Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary instruments, in particular to an oral tissue sampling and detection device for oral care. Background Art

[0002] The mouth is a channel for eating and breathing. The nutrition and temperature in the mouth are very suitable for the growth and reproduction of bacteria. Improper oral cleaning will cause a series of oral problems. Generally, oral examinations mainly include hard tissue examinations, soft tissue examinations, and teeth examinations. Among the soft tissue sites, the throat is difficult to sample due to conditioned reflexes. Therefore, it is necessary to collect the throat sample last after the samples at other sites are collected. During use, the existing oral tissue sampling devices generally adopt a manual sampling method, and manually use cotton swabs to absorb the patient's saliva or soft and hard tissue samples. During the operation, the patient needs to keep his mouth open for a long time so that the staff can complete the collection of samples from multiple sites. However, it is difficult for the patient to keep his mouth open for a long time, and the patient is prone to discomfort, which causes inconvenience to the staff in collecting oral tissue samples and affects the results of sampling and testing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1, by Figures 1 to 8 It is given that the present invention comprises:

[0032] A lower support 1, a lower right angle frame 2 is fixed to the top of the lower support 1, a sampling rack 3 is fixed to the outer wall of one side of the lower right angle frame 2, an upper right angle frame 11 is fixed to the outer wall of one side of the sampling rack 3, and the lower right angle frame 2 and the upper right angle frame 11 are symmetrical structures about the center line of the sampling rack 3;

[0033] An oral expansion maintenance component is installed on the outer wall of the sampling frame 3. The oral expansion maintenance component includes a transmission box 10, a power transmission component inside the transmission box 10, a relative lifting component, a sliding support, a lower lip pressing plate 6 and an upper lip pressing plate 7. The transmission box 10 is installed on the outer wall of one side of the sampling frame 3. The staff uses the lower lip pressing plate 6 and the upper lip pressing plate 7 to expand the patient's oral cavity in the vertical direction, so that the patient's oral cavity is maintained in a suitable sampling state, which provides convenience for the staff's sampling operation;

[0034] The lower lip pressure plate 6 and the upper lip pressure plate 7 are installed at the two ends of the opposite lifting components. The power transmission component is used to drive the opposite lifting components to work. Two groups of sliding supports are provided, which are respectively installed on the outer wall of the sampling frame 3;

[0035] The lifting components toward each other are a lower screw module 8 and an upper screw module 9, which are installed on the outer wall of one side of the sampling frame 3. The two are symmetrical and have the same structure about the center line of the sampling frame 3. The upper screw module 9 includes two sets of vertical bearing seats 901 fixed on the outer wall of the sampling frame 3, and a ball screw 902 is rotatably installed between the two sets of vertical bearing seats 901. The top of the ball screw 902 is connected to the power transmission component, and a nut pair is installed at the thread on one side of the surface of the ball screw 902. The nut pair is fixedly connected through a sliding support and an upper lip pressure plate 7;

[0036] The sliding support is a linear guide rail 301 fixed on the outer wall of the sampling machine frame 3, and a sliding sleeve 302 is slidably installed on one end of the surface of the linear guide rail 301, a U-shaped plate 4 is fixed on the outer wall of the sliding sleeve 302, and a right-angle seat 5 is fixed on the outer wall of one side of the U-shaped plate 4, and the top end of the right-angle seat 5 is fixedly connected to the bottom end of the lower lip pressure plate 6;

[0037] During the movement of the lower lip pressing plate 6 and the upper lip pressing plate 7, the linear guide rail 301 and the sliding sleeve 302 improve the lifting stability of the lower lip pressing plate 6 and the upper lip pressing plate 7, so that the lower lip pressing plate 6 and the upper lip pressing plate 7 are stable and shake-free when expanding the oral cavity, thereby reducing the discomfort of the patient's oral cavity;

[0038] The power transmission component is an active bidirectional transmission component, two sets of transmission structures 1006 and a servo motor 13. The servo motor 13 is installed at the center of the surface of the transmission box 10. The output end of the servo motor 13 extends to the inside of the transmission box 10 and is interconnected with the active bidirectional transmission component. The active bidirectional transmission component is interconnected with the lower screw module 8 and the upper screw module 9 through the two sets of transmission structures 1006.

