AI Technical Summary
Existing portable HPV testing sticks have an unstable connection between the testing head and the container during sample storage, which can easily cause the sample to come into contact with the inner wall and port of the container, posing a risk of sample loss and contamination.
The device employs a design consisting of a shrinkable outer shell, a telescopic rod, a detection head, a strip-shaped fixing block, a limiting through-slide groove, and a pushing slider. By pushing the slider, the telescopic rod is positioned and slids within the strip-shaped fixing groove. After the detection head is inserted into the cervix to take a sample, it retracts into the shrinkable outer shell. The protective cylindrical cover and sealing ring are used for sealing to ensure that the detection head is stably positioned within the outer shell.
This technology enables the detection head to retract precisely into the storage shell after sampling, avoiding contact with the inner wall, thus improving the safety of sample preservation and transportation, and reducing the risk of sample loss and contamination.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of HPV testing stick technology, specifically relating to a portable HPV testing stick. Background Technology
[0002] Regular HPV testing can detect HPV infection in the body in a timely manner, allowing for early treatment and preventing the condition from worsening. HPV testing generally requires a doctor to collect cervical fluid samples from the patient. Due to the current rampant epidemic, frequent visits to the hospital for testing have a certain impact on public health and safety, while delaying testing is not conducive to timely treatment for patients.
[0003] To address this, a portable HPV testing stick, with announcement number "CN216417232U", includes a stick body, a brush head at one end of the stick body, a base plate at the bottom of the brush head, the stick body passing through the base plate, and a canister covering the brush head, which is connected to the base plate by threads. The design is ingenious and reasonable. During use, the base plate is held in place, the stick is inserted into the body, and the brush head is used to scrape the cervix to obtain a sample. After removing the brush head, the canister is closed, and the sample is stored inside for convenient transportation and carrying.
[0004] However, for the aforementioned portable HPV testing stick, although the brush head is covered by a canister connected to the base plate via threads, and the stick has a scale strip, the following obvious defects still exist during use: Since the brush head is used for sample preservation and transportation via the connection between the base plate and the canister, the sample preservation canister and the brush are separate. Therefore, after inserting the brush into the canister, because the stick does not have a corresponding structural shell to protect the sample in time, the sample may come into contact with the inner wall of the canister and the edge of the port during combined preservation. Utility Model Content
[0005] The purpose of this invention is to provide a portable HPV testing stick to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable HPV testing stick, comprising:
[0007] The retractable shell contains a telescopic rod for sampling, which retracts and positions itself within the shell. One end of the telescopic rod has a detection head that reciprocates. Inside the retractable shell are strip-shaped blocks that allow the telescopic rod to slide and retract in a directional manner. One end of the retractable shell has a protective cylindrical cover that provides a threaded seal to the detection head after sampling, allowing it to retract into the shell. The protective cylindrical cover has a threaded locking end and an outwardly extending threaded positioning groove at one end inside the retractable shell. One end of the detection head has a protective plate with positioning blocks on both outer sides.
[0008] Preferably, the outer surface of the shrinkable shell is provided with a long strip-shaped limiting through groove, and a push slider is slidably limited within the limiting through groove, which can drive the telescopic rod to perform positioning, telescopic movement, and timely protection of the sample inside the shrinkable shell.
[0009] Preferably, one side of the strip-shaped block is provided with a strip-shaped groove, and the telescopic rod is positioned and slidably in the strip-shaped groove. One end of the telescopic rod is fixed to the end of the push slider located inside the shrinking shell, ensuring the stability of the telescopic rod during the extension and retraction process.
[0010] Preferably, the protective cylindrical cover is locked in the threaded positioning groove at one end of the shrink shell to press and position the detection head, which can keep the detection head stable inside the shrink shell and prevent it from contacting the inner wall.
[0011] Preferably, the positioning blocks on both sides of the protective plate slide within the threaded positioning lock groove and are pressed by the protective cylindrical cover to position the detection head inside the protective cylindrical cover, thereby ensuring that the sample on the detection head is in a sealed positioning space.
[0012] Preferably, a sealing ring is fitted onto one end of the threaded surface of the protective cylindrical cover, and the sealing ring seals the sample after the protective cylindrical cover is locked onto one end of the shrink shell, making the sample more convenient and safer to transport.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This portable HPV test strip, through the coordinated use of a shrinkable shell, a telescopic rod, a test head, a strip-shaped fixing block, a limiting through groove, and a pushing slider, uses the pushing block to position and slide the telescopic rod in the strip-shaped fixing groove, allowing the protective plate and the test head to extend to the outside of one end of the shrinkable shell, thus allowing it to be inserted into the cervix to obtain a sample. After obtaining the sample, the telescopic rod retracts quickly and stably into the shrinkable shell, maintaining a stable position. This ensures that the test head remains stable within the shrinkable shell, preventing the test head from touching the inner wall or port during storage. Furthermore, it accurately retracts the test head into the storage shell after sampling, further improving the safety of the test sample.
