TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a clinical examination device special for pediatric internal medicine. BACKGROUND
[0002] Oral cavity detection sampling is to dip the mucosa or tissue cells in the oral cavity with a cotton swab, and then detect and analyze the sample to accurately judge the health of the oral cavity. Oral mucosa refers to the soft and moist tissue covering the inside of the mouth. Generally, it is a barrier that protects the oral cavity. Oral mucosa detection is of great significance because many diseases can be reflected in the early stage through oral mucosa. At the same time, the detection of oral mucosa can also find problems in the immune system.
[0003] The existing oral cavity detection sampling device for pediatric internal medicine is generally directly inserted into the throat of the patient by medical staff for sampling operation. However, small children have poor self-control ability, which may cause the cotton swab to be squeezed by the upper and lower jaws, possibly causing the cotton swab to be bent or even broken. If the broken end is retained in the throat, it needs to be taken out with additional tools, increasing the risk of suffocation. On the other hand, head shaking or tongue movement may cause the cotton swab to deviate from the preset sampling target (such as tonsil crypts, pharyngeal wall follicles). Medical staff need to repeatedly adjust the position of the cotton swab to chase the target, which may cause the tip of the cotton swab to frequently rub the pharyngeal mucosa. Since the pharyngeal mucosa of children is delicate and easy to be scratched, it may cause bleeding or stimulate the epiglottis to cause severe nausea and vomiting, further aggravating the child's resistance. Therefore, we provide a clinical examination device special for pediatric internal medicine to solve the above problems. SUMMARY

[0029] Please refer to Figures 1-8The embodiment provides a clinical examination device special for pediatric internal medicine, which comprises a support frame 1, support plates 4 rotatably connected to both ends of the support frame 1, a connecting block 3 arranged on the inner side of the support frame 1, a first hinge rod 5 arranged between the connecting block 3 and the support plate 4, a threaded rod 2 arranged on the inner side of the support frame 1 and rotatably connected to the connecting block 3, a cotton swab 9 arranged at the front end of the support plate 4, and an auxiliary pushing piece arranged between the cotton swab 9 and the support frame 1 and used for pushing the cotton swab 9 to perform a dipping operation, wherein the auxiliary pushing piece comprises a second connecting pipe 7 arranged on the inner side of the connecting block 3 and a first connecting pipe 6 arranged at the front end of the second connecting pipe 7, an auxiliary docking device arranged between the cotton swab 9 and the first connecting pipe 6 and used for assisting the cotton swab 9 to perform docking installation, and a spherical block 19 embedded at the front end of the second connecting pipe 7, wherein one end of the spherical block 19 is fixedly connected with a connecting column 22, one end of the connecting column 22 is fixedly connected with the first connecting pipe 6, the inner side of the second connecting pipe 7 is provided with a poking assembly used for poking the spherical block 19 to rotate, the poking assembly comprises a pulling rod 16 arranged on the inner side of the second connecting pipe 7, a second hinge rod 17 arranged between the pulling rod 16 and the spherical block 19, two fixed seats 18 rotatably connected with the pulling rod 16 and the spherical block 19 and fixedly connected with the pulling rod 16 and the spherical block 19, a fixed ring 20 fixedly connected with the end of the second connecting pipe 7 and in contact with but not connected with the spherical block 19, an arc-shaped spring 21 arranged between the fixed ring 20 and the connecting column 22, a cover plate 8 fixedly connected with the end of the second connecting pipe 7, a bolt 25 threadedly connected with the inner side of the cover plate 8, a rectangular block 24 slidably connected with the inner side of the second connecting pipe 7, one end of the bolt 25 rotatably connected with the rectangular block 24 through a bearing, the rectangular block 24 fixedly connected with the pulling rod 16, a rectangular groove 23 arranged on the inner side of the second connecting pipe 7 and matched with the rectangular block 24, a threaded groove arranged on the inner side of the cover plate 8 and matched with the bolt 25, and a threaded ring 11 threadedly connected with the outer wall of the first connecting pipe 6, wherein one end of the threaded ring 11 is fixedly connected with a connecting cover 10, and the cotton swab 9 is arranged on the inner side of the connecting cover 10.
