Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and in particular to a nasal swab collection device and collection method. Background Technology

[0002] Following a radiation emergency, rapid and accurate detection of the type and dose of radioactive material on personnel at the scene is a crucial aspect of emergency medical rescue efforts. The collection and analysis of biological samples at nuclear rescue sites, especially nasal swabs, is a primary basis for accurately identifying the type of radioactive material, rapidly estimating the level of inhalation, and enabling early medical intervention. Unlike conventional testing methods such as urine and stool analysis, which often have a significant time lag (>24 hours), nasal swab analysis can achieve qualitative detection of internal radioactive contamination within as little as 15 minutes, offering high timeliness and convenience, ensuring that those exposed to radiation at the scene receive timely and effective medical treatment.

[0003] Because there may be cases where one nasal cavity does not inhale or inhales only a small amount, it is necessary to collect samples from both nasal cavities when collecting biological samples.

[0004] Currently, when a radiation emergency occurs, there are many people on site who need to be sampled, and rapid sampling is required. Biological samples are mostly collected manually through nasal swabs. However, since biological samples need to be collected from both nasal cavities, manually collecting samples from each nasal cavity separately is inefficient. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a nasal swab collection device and collection method to solve the problem that the existing technology of manually collecting swabs from two nasal cavities separately is slow.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A nasal swab collection device, comprising:

[0008] support;

[0009] A collection tube includes a tube body, a tube cap, and a nasal swab, wherein the nasal swab is fixedly connected to the tube cap, and the tube cap is threadedly connected to the tube body;

[0010] Two identical fixing components are rotatably mounted on a bracket and arranged in parallel with each other. The fixing components are used to fix the tube cap.

[0011] A drive assembly, mounted on the bracket, is connected in a transmission manner to the two fixed assemblies and is used to drive the two fixed assemblies to rotate.

[0012] When the two nasal swabs are inserted into the nasal cavities on both sides, the drive assembly rotates the two nasal swabs through two fixing components.

[0013] By designing the above structure, two nasal swabs can be operated simultaneously to collect biological samples from both nasal cavities. During nasal sample collection, the drive assembly can rotate the swab by driving the cap, effectively improving collection efficiency while ensuring collection quality. Furthermore, when the collection tube cannot rotate, the drive assembly can simultaneously rotate both caps, allowing it to tighten both caps onto the two collection tubes in one operation, or unscrew both caps from the two collection tubes in one operation.

[0014] Furthermore, the drive assembly includes a drive plate, a ball nut assembly, and a lead screw. The drive plate is slidably mounted on the bracket along the length of the bracket. Both ball nut assemblies are fixedly connected to the drive plate. Both lead screws are rotatably mounted on the bracket. The ball nut assemblies are threadedly connected to the lead screws. The two fixing assemblies are respectively connected to the two lead screws for transmission.

[0015] By setting up the above structure, simply changing the distance between the drive plate and the bracket will drive the fixed component to rotate through the ball nut assembly and the lead screw. Furthermore, controlling the increase or decrease of the distance can change the rotation direction of the fixed component, making the operation simple and quick.

[0016] Furthermore, one end of the lead screw is rotatably connected to the bracket, and the other end is provided with a limit ring. The limit ring cooperates with the bracket to limit the movement range of the drive plate. A compression spring is provided between the drive plate and the bracket. One end of the compression spring abuts against the bracket, and the other end abuts against the drive plate.

[0017] By setting up the above structure, during use, it is only necessary to control the distance between the drive board and the bracket to decrease. When it is necessary to increase the distance, the pressure is reduced and the spring is compressed, which will automatically reset the distance between the drive board and the bracket to increase the distance, effectively improving the convenience of operation.

[0018] Furthermore, the bracket includes an end plate, one end of the lead screw is rotatably mounted on the end plate, a rod body is fixedly provided on the side of the end plate near the drive plate, and the drive plate is slidably mounted on the rod body.

[0019] By setting the above structure, a sliding connection between the drive board and the bracket is achieved.

[0020] Furthermore, a protective ring is fixedly provided on the side of the drive plate away from the bracket, and both fixing components are installed inside the protective ring.

[0021] By setting up the above structure, when the finger supports the drive plate, it is possible to avoid contact between the finger and the fixed component and the lead screw.

[0022] Furthermore, the fixing component includes a fixing member and a mounting rod. The fixing member is used to fix the pipe cap. The lead screw has a through hole. One end of the mounting rod is fixedly connected to the fixing member, and the other end is slidably disposed in the through hole. A damping sleeve is fixedly sleeved on the mounting rod. The damping sleeve is used to increase the friction between the mounting rod and the inner wall of the through hole.

