Description

Technical Field

[0001] This invention relates to the field of otolaryngology surgical instruments, and in particular to a multifunctional drug administration tray for tympanoplasty. Background Technology

[0002] In middle ear microsurgeries such as tympanoplasty, surgeons frequently use various medications and auxiliary materials, mainly including: 1) undiluted epinephrine solution (used to soak tiny cotton pads for local hemostasis); 2) epinephrine saline solution diluted in a specific ratio; 3) dexamethasone injection; and 4) erythromycin eye ointment or ointment. In addition, it is necessary to process the micro-tissue specimens obtained during the surgery.

[0003] The current standard practice in operating rooms is to use multiple independent 50mL medicine cups to hold different liquids and affix handwritten labels. This method has significant drawbacks: 1. Container mismatch: The volume of the 50mL medicine cup is much larger than the actual amount of medicine needed (usually only 1-2mL), resulting in a large area of ​​the medicine solution spreading out, easy evaporation, easy contamination, and visual inconvenience for accurate estimation.

[0004] 2. Identification and identification defects: Handwritten labels are prone to becoming blurred, falling off, or being misidentified during stressful surgical procedures, especially for clear liquids that look similar (such as adrenaline solution and its dilution, dexamethasone), posing a risk of misuse.

[0005] 3. Uncontrolled Management of High-Risk Medications and Supplies: Adrenaline solution is a high-risk medication, and the tiny cotton pads (approximately 2x10mm) soaked in it are strictly controlled items that must be counted during surgery. Currently, the cotton pads are randomly placed on damp gauze, making them easily lost and difficult to count, which does not meet infection control and safety verification requirements.

[0006] 4. Disorganized placement of items: Erythromycin ointment is often squeezed randomly onto gauze or instrument tables, making it difficult to manage the dosage and contamination status.

[0007] 5. Non-standardized procedures: The concentration of adrenaline diluent depends on the surgeon's personal habits, and there is a lack of immediate and intuitive standardized guidance within the hospital. Summary of the Invention

[0008] In view of this, the present invention proposes a multifunctional drug management tray for tympanoplasty, which can realize the zonal management of drugs and items, optimize surgical efficiency and improve surgical safety.

[0009] The technical solution of this invention is implemented as follows: A multifunctional medication management tray for tympanoplasty includes an open tray and a partition. The partition is disposed inside the open tray and divides the interior of the open tray into a first chamber, a second chamber, a third chamber, a fourth chamber, a fifth chamber, and a sixth chamber. The first chamber is used to hold epinephrine concentrate, and its inner bottom surface is provided with several cotton pad placement positions, with a digital prompt mechanism below each cotton pad placement position. The second chamber is used to hold epinephrine dilution, the third chamber is used to store tissue samples, the fourth chamber is used to hold hormonal drugs, and the fifth chamber is used to hold ointment drugs.

[0010] Preferably, the inner walls of the first chamber, second chamber, third chamber, fourth chamber, and fifth chamber are provided with prompts.

The main control unit and the digital prompting mechanism are disposed inside the base. The digital prompting mechanism is disposed below the first chamber and is used for digital dynamic display below the light-transmitting plate. The main control unit is electrically connected to the photodetector and the digital prompting mechanism respectively.

[0012] Preferably, the digital prompting mechanism includes a rotary motor, a rotating shaft, a prism, and a synchronization mechanism. The rotary motor is disposed on the inner side wall of the base, and its output shaft is connected to one end of the rotating shaft. The prism is located below the cotton pad placement position, and each side of the prism is provided with a digital area. A through hole is provided through the end face of the prism. The rotating shaft passes through all the through holes of the prism. The synchronization mechanism is disposed on the rotating shaft to realize the synchronous rotation of the prism and the rotating shaft. The light-transmitting plate is located above the rotation path of the digital area. The main control unit is electrically connected to the rotary motor and the synchronization mechanism respectively.

[0013] Preferably, the digital display mechanism further includes a bearing housing, which is disposed on the bottom surface of the open tray, and the end of the rotating shaft away from the rotating motor is connected to the bearing housing.

[0014] Preferably, the synchronization mechanism includes an electric push rod and an abutment plate.

[0022] To better understand the technical content of this invention, a specific embodiment is provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0023] See Figures 1 to 4 This invention provides a multifunctional drug management tray for tympanoplasty, comprising an open tray 1 and a partition 2. The partition 2 is disposed inside the open tray 1 and divides the interior of the open tray 1 into a first chamber 3, a second chamber 4, a third chamber 5, a fourth chamber 6, a fifth chamber 7, and a sixth chamber 8. The first chamber 3 is used to hold adrenaline solution, and its inner bottom surface is provided with several cotton pad placement positions 9, with a digital prompt mechanism below each cotton pad placement position 9. The second chamber 4 is used to hold adrenaline dilution, the third chamber 5 is used to store tissue samples, the fourth chamber 6 is used to hold hormonal drugs, and the fifth chamber 7 is used to hold ointment drugs.