[0039] The staff turns on the servo motor 13 through the motor controller 201, so that the servo motor 13 makes the two sets of lower screw rod modules 8 and upper screw rod modules 9 work synchronously through the active bidirectional transmission components inside the transmission box 10;

[0040] Part of the power of the active bidirectional transmission assembly is transmitted to the ball screw 902 through the transmission structure 1006, and the ball screw 902 drives the upper lip pressing plate 7 upward through the nut pair, that is, the upper lip pressing plate 7 expands the patient's oral cavity upward;

[0041] A motor controller 201 is installed on the outer wall of one side of the lower right angle frame 2, and the output end of the motor controller 201 is electrically connected to the input end of the servo motor 13;

[0042] The transmission structure 1006 is a driving wheel installed at the end of the two sets of vertical shafts 1005, and a driven wheel installed at the top of the ball screw 902, and the driving wheel and the driven wheel are connected to each other through a crawler belt;

[0043] Similarly, the lower screw module 8 drives the U-shaped plate 4, the right-angle seat 5 and the lower lip pressing plate 6 downward, and the lower lip pressing plate 6 expands the patient's oral cavity downward until the patient's oral cavity is maintained in a state convenient for sampling;

[0044] The oral tissue sampling structure is arranged inside the sampling rack 3. The oral tissue sampling structure includes a hollow portion 303 arranged inside the sampling rack 3, a support plate 304 fixed inside the hollow portion 303, and a sampling member movably arranged inside the support plate 304. The sampling member includes a through hole 305 arranged inside the support plate 304, and an oral sampling swab 306 installed through the through hole 305. When the patient's oral cavity is fully expanded, the staff takes out the oral sampling swab 306, so that the oral sampling swab 306 penetrates through the through hole 305 and probes into the patient's oral cavity. The penetration depth is determined by the specific operation of the staff;

[0045] The patient constantly adjusts the position of the oral sampling swab 306 in the patient's oral cavity. Since the patient's oral cavity has been expanded and limited before, the staff can more accurately and finely sample the appropriate oral tissue sample. During the sampling process, the patient's oral cavity and the staff's hand are always separated by a distance, that is, the staff's hand will not touch the oral cavity, which can reduce the contact between the medical staff and the sample. The device can maintain the expansion of the patient's oral cavity during the sampling process, avoiding the patient's oral soreness caused by long-term mouth opening during the long sampling process, and at the same time brings convenience to the staff's oral tissue sampling and testing;

[0046] After the staff has finished sampling with the oral sampling swab 306, the staff releases the limit of the lower lip pressure plate 6 and the upper lip pressure plate 7 on the patient's oral cavity, and then the staff pulls the oral sampling swab 306 out of the through hole 305. At this time, the holding end of the oral sampling swab 306 needs to be pulled out of the through hole 305 to prevent the sampling end of the oral sampling swab 306 from contacting the support plate 304.

[0047] Embodiment 2, based on embodiment 1, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It is given that the active bidirectional transmission component includes a central shaft 1001 installed at the output end of the servo motor 13, a driving bevel gear 1002 is fixed to one side of the surface of the central shaft 1001, a vertical bearing seat 1004 is fixed to the inner wall of the transmission box 10, and both ends of the transmission box 10 are rotatably installed with a vertical shaft 1005 through the vertical bearing seat 1004, and a driven bevel gear 1003 is fixed to the bottom end of the vertical shaft 1005, and the driven bevel gear 1003 and the active bevel gear 1002 are meshed with each other;

[0048] When the two groups of lower lip pressing plates 6 and upper lip pressing plates 7 move toward each other, the servo motor 13 first drives the middle shaft 1001 and the active bevel gear 1002 to rotate, and the active bevel gear 1002 drives the two fitted driven bevel gears 1003 to rotate, and the driven bevel gear 1003 drives the vertical shaft 1005 and the transmission structure 1006 at the end of the vertical shaft 1005 to rotate, and the transmission structure 1006 drives the lower screw module 8 and the upper screw module 9 to work, and finally completes the patient's oral expansion operation. It has a simple structure and stable operation, and the side power transmission form provides convenience for the staff to operate the oral sampling swab 306;

