Description

TECHNICAL FIELD

[0001] The present application relates to the field of pediatric medical technology, in particular to a tongue depressor for children. BACKGROUND

[0002] Tongue depressors are commonly used medical devices for clinical examination of the throat and oral cavity, by depressing the tongue to expose the throat area. For children, an ideal tongue depressor should minimize the gag reflex and resistance while effectively depressing the tongue.

[0003] A tongue depressor for children is disclosed in publication CN106963329A, which comprises a handle and a pressure plate. The pressure plate is arranged at the front end of the handle, and the angle between the pressure plate and the handle is 100°-135°. The lower end of the pressure plate is provided with an arc-shaped protrusion. The pressure plate is a transparent hollow structure, and the inner cavity side arm of the pressure plate is provided with a plurality of functional cavity beads. The bottom of the handle is provided with a battery compartment, and the battery compartment is provided with a storage battery. A first switch is arranged on the handle, and the storage battery is electrically connected with the first switch and the functional cavity beads. A magnifying glass is arranged at the junction of the handle and the pressure plate. The invention has the advantages of simple structure, convenient use, and clear observation of the internal condition of the child's oral cavity, which improves the examination efficiency of medical personnel.

[0004] Although the angle between the pressure plate and the handle of the invention can adapt to the angle of the child's oral cavity to a certain extent, it still has the following defects: first, the traditional tongue depressor lacks a pressure sensing and feedback mechanism when it is deep into the oral cavity. When the sensitive area of the tongue root is touched and the gag reflex is triggered, it is difficult to quickly relieve the child's discomfort by relying only on the experience of medical personnel to adjust the angle of force. Especially for children with sensitive throats, it is easy to induce severe coughing and even resistance to examination, which prolongs the diagnosis and treatment time. Second, the existing technology realizes negative pressure fixation by setting adsorption holes at the bottom of the pressure plate, but the single channel design leads to uneven distribution of negative pressure, and the hard material cannot adapt to the curvature of the tongue surface, which is easy to cause local air leakage failure. When the child's tongue frequently crawls due to tension, the pressure plate is easy to deviate and fall off, which needs to be adjusted repeatedly, affecting the examination efficiency. In addition, although the tongue depressor for children disclosed in publication CN106963329A can adapt to the angle of the child's oral cavity to a certain extent, the angle is always fixed and cannot be adaptively adjusted according to the dynamic tongue. SUMMARY

[0005] To solve the above problems, the present application provides a tongue depressor for children, which can effectively improve the comfort of diagnosis and treatment by sensing the child's gag reflex in real time and delivering syrup to relieve the gag reflex during oral examination.

[0006] In order to achieve the above object, the technical scheme of the present application is as follows: A tongue depressor for children comprises a handle and a pressing plate, the handle and the pressing plate are hingedly connected to each other, a drainage cavity is arranged on one side of the pressing plate close to the handle, a plurality of negative pressure holes are formed in the bottom of the side of the pressing plate away from the drainage cavity, a Y-shaped shunt passage is arranged in the pressing plate, the shunt passage comprises a main passage and symmetrically arranged auxiliary passages, the negative pressure holes are in communication with the auxiliary passages, and the side walls of the pressing plate, the main passage and the auxiliary passages are all made of elastic silica gel film;

[0007] An induction assembly for inducing whether the tongue is in normal swallowing or foreign matter induced vomiting reflex is arranged in the main passage, a syrup storage bag is detachably connected to the side of the handle away from the pressing plate, a delivery assembly for automatically delivering syrup into the mouth of the child to reduce rejection when the induction assembly senses that the child has vomiting reflex is arranged in communication with the syrup storage bag, and one end of the delivery assembly away from the syrup storage bag is in communication with the drainage cavity.

[0008] The induction assembly comprises an elastic diaphragm fixedly connected to the inner wall of the main passage, the pressing plate and the handle are provided with a movable passage in communication with each other, a first rack is fixedly connected to the side of the elastic diaphragm away from the auxiliary passage, the first rack extends into the movable passage and is engaged with a sector tooth, the sector tooth is rotatably connected to the inner side wall of the movable passage, a second rack is further engaged with the sector tooth, a valve core is fixedly connected to one end of the second rack away from the sector tooth, a first spring is fixedly connected to the side of the valve core away from the second rack, and the top end of the first spring is fixedly connected to the inner wall of the movable passage.