[0023] By setting the above structure, when one of the two fixing parts cannot rotate, the mounting rod and screw corresponding to the fixing part will rotate relative to each other. That is, when one of the two caps is tightened, the distance between the drive plate and the bracket can be changed to tighten the other cap until both caps are tightened on the corresponding pipe body.

[0024] Furthermore, the fixing component includes a sleeve, a cover, and a plurality of elastic plates distributed along the circumference of the cover. The sleeve is fixedly connected to the end of the lead screw, and the cover is fixedly connected to the mounting rod. The cover is slidably disposed within the sleeve. The plurality of elastic plates are all fixedly installed at the end of the cover away from the mounting rod. The free ends of the elastic plates are bent away from the axis of the cover. When the end of the cap is in contact with the cover and pushes the cover into the sleeve, the inner wall of the sleeve squeezes the elastic plates, so that the plurality of elastic plates are tightly embedded between the cap and the inner wall of the sleeve.

[0025] By setting up the above structure, the fastener can quickly fix and remove the pipe cap, and the fixing effect is stable.

[0026] Furthermore, the free end of the elastic sheet is provided with an elastic protrusion. When the elastic sheet is tightly embedded between the cap and the inner wall of the sleeve, the elastic protrusion is squeezed and deformed.

[0027] By setting up the above structure, the stability of the connection between the fastener and the cap is further improved.

[0028] Furthermore, a limiting head is fixedly provided at the end of the mounting rod away from the fixing component. The diameter of the limiting head is larger than the diameter of the through hole. The limiting head is used to prevent the fixing component from falling off the lead screw.

[0029] A collection method, applied to a nasal swab collection device, the method comprising:

[0030] Preparation of materials before collection;

[0031] Verify the information of the person being collected, inform the person being collected of the purpose and precautions, and obtain the cooperation of the person being collected;

[0032] Assist in adjusting the sampling position, attach the examination label to the collection tube and indicate left and right, the person being sampled removes the medical surgical mask, and check the person's nasal cavity for any abnormalities;

[0033] The caps of the two collection tubes are fixed to the two fixing components respectively, and the caps and nasal swabs are removed from the tube body by the driving component.

[0034] Allow the person being sampled to relax their head naturally. Insert two nasal swabs into both nasal cavities through the bracket to a depth of 1-1.5 cm. After holding for 10 seconds, control the fixing component and the nasal swabs to rotate clockwise through the drive component. While rotating and wiping, slowly remove the swabs.

[0035] The nasal swab is placed into the tube, and the fixed component is rotated by the drive component. The rotation of the fixed component causes the tube cap to be tightened on the tube. The collection tube is then placed into a sealed bag and put into a container.

[0036] Inform the person whose data was collected that the data collection process has ended.

[0037] The beneficial effects of this invention are:

[0038] 1. This invention, by setting up a driving component and a fixing component, enables the simultaneous operation of two nasal swabs to collect biological samples from both nasal cavities. During nasal sample collection, the driving component drives the caps to rotate the nasal swabs, effectively improving collection efficiency while ensuring collection quality. Furthermore, when the collection tube cannot rotate (i.e., when the tube body is squeezed by hand), the driving component simultaneously drives both caps to rotate, allowing both caps to be screwed onto the two collection tubes in one go, or unscrewed from the two collection tubes in one go.

[0039] 2. By setting up a drive plate, ball nut assembly and lead screw, the present invention can drive the fixed component to rotate by simply changing the distance between the drive plate and the bracket. Moreover, by controlling the increase or decrease of the distance, the rotation direction of the fixed component can be changed.

[0040] 3. By incorporating a compression spring, this invention allows for easy operation. During use, it is only necessary to control the distance between the drive plate and the bracket to decrease. When an increase is needed, the pressure is reduced, and the compression spring automatically resets the distance between the drive plate and the bracket, thus improving the convenience of operation.

[0041] 4. This invention achieves the transmission connection between the fixing component and the lead screw through the mounting rod and damping sleeve. When one of the two fixing components cannot rotate, the mounting rod corresponding to that fixing component rotates relative to the lead screw. For example, after one of the two pipe caps is tightened, the distance between the drive plate and the bracket can be changed to tighten the other pipe cap until both pipe caps are tightened onto the corresponding pipe body.

