Description

Technical Field

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

[0002] Oral sampling is widely used in the diagnosis of respiratory diseases, such as acute upper respiratory tract infections, acute tonsillitis, and acute pharyngitis. By detecting pathogens in the oral cavity, the cause of the disease can be identified, providing strong support for clinical treatment. Traditional sampling methods involve inserting a sterile swab or sampling cotton swab into the mouth, past the base of the tongue to the posterior pharyngeal wall or the posterior side of the uvula, collecting specimens from the swollen area of ​​the nasopharynx or the tonsillar recesses and lateral walls. With the development of technology, more and more oral sampling devices are being used.

[0003] For example, Chinese patent CN214856953U discloses an oral mucosa sampling device. This device allows a sampling rod to be installed in the mounting hole of a connecting rod. The length of the connecting rod within the adjustment hole is adjusted by rotating the connecting rod, ensuring the length of the connecting rod and the holding rod is suitable for sampling. The user holds the holding rod and inserts a cloth into the oral cavity, collecting the sample by rotating and moving the cloth back and forth on the holding rod. After sample collection, the cloth is placed into the sampling tube. An adjustment component moves the holding rod towards the sampling rod, thus pushing the sampling rod into the sampling tube.

[0004] However, when performing oral sampling on patients with cognitive impairment or young children, the patients are unable to cooperate with medical staff to keep their mouths open for a long time, requiring the use of special devices to open the mouth. However, the process of opening the mouth requires the use of multiple tools, which makes it inconvenient to insert the sampling swab. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes an oral sampling device for respiratory tract examination, which solves the technical problem mentioned in the background art: currently, during oral sampling, a special device is needed to open the oral cavity, but multiple tools are required to open the oral cavity, which makes it inconvenient to insert the sampling swab.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oral sampling device for respiratory tract examination, comprising:

[0007] The mounting bracket has a handle at one end;

[0008] A connecting frame, one end of which is hinged to the mounting frame and provided with a handle, and a support frame is arranged opposite to the end of the connecting frame and the mounting frame;

[0009] A housing is disposed between the mounting bracket and the connecting bracket and connected thereto via a connecting assembly, which converts the rotation of the connecting bracket into the sliding of the housing.

[0010] The mounting base is slidably disposed within the housing and connected thereto via a linkage assembly, which converts the sliding of the housing into driving the mounting base to slide within the housing; and

[0011] An installation cylinder is disposed within the mounting base for mounting sampling swabs. The mounting base is provided with a drive mechanism connected to the installation cylinder, which drives the installation cylinder to move along an elliptical trajectory and drives the sampling swabs to rotate.

[0012] In a preferred embodiment, both ends of the support frame are curved surfaces, and both ends of the support frame are fitted with removable protective pads.

[0013] In a preferred embodiment, a first torsion spring is provided at the hinge point between the connecting frame and the mounting frame.

[0014] In a preferred embodiment, the connection component includes:

[0015] Two sets of connecting rods are provided, each set having one end hinged to the mounting bracket and the connecting frame respectively, and the other end hinged to the housing; and

[0016] The second torsion spring is provided in two sets, and is respectively located at the hinge point between the two sets of connecting rods and the housing. The sum of the torques of the two sets of second torsion springs is less than the torque of the first torsion spring.

[0017] In a preferred embodiment, the linkage component includes:

[0018] A drive gear is disposed at the hinge point between one set of the connecting rods and the housing; and

[0019] A rack is mounted on the mounting base and meshes with the drive gear.

[0020] In a preferred embodiment, the drive mechanism includes:

[0021] A servo motor is installed in the mounting base, and a control switch for starting and stopping the servo motor is provided on the handle;

[0022] A mounting plate is disposed on the output shaft of the servo motor, and a sliding groove is provided on the mounting plate;

[0023] A mounting rod is disposed at the end of the mounting cylinder. A slider is rotatably connected to the end of the mounting rod. The slider is slidably disposed within the slide groove. A first elastic element is disposed between the slider and the end of the slide groove near the center of the mounting plate.

[0024] A guide component, disposed on the mounting base and connected to the mounting rod, guides the mounting rod along an elliptical trajectory and drives the mounting rod to rotate.

[0025] In a preferred embodiment, the guiding component includes:

[0026] An elliptical frame is disposed at the end of the mounting base, the mounting rod passes through the elliptical frame, and toothed rings are arranged inside the elliptical frame; and

[0027] A guide wheel is mounted on the mounting rod and secured to the elliptical frame. A guide gear is mounted on the guide wheel and meshes with the gear ring.

[0028] In a preferred embodiment, the mounting tube is provided with a fixing component, which can selectively fix or unfix the sampling swab.