[0009] The technical principle of the above scheme is as follows:

[0010] The hinged structure allows the handle and the pressing plate to form a variable included angle, which is convenient for adapting to the oral anatomical features of children of different ages, when the pressing plate lightly touches the tongue surface, the tongue is subconsciously lifted, which causes the main passage to be squeezed and deformed, forcing the airflow to pass through the auxiliary passage to form negative pressure adsorption, and the elastic deformation of the silica gel material automatically fits the curvature of the tongue surface.

[0011] When the child has normal swallowing action, the tongue body produces intermittent low pressure on the pressing plate for a short time, at this time, the slight deformation of the elastic diaphragm is not enough to overcome the spring pre-tightening force to trigger the displacement of the valve core through the rack-sector tooth transmission mechanism. When the foreign matter stimulates the vomiting reflex, the violent contraction of the tongue root produces continuous high pressure, which is transmitted to the main passage through the silica gel film wall, the negative pressure in the auxiliary passage increases, the elastic diaphragm is deformed significantly, the linear motion of the first rack drives the rotation of the sector tooth, and then drives the second rack to overcome the spring resistance to push the valve core to move axially, so that the syrup flows to the delivery assembly and then enters the child's mouth from the drainage cavity.

[0012] The above scheme has the following beneficial effects:

[0013] 1、This scheme, based on the linkage of elastic diaphragm and the negative pressure generated in the main channel and the secondary channel, realizes the accurate distinction of the pressure mode of the tongue. When the child produces persistent high pressure due to foreign body stimulation, the deformation amount of the elastic diaphragm breaks through the critical threshold, triggering the displacement of the valve core through the mechanical amplification effect of the rack and pinion, ensuring the instantaneity and accuracy of the syrup delivery. This process does not require external power supply, completely relying on the biomechanical characteristics to realize closed-loop control, avoiding the complex structure of electronic sensing, and improving the reliability of medical operation.

[0014] 2、This scheme, the hinge type connection with the elastic silica gel film constitutes the pressure plate main body, when the tongue is lifted, the airflow acceleration effect generated by the deformation of the main channel causes the secondary channel to form a self-adaptive negative pressure adsorption, making the negative pressure hole dynamically fit the curvature of the tongue surface, which not only maintains the positioning stability of the pressure plate, but also avoids the local compression damage of the traditional hard tongue depressor to the mucosa.

[0015] 3、This scheme, the design of the syrup storage capsule and the delivery assembly, can automatically deliver syrup into the child's mouth when the child vomits, effectively reducing the child's rejection and discomfort, so that the examination can be smoothly carried out.

[0016] Further, the turning point of the movable channel corresponds to the hinge between the handle and the pressure plate, the fan teeth are rotationally connected to the turning point of the movable channel, one end of the movable channel located in the handle penetrates the communication between the delivery assembly and the syrup storage capsule, and the valve core is used to block the communication channel between the delivery assembly and the syrup storage capsule in the normal state.

[0017] Beneficial effect: When the angle between the pressure plate and the handle changes, the movable channel rotates synchronously with the hinge point, keeping the rack and pinion engagement state constant. The valve core normally blocks the communication channel between the delivery assembly and the storage capsule, preventing spontaneous leakage of syrup.

[0018] Further, the hinge between the handle and the pressure plate is provided with a locking assembly, the locking assembly includes a hinge shaft and a ratchet disc symmetrically arranged at both ends of the hinge shaft, the hinge shaft is rotationally connected to the inner side wall of the pressure plate at both ends, the handle is provided with elastic buckles on both sides, the front end of each elastic buckle is provided with a pawl engaged with the inclined teeth of the ratchet disc, and the inner side wall of the handle is provided with a release assembly corresponding to the elastic buckles and used for manually releasing the lock, and the pawls are hingedly connected to one end of the release assembly.

[0019] Beneficial effect: According to the opening degree of the child's oral cavity, the ratchet can automatically adapt to the angle of the child's tongue, and the self-locking effect of the inclined surface of the pawl and the inclined teeth ensures that the pressure plate maintains a constant angle under the resistance of the tongue.

