Description

Technical Field

[0001] The present invention specifically relates to an oral sampling device for respiratory tract examination. Background Art

[0002] Oral sampling is widely used in the diagnosis of respiratory diseases, such as acute upper respiratory tract infection, acute tonsillitis, acute pharyngitis, etc. By detecting pathogens in the oral cavity, the cause of the disease can be identified, providing strong support for clinical treatment. The traditional sampling method is to use a sterile swab or sampling cotton swab to enter the mouth, pass the root of the tongue to the posterior wall of the pharynx or the back of the uvula, and collect specimens from the red and swollen nasopharynx or the tonsil crypts, side walls, etc. With the development of science and technology, more and more oral sampling devices are put into use.

[0003] For example, the Chinese patent with publication number CN214856953U provides an oral mucosal sampling device, which can install the sampling stick in the mounting hole of the connecting rod; rotate the connecting rod to adjust the length of the sampling stick entering the adjustment hole, so that the length of the connecting rod and the holding rod after connection is suitable for sampling. Hold the holding rod and put the cloth head into the oral cavity, and use the holding rod to rotate the cloth head and move it back and forth to collect the sample. After the sample is collected, put the cloth head into the sampling tube, and drive the holding rod to move to the side of the sampling stick through the adjustment component, and then push the sampling stick into the sampling tube.

[0004] However, when taking oral samples from patients with cognitive impairments or younger children, the patients are unable to cooperate with medical staff to keep their mouths open for a long time, and special devices are needed to open the mouth. However, multiple tools are required in the process of opening the mouth, which makes it inconvenient to insert the sampling swab. Summary of the invention

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0051] Example:

[0052] like Figures 1 to 3 As shown, the present invention provides an oral sampling device for respiratory tract examination, including a mounting frame 101, a handle 102 is provided at one end of the mounting frame 101, a connecting frame 105 is hinged on the mounting frame 101, a grip 103 is provided at the end of the connecting frame 105, a support frame 106 is arranged opposite to the ends of the connecting frame 105 and the mounting frame 101, both ends of the support frame 106 are arc surfaces, and both ends of the support frame 106 are sleeved with a detachable protective pad 107. A first torsion spring 104 is provided at the hinge point between the connecting frame 105 and the mounting frame 101.

[0053] When the device is in use, two sets of support frames 106 can be placed in the patient's oral cavity. By holding the handle 102 and the grip 103, the two sets of connecting frames 105 can be driven to rotate along their hinge points and compress the first torsion spring 104, so that the two sets of support frames 106 are opened to open the patient's oral cavity, thereby preventing the patient's mouth from closing during oral sampling and causing sampling failure. In addition, curved surfaces are provided at both ends of the support frame 106 to prevent the patient's teeth from detaching from the support frame 106, and a protective pad 107 is provided to protect the patient's teeth. After the sampling is completed, the grip 103 and the connecting frame 105 can be controlled to reset under the action of the first torsion spring 104, so that the two sets of support frames 106 can be conveniently taken out of the oral cavity.

[0054] like Figures 1 to 4 As shown, in this embodiment, a shell 201 is arranged between the mounting frame 101 and the connecting frame 105, and the shell 201 is connected to the mounting frame 101 and the connecting frame 105 through a connecting assembly, and the rotation of the connecting frame 105 is converted into driving the shell 201 to slide through the connecting assembly. The connecting assembly includes two groups of connecting rods 202, one end of the two groups of connecting rods 202 is hinged to the mounting frame 101 and the connecting frame 105 respectively, and the other end is hinged to the shell 201, and the hinges of the two groups of connecting rods 202 and the shell 201 are both provided with second torsion springs 203, and the sum of the torsion of the two groups of second torsion springs 203 is less than the torsion of the first torsion spring 104.

[0055] When the handle 103 is gripped to open the mounting frame 101 and the connecting frame 105, the shell 201 is driven toward the patient's mouth by the two sets of connecting rods 202. Since a second torsion spring 203 is provided at the hinge between the connecting rod 202 and the shell 201, the shell 201 cannot deflect freely, thereby keeping the shell 201 in the middle position between the mounting frame 101 and the connecting frame 105 as much as possible, and the shell 201 is facing between the two sets of support frames 106.

[0056] like Figures 2 to 5 As shown, in this embodiment, a mounting seat 301 is slidably arranged in the shell 201, and the mounting seat 301 is connected to the shell 201 through a linkage component. The linkage component is used to convert the sliding of the shell 201 into driving the mounting seat 301 to slide in the shell 201. The linkage component includes a driving gear 204 arranged at the hinge between one group of connecting rods 202 and the shell 201, and a rack 302 is arranged on the mounting seat 301, and the rack 302 is meshed with the driving gear 204.

[0057] When the handle 103 is gripped to move the shell 201, the connecting rod 202 and the shell 201 rotate relative to each other. The connecting rod 202 drives the driving gear 204 to rotate on the shell 201 during the rotation, and then controls the mounting seat 301 to slide in the shell 201 toward the oral cavity through the cooperation between the driving gear 204 and the rack 302.

[0058] like Figures 4 to 6 As shown, in this embodiment, a mounting tube 504 for mounting a sampling cotton swab 505 is provided in the mounting seat 301, and a driving mechanism connected to the mounting tube 504 is provided in the mounting seat 301, and the mounting tube 504 is driven by the driving mechanism to move along an elliptical trajectory and drive the sampling cotton swab 505 to rotate. When the housing 201 is moved by gripping the handle 103 and the mounting seat 301 is controlled to slide toward the oral cavity under the action of the linkage component, the movement distance of the sampling cotton swab 505 can be expanded, so that the sampling cotton swab 505 is inserted into the patient's oral cavity and abuts against it, and sampling can be performed.