[0042] 5. By setting up a sleeve, a cover and an elastic plate, the present invention enables the fastener to quickly fix and disassemble the pipe cap, and the fixing effect is stable. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example 1:

[0055] like Figures 1-5 As shown, a nasal swab collection device according to this embodiment includes:

[0056] Bracket 1;

[0057] The collection tube 2 includes a tube body 21, a tube cap 22, and a nasal swab 23. The nasal swab 23 is fixedly connected to the tube cap 22, and the tube cap 22 is threadedly connected to the tube body 21.

[0058] Two identical fixing components 3 are rotatably mounted on the bracket 1 and are arranged in parallel between each other. The fixing components 3 are used to fix the pipe cap 22.

[0059] The drive component 4 is mounted on the bracket 1 and is connected to the two fixed components 3 in a transmission manner, and is used to drive the two fixed components 3 to rotate.

[0060] When the two nasal swabs 23 are inserted into the nasal cavities on both sides, the drive assembly 4 drives the two nasal swabs 23 to rotate through the two fixing components 3.

[0061] When collecting biological samples, two nasal swabs 23 can be operated simultaneously to collect biological samples from both nasal cavities. During nasal sample collection, the drive assembly 4 drives the caps 22 to rotate the nasal swabs 23, effectively improving collection efficiency while ensuring collection effectiveness. Furthermore, when the collection tube 2 cannot rotate (i.e., when the tube body 21 is squeezed), the drive assembly 4 simultaneously drives both caps 22 to rotate, allowing both caps 22 to be screwed onto and unscrewed from the two collection tubes 2 in one operation. This enables rapid and accurate biological sample collection, significantly improving efficiency, especially when collecting samples from large numbers of people. The collection device in this embodiment can also be rinsed and disinfected, allowing for repeated use.

[0062] In some other embodiments, a fixing base can also be provided to fix the collection tube 2 on the fixing base, so that when collecting biological samples, it is not necessary to manually squeeze the tube body 21 of the collection tube 2.

[0063] In this embodiment, the driving component 4 includes a driving plate 41, a ball nut assembly 42, and a lead screw 43. The driving plate 41 is slidably mounted on the bracket 1 along its length. Both ball nut assemblies 42 are fixedly connected to the driving plate 41. Both lead screws 43 are rotatably mounted on the bracket 1, and the ball nut assemblies 42 are threadedly connected to the lead screws 43. The two fixed components 3 are respectively connected to the two lead screws 43. In other embodiments, a small drive motor and gear set can be directly installed to drive the fixed components 3 to rotate. In this embodiment, by setting the driving plate 41, ball nut assembly 42, and lead screw 43, during use, only the distance between the driving plate 41 and the bracket 1 needs to be changed to drive the fixed components 3 to rotate through the ball nut assembly 42 and lead screw 43. Moreover, controlling the increase or decrease of the distance can change the rotation direction of the fixed components 3. The operation is simple and quick, and it can effectively reduce weight and cost, and facilitate subsequent rinsing and disinfection.

[0064] In this embodiment, one end of the lead screw 43 is rotatably connected to the bracket 1, and the other end is provided with a limit ring 431. The limit ring 431 cooperates with the bracket 1 to limit the movement range of the drive plate 41. A compression spring 411 is provided between the drive plate 41 and the bracket 1. One end of the compression spring 411 abuts against the bracket 1, and the other end abuts against the drive plate 41. When the distance between the drive plate 41 and the bracket 1 decreases, the compression spring 411 is used to automatically reset and increase the distance between the drive plate 41 and the bracket 1. In use, it is only necessary to control the distance between the drive plate 41 and the bracket 1 to decrease. When it is necessary to increase the distance, the pressure is reduced, and the compression spring 411 can automatically reset and increase the distance between the drive plate 41 and the bracket 1, effectively improving the convenience of operation.

[0065] In this embodiment, the bracket 1 includes an end plate 11. One end of the lead screw 43 is rotatably mounted on the end plate 11. A rod 12 is fixedly disposed on the side of the end plate 11 near the drive plate 41. The drive plate 41 is slidably mounted on the rod 12. By setting the rod 12, a sliding connection between the drive plate 41 and the bracket 1 is achieved. In this embodiment, a compression spring 411 is sleeved on the rod 12, which can constrain the deformation direction of the compression spring 411 and prevent it from twisting arbitrarily.