[0020] Further, the releasing assembly each comprises a support fixedly connected to the inner bottom wall at both sides of the handle and a push rod hingedly connected to the support, the push rod is provided with a second spring and a third spring fixedly connected to both sides of the support at the bottom, the second spring and the third spring are each fixedly connected to the inner bottom wall of the handle at the end away from the push rod, the pawl is hingedly connected to the end of the push rod inside the handle, the other end of the push rod extends to the outside of the handle through the handle and is fixedly connected with a pressing portion, and the handle is provided with a sliding groove on both sides in the movement track of the push rod.

[0021] Beneficial effects: the second spring and the third spring arranged symmetrically form a lever system, when the pressing portion is pressed down under force, the second spring is compressed with the pressing portion, the end of the push rod away from the pressing portion is lifted up, the pawl is obliquely separated from the ratchet disc, the contact of the pawl with the ratchet disc is locked, the medical staff can manually reset the pressing plate, after resetting, the pressing portion is released, the pawl can continue to lock the ratchet disc, and the abrasion of the pressing plate caused by the continuous rotation of the pressing plate due to accidents during daily storage is avoided, and the service life of the tongue depressor is affected.

[0022] Further, the delivery assembly comprises a delivery tube, the delivery tube is communicated with the syrup storage bag and the drainage cavity respectively, the valve core is vertically and slidingly connected to the communication position of the syrup storage bag and the delivery tube, and the drainage cavity is provided with a liquid outlet hole communicated with the outside of the pressing plate.

[0023] Beneficial effects: the syrup can be delivered from the syrup storage bag to the delivery tube through the delivery tube, and then discharged from the liquid outlet hole of the drainage cavity into the mouth of the child, when the tongue pressure changes due to the difference in the intensity of the vomiting reflex of the child, the opening degree of the valve core is automatically adjusted, so that the syrup flow is proportional to the stimulation intensity.

[0024] Further, a filter screen is arranged at the sliding connection position of the delivery tube and the valve core.

[0025] Beneficial effects: the filter screen can filter the impurities in the syrup, so that the impurities are prevented from accumulating in the delivery tube and causing blockage of the delivery tube, and the inspection efficiency is reduced.

[0026] Further, a one-way valve is arranged at the communication position of the drainage cavity and the delivery tube.

[0027] Beneficial effects: the one-way valve can effectively prevent the oral secretions or residual drug solution from flowing into the delivery tube in the reverse direction.

[0028] Further, an anti-slip layer is sleeved on the outer side wall of the end of the handle away from the pressing plate.

[0029] Beneficial effects: the anti-slip layer can increase the friction coefficient of the surface of the handle, so that the medical staff can hold the handle more stably and the handle is not easy to slip off.

[0030] Further, an observation window corresponding to the position of the syrup storage bag is arranged on the handle, and capacity graduation lines are etched on the observation window.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The following detailed description illustrates the specific implementation method:

[0045] Example 1:

[0046] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A child tongue depressor includes a handle 6 and a depressor plate 1. The depressor plate 1 is ice cream shaped to increase fun and reduce children's resistance during oral examinations. At the same time, since traditional tongue depressors are only straight pieces, they cannot conform to the curvature of a child's tongue and are easy to slide. Medical staff need to apply continuous pressure and repeatedly adjust the position, which can easily cause children's gag reflex and affect the efficiency of the examination. Therefore, by setting the handle 6 and the depressor plate 1 to be hinged to each other, the side of the depressor plate 1 near the handle 6 has an integrally formed drainage cavity 19.

[0047] Meanwhile, since the children themselves have poor self-control during the examination, the tongue is easy to move around, and the tongue depressor cannot be placed on the child's tongue more stably, which affects the medical staff to check the throat condition, the bottom of the side of the pressing plate 1 away from the drainage cavity 19 is provided with a plurality of negative pressure holes 2, the pressing plate 1 is integrally formed with a Y-shaped shunt channel, the shunt channel includes a main channel 20 and a symmetrically arranged auxiliary channel 21, the negative pressure holes 2 are in communication with the auxiliary channel 21, the side walls of the pressing plate 1, the main channel 20 and the auxiliary channel 21 are all made of elastic silica gel film, when the pressing plate 1 touches the tongue surface, the child's subconscious tongue will make the main channel 20 be extruded and deformed, forcing the airflow to pass through the auxiliary channel 21 to form negative pressure adsorption, and the elastic deformation of the silica gel material makes the negative pressure holes 2 automatically fit the curvature of the tongue surface.

