Description

Technical Field

[0001] The present invention relates to the technical field of oral medical instruments, and in particular to an oral mucosa scraping device. Background Art

[0002] Oral mucosal cells can be used for genetic testing; the main principle is to take oral mucosal cells, amplify their genetic information, and then use specific equipment to detect the DNA molecular information in the cells to predict the risk of disease in the body. A method of using specific equipment to detect the DNA molecular information in the cells of the person being tested, analyze the gene types and gene defects it contains, and whether its expression function is normal, so that people can understand their own genetic information, identify the cause of the disease or predict the risk of a certain disease in the body. Oral mucosal cells are usually collected by scraping.

[0003] In the prior art, there is a closed-mouth tongue-scraping saliva DNA sampler provided by the authorization announcement number CN114403944B. The user first unscrews the collection tube and the preservation solution bottle cap, and separates the color-developing sealing strip and the hand-held stick by pulling the hand-held stick, and takes out the oral absorption ball; the user puts the oral absorption ball into the mouth, and drives the oral absorption ball to rotate by the hand-held stick; through the cooperation of the eccentric impact ball shell, the tongue-scraping slide bar and the fixed force block, the user's tongue is stimulated and the cells on the tongue are scraped, and the saliva with the exfoliated cells is adsorbed into the liquid storage cavity of the oral absorption ball; after rotating for a period of time, the oral absorption ball is taken out of the mouth and placed in the collection tube, and the mouth is pressed by the hand-held stick. The oral suction ball squeezes out the saliva sample stored in it into the oral suction ball, and the oral suction ball is taken out and placed at a recovery point; the tongue scraper slide bar and the tongue scraper weight bead are guided by a guide tube, and when the oral suction ball is pressed to squeeze out the saliva sample, the tongue scraper weight bead and the tongue scraper slide bar are synchronized, so that the saliva can fully contact the tongue scraper slide bar, increase the content of exfoliated cells in the saliva sample, and improve the sampling success rate; during the rotation of the oral suction ball, the auxiliary sliding bead can continuously slide on the flower-shaped sliding ring, and then continuously act on the breathing elastic pad, so that the breathing elastic pad produces an undulating motion, which promotes the absorption of saliva by the oral suction ball and the wrapped liquid storage bag, and improves the efficiency of saliva sampling.

[0004] It has a major disadvantage: when in use, the oral absorbent ball needs to be rotated to enable the auxiliary sliding beads to act on the breathing elastic pad, causing the breathing elastic pad to produce an ups and downs motion, thereby promoting the oral absorbent ball and the wrapped liquid storage bag to absorb saliva, and a long rotation time is required to complete the absorption of saliva in the oral cavity. Summary of the invention

[0005] The embodiment of the present application provides an oral mucosal scraping device, which solves the problem in the prior art that when in use, the auxiliary sliding beads need to be rotated by the oral absorbent ball to act on the breathing elastic pad, causing the breathing elastic pad to produce an undulating motion, thereby promoting the absorption of saliva by the oral absorbent ball and the wrapped liquid storage capsule, and requiring a long rotation time to complete the absorption of saliva in the oral cavity, thereby optimizing the internal structure of the scraping device, simplifying the production technology and process, and improving the production efficiency and cost. At the same time, by softening the absorbent ball as a whole, the protrusion effect of the scraper rod is more obvious when the rotating rod is rotated, which can improve the shedding of cells in the user's oral cavity. When the absorbent ball is deformed by the force of the rotating rod, the volume of the internal cavity becomes smaller, and during the resetting process, negative pressure can be generated to improve the effect of absorbing saliva; the oblate spheroid-shaped absorbent ball can be more convenient for the user to put into the mouth.

During the forward and backward movement, the saliva gathered in both sides of the user's oral cavity can be collected, and both sides of the oral cavity can be stimulated at the same time, thereby improving the efficiency of saliva production and collection. At the same time, when the two scraping components are placed in a V-shape on both sides of the user's oral cavity, the two rotating rods can be pressed so that the liquid absorption balls can press both sides of the user's tongue, thereby improving the production and collection of saliva, expanding the stimulation area, and at the same time, the insertion width can be adjusted according to the size of the user's oral cavity to adapt to the size of the oral cavity of different users;

[0036] Fourthly, by adding scraping rope and absorption rope, the contact area with the user's tongue can be increased during use, thereby increasing the stimulation area of ​​the tongue.

[0049] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0050] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0052] Embodiment 1: Figure 1-Figure 4 As shown, the present application provides an oral mucosa scraping device, comprising a scraping component 100 and a storage component 200;

[0053] The scraping assembly 100 includes a rotating rod 110, and the rotating rod 110 is cylindrical;

[0054] The storage assembly 200 includes a storage tube 210 and a fixed cover 220;

[0055] The fixed cover 220 is threadedly connected to the storage tube 210, the scraping assembly 100 is located in the storage assembly 200, and one end of the rotating rod 110 is arranged on the top side of the fixed cover 220;

[0056] The scraping assembly 100 further includes a liquid absorbing ball 120, a supporting ball 130 and a scraping rod 140;

[0057] The support ball 130 is spherical, and the scraper rod 140 is fixed to the outer wall of the support ball 130. There are multiple scraper rods 140, which are evenly distributed on the outer wall of the support ball 130.

