Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a high-efficiency virus inactivation sampling head. Background Technology

[0002] Virus inactivation sampling heads generally refer to sampling tools such as throat swabs. They are usually used in conjunction with virus inactivation sampling tubes and are mainly used for virus collection and inactivation. After sampling, the virus inactivation sampling head is placed inside the sampling tube. The liquid inside the sampling tube will inactivate the virus, thereby preventing the virus from spreading or infecting the operator during the sampling process.

[0003] Existing virus inactivation sampling heads typically have a solid internal structure and an external arc-shaped, grooveless sampling tip at the front end of the throat swab. This structure limits the amount of viscous liquid that can be collected, making it inconvenient to increase the amount of liquid collected. Therefore, we propose a virus inactivation sampling head for efficient collection. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency virus inactivation sampling head includes: a pharyngeal swab, a sampling component, and a bending component; the pharyngeal swab includes a fixed rod at one end and a sampling fluff head installed at the front end of the fixed rod; the sampling component includes fixed blocks arranged and fixedly installed on both sides of the front end of the fixed rod, an elastic arc plate fixedly installed between the fixed blocks, and multiple collection cavities opened at the outer end of the sampling fluff head outside the elastic arc plate; the bending component includes a bending part provided on the fixed rod on one side of the sampling fluff head, an installation cavity opened inside the fixed rod, a support rod movably installed in the installation cavity at the inner end of the bending part, and a spring fixedly installed between one end of the support rod and one end of the fixed rod inside the installation cavity.

[0007] Preferably, all the collecting cavities are strip-shaped structures.

[0008] Preferably, a locking hole is also provided through one side of the support rod.

[0009] Preferably, a socket is also provided on one side of the fixing rod.

[0010] Preferably, a plug is also movably installed in the card hole and the insertion hole.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] 1. In this utility model, the sampling tip of the pharyngeal swab can be pressed appropriately during sampling, thereby pressing the elastic arc plate between the fixing blocks inside the sampling tip to bend. During the bending of the elastic arc plate, the sampling tip at its outer end will also be pressed inward. After the sampling tip is inward, the multiple collection cavities in its inward part will stick to a large amount of sampling liquid, thereby increasing the sampling volume and ensuring efficient collection during sampling.

[0013] 2. In this utility model, after sampling is completed, the insert at the outer end of the fixing rod can be removed, thereby moving the support rod at the inner end of the bend to the outer side of the fixing rod, so as to ensure that the bend is easy to break after sampling, thus facilitating the collection of the pharyngeal swab sampling head after sampling. In addition, the setting of the support rod at the inner end of the bend can also improve the strength of the bend when pressing during sampling of the sampling head, thereby avoiding the problem of accidental breakage.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a highly efficient virus inactivation sampling head.

[0024] Example 1:

[0025] Combination Figure 1-3 As shown, the present invention provides a high-efficiency virus inactivation sampling head, comprising: a pharyngeal swab 100, a sampling component 200, and a bending component 300; the pharyngeal swab 100 includes a fixing rod 101 at one end and a sampling filament 102 installed at the front end of the fixing rod 101; the sampling component 200 includes fixing blocks 201 arranged and fixedly installed on both sides of the front end of the fixing rod 101, an elastic arc plate 202 fixedly installed between the fixing blocks 201, and multiple sets of collection cavities 203 opened at the outer end of the sampling filament 102 outside the elastic arc plate 202, all of which are strip-shaped structures.

[0026] Specifically, a virus inactivation sampling head generally refers to sampling tools such as throat swabs, which are usually used in conjunction with virus inactivation sampling tubes, mainly for virus collection and inactivation. During sampling, the sampling fluff head 102 at the front end of this throat swab 100 can be pressed appropriately, thereby pressing the elastic arc plate 202 between the fixing blocks 201 inside the sampling fluff head 102 to bend. During the bending of the elastic arc plate 202, the sampling fluff head 102 at its outer end will also be pressed inward. After the sampling fluff head 102 is inward, the multiple sets of collection cavities 203 in its inward part will stick to a large amount of sampling liquid, thereby increasing the sampling volume and ensuring efficient collection during sampling.

[0027] Example 2:

[0028] Combination Figure 2-4 As shown, based on Embodiment 1, the bending assembly 300 includes a bending portion 301 provided on a fixing rod 101 on one side of the sampling felt head 102, an installation cavity 302 opened in the fixing rod 101, a support rod 303 movably installed in the installation cavity 302 inside the bending portion 301, and a spring 304 fixedly installed between one end of the support rod 303 and one end of the fixing rod 101 in the installation cavity 302. A locking hole 305 is also opened through one side of the support rod 303, and an insertion hole 306 is also opened on one side of the fixing rod 101. Insertion posts 307 are movably installed in the locking hole 305 and the insertion hole 306.

[0029] Specifically, after sampling, the insert 307 at the outer end of the fixing rod 101 can be removed, thereby moving the support rod 303 at the inner end of the bent portion 301 to the outer side of the fixing rod 101 by the elastic force of the spring 304. This ensures that the bent portion 301 is easy to break after sampling, which facilitates the collection of samples from the sampling head 102 at the front end of the pharyngeal swab 100. The setting of the support rod 303 at the inner end of the bent portion 301 can also improve the strength of the bent portion 301 when the sampling head 102 is pressed during sampling, thereby avoiding accidental breakage during sampling.

[0030] Working principle and usage process of this utility model:

[0031] When medical staff use a throat swab 100 to collect samples, they first insert the sampling tip 102 into the patient's mouth and rotate the fixing rod 101 appropriately so that the collection cavity 203 at the outer end of the sampling tip 102 is positioned above or below the sampling site. Then, they press the sampling tip 102 appropriately to collect the sample. After pressing, the elastic arc plate 202 at its inner end bends and deforms, causing the collection cavity 203 at the outer end of the sampling tip 102 to concave inward. The concave collection cavity 203 collects samples from the sampling site. After sampling, remove the pharyngeal swab 100 and remove the insertion post 307 at the outer end of the fixing rod 101. After the insertion post 307 is removed, the spring 304 at the rear end of the support rod 303 inside the fixing rod 101 will pull the support rod 303 to move, thereby moving the support rod 303 out of the inner end of the bending part 301. At this time, when the sampling fluff 102 is placed in the sampling tube and bent, the sampling fluff 102 can be easily broken off at the bending part 301, so as to conveniently collect the sampled sampling fluff 102 into the sampling tube.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