[0059] like Figures 4 to 6 As shown, in this embodiment, the driving mechanism includes a servo 401 arranged in a mounting seat 301, a control switch 406 for driving the servo 401 to start and stop is arranged on the handle 102, a mounting disk 402 is arranged on the output shaft of the servo 401, a slide groove 403 is opened on the mounting disk 402, a mounting rod 501 is arranged at the end of the mounting cylinder 504, a slider 404 is rotatably connected to the end of the mounting rod 501, the slider 404 is slidably arranged in the slide groove 403, a first elastic member 405 is arranged between the slider 404 and one end of the slide groove 403 close to the center of the mounting disk 402, and a guide assembly connected to the mounting rod 501 is arranged on the mounting seat 301, and the mounting rod 501 is guided by the guide assembly to guide the mounting rod 501 in an elliptical trajectory and drive the mounting rod 501 to rotate. The guide assembly includes an elliptical frame 303 arranged at the end of the mounting seat 301, the mounting rod 501 is inserted into the elliptical frame 303, a gear ring 304 is arranged in the elliptical frame 303, a guide wheel 503 is arranged on the mounting rod 501, the guide wheel 503 is clamped on the elliptical frame 303, a guide gear 502 is arranged on the guide wheel 503, and the guide gear 502 is meshed with the gear ring 304.

[0060] By pressing the control switch 406, the servo 401 is started to drive the mounting plate 402 to rotate. During the rotation of the mounting plate 402, the mounting rod 501 is driven to follow the movement, and the sampling cotton swab 505 is driven to move. During the movement of the mounting rod 501, the slider 404 is controlled by the first elastic member 405 to always move in the direction away from the center of the mounting plate 402, and the sampling cotton swab 505 is driven to move in an elliptical trajectory through the cooperation of the guide wheel 503 and the elliptical frame 303, so that the sampling cotton swab 505 can move slowly along the patient's oral cavity. In addition, in some embodiments, the elliptical frame 303 can also be designed as other shapes, so that the sampling cotton swab 505 can always keep in contact with the patient's oral cavity during the movement, so as to perform oral sampling. In addition, during the movement of the mounting rod 501 in an elliptical trajectory, the sampling cotton swab 505 can also be driven to rotate by the meshing of the guide gear 502 and the gear ring 304, so that the oral mucosa can be fully adhered to the sampling cotton swab 505, thereby improving the sampling effect.

[0061] like Figure 6 , 7As shown, in this embodiment, a fixing assembly is provided on the mounting tube 504, and the sampling cotton swab 505 can be selectively fixed or released by the fixing assembly. The fixing assembly includes two groups of buttons 506, which are relatively slidably arranged in the mounting tube 504 and protrude outward, and the two groups of buttons 506 are provided with fixing frames 507, and each two groups of fixing frames 507 are stacked and arranged to form a cavity for accommodating the sampling cotton swab 505, and a second elastic member 508 is provided between the two groups of buttons 506. The end of the fixing frame 507 facing away from the handle 102 is an inclined surface, and the inclined surface is inclined to the inner side of the cavity formed by the two groups of fixing frames 507.

[0062] The second elastic member 508 controls the two sets of buttons 506 to move in opposite directions, thereby reducing the cavity formed by the two sets of fixing frames 507 to fix the sampling cotton swab 505. After sampling, pressing the two sets of buttons 506 can enlarge the cavity formed by the two sets of fixing frames 507, thereby facilitating the removal of the sampling cotton swab 505. The sampling cotton swab 505 is inserted into the installation cylinder 504, and the sampling cotton swab 505 can push the inclined surfaces of the two sets of fixing frames 507 to close the two sets of buttons 506, and the two sets of buttons 506 are separated under the action of the second elastic member 508, thereby facilitating the rapid installation of the sampling cotton swab 505, thereby effectively improving the efficiency of oral sampling.

[0063] Specific usage and beneficial effects of the present invention:

[0064] When the device is in use, the two sets of support frames 106 are placed in the patient's oral cavity and abut against the patient's upper and lower teeth. The handle 103 is gripped to drive the connecting frame 105 to rotate along the hinge point between the connecting frame 105 and the mounting frame 101, so as to open the patient's oral cavity, thereby preventing the patient's oral cavity from being closed during oral sampling, thereby reducing the field of vision of medical staff, and improving the convenience of sampling. In the process of controlling the rotation of the connecting frame 105, the housing 201 can be driven to slide by the connecting component, and the housing 201 can also drive the mounting seat 301 to slide in the housing 20 through the linkage component during the sliding process. 1, thereby controlling the sampling cotton swab 505 to extend into the patient's oral cavity and contact the oral cavity, and then controlling the mounting cylinder 504 to move along an elliptical trajectory and driving the sampling cotton swab 505 to rotate, so that the circumference of the sampling cotton swab 505 can evenly contact the patient's oral cavity for sampling. The device can effectively prevent the patient's oral cavity from closing during oral sampling, and automatically complete the placement and movement of the sampling cotton swab 505. The sampling work can be performed with one hand without cumbersome tools and complicated procedures, which effectively improves the efficiency of oral sampling.
