[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 The utility model provides a sweat sampling device, comprising:

[0023] An outer adhesive layer 11, on which the skin contact surface is provided with a positioning groove 12;

[0024] The medical cotton layer 13 is detachably arranged in the positioning groove 12;

[0025] The anti-slip structure is arranged at the periphery of the positioning groove 12 and is used to fix the medical cotton layer 13 in the positioning groove 12 .

[0026] In this embodiment, a positioning groove 12 is set on the outer adhesive layer 11, and a medical cotton layer 13 of an appropriate size is placed in the positioning groove 12, and then an anti-falling structure is used for auxiliary fixation. This can avoid the problem of the medical cotton layer 13 easily falling off before and after use, ensure the smoothness of the sampling process, and improve the sampling efficiency.

[0027] In one embodiment, the anti-slip structure includes a pressure belt 14, one end of which is softly connected to the outer adhesive layer 11, and the other end is freely rotatable. The pressure belt 14 is turned over and pressed on the outer edge of the medical cotton layer 13 and fixed by a positioning structure.

[0028] This embodiment is configured such that after the medical cotton layer 13 is placed in the positioning groove 12, the pressing belt 14 is turned over so that the pressing belt 14 is pressed against the outer edge of the medical cotton layer 13, and then the pressing belt 14 is locked by the positioning structure so that the medical cotton layer 13 is fixed, which can avoid the problem of the medical cotton layer 13 falling off easily before and after use, ensure the smoothness of the sampling process, and improve the sampling efficiency.

[0029] Specifically, the soft connection between one end of the pressure strip 14 and the outer adhesive layer 11 can be achieved by sewing with yarn or other connection methods that can achieve the requirement of turning over the pressure strip 14.

[0030] In one embodiment, see Figure 1 The positioning structure is a convex point 15 arranged on the pressure strip, wherein a dot groove 16 adapted to the convex point 15 is arranged on the outer groove edge of the positioning groove 12.

[0031] This embodiment is configured as follows: after the medical cotton layer 13 is placed in the positioning groove 12, the pressing belt 14 is turned over. After the pressing belt 14 is attached to the medical cotton layer 13, a force is applied so that the protrusions 15 on the pressing belt 14 are connected to the point grooves 16 to form a fixed connection. After sampling, the pressing belt 14 can be pulled open using tweezers, and the operation is convenient and quick.

[0032] In one embodiment, see Figure 2 The positioning structure is a foldable pressure strip 17, which includes a first support rod 171 and a second support rod 172. The first support rod 171 and the second support rod 172 are respectively arranged on the outer adhesive layer 11 and the pressing belt 14, and the first support rod 171 and the second support rod 172 are rotatably connected through a plastic sheet. A protrusion is provided at the end of the second support rod 172, and a groove portion adapted to the protrusion is provided at the end of the first support rod 171.

[0033] This embodiment is configured such that after the medical cotton layer 13 is placed in the positioning groove 12, the pressing belt 14 is turned over. After the pressing belt 14 is attached to the medical cotton layer 13, the second support rod 172 is unfolded synchronously with the pressing belt 14 and finally connected to the end of the first support rod 171, thereby achieving the effect of fixing the medical cotton layer 13, and the operation is simple and quick.

[0034] The shape of the pressing belt 14 is not limited and can be as shown in the following figure. Figure 1 The graphics shown can also be as shown in the attached Figure 2 The rectangle shown.

[0035] In one embodiment, a heating layer 18 is provided on the skin contact surface of the outer adhesive layer 11 and is located outside the positioning groove 12 to assist in rapid sweating.

[0036] This embodiment is configured so that after the medical cotton layer 13 is attached to the skin, the skin around the medical cotton layer 13 can be quickly assisted to sweat, thereby improving the efficiency of sampling. Specifically, the heating layer can be made of materials commonly used in warm baby products on the market.

[0037] In one embodiment, the heating layer 18 is annular in structure and is bonded to the outer adhesive layer 11 , and an inner adhesive layer 19 adapted thereto is provided on the outer adhesive layer 11 .

[0038] This embodiment is configured so that the heating layer 18 can be replaced after a single sampling or a small number of samplings, which can reduce the overall cost of use and save resources.

[0039] In one embodiment, the outer adhesive layer 11 is fixed to the skin via an outer adhesive layer 20 .

[0040] The present embodiment is configured in this way. The existing sampling generally adopts a wristwatch-like wearing structure, but this structure has great limitations and cannot collect sweat from any part of the skin of the whole body. The present application adopts an external adhesive layer 20 structure to achieve fixation by bonding any part of the skin of the whole body, and sweat sampling can be performed according to demand.

[0041] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