[0049] Embodiment 3, based on embodiment 1, Figure 6 , Figure 7 and Figure 8 Provided, a first surfacing disinfection spray assembly 12 and a second surfacing disinfection spray assembly, the two have the same structure and are symmetrical about the center line of the sampling rack 3, the first surfacing disinfection spray assembly 12 is installed at the top of the lower right-angle frame 2, the second surfacing disinfection spray assembly is installed at the bottom of the upper right-angle frame 11, the first surfacing disinfection spray assembly 12 includes a supporting structure, a gear reciprocating transfer structure, a rotary drive and a spraying structure, the gear reciprocating transfer structure is installed on one side of the top of the supporting structure, the rotary drive is installed on one side of the bottom of the supporting structure, and the spraying structure is installed on the other side of the top of the supporting mechanism;

[0050] The supporting structure is a right-angle bracket 1201, a U-shaped frame 1202, a main shaft 1203 and a rectangular hollow seat 1204. The right-angle bracket 1201 is fixed on the outer wall of the lower right-angle frame 2. The U-shaped frame 1202 is provided with two groups. The two groups of U-shaped frames 1202 are fixed on both sides of the top of the right-angle bracket 1201. The main shaft 1203 is rotatably installed between the two groups of U-shaped frames 1202. The rectangular hollow seat 1204 is welded and fixed on the main shaft 1203.

[0051] The spraying structure is two groups of U-shaped nozzles 1205 and several groups of high-pressure nozzles 1206. The two groups of U-shaped nozzles 1205 are fixed on the top of the rectangular hollow seat 1204. The several groups of high-pressure nozzles 1206 are evenly arranged on the outer wall of the U-shaped nozzle 1205. The U-shaped nozzle 1205 is assembled from two groups of vertical pipes, two groups of three-way pipes and one group of horizontal pipes. The spraying structure is connected to the external disinfectant pumping end, that is, the disinfectant is introduced into the U-shaped nozzle 1205, and the part of the disinfectant is sprayed onto the lower lip pressure plate 6 and the upper lip pressure plate 7 through the high-pressure nozzle 1206;

[0052] The gear reciprocating transfer structure is a rack driven structure and a rack reciprocating transfer structure. The rack driven structure includes a driven gear roller 1207 fixed to one side of the main shaft 1203 surface, and a linear gear plate 1208 slidably installed at the bottom of the right-angle bracket 1201 below the driven gear roller 1207. The linear gear plate 1208 and the driven gear roller 1207 are meshed with each other. A hinged hollow column 1213 is fixed on the outer wall of one side of the linear gear plate 1208. The hinged hollow column 1213 and the rack reciprocating transfer structure are connected to each other.

[0053] The rack reciprocating transfer structure comprises a rotating shaft 1210, a first connecting rod 1211, a second connecting rod 1212 and a connecting block 1214. The rotating shaft 1210 is rotatably mounted on one side of the bottom of the right-angle bracket 1201. The first connecting rod 1211 is fixed to the top of the rotating shaft 1210. The second connecting rod 1212 is hinged to one side of the top of the first connecting rod 1211. The hinged hollow column 1213 is fixed to the top of the hinged hollow column 1213. The end of the second connecting rod 1212 away from the first connecting rod 1211 is hinged to the connecting block 1214.

[0054] The rotary driver is a second motor 1209, which is installed on one side of the bottom end of the right-angle bracket 1201. The output end of the second motor 1209 is fixedly connected to the bottom end of the rotating shaft 1210, and the input end of the second motor 1209 is electrically connected to the output end of the motor controller 201. The second motor 1209 enables the linear gear plate 1208 to work through the gear reciprocating transfer structure, that is, the second motor 1209 drives the rotating shaft 1210 and the first connecting rod 1211 to rotate, and the rotary motion of the first connecting rod 1211 is converted into the horizontal reciprocating motion of the hinged hollow column 1213 and the linear gear plate 1208 under the connection of the second connecting rod 1212 and the connecting block 1214;

[0055] During the reciprocating horizontal movement of the linear tooth plate 1208, the linear tooth plate 1208 can reciprocate and drive the driven tooth roller 1207 and the main shaft 1203 to rotate forward and reverse. Since the spraying structure is fixed on the main shaft 1203 through the rectangular hollow seat 1204, the U-shaped nozzle 1205 changes from linearly spraying disinfectant onto the lower lip pressure plate 6 to surface spraying disinfectant, so that the lower lip pressure plate 6 can be fully disinfected and cleaned.

