[0046] See also Figures 1 to 5 A sampling device comprises: a sampling rod 1, a first sleeve 2, a second sleeve 3 and a third sleeve 4; the first sleeve 2 and the second sleeve 3 are arranged at intervals; the sampling rod 1 passes through the first sleeve 2 and the second sleeve 3, and both ends of the sampling rod 1 extend to the outside of the first sleeve 2 and the second sleeve 3; the sampling rod 1 is slidably connected to the first sleeve 2 and the second sleeve 3; the sampling rod 1 is provided with a sampling part 5 at one end of the sampling rod 1 close to the first sleeve 2, and the other end of the sampling rod 1 away from the sampling part 5 is connected to the third sleeve 4.

[0047] Specifically, the sampling part 5 is absorbent cotton.

[0048] The sampling part 5 is a material capable of sampling cells, such as cotton. The sampling part 5 is placed at a location where sampling is required, and the cells are adsorbed on the water-washed cotton by utilizing the water-absorbing property of the sampling part 5.

[0049] Specifically, the connecting end of the third sleeve 4 and the sampling rod 1 is sealed, and the other end of the third sleeve 4 is an oblique opening 41; after the third sleeve 4 is separated from the sampling rod 1, the end of the first sleeve 2 away from the second sleeve 3 is inserted through the oblique opening 41 of the third sleeve 4, and the first sleeve 2 and the third sleeve 4 are interference fit.

[0050] The connection between the third sleeve 4 and the sampling rod 1 can adopt an easily breakable structure, such as the method of reducing the axial cross-sectional diameter of the sampling rod used in the prior art sampling rod, thereby reducing the force required to break the third sleeve 4 and the sampling rod 1.

[0051] The sampling rod 1 is made of an existing sampling rod or a sampling rod which is easy to break.

[0052] The design of the oblique opening 41 of the third sleeve 4 can play a good docking role when the third sleeve 4 is plugged into the first sleeve 2, thereby improving the efficiency of the plugging.

[0053] The third sleeve 4 and the first sleeve 2 are interference-fitted to reduce the gap after insertion, or to achieve a sealing effect, thereby ensuring the experimental effect of the sample.

[0054] The first sleeve 2 is overlapped at the oblique opening 41 of the third sleeve 4 and then plugged in during relative movement to avoid docking of the two circular cross sections of the first sleeve 2 and the third sleeve 4, which would result in the inability to complete docking in one go and waste time.

[0055] Specifically, an anti-slip layer is provided on the outer wall of the second sleeve 3 ; the second sleeve 3 and the sampling rod 1 are clearance-matched.

[0056] The outer wall of the second sleeve 3 is provided with an anti-slip layer for medical staff to hold it conveniently. The second sleeve 3 and the sampling rod 1 are clearance-matched to facilitate the axial movement of the sampling rod 1 along the second sleeve 3.

[0057] The function of the second sleeve 3 is that, when the medical staff holds the second sleeve 3 and completes sampling, the second sleeve 3 abuts against the first sleeve 2 when pulling the sampling stick 1, so that the sampling part 5 can enter the first sleeve 2. If the second sleeve 3 is not provided, the staff needs to take the sampling stick 1 out of the mouth, hold the first sleeve 2, and pull the sampling stick 1. In this case, the medical staff's hands will come into contact with the first sleeve 2. In addition, after the sampling stick 1 is taken out of the mouth, it is inevitable that it will be contaminated with other liquids in the mouth.

[0058] The second sleeve 3 can ensure that the sampling portion 5 is retracted into the first sleeve 2 in the oral cavity.

[0059] Specifically, the first sleeve 2 is provided with two inner diameters; wherein, the inner diameter of one end of the first sleeve 2 close to the sampling portion 5 is slightly larger than the outer diameter of the sampling portion 5, the outer diameter of the sampling portion 5 is the outer diameter along the axial section of the sampling rod 1, and the length of the first sleeve 2 with this inner diameter is greater than the length of the sampling portion 5; the other inner diameter of the first sleeve 2 is slightly larger than the outer diameter of the sampling rod 1, and the first sleeve 2 with this inner diameter is interference fit with the sampling rod 1.

[0060] Since the first sleeve 2 needs to be able to retract the sampling portion 5 therein, the inner diameter at the retracted end needs to be larger than the inner diameter at the end connected to the sampling rod 1 .

[0061] After the sampling portion 5 is retracted into the first sleeve 2 , the portion with a larger inner diameter of the first sleeve 2 must ensure that the sampling portion 5 can completely enter the first sleeve 2 .

[0062] The connection between the sampling rod 1 and the first sleeve 2 adopts an interference fit structure, which can increase the airtightness between them.

[0063] In order to increase the airtightness between the sampling rod 1 and the first sleeve 2, the interference friction coefficient can be increased at the sliding connection between the sampling rod 1 and the first sleeve 2 to improve the airtightness.

