Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a sampling device for sputum detection. Background Technology

[0002] In the diagnosis of tuberculosis, patients need to provide sputum samples. Currently, patients are provided with sampling containers, and they spit their sputum into the containers themselves. Although this method is convenient, the sputum can easily contaminate the sampling containers during self-sampling, putting healthcare workers at risk of infection. Furthermore, because the opening of the sampling containers is small, when patients spit out sputum, bacteria in the sputum are exposed to the air, contaminating the environment and increasing the risk of disease transmission. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a sampling device for sputum detection that avoids sputum exposure to air during the sampling process, ensuring the health of surrounding personnel and medical staff.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A sputum sampling device includes a sputum catheter, a guide cover, and a collection bottle. A guide tube is connected to the side of one end of the sputum catheter. One end of the guide tube is fixedly connected to the sputum catheter, and the other end is conductively connected to the guide cover. The guide cover has a trumpet-shaped structure, and the discharge end of the guide cover is fixedly connected to the guide tube. A sealing cap is provided at the inlet end of the guide cover. One side of the sealing cap is connected to the guide cover through a connector, and the sealing cap can cover the inlet end of the guide cover to seal the inlet end of the guide cover.

[0006] The sputum catheter has a closed structure at one end and a tube opening at the other end. The collection bottle has a bottle opening at one end, and the bottle opening is threadedly connected to the tube opening so that the sputum catheter can communicate with the collection bottle. The collection bottle has a bottle cap, and one side of the bottle cap is connected to the bottle opening through a first connecting strap. After the bottle opening is separated from the tube opening, the bottle cap can be placed on the bottle opening to seal the bottle opening.

[0007] A negative pressure mechanism is detachably connected to one side of the sputum catheter. The negative pressure mechanism can generate negative pressure on the sputum catheter to guide the sputum in the guide cover to the sputum catheter, and the sputum in the sputum catheter falls into the collection bottle under the action of gravity.

[0008] Furthermore, the sputum catheter is provided with a tube cap, one side of which is connected to the sputum catheter via a second connecting strap. After the bottle mouth is separated from the tube mouth, the tube cap can be placed on the tube mouth to seal the tube mouth.

[0009] Furthermore, a valve check valve is provided inside the sputum catheter. The discharge end of the valve check valve is fixedly connected to the sputum catheter and communicates with the negative pressure mechanism. Under negative pressure, the gas in the sputum catheter moves along the direction from the sputum catheter to the negative pressure mechanism.

[0010] Furthermore, the side wall of the sputum catheter is provided with a connecting tube, which has an open structure at both ends, with one end of the connecting tube communicating with the sputum catheter and the other end connected to the negative pressure mechanism;

[0011] The negative pressure mechanism includes a negative pressure cylinder, a rubber piston, and a drive rod. One end of the negative pressure cylinder is threaded into the connecting pipe, and the negative pressure cylinder is connected to the sputum catheter.

[0012] The rubber piston is disposed inside the negative pressure cylinder and is slidably connected to the inner wall of the negative pressure cylinder. One end of the drive rod is fixedly connected to the side of the rubber piston facing away from the connecting pipe, and the other end of the drive rod extends out of the negative pressure cylinder and is fixedly provided with a handle.

[0013] A one-way valve is provided at one end of the negative pressure cylinder near the connecting pipe. When the rubber piston moves toward the connecting pipe, the gas in the negative pressure cylinder is discharged through the one-way valve; when the rubber piston moves away from the connecting pipe, negative pressure is generated in the sputum catheter.

[0014] Furthermore, a bacterial filter is fixedly installed on the side of the one-way valve away from the negative pressure cylinder, and the bacterial filter is fixedly connected to the one-way valve.

[0015] Furthermore, the end of the one-way valve furthest from the bacterial filter is threadedly connected to the negative pressure cylinder.

[0016] Furthermore, the sputum catheter is made of a transparent material.

[0017] The beneficial effects of this utility model are:

[0018] 1. The patient spits sputum into the guide tube, then the sealing cap is closed. Under the action of the negative pressure mechanism, the sputum catheter generates negative pressure, and the sputum flows along the guide tube and guide cover into the sputum catheter. Then, under the action of gravity, the sputum falls into the collection bottle, thus collecting the sputum sample. After the sputum falls into the collection bottle, the sputum catheter is rotated and removed from the collection bottle. The bottle cap is then placed on the bottle opening, and the sputum sample can be sent for testing. This utility model ensures that the sputum is not directly exposed to the air during the patient's self-sampling process, reducing the risk of sputum contamination to the environment. At the same time, it ensures that the sputum does not contaminate the outer wall of the collection bottle, avoiding the risk of exposure to pathogens for medical personnel during transportation and testing.