[0066] In this embodiment, a protective ring 412 is fixedly installed on the side of the drive plate 41 away from the bracket 1, and both fixing components 3 are installed inside the protective ring 412. When the fingers support the drive plate 41, contact between the fingers and the fixing components 3 and the lead screw 43 can be avoided. In this embodiment, during use, the index and middle fingers can be used to support the two ends of the drive plate 41 respectively, and the thumb can press the end plate 11 to adjust the distance between the drive plate 41 and the bracket 1. In fact, a suitable and comfortable support and pressing method can also be adopted according to personal habits, such as the thumb and middle finger supporting the two ends of the drive plate 41 respectively, and the index finger pressing the end plate 11.

[0067] In this embodiment, the fixing component 3 includes a fixing member 31 and a mounting rod 32. The fixing member 31 is used to fix the pipe cap 22. A through hole 432 is provided on the lead screw 43. One end of the mounting rod 32 is fixedly connected to the fixing member 31, and the other end is slidably disposed in the through hole 432. A damping sleeve 321 is fixedly sleeved on the mounting rod 32. The damping sleeve 321 is used to increase the friction between the mounting rod 32 and the inner wall of the through hole 432. In some other embodiments, the mounting rod 32 can also be directly connected to the lead screw 43 to prevent rotation. In this embodiment, the fixed component 3 and the lead screw 43 are connected by the mounting rod 32 and the damping sleeve 321. When one of the two fixed parts 31 cannot rotate, the mounting rod 32 corresponding to the fixed part 31 and the lead screw 43 rotate relative to each other. That is, when one of the two caps 22 is tightened, the distance between the drive plate 41 and the bracket 1 can be changed to tighten the other cap 22 until both caps 22 are tightened on the corresponding tube body 21, ensuring that both caps 22 can be tightened on the tube body 21.

[0068] It should be noted that in rare cases where the connection between the cap 22 and the pipe body 21 is particularly tight and the cap 22 cannot be loosened by using the fixing component 3, the cap 22 must be loosened manually first.

[0069] In this embodiment, the fixing member 31 includes a sleeve 311, a cover 312, and a plurality of elastic pieces 313 distributed along the circumference of the cover 312. The sleeve 311 is fixedly connected to the end of the lead screw 43, and the cover 312 is fixedly connected to the mounting rod 32. The cover 312 is slidably disposed within the sleeve 311. The plurality of elastic pieces 313 are all fixedly installed at the end of the cover 312 away from the mounting rod 32. The free end of the elastic piece 313 is bent away from the axis of the cover 312. The gap between the cap 22 and the inner wall of the sleeve 311 is slightly smaller than the thickness of the elastic piece 313. When the end of the cap 22 is in contact with the cover 312 and pushes the cover 312 into the sleeve 311, the inner wall of the sleeve 311 squeezes the elastic pieces 313, so that the plurality of elastic pieces 313 are tightly embedded between the cap 22 and the inner wall of the sleeve 311. In some other embodiments, the fastener 31 can also be configured as a clamp-type fastener 31. In this embodiment, by setting the sleeve 311, the cover 312 and the elastic piece 313, the fastener 31 can quickly fix and disassemble the pipe cap 22, and the fixing effect is stable.

[0070] In this embodiment, the free end of the elastic sheet 313 is provided with an elastic protrusion 314. When the elastic sheet 313 is tightly embedded between the inner wall of the cap 22 and the sleeve 311, the elastic protrusion 314 is squeezed and deformed, which further improves the stability of the connection between the fastener 31 and the cap 22.

[0071] In this embodiment, a limiting head 322 is fixedly provided at the end of the mounting rod 32 away from the fixing member 31. The diameter of the limiting head 322 is larger than the diameter of the through hole 432. The limiting head 322 is used to prevent the fixing component 3 from falling off the lead screw 43.

[0072] In some embodiments, an auxiliary support bracket can be used to fix the collection device, thereby reducing the workload of medical staff. For example, a conventional flexible bracket or a height-adjustable fixed bracket can be used. The collection device is fixed by clamps on the auxiliary support bracket. Specifically, the clamps can be used to hold the collection device at the protective ring 412.

[0073] Example 2:

[0074] A collection method, applied to the nasal swab collection device 23 of Embodiment 1, the method includes:

[0075] Preparation of materials before collection: such as two collection tubes, a piece of gauze, a container with a radioactive warning label, a radioactive warning label, two radioactive biological sample collection registration cards, a collection personnel information card, a disposable surgical mask, two pairs of latex gloves, a medium (small) trash can with a double-layered yellow bag inside, a medical waste can, label paper, a pen, etc.

