 11 by squeezing. During the process of squeezing, the adsorption protrusion 103 will adsorb the upper cover of the sealing plug 11 and the urine remaining around the sealing plug 11. At the same time, during the process of squeezing the sealing plug 11, the adsorption protrusion 103 will break the connecting protrusion 111 that connects the upper cover of the sealing plug 11 with the mounting tube, so that the sealing plug 11 moves downward.

[0042] Furthermore, when the adsorption protrusion 103 moves to a vertical state, it will squeeze the plug body of the sealing plug 11 to be completely inserted into the tube mouth of the specimen tube 8, thereby blocking the specimen tube 8. The urine around the sealing plug 11 will be squeezed to flow to the upper part of the sealing plug 11 during the process of the sealing plug 11 being pressed down, and this part of the urine will contact the adsorption protrusion 103 and then be absorbed by the adsorption protrusion 103.

[0043] In order to reduce the contact between urine and the sealing plug 11 during the flow, a special-shaped flow channel 104 is opened inside the sealing sphere 101 to guide the urine to flow in a directional manner. In addition, in order to increase the guiding effect of the special-shaped flow channel 104, a guiding matching seat 105 is provided at the bottom end of the special-shaped flow channel 104, so that the urine can flow along the diffusion-type flow channel formed by the cooperation between the special-shaped flow channel 104 and the guiding matching seat 105, and the sealing plug 11 is arranged directly below the guiding matching seat 105. The diffusion-type flow channel guides the flow of urine, which can reduce the contact between urine and the sealing plug 11, so that the urine flows into the specimen tube 8 from the channel reserved between the mounting tube 5 and the sealing plug 11.

[0044] It should be noted that before the device is used, the closing sphere 101 is preset to rotate at a certain angle, and the top flow channel of the mounting tube 5 is blocked by the ball of the closing sphere 101 to prevent urine from directly entering the specimen tube 8 during urine collection, causing the specimen tube 8 to overflow. In the subsequent separation process of the specimen tube 8, urine overflow and leakage will occur. When it is necessary to collect urine specimens, the medical staff drives the closing sphere 101 to rotate by manually twisting the handle 6, so that the top of the special-shaped flow channel 104 inside the closing sphere 101 is aligned with the internal flow channel of the mounting tube 5, forming a complete guiding flow channel.

[0045] like Figure 4 As shown, the installation component includes a plug-in groove 7 symmetrically arranged on the outer wall of the bottom end of the installation tube 5, and a plug-in seat 9 fixedly connected to the top of the specimen tube 8 is clamped in the plug-in groove 7. The plug-in groove 7 is arranged in an inverted L shape, and a clamping block that is clamped and cooperates with the plug-in groove is arranged at one end of the plug-in seat 9. When it is necessary to separate the urine collecting bag 1 and the specimen tube 8, the medical staff can separate the plug-in groove 7 and the plug-in seat 9 from each other by rotating the plug-in seat 9, thereby completing the separation of the urine collecting bag 1 and the specimen tube 8. The setting of the quick clamping mechanism is convenient for medical staff to operate.

[0046] like Figure 8 As shown, the plug body of the closure plug 11 is equidistantly fixedly connected with a closure rubber ring 12 for increasing the sealing performance between the closure plug 11 and the specimen tube 8. The setting of the closure rubber ring 12 can enable the closure plug 11 to form an interference fit with the specimen tube 8, thereby increasing the sealing performance between the closure plug 11 and the specimen tube 8 and avoiding urine leakage. In addition, the closure rubber ring 12 can increase the friction between the closure plug 11 and the specimen tube 8.

[0047] like Figures 1 to 3As shown, a mounting ring 13 is fixedly connected to the top of the urine collecting bag 1, a connecting ring 14 is sleeved inside the mounting ring 13, and a clip 15 is installed on the top of the connecting ring 14. Through the arrangement of the connecting ring 14 and the clip 15, when the device is collecting urine, the medical staff can clamp the clip 15 with the clothes of the child, thereby increasing the stability of the urine collecting bag 1 when collecting urine. In addition, in the subsequent process of collecting specimens, the urine collecting bag 1 can be suspended by the connecting ring 14 and the clip 15, and the medical staff does not need to hold it, thereby increasing the convenience of using the urine collecting bag 1 in subsequent collection and making it more convenient for medical staff to use. In addition, the connecting ring 14 and the clip 15 are made of plastic material, which can reduce the overall weight of the device.