[0029] In a preferred embodiment, the fixing component includes:

[0030] The buttons are provided in two sets, and are slidably disposed inside the mounting cylinder and protrude outwards;

[0031] The mounting bracket has at least two sets, each set connected to one of the two sets of buttons, and the two sets of mounting brackets are stacked to form a cavity for accommodating the sampling swab; and

[0032] A second elastic element is disposed between the two sets of buttons.

[0033] In a preferred embodiment, the end of the mounting bracket facing away from the handle is an inclined surface, which is inclined toward the inside of the cavity formed by the two sets of mounting brackets.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] When using this device, two sets of supports are placed in the patient's mouth and abut against the patient's upper and lower teeth. By gripping the handle, the connecting frame rotates along its hinge point with the mounting frame, thus opening the patient's mouth and preventing the patient from closing their mouth during oral sampling, which would reduce the medical staff's field of vision and improve the convenience of sampling. Furthermore, while controlling the rotation of the connecting frame, the connecting component drives the housing to slide. During this sliding process, the housing also drives the mounting base to slide within the housing via a linkage component, thereby controlling the insertion of the sampling swab into the patient's mouth and making contact. The drive mechanism then controls the mounting cylinder to move along an elliptical trajectory and drives the sampling swab to rotate, ensuring that the circumference of the sampling swab makes uniform contact with the patient's mouth for sampling. This device effectively prevents the patient's mouth from closing during oral sampling and automatically completes the insertion and movement of the sampling swab. Sampling can be performed with one hand, eliminating the need for cumbersome tools and complex procedures, effectively improving the efficiency of oral sampling. Attached Figure Description

[0050] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art 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 at one end of the mounting frame 101, a connecting frame 105 hinged to the mounting frame 101, a grip 103 at one end of the connecting frame 105, and a support frame 106 arranged opposite to the ends of the connecting frame 105 and the mounting frame 101. Both ends of the support frame 106 are curved surfaces, and both ends of the support frame 106 are fitted with removable protective pads 107. A first torsion spring 104 is provided at the hinge point between the connecting frame 105 and the mounting frame 101.

[0053] In use, the device allows two sets of supports 106 to be placed inside the patient's mouth. By gripping the handle 102 and grip 103, the two sets of connecting frames 105 rotate along their hinge points, compressing the first torsion spring 104. This opens the two sets of supports 106, preventing the patient's mouth from closing during sampling and thus avoiding sampling failure. The supports 106 have curved ends to prevent the patient's teeth from detaching, and protective pads 107 protect the patient's teeth. After sampling, the first torsion spring 104 controls the grip 103 and connecting frames 105 to return to their original positions, facilitating the removal of the two sets of supports 106 from the mouth.

[0054] like Figures 1 to 4 As shown, in this embodiment, a housing 201 is provided between the mounting frame 101 and the connecting frame 105. The housing 201 is connected to the mounting frame 101 and the connecting frame 105 through a connecting assembly. The connecting assembly converts the rotation of the connecting frame 105 into the sliding of the housing 201. The connecting assembly includes two sets of connecting rods 202. One end of each set 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 housing 201. A second torsion spring 203 is provided at the hinge point between the two sets of connecting rods 202 and the housing 201. The sum of the torques of the two sets of second torsion springs 203 is less than the torque of the first torsion spring 104.

[0055] When the handle 103 is gripped to open the mounting bracket 101 and the connecting bracket 105, the housing 201 is moved closer to the patient's mouth by the two sets of connecting rods 202. Since the second torsion spring 203 is provided at the hinge of the connecting rod 202 and the housing 201, the housing 201 cannot deflect freely, thus keeping the housing 201 as close as possible to the middle position between the mounting bracket 101 and the connecting bracket 105, and the housing 201 facing between the two sets of support brackets 106.

[0056] like Figures 2 to 5 As shown, in this embodiment, a mounting base 301 is slidably disposed inside the housing 201. The mounting base 301 is connected to the housing 201 through a linkage component. The linkage component converts the sliding of the housing 201 into driving the mounting base 301 to slide inside the housing 201. The linkage component includes a drive gear 204 disposed at the hinge point between one of the connecting rods 202 and the housing 201. A rack 302 is disposed on the mounting base 301, and the rack 302 meshes with the drive gear 204.

[0057] During the movement of the housing 201 by gripping the handle 103, the connecting rod 202 rotates relative to the housing 201. During the rotation, the connecting rod 202 drives the drive gear 204 to rotate on the housing 201. Then, through the cooperation of the drive gear 204 and the rack 302, the mounting base 301 is controlled to slide in the housing 201 towards the direction closer to the mouth.

[0058] like Figures 4 to 6 As shown, in this embodiment, the mounting base 301 is provided with a mounting cylinder 504 for mounting the sampling swab 505. The mounting base 301 is also provided with a drive mechanism connected to the mounting cylinder 504. The drive mechanism drives the mounting cylinder 504 to move along an elliptical trajectory and drives the sampling swab 505 to rotate. When the handle 103 is gripped, causing the housing 201 to move and the mounting base 301 to slide closer to the oral cavity under the action of the linkage component, the movement distance of the sampling swab 505 can be increased, allowing the sampling swab 505 to extend into and contact the patient's oral cavity for sampling.

