Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and in particular to a sampler for medical testing. Background Technology

[0002] Swab sampling refers to the process of collecting samples from specific sites on the human body using strictly sterile medical devices (such as disposable sterile sampling swabs). These samples may contain microorganisms such as bacteria, viruses, and fungi, and are important evidence for clinical diagnosis. Sampling can be done by directly holding the swab by hand or using a separate device that clamps the swab for sampling. However, there is a risk of accidental breakage of the swab stem. Furthermore, direct manual collection can easily lead to accidental infection.

[0003] Existing technologies, such as a novel sampling device for medical testing (authorization number CN207946250U), can effectively prevent cotton swabs from being contaminated and affecting the experimental structure, and are generally suitable for testing sampling with higher precision.

[0004] Existing sampling swabs such as Figure 7 As shown, it is inconvenient to sample from inside the body that is far from the body surface, and it is also inconvenient to break the sample after sampling.

[0005] Currently, there is a lack of a sampler that facilitates sampling after swab installation and allows the swab to be broken after sampling.

[0006] Therefore, in order to address the above problems, a medical testing sampler is proposed to solve them. Utility Model Content

[0007] This invention addresses the shortcomings of existing technologies by developing a sampler for medical testing. This invention facilitates sampling after swab installation and allows the swab to be broken after sampling.

[0008] The technical solution to the problem solved by this utility model is as follows: This utility model provides a sampler for medical testing, including: a swab, the swab stem of which is provided with a breakage groove; a sleeve assembly, including a sleeve, the sleeve being connected to a protective tube, the end of the protective tube being connected to a breakage tooth; a handle assembly, including a handle, the handle being provided with a hollow groove, the handle being connected to symmetrical guide rods, a pin being disposed in the hollow groove, the pin passing through the handle, the pin being connected to symmetrical sliding plates, and the symmetrical guide rods passing through corresponding sliding plates; the sleeve is threadedly connected to the handle, the protective tube is matched with the swab, the breakage tooth is matched with the breakage groove, and the pin is matched with the protective tube. By using the sleeve assembly and handle assembly, the distance between medical staff and patients is extended, avoiding accidental infection. During sampling, the rear part of the swab is inside the protective tube, which can prevent the swab from breaking. After sampling, when it is necessary to break the swab, the pin pushes out the swab, so that the breakage groove and the breakage tooth are matched, facilitating breakage. Finally, the ejector pin pushes out the remaining swab rod, facilitating the recycling of the sleeve assembly.

[0009] As an optimization, the sleeve assembly is made of transparent plastic, making it easy to observe the position of the swab and the ejector pin.

[0010] As an optimization, a circular plate is connected inside the handle, the circular plate is connected to a motor, the output shaft of the motor is connected to a screw, the screw passes through the circular plate, and the screw is threadedly connected to the ejector pin. By using a motor to drive the movement and a screw, the movement of the ejector pin can be easily achieved.

[0011] As an optimization, the handle is connected to a switch, which is electrically connected to the motor. Using a switch facilitates control of the motor's rotation.

[0012] As an optimization, the swab protrudes outward to form a positioning ring, and the protective tube is provided with a break-out positioning groove and an installation positioning groove. The positioning ring matches the break-out positioning groove and the installation positioning groove. By using the installation positioning groove, the assembly of the swab and the sleeve assembly is facilitated, and by using the break-out positioning groove, positioning during breakage is facilitated.

[0013] As an optimization, the sleeve is connected with symmetrical rotating protrusions to facilitate the rotation of the sleeve.

[0014] As an optimization, the handle is connected to symmetrical limiting rings, making it convenient for medical staff to place their hands.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0016] (1) This device extends the distance between medical staff and patients by using sleeve components and handle components, thus avoiding accidental infection.

[0017] (2) By using a protective tube, the device ensures that the breakage groove is inside the protective tube during sampling, thus preventing the swab from breaking accidentally.

