[0001] The utility model relates to the technical field of medical consumables, in particular to a sampling swab used for skin soft tissue infection sites or open wounds. Background Art
[0002] When dermatologists or surgical medical staff examine the patient's abscess cavity (i.e., the skin soft tissue infection site) or open wound site, they need to use cotton swabs to collect secretions for testing. The cotton swab heads of commonly used cotton swabs are generally circular in structure, while the patient's abscess cavity opening or open wound opening is relatively small. The cotton swab heads of existing conventional cotton swabs have a large outer diameter and are not easy to enter the abscess cavity or wound. Using external force to squeeze the cotton swab head into the above-mentioned opening will cause the wound to expand, which is not conducive to the patient's recovery.
[0003] In addition, the cotton swab head of the existing cotton swab is generally dry, and the sampling volume when using the cotton swab head is generally small. When the outside temperature is high, the activity of the sample in the secretion cannot be guaranteed, resulting in large errors in the test results; when exploring the abscess cavity, it is often necessary to explore the depth and width of the abscess cavity, and the existing conventional cotton swabs do not have the function of measuring the depth and width of the abscess cavity.
[0004] Therefore, how to design a sampling swab that can be used for skin soft tissue infection sites or open wound sites is a technical problem that has not yet been solved in the prior art. Utility Model Content

[0031] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example 1
[0032] This embodiment provides a sampling swab for skin soft tissue infection sites or open wounds, such as Figure 1-3 As shown, it includes a sampling bottle 2 and a bottle cap 1, a rod body 3 is arranged at the bottom of the bottle cap 1, a sampling head 4 for sampling is arranged at the lower end of the rod body 3, the sampling head 4 is a flat structure, the thickness of the sampling head 4 is 1mm-3mm, the width is 5mm-10mm, and the diameter of the rod body 3 is not greater than the thickness of the sampling head 4.
[0033] A first cavity 101 is provided in the bottle cap 1, and the rod body 3 is a hollow tube structure to form a second cavity 301. The first cavity 101 and the second cavity 301 are connected to each other. A switch assembly 5 is provided on the top of the bottle cap 1. The switch assembly 5 is used to control the first cavity 101 and the second cavity 301 to be in a connected state or an isolated state. The end of the rod body 3 facing the sampling head 4 is an open structure, and the first cavity 101 is filled with physiological saline.
[0034] When the sampling swab of this embodiment is used, the medical staff first turns on the switch assembly 5, the first cavity 101 and the second cavity 301 are connected to each other, the physiological saline in the first cavity 101 flows to the sampling head 4, and after soaking the sampling head 4, the staff removes the bottle cap 1 provided with the sampling head 4 from the sampling bottle 2 to sample the secretions in the abscess cavity of the patient. After sampling the secretions, the sampling head 4 soaked with physiological saline can remain moist, and the physiological saline flowing from the first cavity 101 will also remain at the bottom of the sampling bottle 2, providing a moist environment for the sample and ensuring the biological activity of the secretions.
[0035] The switch assembly 5 is a cylindrical structure sealing plug 303, and the sealing plug 303 is installed on the bottle cap 1 along the longitudinal direction. The sealing plug 303 can move up and down on the bottle cap 1. The lower end of the sealing plug 303 matches the top opening of the second cavity 301, so that the sealing plug 303 can open or close the top opening of the second cavity 301 when moving up and down.
[0036] Furthermore, combined with the flat structure of the sampling head 4, medical staff can fully sample during the sampling process, increase the number of samples, reduce the medical staff's repeated operations, and improve the sampling efficiency.
[0037] In order to ensure that the sampling head 4 will not be contaminated before and after sampling, the sampling bottle 2 and the bottle cap 1 are connected by a threaded structure, which is convenient for medical staff to operate and minimizes the impact of the internal environment of the sampling bottle 2 on the external environment.
[0038] The sampling head 4 is made of flocked sponge, which can increase the number of samples, and the components sampled by the sampling head 4 can be fully released into the culture solution during the subsequent detection and analysis process, thereby ensuring the accuracy of the analysis test results.
[0039] In order to enable medical personnel to measure data such as the depth and width of the abscess cavity, a scale is provided on the rod body 3 , and medical personnel can accurately detect the depth and range of the abscess cavity according to the insertion depth of the rod body 3 . Example 2
[0040] This embodiment provides a sampling swab for skin soft tissue infection sites or open wounds, such as Figure 4 As shown, in this embodiment, the bottle cap 1 is provided with a first cavity 101, the rod body 3 is a columnar structure, one end of the rod body 3 is fixedly connected to the bottle cap 1, and a through hole is provided on the inner bottom wall of the bottle cap 1 forming the first cavity 101, a film is provided at the position of the through hole, and the switch component 5 is provided at the position corresponding to the film on the bottle cap 1, and the switch component 5 can be lifted and lowered on the bottle cap 1, and a protruding spike 502 is provided on one end of the switch component 5 facing the film; when the switch component 5 moves downward on the bottle cap 1, it can pierce the film, so that the physiological saline in the first cavity 101 flows into the sampling bottle 2.
[0041] Before sampling, the film at the through hole position can be punctured by the protruding spike 502 of the switch assembly 5, so that the physiological saline in the first cavity 101 can flow out into the sampling bottle 2 through the through hole; preferably, the through hole is set close to the rod body 3, and the physiological saline flowing out from the through hole position flows along the rod body 3 to the sampling head 4, which can soak the sampling head, making it convenient for medical staff to use the soaked sampling head 4 to perform sampling operations.
[0042] Furthermore, the switch assembly 5 is a cylindrical structure, and a spring 503 is provided at the upper end of the bottle cap 1 corresponding to the setting position of the switch assembly 5. The spring 503 is fixedly connected to the end of the switch assembly 5 away from the bottle cap, so that the column of the switch assembly 5 can be raised and lowered on the bottle cap 1.
[0043] In order to ensure the sealing of the first cavity 101, an elastic seal is provided at the connection position between the bottle cap 1 and the cylindrical body, so that the first cavity 101 can maintain good sealing during the lifting movement of the cylindrical body. The elastic seal of the cap can be rubber.

A switch assembly 5 is provided on the side wall of the rod body 3 close to the sampling head 4. The switch assembly 5 is a pluggable seal 501. The seal 501 is used to divide the second cavity 301 into two cavities, wherein the cavity away from the sampling head 4 is filled with physiological saline, and the rod body 3 is an open structure on the side facing the sampling head 4.
[0046] When taking samples, medical staff can pull out the sealing member 501 to release the physiological saline in the upper cavity of the second cavity 301 to the sampling head 4 , thereby soaking the sampling head 4 .
[0047] The other parts of this embodiment are the same as those of Embodiment 1 or Embodiment 2 and will not be described in detail here. Example 4
[0048] This embodiment provides a sampling swab for skin soft tissue infection sites or open wounds, which is an improvement on the basis of embodiment 2. Figure 5 As shown, a guide groove 302 extending along the length direction of the rod body 3 is provided at the position corresponding to the through hole on the rod body 3, and one end of the guide groove 302 extends to the position of the sampling head 4. According to the description in Example 2, the physiological saline flowing out through the through hole can flow evenly to the sampling head 4 through the guide groove 302, thereby achieving the effect of soaking the sampling head 4.
