Description

Technical Field

[0001] This utility model relates to the field of medical consumables technology, specifically to a patient's nasal and throat collection brush that is easy to store in test tubes. Background Technology

[0002] Medical consumables refer to consumable materials and tools used in medical procedures. They mainly include disposable consumables, high-value consumables, in vitro diagnostic consumables, and special function consumables. Disposable consumables mainly consist of sampling consumables and basic operation consumables. Nasal and throat collection brushes are one of the common consumables in the sampling category. Nasal and throat collection brushes, also known as nasopharyngeal swabs or oropharyngeal swabs, are made of nylon fiber or polyester and are used to collect secretions from the back of the nasal cavity, throat, and nasopharynx to detect pathogens such as influenza and coronavirus. They meet sterile and non-toxic standards.

[0003] Existing collection brushes generally consist of a collection brush head and a collection rod. A break point is set at the middle of the connection between the collection brush head and the collection rod. The user needs to hold the collection rod and insert the collection brush head into the patient's nose and throat to collect pathogens. After collection, the collection head needs to be placed into a test tube and broken at the break point where the collection brush head and collection rod connect to complete the collection.

[0004] When the aforementioned collection brush is used to collect samples from the patient's nose and throat, the connection point between the brush head and the collection rod has a breakage point, resulting in limited connection strength. In actual use, if the collection rod or end is subjected to excessive force during collection, it may break, causing the collection brush to fall directly into the patient's throat, resulting in a medical accident and posing a safety hazard. Therefore, we propose a patient nasal and throat collection brush that is easy to store in test tubes. Utility Model Content

[0026] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides, for example Figures 1-4 The illustrated nasal and throat collection brush for easy test tube storage includes a main rod 1, one end of which is telescopically fitted with a linkage rod 2, and the other end of which is inserted with a disposable collection head 3. The main rod 1 includes an outer frame 101, and friction rings 102 are distributed on both sides of the outer wall of the outer frame 101. A protective sleeve 103 is fitted on one end of the outer frame 101.

[0029] To ensure the overall stability and usability of the collection brush when collecting samples from patients, such as Figure 1 As shown, this collection brush structure has friction rings 102 arranged at both ends of the outer rod frame 101, which can be easily held by the user to maintain stable friction. The protective sleeve 103 at the end is made of silicone, which can provide protection to avoid infection during the collection process. The protective sleeve 103 can be directly removed and discarded for the subsequent use of the main rod 1.

[0030] like Figures 2-3 As shown, the linkage rod 2 includes an inner rod 201. One end of the inner rod 201 is connected to a push cap 202. The outer wall of the other end of the inner rod 201 is fixed with a ring frame 203. A spring sleeve 204 is attached to one side of the ring frame 203. The inner rod 201 extends along the inner cavity 205 of the rod. A locking ring frame 206 is fixed to the inner wall of one end of the inner cavity 205. Clamping pieces 207 are attached to the four sides of the inner wall of the locking ring frame 206. A rubber layer 208 is attached to the inner wall of the clamping pieces 207. A limit sleeve 209 is fixed to the inner wall of one end of the inner cavity 205 of the rod.

[0031] To facilitate the storage of test tubes after collection and to maintain stability during the collection process, such as Figures 2-3 As shown, the outer rod frame 101 of this collection brush can clamp the insertion end 302 of the collection rod 301 around the inside through the clamping piece 207 at one end of the inner rod 201. With the elastic extension and contraction of the inner rod 201, the clamping piece 207 at one end of the inner rod 201 can be locked or released by the locking ring frame 206. This can keep the connection of the collection rod 301 stable during collection, and when storing, the collection rod 301 can be discharged by simply pressing the cap 202. The test tube storage process is convenient and the collection process is stable.

[0032] like Figure 4 As shown, the disposable collection head 3 includes a collection rod 301, and a collection brush 303 is fixed at one end of the collection rod 301, and a plug-in end 302 is fixed at the other end of the collection rod 301. A limiting sleeve 209 is sleeved on the outer wall of one end of the collection rod 301.

[0033] To reduce data collection and usage losses, such asFigure 4 As shown, the collection brush can be connected to the main rod 1 via the collection rod 301 connected to one end of the collection brush 303. When storage is required, the collection brush 303 can be simply placed into the test tube to complete the storage. Only the collection brush 303 and the collection rod 301 are disposable consumables, reducing usage losses.

[0034] In summary, when using this sampling brush structure, the user first presses the cap 202 and the inner rod 201 along the spring sleeve 204, causing the clamping plate 207 to unfold after being released from the limiting ring frame 206. At this time, the insertion end 302 of the sampling rod 301 to be used can be inserted into the limiting sleeve 209 and extended until it aligns with one end of the clamping plate 207 of the inner rod 201. Then, the user releases the pressure on the cap 202, at which point the inner rod 201 unfolds with the spring... When the elastic sleeve 204 returns to its original position, the clamping pieces 207 around the other end of the inner rod 201 retract with the locking ring frame 206 and clamp and fix the collection rod 301 around its perimeter. At this time, the user can carry out the collection process. After completion, the collection brush 303 is placed into the test tube. At this time, pressing the cap 202 will press the inner rod 201 simultaneously, and the clamping pieces 207 at the bottom of the inner rod 201 will release their clamping on the collection rod 301. The collection brush 303 will automatically be inserted into the test tube, completing the collection and storage process.