[0076] The information of the personnel being sampled is verified, and the radioactive biological sample collection registration card is registered.

[0077] Inform the individuals being sampled of the purpose of the sample collection and the precautions to be taken, and obtain their cooperation.

[0078] Assist in adjusting the sampling position;

[0079] Attach the examination label to collection tube 2 and indicate left or right (i.e., indicate the left nasal cavity or the right nasal cavity).

[0080] The person being sampled removed their medical surgical mask;

[0081] Check the nasal cavity of the person being sampled for any abnormalities;

[0082] The caps 22 of the two collection tubes 2 are fixed on the two fixing components 3 respectively, and the caps 22 and nasal swabs 23 are removed from the tube body 21 by the driving component 4.

[0083] In this embodiment, specifically:

[0084] First, insert the caps 22 of the two collection tubes 2 into the sleeve 311, so that the ends of the caps 22 fit against the cover 312. Then, push the cover 312 into the sleeve 311. During this process, the inner wall of the sleeve 311 compresses the elastic pieces 313, so that multiple elastic pieces 313 are tightly embedded between the caps 22 and the inner wall of the sleeve 311, until the cover 312 fits against the inner end wall of the sleeve 311.

[0085] Then, pinch the two tubes 21 tightly with one hand, and support the two ends of the drive plate 41 with the index and middle fingers of the other hand, respectively, and press the end plate 11 with the thumb to reduce the distance between the drive plate 41 and the end wall of the bracket 1. During this process, the ball nut assembly 42 forces the lead screw 43 to rotate. The lead screw 43 drives the tube cap 22 to rotate counterclockwise through the damping sleeve 321, mounting rod 32, sleeve 311, cap 312 and elastic plate 313 until both tube caps 22 are unscrewed from the tubes 21, and then the nasal swab 23 is removed from the tubes 21.

[0086] Allow the person being sampled to relax their head naturally. Insert two nasal swabs 23 into the nasal cavities on both sides through the bracket 1 to a depth of 1-1.5cm. After 10 seconds, control the fixing component 3 and the nasal swabs 23 to rotate clockwise multiple times through the drive component 4. While rotating and wiping, slowly remove them.

[0087] In this embodiment, specifically:

[0088] First, allow the person being sampled to relax their head naturally, and insert two nasal swabs 23 into both nasal cavities through the bracket 1 to a depth of 1 to 1.5 cm;

[0089] After pausing for 10 seconds, the nasal swab 23 is slowly withdrawn from both nasal cavities. Simultaneously, the pressure of the thumb on the end plate 11 is gradually released, allowing the compression spring 411 to return to its original deformation, thus increasing the distance between the drive plate 41 and the end wall of the bracket 1. During this process, the ball nut assembly 42 forces the lead screw 43 to rotate. The lead screw 43, through the damping sleeve 321, mounting rod 32, sleeve 311, cover 312, and elastic plate 313, drives the cap 22 to rotate clockwise. In this embodiment, visually, three clockwise rotations of the nasal swab 23 are sufficient to stop releasing the pressure of the thumb on the end plate 11.

[0090] In some other embodiments, while rotating and wiping, the nasal swab 23 can be slowly removed, or the collection device can be used to rotate the nasal swab 23 while moving it along the inner wall of the nasal cavity. That is, the nasal swab 23 rotates itself while circulating along the inner wall of the nasal cavity, further improving the collection effect.

[0091] Place the nasal swab 23 into the tube body 21, and control the rotation of the fixing component 3 through the drive component 4. The rotation of the fixing component 3 causes the tube cap 22 to be tightened on the tube body 21. Put the collection tube 2 into the sealed bag and place it into the container.

[0092] In this embodiment, specifically:

[0093] Insert the nasal swab 23 into the tube body 21 so that the cap 22 abuts against the tube body 21;

[0094] Then, the thumb disengages from the end plate 11, causing the compression spring 411 to continue to recover its deformation, forcing the distance between the drive plate 41 and the end wall of the bracket 1 to continue to increase. During this process, the ball nut assembly 42 forces the lead screw 43 to rotate. The lead screw 43 drives the tube cap 22 to continue to rotate clockwise through the damping sleeve 321, mounting rod 32, sleeve 311, cover 312 and elastic plate 313 until the tube cap 22 is tightened on the tube body 21. Then, the collection tube 2 is put into the sealed bag and placed in the container.

[0095] Inform the person whose data was collected that the data collection process has ended.