[0059] like Figures 4 to 6 As shown, in this embodiment, the drive mechanism includes a servo motor 401 disposed in the mounting base 301, a control switch 406 for starting and stopping the servo motor 401 disposed on the handle 102, a mounting plate 402 disposed on the output shaft of the servo motor 401, a groove 403 disposed on the mounting plate 402, a mounting rod 501 disposed at the end of the mounting cylinder 504, a slider 404 rotatably connected to the end of the mounting rod 501, the slider 404 being slidably disposed in the groove 403, a first elastic element 405 disposed between the slider 404 and the end of the groove 403 near the center of the mounting plate 402, and a guide assembly disposed on the mounting base 301 connected to the mounting rod 501, the guide assembly guiding the mounting rod 501 to an elliptical trajectory and driving the mounting rod 501 to rotate. The guide assembly includes an elliptical frame 303 disposed at the end of the mounting base 301, a mounting rod 501 passing through the elliptical frame 303, a toothed ring 304 disposed inside the elliptical frame 303, a guide wheel 503 disposed on the mounting rod 501, the guide wheel 503 being engaged with the elliptical frame 303, and a guide gear 502 disposed on the guide wheel 503, the guide gear 502 meshing with the toothed ring 304.

[0060] Pressing the control switch 406 activates the servo motor 401, causing the mounting plate 402 to rotate. During rotation, the mounting plate 402 drives the mounting rod 501, which in turn moves the sampling swab 505. As the mounting rod 501 moves, the first elastic element 405 controls the slider 404 to always move away from the center of the mounting plate 402. The guide wheel 503, in conjunction with the elliptical frame 303, drives the sampling swab 505 in an elliptical trajectory, allowing it to move slowly along the patient's oral cavity. In some embodiments, the elliptical frame 303 can be designed in other shapes, ensuring the sampling swab 505 remains in contact with the patient's oral cavity during movement for oral sampling. Furthermore, during the elliptical trajectory of the mounting rod 501, the meshing of the guide gear 502 and the toothed ring 304 causes the sampling swab 505 to rotate, ensuring the oral mucosa adheres fully to the swab, improving sampling effectiveness.

[0061] like Figure 6 , 7As shown, in this embodiment, a fixing component is provided on the mounting cylinder 504, which can selectively fix or release the sampling swab 505. The fixing component includes two sets of buttons 506, which are slidably disposed inside the mounting cylinder 504 and protrude outwards. Each set of buttons 506 is provided with a fixing bracket 507, and every two sets of fixing brackets 507 are stacked to form a cavity for accommodating the sampling swab 505. A second elastic element 508 is provided between the two sets of buttons 506. The end of the fixing bracket 507 facing away from the handle 102 is inclined, and the inclined surface is inclined to the inside of the cavity formed by the two sets of fixing brackets 507.

[0062] The second elastic element 508 controls the two sets of buttons 506 to move in opposite directions, thereby reducing the cavity formed by the two sets of fixing brackets 507 to fix the sampling swab 505. After sampling, pressing the two sets of buttons 506 will increase the cavity formed by the two sets of fixing brackets 507, making it easier to remove the sampling swab 505. Inserting the sampling swab 505 into the installation tube 504 allows the sampling swab 505 to push the inclined surfaces of the two sets of fixing brackets 507, causing the two sets of buttons 506 to close. Under the action of the second elastic element 508, the two sets of buttons 506 will separate, thus facilitating the quick and easy installation of the sampling swab 505 and effectively improving the efficiency of oral sampling.

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

[0064] In use, the device involves placing two sets of supports 106 into the patient's mouth, where they abut against the patient's upper and lower teeth. By gripping the handle 103, the connecting frame 105 rotates along its hinge point with the mounting frame 101, thus opening the patient's mouth and preventing the patient's mouth from closing during oral sampling, which would reduce the medical staff's field of vision and improve sampling convenience. Furthermore, while controlling the rotation of the connecting frame 105, the housing 201 can be driven to slide via the connecting component. During the sliding process, the housing 201 can also drive the mounting base 301 via the linkage component. The device slides inward, controlling the insertion of the sampling swab 505 into the patient's mouth. A drive mechanism then controls the installation cylinder 504 to move along an elliptical trajectory and drives the sampling swab 505 to rotate, ensuring that the circumference of the sampling swab 505 makes uniform contact with the patient's mouth for sampling. This device effectively prevents the patient's mouth from closing during oral sampling and automatically completes the insertion and movement of the sampling swab 505. Sampling can be performed with one hand, eliminating the need for cumbersome tools and complex procedures, thus significantly improving the efficiency of oral sampling.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