[0058] The liquid-absorbing ball 120 is in the shape of an oblate sphere with a hollow interior. The surface of the liquid-absorbing ball 120 has a plurality of water-absorbing holes, which are evenly spaced. Both the support ball 130 and the scraper rod 140 are located inside the liquid-absorbing ball 120. One end of the scraper rod 140 away from the support ball 130 is fixed to the inner wall of the liquid-absorbing ball 120.

[0059] The liquid absorbing ball 120 is made of rubber;

[0060] The axis of the rotating rod 110 passes through the center of the supporting ball 130, the axis of the rotating rod 110 is perpendicular to the axis of the liquid absorbing ball 120, and one end of the rotating rod 110 away from the fixed cover 220 is fixed to the outer wall of the liquid absorbing ball 120;

[0061] The rotating rod 110 and the fixing cover 220 are connected by gluing.

[0062] When in use, unscrew the fixed cover 220, and pry open the adhesive connection between the rotating rod 110 and the fixed cover 220. The user holds the rotating rod 110, puts the liquid absorption ball 120 into the mouth, and rotates the rotating rod 110. During the rotation of the rotating rod 110, the liquid absorption ball 120 will be twisted to deform the liquid absorption ball 120, and the gas inside will be squeezed out, and the internal scraper 140 will protrude, stimulating the user's oral cavity and tongue, and promoting the content of exfoliated cells in the user's oral cavity and the secretion of saliva. After the rotating rod 110 rotates in the opposite direction after rotation, the liquid absorption ball 120 is not subjected to force and resets through its own elasticity. During the reset process, negative pressure is generated inside, and the saliva in the user's oral cavity is sucked into the liquid absorption ball 120; at the same time, a preservation solution is added to the storage tube 210, and the sampled liquid absorption ball 120 and the rotating rod 110 are placed in the preservation solution of the storage tube 210, and the fixed cover 220 is screwed on.

[0063] Compared with the prior art, during use, the internal structure of the scraping device is optimized, the production process and procedure are simplified, and the production efficiency and cost are improved. At the same time, by softening the absorbent ball 120 as a whole, when the rotating rod 110 is rotated, the protrusion effect of the scraper rod 140 is more obvious, which can improve the shedding of cells in the user's oral cavity. When the absorbent ball 120 is deformed by the force of the rotating rod 110, the internal cavity volume becomes smaller. During the resetting process, negative pressure can be generated, thereby improving the effect of absorbing saliva. The oblate spheroid-shaped absorbent ball 120 can be more convenient for the user to put into the mouth.

[0064] Embodiment 2: Embodiment 1 When in use, the liquid absorbing ball 120 is deformed, and negative pressure can be generated inside the liquid absorbing ball 120 during its reset process, so as to absorb the external saliva. The negative pressure generated by the liquid absorbing ball 120 being deformed alone is small, and the saliva absorbed is small, and the efficiency is poor. Based on this, the solution of embodiment 1 is improved, such as Figure 5-Figure 7 As shown:

[0065] The support ball 130 is hollow inside and made of rubber;

[0066] The scraping assembly 100 further includes an air filling tube 150;

[0067] The inflation tube 150 is located in the liquid absorbing ball 120, and one end of the inflation tube 150 is fixed on the supporting ball 130, and the inflation tube 150 and the supporting ball 130 are connected;

[0068] The rotating rod 110 is cylindrical along its axis, and one end of the inflation tube 150 away from the supporting ball 130 passes through the outer wall of the liquid absorbing ball 120 and communicates with the hollow cavity of the rotating rod 110;

[0069] When in use, one end of the rotating rod 110 away from the liquid absorbing ball 120 is externally connected to a detachable air source.

[0070] During use, when the patient puts the absorbent ball 120 into the mouth, the air source connected to one end of the rotating rod 110 is used to inflate the support ball 130, causing the support ball 130 to expand. During the expansion process, the gas inside the absorbent ball 120 is squeezed out, and at the same time, the scraper rod 140 can be made more protruding. When the air source draws air outward to restore the support ball 130, the negative pressure sucks the saliva in the mouth.

[0071] During the expansion of the support ball 130, the scraper rod 140 can be made more protruding, thereby increasing the content of exfoliated cells in the saliva sample. At the same time, during the process of the support ball 130 shrinking after expansion, negative pressure is generated inside the suction ball 120, which will suck the saliva in the oral cavity and improve the efficiency and success rate of saliva sampling.