[0048] Since the tongue depressor easily touches the sensitive area of the tongue root when it enters the deep oral cavity, causing the child to vomit reflex, the main channel 20 is provided with a sensing assembly for sensing whether the tongue is normal swallowing or foreign body induced vomiting reflex, and the side of the handle 6 away from the pressing plate 1 is detachably connected with a syrup storage bag, and the syrup storage bag is communicated with a delivery assembly for automatically delivering syrup into the child's mouth to reduce rejection when the sensing assembly senses that the child has a vomiting reflex, when the child normally swallows during the examination, the sensing assembly is not triggered, when the child has a vomiting reflex, the sensing assembly triggers the delivery assembly and releases the syrup in the syrup storage bag into the child's mouth, relieving the urge to vomit.

[0049] Specifically, the delivery assembly includes a delivery tube, the delivery tube is in communication with the syrup storage bag and the drainage cavity 19 respectively, a one-way valve is bolted at the communication position of the drainage cavity 19 and the delivery tube, the one-way valve arranged in the drainage cavity 19 can ensure that the syrup delivered by the delivery tube to the drainage cavity 19 will not flow back to the delivery tube, and also prevent the child's saliva from entering the drainage cavity 19 and then accumulating into the delivery tube, the side wall of the drainage cavity 19 is provided with a liquid outlet hole 3 in communication with the outside of the pressing plate 1.

[0050] The inductive assembly comprises an elastic diaphragm 22 bonded to the inner wall of the main channel 20, the pressing plate 1 and the handle 6 are provided with a movable channel 24 in communication with each other, the elastic diaphragm 22 is bonded with a first rack 23 on the side away from the auxiliary channel 21, the first rack 23 extends into the movable channel 24 and is engaged with a sector gear 25, the turning position of the movable channel 24 corresponds to the hinge position between the handle 6 and the pressing plate 1, one end of the movable channel 24 in the handle 6 penetrates the infusion tube and communicates with the communication position of the syrup storage bag, the sector gear 25 is rotationally connected to the turning position of the movable channel 24, the sector gear 25 is further engaged with a second rack 17, one end of the second rack 17 away from the sector gear 25 is welded with a valve core 16, the valve core 16 is vertically and slidingly connected to the communication position of the syrup storage bag and the infusion tube, the side of the valve core 16 away from the second rack 17 is welded with a first spring 15, the top end of the first spring 15 is welded with the inner wall of the movable channel 24, and the valve core 16 is used for blocking the communication channel between the infusion tube and the syrup storage bag in the normal state, and the filter screen is bonded to the sliding connection position between the infusion tube and the valve core 16.

[0051] When the child cooperates with the examination to regularly swallow, the tongue body exerts periodic pressure on the silica gel wall of the main channel 20, at this time, the negative pressure in the auxiliary channel 21 tends to be stable, the elastic diaphragm 22 does not deform, so that the first rack 23 and the second rack 17 remain in the reset state, and the valve core 16 blocks the channel of the syrup storage bag. When the pressing plate 1 touches the root of the tongue to trigger the vomiting reflex, the tongue body will vibrate at a high frequency, at this time, the main channel 20 is pressed more, so that the negative pressure in the auxiliary channel 21 increases, causing the elastic diaphragm 22 to deform and recess into the main channel 20, the displacement of the elastic diaphragm 22 drives the first rack 23 to displace towards the end close to the sector gear 25, a part of the sector gear 25 engages with the first rack 23, pushes the rotation, and further drives the second rack 17 to displace towards the end close to the valve core 16, the transmission ratio between the first rack 23 and the second rack 17 is adjusted by the radius of the sector gear 25, the force is amplified, so that even if the tongue pressure is small, the displacement of the valve core 16 can be triggered, and at the same time, since the tongue pressing plate itself is narrow in space, a compact structure is required, if a connecting rod mechanism is used, multiple hinge points are required, which can cause the connecting rod to be easily jammed in the handle 6 or the pressing plate 1, and the first rack 23, the second rack 17 and the sector gear 25 can transmit motion and change the direction of force in the limited space.