[0019] 2. After sputum sampling is completed, place the tube cap on the tube opening to seal it. Since the sealing cap closes the inlet of the guide cover, the valve check valve is in the closed state, which keeps the sputum catheter in a closed state, preventing the sputum catheter from spreading into the environment, avoiding the contamination of the environment by germs, and ensuring the health of the surrounding people.

[0026] Please also see Figure 1 and Figure 2 A preferred embodiment of the present invention provides a sputum sampling device for sputum detection, comprising a sputum catheter 1, a guide cover 2, and a collection bottle 3.

[0027] A guide tube 11 is connected to one side of the sputum catheter 1. One end of the guide tube 11 is fixedly connected to the sputum catheter 1, and the other end is conductively connected to the guide cover 2. The guide cover 2 has a trumpet-shaped structure, and its discharge end is fixedly connected to the guide tube 11. A sealing cap 21 is provided at the inlet end of the guide cover 2. One side of the sealing cap 21 is connected to the guide cover 2 via a connector 211, and the sealing cap 21 can cover the inlet end of the guide cover 2 to seal it. In this embodiment, the connector 211 is made of soft plastic, and the sealing cap 21 has a raised ring that can be embedded into the guide cover 2 to achieve a seal at the inlet end of the guide cover 2.

[0028] The catheter 1 has a closed structure at one end and a port 101 at the other end. The collection bottle 3 has a bottle opening 301 at one end, which is threadedly connected to the port 101 to allow the catheter 1 to communicate with the collection bottle 3. The collection bottle 3 is equipped with a bottle cap 31, one side of which is connected to the bottle opening 301 via a first connecting strap 311. After the bottle opening 301 is separated from the port 101, the bottle cap 31 can be placed on the bottle opening 301 to seal it. In this embodiment, the bottle opening 301 is fitted with a first connecting ring. One end of the first connecting strap 311 is fixedly connected to the first connecting ring, and the other end is fixedly connected to the bottle cap 31. The outer wall of the bottle cap 31 is provided with several sealing rings. One end of the bottle cap 31 can be inserted into the bottle opening 301, and the sealing rings abut against the inner wall of the bottle opening to achieve a seal between the bottle cap 31 and the bottle opening 301.

[0029] A negative pressure mechanism is detachably connected to one side of the sputum catheter 1. The negative pressure mechanism can generate negative pressure on the sputum catheter 1 to guide the sputum in the guide cover 2 to the sputum catheter 1, and the sputum in the sputum catheter 1 falls into the collection bottle 3 under the action of gravity.

[0030] In this embodiment, the patient spits sputum into the guide cover 2, and then closes the sealing cap 21. Under the action of the negative pressure mechanism, the sputum catheter 1 generates negative pressure, and the sputum enters the sputum catheter 1 along the guide cover 2 and the guide tube 11. Then, under the action of its own gravity, the sputum falls into the collection bottle 3, thereby collecting and sampling the sputum. After the sputum falls into the collection bottle 3, the sputum catheter 1 is rotated and the sputum catheter 1 is removed from the collection bottle 3. The bottle cap 31 is placed on the bottle mouth 301, and the sputum sample can be sent for testing.

[0031] In this embodiment, during the patient's self-sampling process, the sputum will not be directly exposed to the air, reducing the risk of sputum contamination of the environment. At the same time, it can ensure that the sputum will not contaminate the outer wall of the collection bottle 3, avoiding the risk of medical staff being exposed to pathogens during transportation and testing.

[0032] In this embodiment, the sputum catheter 1 is made of transparent material. The transparent material of the sputum catheter 1 can penetrate the location of the sputum, so that the patient can confirm whether the sputum has fallen into the collection bottle 3.

[0033] like Figure 2 As shown, a connecting tube 13 is provided on the side wall of the sputum catheter 1. The connecting tube 13 has an open structure at both ends, and one end of the connecting tube 13 is connected to the sputum catheter 1, while the other end is connected to the negative pressure mechanism.

[0034] The negative pressure mechanism includes a negative pressure cylinder 4, a rubber piston 41, and a drive rod 42. One end of the negative pressure cylinder 4 is threaded into the connecting pipe 13, and the negative pressure cylinder 4 is connected to the sputum catheter 1.

[0035] The rubber piston 41 is installed inside the negative pressure cylinder 4 and is slidably connected to the inner wall of the negative pressure cylinder 4. One end of the drive rod 42 is fixedly connected to the side of the rubber piston 41 facing away from the connecting pipe 13, and the other end of the drive rod 42 extends out to the outside of the negative pressure cylinder 4 and is fixedly provided with a handle 43.

[0036] A one-way valve 44 is provided at one end of the negative pressure cylinder 4 near the connecting pipe 13. When the rubber piston 41 moves toward the connecting pipe 13, the gas in the negative pressure cylinder 4 is discharged through the one-way valve 44. When the rubber piston 41 moves away from the connecting pipe 13, negative pressure is generated in the sputum catheter 1.