[0018] (3) This device uses a motor to drive the ejector pin to eject the swab, so that the break groove is in the position of the break teeth, making it easy to break. Then, the remaining swab rod fragments are ejected, making it easy to recycle the sleeve assembly. Attached Figure Description

[0032] like Figures 1 to 6As shown in Embodiment 1: A medical testing sampler includes: a swab 1, the swab 1 having a breakage groove 11 on its swab stem; a sleeve assembly 2, including a sleeve 23 connected to a protective tube 22, the end of the protective tube 23 being connected to a breakage tooth 21; and a handle assembly 3, including a handle 32 having a hollow groove 36 connected to symmetrical guide rods 35. A pin 31 is disposed within the hollow groove 36, passing through the handle 32. The pin 31 is connected to symmetrical sliding plates 37, and the symmetrical guide rods 35 pass through their respective sliding plates 37. The sleeve 23 is threadedly connected to the handle 32. The protective tube 22 matches the swab 1, the breakage tooth 21 matches the breakage groove 11, and the pin 31 matches the protective tube 22. By using the sleeve assembly 2 and the handle assembly 3, the distance between medical personnel and patients is increased, avoiding accidental infection. During sampling, the rear of swab 1 is inside the protective tube 22, which prevents swab 1 from breaking. After sampling, if swab 1 needs to be broken, the ejector pin 31 pushes out swab 1, aligning the breakage groove 11 with the breakage tooth 21 for easy breaking. Finally, the ejector pin 31 pushes out the remaining swab rod, facilitating the recovery of the sleeve assembly 2.

[0033] The sleeve assembly 2 is made of transparent plastic, which makes it easy to observe the position of the swab 1 and the pin 31.

[0034] The handle 32 is internally connected to a circular plate 38, which is connected to a motor 39. The output shaft of the motor 39 is connected to a screw 310, which passes through the circular plate 38 and is threadedly connected to the ejector pin 31. By using a motor 39 and a screw 310, the movement of the ejector pin 31 is easily achieved.

[0035] The motor 39 is model ZGX38REE.

[0036] The handle 32 is connected to the switch 34, which is electrically connected to the motor 39. The use of the switch 34 facilitates control of the rotation of the motor 39.

[0037] The sleeve 23 is connected to symmetrical rotating protrusions 26, which facilitates the rotation of the sleeve 23.

[0038] The handle 32 is connected to a symmetrical limiting ring 33, which facilitates the placement of medical staff's hands.

[0039] The workflow of this embodiment is as follows:

[0040] The swab 1 and the sleeve assembly 2 are assembled in the factory. The break groove 11 is located inside the protective tube 22, away from the break teeth 21, and is vacuum packaged.

[0041] To use, unpack the package, tighten the sleeve 23 onto the handle 32 until it contacts a limiting ring 33. Hold the handle 32 to complete the sampling.

[0042] After sampling, turn on switch 34 to control motor 39 to rotate. Motor 39 drives screw 310 to rotate, screw 310 drives ejector pin 31 to move, ejector pin 31 drives slide plate 37 to move along guide rod 35. Ejector pin 31 enters protective tube 22, contacts swab 1, and ejects swab 1, making the breakage groove 11 match the breakage tooth 21. Turn off switch 34. Press swab 1 with your thumb to quickly break swab 1. Turn on switch 34 to control motor 39 to continue rotating, so that ejector pin 31 ejects the remaining swab rod remnant of swab 1.

[0043] Example 2: This example further elaborates on Example 1. The swab 1 protrudes outward to form a positioning ring 12. The protective tube 22 is provided with a break-off positioning groove 24 and an installation positioning groove 25. The positioning ring 12 matches the break-off positioning groove 24 and the installation positioning groove 25. By using the installation positioning groove 25, the assembly of the swab 1 and the sleeve assembly 2 is facilitated. By using the break-off positioning groove 24, positioning during breakage is facilitated.

[0044] The workflow of this embodiment is as follows:

[0045] In the initial state, the positioning ring 12 is in the mounting positioning groove 25. When it breaks, the control motor 39 rotates so that the positioning ring 12 is in the broken positioning groove 24.

[0046] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