[0014] By using the internal threaded locking groove at one end of the shrinking outer shell and the positioning block within the threaded locking groove of the protective plate, the threaded end of the protective cylindrical cover is locked in the threaded locking groove. At the same time, the sealing rubber ring seals the locking point. After the detection head retracts into the shrinking outer shell, it is locked inside by the protective cylindrical cover. The positioning block is also pressed into the positioning groove, which further reinforces and seals the detection head inside the protective cylindrical cover, reducing the phenomenon of the detection head shaking and touching the inner wall. This also facilitates the preservation and transportation of samples. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a portable HPV testing stick, comprising:
[0021] The constricting outer shell 1 contains a retractable rod 2 for sampling, which retracts and positions itself within the shell. This facilitates the insertion of a detection head 3 into the cervix for sampling. One end of the retractable rod 2 is equipped with the detection head 3, which reciprocates to scrape and collect the sample to be tested from the cervix. The constricting outer shell 1 also includes a strip-shaped fixing block 4 inside to guide the retracting and extending of the retractable rod 2, ensuring the stability of the detection head 3. One end of the protective cylindrical cover 5 is provided to retract the sampling detection head 3 into the shrink shell 1 for threaded sealing. The protective cylindrical cover 5 can position and press the detection head 3 inside it to maintain its position stability. The threaded locking end of the protective cylindrical cover 5 and the end inside the shrink shell 1 are provided with an outwardly extending threaded positioning locking groove 6, which can lock and fix the protective cylindrical cover 5 to one end of the shrink shell 1. One end of the detection head 3 is provided with a protective plate 7, and the outer two sides of the protective plate 7 are positioned by positioning blocks 8 to keep the detection head 3 stable inside the shrink shell 1.
[0022] The outer surface of the retractable outer shell 1 is provided with a long, narrow, through-slide groove 9, which allows the push slider 10 to slide inside the surface of the through-slide groove 9. The push slider 10 slides within the through-slide groove 9, pushing the telescopic rod 2 to perform positioning, telescopic, and telescopic sliding. One side of the strip-shaped fixing block 4 is provided with a strip-shaped fixing groove 11, which keeps the telescopic rod 2 stable during telescopic extension and contraction and prevents it from shaking and touching the inner wall. The telescopic rod 2 slides in the strip-shaped fixing groove 11, and one end of the telescopic rod 2 is fixed to the end of the push slider 10 located inside the retractable outer shell 1. The protective cylindrical cover 5 is locked in the threaded positioning locking groove 6 at one end of the retractable outer shell 1 to press and position the detection head 3.
[0023] The positioning blocks 8 on both sides of the protective plate 7 are positioned and slid in the threaded positioning lock groove 6 and are pressed by the protective cylindrical cover 5 to position the detection head 3 inside the protective cylindrical cover 5. A sealing ring 12 is sleeved on the outside of one end of the threaded surface of the protective cylindrical cover 5, and the sealing ring 12 is sealed after the protective cylindrical cover 5 is locked to one end of the shrink shell 1, which can effectively protect the sample on the detection head 3 during transportation.
[0024] Specifically, in use, firstly, the protective cylindrical cover 5 is removed from the threaded positioning groove 6 at one end of the contraction shell 1. Then, the pushing slider 10 is pushed to slide to one side within the limiting through groove 9, so that the sliding of the pushing slider 10 pushes the telescopic rod 2 to be positioned and slid in the strip-shaped groove 11 on one side of the strip-shaped fixing block 4. This ensures that the telescopic rod 2 maintains a stable position during extension and retraction. At this time, the directional movement of the telescopic rod 2 causes the protective plate 7 and the detection head 3 to extend outside the contraction shell 1 to a certain length, and then the detection head 3 is inserted into the cervix through the telescopic rod 2 to scrape and collect a sample. After the sample is obtained, the pushing slider 10 is pushed to the limiting through groove 9. The telescopic rod 2 moves back through the sliding groove 9, allowing it to be oriented in the strip groove 11 and precisely center the detection head 3 carrying the sample, quickly retracting it into the shrink shell 1. This prevents the detection head 3 from touching the inner wall and port, ensuring the safety of the sample inside the shrink shell 1. After the detection head 3 retracts into the shrink shell 1, it is locked inside by the protective cylindrical cover 5, and the positioning block 8 is pressed and positioned, further reinforcing and sealing the detection head 3 inside the protective cylindrical cover 5. This reduces the possibility of the detection head 3 shaking and touching the inner wall, and facilitates the preservation and transportation of the sample.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