[0037] In this embodiment, the one-way valve 44 is in the direction of the rubber piston 41 moving toward the negative pressure cylinder 4. After the sealing cap 21 closes the inlet end of the guide cover 2, the handle 43 is pulled, and the rubber piston 41 moves away from the connecting pipe 13, so that negative pressure is generated in the sputum catheter 1. Under the action of negative pressure, the sputum in the guide cover 2 can enter the guide tube 11 from the guide cover 2. Pushing the handle 43, the rubber piston 41 moves toward the connecting pipe 13, and the gas in the negative pressure cylinder 4 is discharged through the one-way valve 44, so as not to affect the guidance of sputum. The reciprocating push and pull drives the handle 43 to drive the rubber piston 41, and the sputum in the guide tube 11 can enter the sputum catheter 1. Then, the sputum falls into the collection bottle 3 under the action of its own gravity.

[0038] like Figure 2 As shown, a bacterial filter 5 is fixedly installed on the side of the one-way valve 44 away from the negative pressure cylinder 4, and the bacterial filter 5 is fixedly connected to the one-way valve 44. Under the action of the bacterial filter 5, bacteria in the negative pressure cylinder 4 can be filtered out, thereby expelling the gas and preventing bacterial contamination of the environment.

[0039] like Figure 2 As shown, the end of the one-way valve 44 furthest from the bacterial filter 5 is threadedly connected to the negative pressure cylinder 4. After sampling is completed, the one-way valve 44 is removed and discarded. After cleaning and disinfecting the negative pressure mechanism, it can be reused, reducing resource waste and alleviating the economic burden on patients.

[0040] In this embodiment, the sputum catheter 1 is provided with a tube cap 12. One side of the tube cap 12 is connected to the sputum catheter 1 via a second connecting strap 121. After the bottle mouth 301 is separated from the tube mouth 101, the tube cap 12 can be placed on the tube mouth 101 to seal the tube mouth 101. In this embodiment, the sputum catheter 1 is fitted with a second connecting ring. One end of the second connecting strap 121 is fixedly connected to the second connecting ring, and the other end is fixedly connected to the tube cap 12. The outer wall of the tube cap 12 is provided with a plurality of sealing rubber rings. One end of the tube cap 12 can be embedded into the sputum catheter 1, and the sealing rubber rings abut against the inner wall of the sputum catheter 1 to achieve the sealing of the opening of the sputum catheter 1 by the tube cap 12.

[0041] A check valve 6 is installed inside the sputum catheter 1. The discharge end of the check valve 6 is fixedly connected to the sputum catheter 1 and communicates with the negative pressure mechanism. Under negative pressure, the gas in the sputum catheter 1 moves along the direction from the sputum catheter 1 to the negative pressure mechanism. In this embodiment, the check valve 6 is made of rubber, and the check valve 6 is aligned with the connecting pipe 13.

[0042] After sputum sampling is completed, the tube cap 12 is placed on the tube opening 101 to seal it. Since the sealing cap 21 closes the inlet end of the guide cover 2, the valve check valve 6 is in a closed state, keeping the sputum catheter 1 closed. This prevents the sputum catheter 1 from leaking into the environment, avoiding bacterial contamination, and ensuring the health of surrounding personnel. The closed end of the valve check valve 6 is located near the negative pressure mechanism to prevent interference with the negative pressure mechanism's generation of negative pressure on the sputum catheter 1.

[0043] The sampling process of the sputum detection sampling device in this embodiment is as follows:

[0044] The patient spits sputum into the guide cover 2, then closes the sealing cap 21, and pushes and pulls the handle 43 to drive the rubber piston 41. When the rubber piston 41 moves away from the connecting tube 13, a negative pressure is generated in the sputum catheter 1. Under the action of negative pressure, the sputum in the guide cover 2 can enter the guide tube 11. When the rubber piston 41 moves closer to the connecting tube 13, the gas in the negative pressure cylinder 4 is discharged through the one-way valve 44, thus not affecting the sputum guidance. The sputum in the guide tube 11 can enter the sputum catheter 1, and then the sputum slides down into the collection bottle 3 under its own gravity.

[0045] After the sputum falls into the collection bottle 3, rotate the sputum catheter 1 and remove the sputum catheter 1 from the collection bottle 3. Then, put the bottle cap 31 on the bottle mouth 301 and the sputum sample can be sent for testing.

[0046] Cover the tube opening 101 with the tube cap 12 to seal the tube opening 101. Then remove the negative pressure cylinder 4 from the sputum catheter 1 and discard the sputum catheter 1. Remove the one-way valve 44 from the negative pressure cylinder 4 and discard the one-way valve 44 and the bacterial filter 5. After cleaning and disinfecting the negative pressure mechanism, the negative pressure mechanism can be reused.