[0030] When medical staff needs to dip and sample the throat of a child through a cotton swab, in order to prevent the child from affecting the sampling operation due to lack of self-control, the cotton swab 9 can be inserted into the connecting cover 10, the cotton swab 9 can be shrunk and attached to the inner side of the connecting cover 10 under the extrusion of the cotton itself, then the threaded ring 11 can be screwed on the outer wall of the first connecting pipe 6, so that the cotton swab 9 is installed at the front end of the first connecting pipe 6, and the above steps are directionally operated, so that the staff can take the cotton swab 9 to other places for storage without touching the cotton swab 9.
[0031] When the sampling operation is needed, the staff can select the threaded rod 2 to push the connecting block 3 to move towards the first hinged rod 5, thereby pushing the two support plates 4 to open, and then inserting the two opened support plates 4 into the child's oral cavity to form a support.
[0032] The support plates 4 can actively support the child's upper and lower jaws to form a fixed "oral operation channel". Through the threaded transmission of the threaded rod 2, the medical staff can accurately control the movement distance of the connecting block 3, thereby adjusting the opening angle of the two support plates 4 (such as adjusting to 2-3 cm for children aged 3-6 years old, and adjusting to 3-4 cm for children aged 7-12 years old), ensuring that the channel size is suitable for the oral cavity size of children of different ages, neither too loose to close the channel, nor too tight to compress the oral cavity.
[0033] This design replaces the traditional "medical staff forcibly supporting the child's oral cavity with hands" method, avoids hand blocking the view or causing pain to the child due to uncontrolled force, provides "uninterrupted physical space" for subsequent cotton swab dipping and position adjustment, and fundamentally solves the problem of "oral cavity closing suddenly during sampling";
[0034] The second connecting pipe 7 is only arranged on the inner side of the threaded rod 2 and the connecting block 3 and has no connection relationship with them. When the child's oral cavity is supported by the two support plates 4, the worker pushes the second connecting pipe 7 to drive the cotton swab 9 to move towards the patient's throat, and performs the dipping sampling operation. When the worker needs to adjust the position of the cotton swab 9, the worker can rotate the bolt 25 to push the rectangular block 24 to move forward or backward, thereby pushing the spherical block 19 through the pulling rod 16 and the second hinged rod 17 to drive the first connecting pipe 6 to be raised or pressed downward, and then the worker can rotate the second connecting pipe 7 to adjust the position for scraping operation.
[0035] In the pediatric department throat sampling scene, the independent setting of the second connecting pipe 7 + the multi-dimensional adjustment structure driven by the bolt 25 forms a "stable foundation + flexible adjustment" cooperative system with the oral cavity support structure of the support plate 4, and the core is to solve the key problem of "difficult to accurately adapt to the narrow throat of children after oral fixation", thereby improving the convenience of sampling and improving the overall practicality of the device.

[0037] When the staff operates the second connecting pipe 7 to drive the cotton swab 9 to sample by one hand, the other hand can repeatedly squeeze the resilient bag 27, when the resilient bag 27 is squeezed, the gas in the resilient bag 27 is discharged to the outside through the second one-way valve 28, when the resilient bag 27 is reset under the action of the elastic force, the connecting pipe 12 is suctioned through the first one-way valve 26, and then the outside is suctioned through the guide groove 15, so that the cotton swab 9 is dipped and suctioned at the same time, the sample collection amount is actively improved, the secondary sampling operation caused by insufficient dipping is avoided, the amount of secretion (such as inflammatory exudate and pus point secretion) in the throat of children is usually small and attached to the mucosa surface, the simple cotton swab dipping is easy to cause the sample amount to be insufficient due to "weak secretion adhesion" and "child swallowing reflex", and repeated sampling increases the pain of children, the guide groove 15 is accurately aligned with the outer side of the cotton swab 9, and the negative pressure actively "sucks" the secretion on the mucosa surface of the throat to the cotton head of the cotton swab, especially for a small amount of secretion in deep and hidden areas such as tonsil crypts and pharyngeal wall follicles, the negative pressure can "pull" the secretion to contact the cotton swab, compared with simple dipping (depending on the passive adsorption of the cotton head), so that the collection amount is improved, the sample concentration is higher, and the accuracy of subsequent detection is improved.