[0056] When the embodiment of the present application is used, the staff first places the device on the installation plane, and then uses the lower lip pressure plate 6 and the upper lip pressure plate 7 to expand the patient's oral cavity in the vertical direction, so that the patient's oral cavity is maintained in a suitable sampling state, which provides convenience for the staff's sampling operation. During this process, the patient holds the lower lip pressure plate 6 and the upper lip pressure plate 7, and then the staff turns on the servo motor 13 through the motor controller 201, so that the servo motor 13 drives the two sets of lower wires through the active bidirectional transmission components inside the transmission box 10. The rod module 8 and the upper screw module 9 work synchronously. At this time, taking the upper screw module 9 as an example, part of the power transmission structure 1006 of the active two-way transmission component is transmitted to the ball screw 902, and the ball screw 902 drives the upper lip pressure plate 7 upward through the nut pair, that is, the upper lip pressure plate 7 expands the patient's oral cavity upward. Similarly, the lower screw module 8 drives the U-shaped plate 4, the right-angle seat 5 and the lower lip pressure plate 6 downward, and the lower lip pressure plate 6 expands the patient's oral cavity downward until the patient's oral cavity is maintained in a state convenient for sampling. During the movement of the lower lip pressure plate 6 and the upper lip pressure plate 7 During the process, the linear guide 301 and the sliding sleeve 302 improve the lifting stability of the lower lip pressure plate 6 and the upper lip pressure plate 7, so that the lower lip pressure plate 6 and the upper lip pressure plate 7 are stable and shaken when expanding the oral cavity, thereby reducing the discomfort of the patient's oral cavity. When the patient's oral cavity is fully expanded, the staff takes out the oral sampling swab 306, and allows the oral sampling swab 306 to penetrate into the patient's oral cavity from the through hole 305. The insertion depth is determined by the specific operation of the staff. During this process, the patient constantly adjusts the position of the oral sampling swab 306 in the patient's oral cavity. Since the patient's oral cavity has been expanded and limited before, the staff can sample the appropriate oral tissue sample more accurately and finely. During the sampling process, the patient's oral cavity and the staff's hand are always separated by a distance, that is, the staff's hand will not touch the oral cavity, which can reduce the contact between the medical staff and the sample. The device can maintain the expansion degree of the patient's oral cavity during sampling, avoiding the patient's oral cavity soreness caused by long-term mouth opening during long-term sampling, and at the same time brings convenience to the staff's oral tissue sampling and detection;

[0057] Subsequently, the staff connected the spraying structure to the external disinfectant pumping end, that is, the disinfectant was introduced into the U-shaped nozzle 1205, and the part of the disinfectant was sprayed onto the lower lip pressure plate 6 and the upper lip pressure plate 7 through the high-pressure nozzle 1206. During this process, the staff turned on the first surface disinfection spraying assembly 12 and the second motor 1209 in the second surface disinfection spraying assembly to work together, so that the second motor 1209 made the linear gear plate 1208 work through the gear reciprocating transfer structure, that is, the second motor 1209 drove the rotating shaft 1210 and the first connecting rod 1211 to rotate, and the first connecting rod 1211 was driven by the second motor 1209 to rotate. The rotary motion of the rod 1211 is converted into the horizontal reciprocating motion of the hinged hollow column 1213 and the linear tooth plate 1208 under the connection of the second connecting rod 1212 and the connecting block 1214. The reciprocating transmission structure of the rack enables the spraying structure to be transformed into a surface spraying disinfectant, so that the lower lip pressure plate 6 is fully disinfected and cleaned, avoiding the retention of oral fluid in the patient on the lower lip pressure plate 6 or the upper lip pressure plate 7.
