Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clinical trial data acquisition technology, specifically relating to a clinical trial data acquisition device. Background Technology
[0002] When conducting clinical trials of drugs, clinical trial data needs to be collected from participants after they have taken the drug. This includes collecting sweat samples. Sweat is mainly composed of water and also contains small amounts of metabolic waste products such as sodium chloride, urea, and lactic acid. However, the proportions of these basic components in sweat vary depending on the location of the body, requiring separate collection of sweat from different areas. Currently, sweat collection pads can be used to collect sweat. However, during the sweating process and collection, sweat from the upper part of the body tends to flow downwards. When collecting sweat from the middle and lower parts of the body, sweat from the head or upper torso tends to flow downwards and mix with sweat from other areas. Sweat collected by lower sweat collection pads will contain sweat from other areas, altering the proportions of the basic components in the collected sweat and affecting the accuracy of the experimental results. Utility Model Content
[0003] This invention provides a clinical trial data acquisition device that collects purer sweat, avoiding the mixing of sweat from multiple sites that could lead to mixed sweat components and affect the accuracy of the data.
[0004] This utility model provides the following technical solution: a clinical trial data acquisition device, including a connecting plate, a sweat collection cotton pad inserted into the center of the connecting plate, a sweat barrier cotton ring fixedly connected to the inner wall of the connecting plate, a sweat pressure ring provided on the outer side of the sweat barrier cotton ring, a sweat discharge hole opened on the side wall of the sweat pressure ring, a sweat barrier inner ring provided on the outer side of the sweat collection cotton pad, and binding tape tied to the outer wall of the connecting plate.
[0005] The connecting plate has a clearance hole in the center, and the sweat collection pad is inserted into the clearance hole.
[0006] The connecting plate has a directional arrow on its outer wall, and the directional arrow points upward.
[0007] The sweat-collecting cotton pad is fixedly connected to a locking plate on one side, a sealing ring is fixedly connected to the side wall of the locking plate, and a lifting strap is fixedly connected to the outer wall of the locking plate.
[0008] The sweat-blocking cotton ring has a guide notch on its lower side wall, and the guide notch corresponds to the position of the sweat discharge hole.
[0009] The sweat-blocking cotton ring and the sweat-blocking inner ring are provided with a sweat-isolation space, and the outer side of the binding tape is glued with adhesive tape.
[0010] The bottom height of the sweat-collecting cotton pad and the sweat-blocking cotton ring is less than the bottom height of the sweat-pressure barrier ring and the inner sweat-blocking ring.
[0011] The beneficial effects of this invention are as follows: By using a connecting plate to press the sweat-blocking cotton ring, the sweat-pressure ring, and the sweat-blocking inner ring onto the surface of the person's skin, the sweat-pressure ring intercepts the flowing sweat, and the sweat-blocking cotton ring absorbs the leaked sweat, while the sweat-blocking inner ring further intercepts the sweat from the outside. This prevents sweat from other parts of the body from flowing into the corresponding position of the sweat-collecting pad, making the sweat collected by the pad purer and avoiding the mixing of sweat from multiple parts, which would affect the accuracy of the collected sweat.
[0012] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. Attached Figure Description

Adhesive fixing tape. Detailed Implementation
[0018] Please see Figure 1-Figure 4 The present invention provides the following technical solution: a clinical trial data acquisition device, including a connecting plate 1, a sweat collection cotton pad 2 inserted into the center of the connecting plate 1, a sweat barrier cotton ring 3 fixedly connected to the inner wall of the connecting plate 1, a sweat pressure ring 31 provided on the outer side of the sweat barrier cotton ring 3, a sweat discharge hole 32 opened on the side wall of the sweat pressure ring 31, a sweat barrier inner ring 4 provided on the outer side of the sweat collection cotton pad 2, and a binding tape 5 bound to the outer wall of the connecting plate 1.
[0019] In this implementation plan: The staff presses the connecting plate 1 onto the skin surface of the experimental subject, then inserts the sweat collection cotton pad 2 into the clearance hole 11 and uses binding tape 5 to bind it to the experimental subject's body. Then, adhesive fixing tape 51 is applied over the binding tape 5 and the connecting plate 1 and then adhered to the experimental subject's skin. The binding tape 5 and adhesive fixing tape 51 are used to press the connecting plate 1 together. Further, the connecting plate 1 is used to press the sweat barrier cotton ring 3, the sweat pressure barrier ring 31, and the sweat barrier inner ring 4 onto the surface of the subject's skin, above the collection position. When sweat from the affected area flows down, the sweat pressure ring 31 presses against the skin to form a barrier layer, initially intercepting the flowing sweat. The intercepted sweat flows down along the outer side of the sweat pressure ring 31. A small amount of sweat that seeps inside is absorbed by the sweat barrier cotton ring 3. The sweat discharge hole 32 allows sweat from the skin inside the sweat barrier cotton ring 3 to be discharged. The sweat barrier inner ring 4 and the sweat isolation space 41 work together to form a secondary interception of sweat on the outer side, preventing sweat from accumulating and forming a continuous sweat surface, thereby preventing the continuous sweat surface from contacting the sweat collection cotton pad 2. The sweat collection pad 2 forms an exchange channel at the corresponding location, enhancing its sweat interception effect. This prevents sweat from other parts of the body from flowing into the corresponding location of the sweat collection pad 2, ensuring that the sweat collected by the pad 2 is purer and avoiding the mixing of sweat from multiple areas, which could affect the accuracy of the collected sweat. The length of the binding tape 5 is adjusted according to the different areas of use. When the sweat collection pad 2 absorbs sweat from the torso, the binding tape 5 is cut to a longer length to wrap around the experimenter's torso. When collecting sweat from the limbs using the collection pad 2, the binding tape 5 is cut to a short length and bound to the limbs of the experimenter to prevent sweat from affecting the adhesion of the binding tape 5 to the skin, which could cause the connecting plate 1 to detach from the skin. After the sweat collection is completed, the staff removes the connecting plate 1 from the skin and removes the sweat collection pad 2 from the connecting plate 1. The sweat absorbed by the sweat collection pad 2 is extracted separately, while the sweat barrier cotton ring 3 and the sweat absorbed by the sweat barrier cotton ring 3 are disposed of as waste.