[0052] At this time, the valve core 16 is pushed away from the communication position between the infusion tube and the syrup storage bag, and presses the first spring 15, after the syrup in the syrup storage bag is pumped out, filtered through the filter screen, and enters the drainage cavity 19 along the infusion tube, the filter screen can filter impurities in the syrup to avoid blocking the infusion tube, the syrup is discharged to the child's mouth through the liquid outlet hole 3 on the drainage cavity 19, the sweet taste of the syrup stimulates the taste buds to increase the amount of saliva secretion, and neutralizes the vomiting impulse through the swallowing reflex.

[0053] When the swallowing of the child tends to be stable, the negative pressure in the auxiliary channel 21 is reduced, the elastic diaphragm 22 is reset, and at the same time, the valve core 16 is closed under the reset thrust of the first spring 15, and the first rack 23 is pushed to assist the elastic diaphragm 22 to reset.

[0054] Embodiment 2:

[0055] As shown in the accompanying Figure 1 , Figure 2 and Figure 3 , the difference from embodiment 1 is that the hinge of the handle 6 and the pressing plate 1 is provided with a locking assembly, which includes a hinge shaft 18 and a ratchet disc 10 symmetrically arranged at both ends of the hinge shaft 18, and the both ends of the hinge shaft 18 are respectively rotatably connected with the inner side wall of the pressing plate 1. The both sides of the handle 6 are respectively rotatably connected with elastic buckles, and the front ends of the elastic buckles are integrally formed with pawls 11 which are engaged with the inclined teeth of the ratchet disc 10. The inner side wall of the handle 6 is provided with a release assembly corresponding to the elastic buckles and used for manually releasing the locking, and the pawls 11 are hingedly connected to one end of the release assembly.

[0056] The release assembly includes a support 14 welded to the inner bottom wall of the handle 6 at both sides and a push rod 12 hingedly connected to the support 14. The push rod 12 is respectively welded with a second spring 13 and a third spring at both sides of the support 14. The second spring 13 and the third spring are respectively welded to the inner bottom wall of the handle 6 away from the push rod 12. The pawls 11 are hingedly connected to one end of the push rod 12 inside the handle 6. The other end of the push rod 12 extends to the outside of the handle 6 through the handle 6 and is integrally formed with a pressing portion 5. The both sides of the handle 6 are respectively provided with a sliding groove 4 located on the movement track of the push rod 12.

[0057] The specific implementation process is as follows: in order to make the pressing plate 1 conform to the angle of the tongue in the oral cavity of the child, after the tongue depressor is put into the oral cavity of the child, the tongue is pressed downward by the pressing plate 1, the hinge shaft 18 drives the ratchet disc 10 to rotate clockwise, the inclined teeth on the ratchet disc 10 push the wedge surface of the pawl 11, the pawl 11 is extruded by the inclined teeth to make the elastic buckle elastically bend outward until the pawl 11 slides into the next inclined tooth slot. When the pressing plate 1 tends to be stable, the pressing plate 1 is locked at the current angle by the pawl 11 and cannot be lifted upward by the tongue. When the pressing plate 1 needs to be reset after the examination is completed, the medical staff press the pressing portions 5 on both sides of the handle 6 at the same time, the push rod 12 rotates around the support 14, the elastic buckle at the bottom is pulled up, the elastic buckle drives the pawl 11 to be obliquely disengaged from the engagement position of the inclined teeth of the ratchet disc 10, the pressing plate 1 is reset to the initial angle under the manual operation of the medical staff, and at the same time, the pressing portions 5 are released, so that the pawl 11 is re-engaged into the inclined teeth of the ratchet disc 10 to engage, so that the pressing plate 1 will not be displaced upward and downward on the handle 6 to increase the abrasion of the hinge position under the action of external force in the normal state.

[0058] Embodiment 3:

[0059] As shown in the accompanyingFigure 1 The difference between the embodiment 2 and the embodiment 3 is that the handle 6 is sleeved with the anti-skid layer 8 on the outer wall of the one end of the pressing plate 1, so as to solve the problem that the traditional smooth handle 6 is easy to slip and affects the detection efficiency.