[0064] After the sampling part 5 is placed in the first sleeve 2, the sampling stick 1 is taken out of the oral cavity.

[0065] Specifically, the second sleeve 3 is fixed, and when the sampling rod 1 moves toward the third sleeve 4 , the sampling portion 5 enters into the first sleeve 2 .

[0066] The medical staff pulls the sampling stick 1 away from the oral cavity by hand, and the second sleeve 3 needs to be held and fixed. The first sleeve 2 will first move toward the second sleeve 3, and the second sleeve 3 will limit the first sleeve 2. When the first sleeve 2 can no longer move, the friction between the first sleeve 2 and the sampling stick 1 is less than the pulling force, and the sampling stick 1 continues to move away from the oral cavity, and the sampling part 5 will be pulled into the first sleeve 2.

[0067] A sampling device also includes a sampling box 6; a plurality of grooves 7 are evenly arranged on the sampling box 6; a combined sleeve formed by the third sleeve 4 sleeved on the first sleeve 2 is placed in the groove 7; a pressure sensor 8 is provided at the bottom of the groove 7, and the pressure sensor 8 is connected to the control system.

[0068] A plurality of grooves 7 are arranged at intervals, and the grooves 7 are grooves with a certain elasticity, into which a combined sleeve formed by combining the third sleeve 4 and the first sleeve 2 can be placed, and because the grooves 7 have a certain elasticity, they have a certain limiting effect on the combined sleeve.

[0069] When inserting the combined sleeve, it is necessary to use appropriate force to press down the combined sleeve so that the pressure sensor 8 provided at the bottom of the groove 7 can receive a signal, thereby enabling the control system to work.

[0070] Specifically, the control system includes:

[0071] A recording module is used to receive the signal from the pressure sensor 8 and can record audio; when the recording module starts recording, the medical staff can read out the number and the personal information of the sampler.

[0072] A recording conversion module is used to convert the recording content of the recording module into text; the recording conversion module converts the recording content into text to facilitate viewing using a computer in the hospital.

[0073] A storage module used to store converted text and recording content; the storage module is used to store data to facilitate subsequent calls.

[0074] Delay module used to control the working time of the recording module.

[0075] The delay module counts down when the recording module starts working. Generally, it is set to 5 seconds. Within 5 seconds, the medical staff enters the patient's information. After completion, the recording module automatically turns off. No manual control is required by the staff.

[0076] If the information entry is not completed within 5 seconds, the combined sleeve can be taken out and put back in for recording.

[0077] Specifically, an end cover 9 is provided above the sampling placement box 6, and the end cover 9 is transparent UV-proof glass.

[0078] Since sometimes the collection needs to be carried out outdoors, the sunlight will carry ultraviolet rays. In order to avoid the sample losing the test function due to external rays, the sampling box 6 is covered with transparent ultraviolet-proof glass, which is convenient for observation on the one hand and blocks ultraviolet rays on the other.

[0079] A method for using a sampling device comprises the following steps:

[0080] Step 1: tear open the packaging of the sampling stick 1, take out the sampling stick 1, insert the sampling part 5 provided at one end of the sampling stick 1 deep into the oral cavity, and place it at the desired location in the oral cavity of the human body where the sample is to be collected, and rotate it so that the sampling part 5 collects the sample;

[0081] Step 2: After collecting the oral sample, the medical staff fixes the second sleeve 3 with one hand and pulls the sampling stick 1 in the direction away from the human oral cavity, so that the first sleeve 2 moves toward the second sleeve 3, reaches the second sleeve 3, and hits the end of the second sleeve 3 and cannot move further. The sampling stick 1 is continued to be pulled so that the sampling part 5 at one end of the sampling stick 1 continues to move, and then enters the first sleeve 2;

[0082] Step 3: The medical staff takes out the sampling stick 1 in the oral cavity;

[0083] Step 4: Break off the connection between the third sleeve 4 and the sampling rod 1;

[0084] Step 5: Place the first sleeve 2 on the oblique opening 41 of the third sleeve 4 and insert it into the third sleeve 4 so that the open end of the first sleeve 2 is sealed by the third sleeve 4, which can avoid or reduce the influence of the outside world on the sample.

[0085] Step 6: Place the combined sleeve into the groove 7 on the sampling placement box 6;

[0086] Step 7: When the combined sleeve is placed in the groove 7, the combined sleeve is pressed down with appropriate force, and the pressure sensor 8 in the groove 7 is triggered, and the recording module connected to the pressure sensor 8 works;

[0087] Step 8: The recording module records the patient information read out by the medical staff, and then converts the recording into text through the recording conversion module;

[0088] Step 9: Store the text and recording in the storage module at the same time to facilitate subsequent work;

[0089] Step 10: Cover the end cover 9 on the sampling box 6 to complete the sampling.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