[0020] The connecting plate 1 has a clearance hole 11 in the center, and the sweat collection cotton pad 2 is inserted into the clearance hole 11. The clearance hole 11 can play a clearance role, so that the sweat collection cotton pad 2 can be installed in the connecting plate 1, and the sweat collection cotton pad 2 can be easily removed and separated from the connecting plate 1.
[0021] The outer wall of the connecting plate 1 is provided with a directional indicator arrow 12, which points upward. The directional indicator arrow 12 can serve as a prompt to the user. When the connecting plate 1 is pressed together, the arrow of the directional indicator arrow 12 points upward so that the sweat discharge hole 32 and the guide notch 33 are located below.
[0022] A locking plate 21 is fixedly connected to one side of the sweat collection pad 2. A sealing ring 22 is fixedly connected to the side wall of the locking plate 21. A lifting strap 23 is fixedly connected to the outer wall of the locking plate 21. By setting the locking plate 21 and the sealing ring 22, the sweat collection pad 2 can be supported and sealed to prevent the sweat collected in the sweat collection pad 2 from leaking out through the clearance hole 11.
[0023] The lower side wall of the sweat barrier cotton ring 3 has a guide notch 33, which corresponds to the position of the sweat discharge hole 32. By setting the guide notch 33, the sweat is guided so that the sweat can gather above the sweat discharge hole 32 and then be discharged through the sweat discharge hole 32.
[0024] A sweat-blocking cotton ring 3 and a sweat-blocking inner ring 4 are provided with a sweat-isolation space 41, and an adhesive fixing tape 51 is glued to the outside of the binding tape 5; by setting the adhesive fixing tape 51, the pressing effect on the connecting plate 1 can be increased.
[0025] The bottom height of the sweat-collecting cotton pad 2 and the sweat-blocking cotton ring 3 is less than the bottom height of the sweat-blocking ring 31 and the inner sweat-blocking ring 4; the height of the sweat-collecting cotton pad 2 and the sweat-blocking cotton ring 3 is even lower, so that the sweat-collecting cotton pad 2 and the sweat-blocking cotton ring 3 can fit against the skin of the test subject when pressed together, so as to absorb sweat.
[0026] The working principle and usage process of this utility model are as follows: The operator presses the connecting plate 1 onto the skin surface of the test subject, then inserts the sweat collection cotton pad 2 into the clearance hole 11 and uses binding tape 5 to bind it to the test subject's body. Then, adhesive fixing tape 51 is applied over the binding tape 5 and the connecting plate 1 and adhered to the test subject's skin. The binding tape 5 and adhesive fixing tape 51 are used to press the connecting plate 1 together. Further, the connecting plate 1 is used to press the sweat blocking cotton ring 3, the sweat pressure blocking ring 31, and the sweat blocking inner ring 4 onto the skin surface. When sweat generated above the collection position flows downwards, the sweat pressure blocking ring 31 presses against the skin to form a barrier layer, first intercepting the flowing sweat. The intercepted sweat then flows... As sweat flows downwards along the outer side of the sweat barrier ring 31, a small amount of sweat that seeps into the interior is absorbed by the sweat barrier cotton ring 3. Sweat leaks downwards from inside the sweat barrier cotton ring 3. When excessive sweat is absorbed inside the sweat barrier cotton ring 3, the sweat drips downwards through the sweat discharge hole 32, maintaining the absorption capacity of the sweat barrier cotton ring 3. The sweat barrier inner ring 4 and the sweat isolation space 41 work together to form a secondary interception of sweat on the outer side, preventing sweat from accumulating and forming a continuous sweat surface. This prevents the continuous sweat surface from forming an exchange channel with the sweat at the corresponding position of the sweat collection cotton pad 2, enhancing the interception effect of sweat. This ensures that sweat from other parts of the body does not flow into the corresponding position of the sweat collection cotton pad 2, making the sweat collected by the sweat collection cotton pad 2 purer.