[0072] Embodiment 3: When the embodiment 2 is used, the saliva in the user's oral cavity is collected by the liquid absorption ball 120. However, in the process of saliva production, a large amount of saliva will gather on both sides of the user's oral cavity. The efficiency of collecting the internal saliva by relying on a single liquid absorption ball 120 is low and inconvenient to operate. Based on this, the solution of the embodiment 2 is improved, such as Figure 8 As shown:

[0073] There are two scraping components 100, and the two scraping components 100 are symmetrically arranged in a V shape;

[0074] The ends of the rotating rods 110 in the two scraping assemblies 100 away from the liquid absorbing balls 120 are fixed to each other;

[0075] The two liquid-absorbing balls 120 in the scraping components 100 are arranged opposite to each other with the largest outer circles being circular in cross section;

[0076] The rotating rod 110 is made of a bendable material.

[0077] During use, the user can pinch the rotating rod 110 with his hands to bring the two scraping components 100 closer to each other, and the two liquid absorbing balls 120 can be fitted and overlapped and then enter the patient's mouth. The support ball 130 can be inflated by an air source connected to one end of the rotating rod 110 to expand the support ball 130. During the expansion process, the gas inside the liquid absorbing ball 120 is squeezed out, and at the same time, the scraping rod 140 can be made more protruding to scrape the inside of the patient's mouth. When the air source draws air outwards to restore the support ball 130, the negative pressure sucks the saliva in the mouth; the two scraping components 100 can be in the initial V shape and put into the patient. At the place where saliva gathers on both sides of the patient's mouth, the support ball 130 is inflated by an external air source at one end of the rotating rod 110, so that the support ball 130 expands. During the expansion process, the gas inside the liquid-absorbing ball 120 is squeezed out, and at the same time, the scraper rod 140 can be made more protruding, so as to scrape the two sides of the patient's mouth. When the air source draws air outward to restore the support ball 130, the negative pressure sucks in the saliva gathered on both sides of the mouth. When the two scraping components 100 are placed in the user's mouth in a V shape, the two rotating rods 110 can be pressed so that the liquid-absorbing ball 120 can press on both sides of the user's tongue to promote the production of saliva.

[0078] The two scraping components 100 can be placed in a V-shape on both sides of the user's mouth. During the forward and backward movement, the saliva gathered on both sides of the user's mouth can be collected, and the two sides of the mouth can be stimulated at the same time to improve the efficiency of saliva production and collection. At the same time, when the two scraping components 100 are placed in a V-shape on both sides of the user's mouth, the two rotating rods 110 can be pressed so that the absorbent balls 120 can press on both sides of the user's tongue to increase the production and collection of saliva; expand the stimulation area, and at the same time, the width of the placement can be adjusted according to the size of the user's mouth to adapt to the mouth size of different users.

[0079] Embodiment 4: When the embodiment 3 is used, the two scraping components 100 are used to stimulate the user's oral cavity and collect saliva. During the stimulation process, the contact area between one end of the scraper rod 140 and the user's oral cavity is small, and the stimulation effect is poor. At the same time, when the cells and saliva on the user's tongue are absorbed by the liquid absorption ball 120, the efficiency is poor and it needs to be repeated many times. Based on this, the solution of embodiment 3 is improved, such as Fig. 9 As shown:

[0080] Also included is a gathering assembly 300, wherein the gathering assembly 300 includes a scraping rope 310 and an absorption rope 320;

[0081] The two ends of the scraping rope 310 and the absorption rope 320 correspond to the two liquid absorbing balls 120 in the scraping assembly 100 respectively;

[0082] The two ends of the scraping rope 310 are respectively fixed to the sides of the liquid absorbing balls 120 in the two scraping assemblies 100 close to each other;

[0083] The two ends of the absorption rope 320 are respectively fixed to the sides of the liquid absorbing balls 120 in the two scraping assemblies 100 close to each other, and the absorption rope 320 is located on the side of the scraping rope 310 close to the rotating rod 110;

[0084] The scraping rope 310 is made of rubber, and the absorption rope 320 is made of cotton thread;

[0085] In the initial state, the scraping rope 310 and the absorption rope 320 are in a stress-free state.

[0086] When the two scraping components 100 are placed in a V-shape on both sides of the user's mouth, the scraping rope 310 and the absorption rope 320 are located on the upper side of the user's tongue. During the forward and backward movement of the two scraping components 100, the scraping rope 310 and the absorption rope 320 can stimulate the upper side of the user's tongue, and at the same time, the cells and saliva can be scraped off. The absorption rope 320 can also absorb saliva during the scraping process. The scraped saliva will flow along the scraping rope 310 and the absorption rope 320 to both sides of the user's mouth and gather. After the collection is completed, the rotating rods 110 of the two scraping components 100 can be pinched to squeeze the two absorbent balls 120 against the absorption rope 320 between them to squeeze out the saliva in the absorption rope 320.

[0087] By adding the scraping rope 310 and the absorption rope 320, during use, the contact area with the user's tongue can be increased, the stimulation area of ​​the tongue can be increased, and the cells and saliva on the surface of the user's tongue can be gathered and collected by scraping, thereby improving the efficiency of collecting the user's saliva; at the same time, the absorption rope 320 can absorb the salivary cells during the scraping process, thereby improving the success rate of sampling.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