[0048] like Figure 1 and Figure 5 As shown, the side walls of the urine collecting bag 1 and the specimen tube 8 are provided with scale lines, which can facilitate medical staff to check the collected urine volume in real time and facilitate use by medical staff.

[0049] like Figures 1 to 3 As shown, a sealing sheet 16 is installed at one end of the mounting pad 2, and one end of the sealing sheet 16 bypasses the urine collecting bag 1 and is connected to the connecting patch 17, and the connecting patch 17 is fixedly connected to the side of the urine collecting bag 1 away from the mounting pad 2. An adhesive layer is provided on one side of the sealing sheet 16, and a release paper is attached to the adhesive layer of the sealing sheet 16. Through the setting of the sealing sheet 16, after the urine collecting bag 1 completes the collection of urine, the release paper on the sealing sheet 16 can be removed, and one end of the sealing sheet 16 can be removed from the connecting patch 17, and then the connecting patch 17 can be fixedly connected to the side of the urine collecting bag 1 away from the mounting pad 2. The connecting patch 17 is fitted with the adhesive layer 3 to seal the collecting port of the urine collecting bag 1, thereby preventing urine from leaking from the collecting port at the top of the urine collecting bag 1 during subsequent use. The connecting patch 17 on one side of the urine collecting bag 1 can fit the urine collecting bag 1 to the wall through the connecting patch 17 when the urine collecting bag 1 is hung, thereby increasing the stability of the urine collecting bag 1 during subsequent use, and cooperating with the clip 15 to increase the convenience of use of the equipment. In addition, the setting of the release paper avoids contamination of the connecting patch 17, thereby ensuring better use.

[0050] The working principle of the utility model is:

[0051] When it is necessary to collect urine from the child, the medical staff removes the release paper on the adhesive layer 3, and then sticks the adhesive layer on the child's body. At the same time, the clip 15 is clamped on the child's clothes to start collecting urine. After the urine is collected, the clip 15 is removed from the clothes, and the medical staff hangs it in a specified place through the connecting ring 14. At the same time, the medical staff removes the release paper of the packaging sheet 16, and then sticks the packaging sheet 16 on the adhesive layer, and cooperates with the adhesive layer to form a closure on the collection port on the urine collection bag 1 to prevent urine from leaking from the collection port on the urine collection bag 1. In addition, the connecting patch 17 on one side of the urine collection bag 1 for fixing the packaging sheet 16 is fitted with the wall to form a restriction on the urine collection bag 1. After that, the specimen collection begins.

[0052] The medical staff drives the closed sphere 101 to rotate by turning the hand-tightening handle 6, so that the upper end of the special-shaped flow channel 104 is aligned with the top flow channel of the mounting tube 5. At this time, the urine enters the specimen tube 8 from the guide flow channel formed by the above two. The medical staff identifies the amount of urine to be collected by the scale line on the specimen tube 8. When the required amount of urine is collected, the medical staff drives the closed sphere 101 to rotate again by turning the hand-tightening handle 6. The top flow channel of the mounting tube 5 is blocked, and at the same time, the adsorption protrusion 103 at one end of the closing sphere 101 will rotate synchronously to squeeze the closing plug 11, so that the closing plug 11 blocks the specimen tube 8. At the same time, the adsorption protrusion 103 can adsorb the urine remaining in the closing plug 11. Finally, the medical staff rotates the specimen tube 8 to turn the connector 9 out of the connector slot 7 at the bottom end of the mounting tube 5, completes the separation of the urine collection bag 1 and the specimen tube 8, and then sends the specimen tube 8 for detection.

[0053] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