[0024] This invention discloses a multifunctional medication management tray for tympanoplasty. Based on the frequent use of various medications and auxiliary materials in middle ear microsurgeries such as tympanoplasty, a partition 2 is installed inside the open tray 1, dividing the interior of the open tray 1 into six chambers. Each chamber is used to store different medications and items. The first chamber 3 is used to hold epinephrine concentrate and serves as a platform for soaking and counting cotton pads. The second chamber 4 is used to hold epinephrine dilution solution, allowing nurses to mix the epinephrine concentrate with saline solution according to a preset ratio. The third chamber 5 is used for temporary storage of small tissue specimens obtained during surgery, such as the incus and granulation tissue. To avoid confusion or disposal of medications in other chambers, the fourth chamber 6 is used to hold hormone medications such as dexamethasone. The fifth chamber 7 is used to hold erythromycin ointment, which can be dispensed in precise quantities into the fifth chamber 7. The size of the fifth chamber 7 is just right to accommodate the reasonable amount used in a single surgery, standardizing the use of ointment, reducing contamination, and facilitating use and observation of the remaining amount. The sixth chamber 8 serves as an extension or spare area, which can be used to place saline cotton balls or other small items as needed for specific surgeries. Through the setting of multiple chambers, all items can be managed in a fixed location, eliminating the need for nurses and doctors to search for them and greatly improving the speed of retrieval. At the same time, the open tray 1 can consolidate cluttered items and keep the operating table clean and orderly.

[0025] Several cotton pad placement positions 9 are set up in the first chamber 3. After the nurse soaks the cotton pads in adrenaline solution, they can be placed in the cotton pad placement positions 9. After the doctor picks up the cotton pads with tweezers, the number indicator below the cotton pad will display the number in the order of 1-10, indicating the number of cotton pads picked up by the doctor. The picked cotton pads can be transferred to another area for recycling. After the operation, the number on the cotton pad placement position 9 can be used to quickly determine the number of cotton pads used and compare it with the number of cotton pads recycled, realizing a closed-loop counting of cotton pads. This solves the problem of small cotton pads being difficult to count and easy to lose, reduces the risk of items being left behind, and improves the safety of the operation.

[0026] Preferably, the inner walls of the first chamber 3, the second chamber 4, the third chamber 5, the fourth chamber 6, and the fifth chamber 7 are provided with prompts.

[0027] The side wall of the first chamber 3 can be laser-engraved with high-alert colors such as red or yellow, and engraved with the words "Adrenaline Solution" and "High Risk" to achieve real-time visual warning. The inner wall of the second chamber 4 can be engraved with standardized dilution formulas, such as "Adrenaline Solution: 10 drops + physiological saline: 10mL", which can remind medical staff to dilute according to the preset formula, promote standardized medical treatment, and reduce fluctuations in surgical effects caused by differences in concentration. The side wall or bottom of the third chamber 5 can be engraved with the words "Specimen" and supplemented with graphic symbols to distinguish it from the drug solution area and prevent possible confusion or disposal. The side wall of the fourth chamber 6 can be engraved with the words "Dexamethasone" to indicate that the chamber is used to hold dexamethasone.

[0028] Preferably, the device also includes a base 10, a photodetector 11, and a main control unit 12. The top surface of the base 10 is open, and the open tray 1 is connected above the base 10. A light-transmitting plate 13 is provided in the middle of the cotton pad placement position 9. The photodetector 11 is disposed on the cotton pad placement position 9 and located on both sides of the light-transmitting plate 13. The main control unit 12 and the digital prompting mechanism are disposed inside the base 10. The digital prompting mechanism is disposed below the first chamber 3 and is used for digital dynamic display below the light-transmitting plate 13. The main control unit 12 is electrically connected to the photodetector 11 and the digital prompting mechanism respectively.

[0029] A base 10 is provided at the bottom of the open image, so that the digital prompting mechanism can be integrated inside the base 10. The photodetector 11 on the cotton pad placement position 9 can detect the placement and removal of the cotton pad. When the cotton pad is placed, it will block the photodetector 11 and the light-transmitting plate 13. When the doctor removes the cotton pad, the photodetector 11 detects that the cotton pad has been removed. The main control unit 12 receives the data sent by the photodetector 11, determines which cotton pad it is, and then displays a number below the light-transmitting plate 13 of the corresponding cotton pad placement position 9 through the digital prompting mechanism to indicate the number of cotton pads used.

[0030] Preferably, the digital prompting mechanism includes a rotary motor 14, a rotating shaft 15, a prism 16, and a synchronization mechanism. The rotary motor 14 is disposed on the inner side wall of the base 10, and its output shaft is connected to one end of the rotating shaft 15. The prism 16 is located below the cotton pad placement position 9, and each side of the prism 16 is provided with a digital area 17. The end face of the prism 16 is provided with a through hole 18. The rotating shaft 15 passes through all the through holes 18 of the prism 16. The synchronization mechanism is disposed on the rotating shaft 15 to realize the synchronous rotation of the prism 16 and the rotating shaft 15. The light-transmitting plate 13 is located above the rotation path of the digital area 17. The main control unit 12 is electrically connected to the rotary motor 14 and the synchronization mechanism respectively.

[0031] Below each cotton pad placement position 9 is a corresponding prism 16. The through holes 18 of the prisms 16 in the same row are aligned. The rotating shaft 15 can pass through the through holes 18 of the prisms 16 in the same row. The cotton pad placement positions 9 of the present invention are preferably set to two rows with a total of 10, that is, 5 in one row. Therefore, the rotary motor 14 and the rotating shaft 15 are set to two sets to drive the rotation of the two rows of prisms 16 separately. A number area 17 is set on the side of the prism 16. When the prism 16 rotates, the number area 17 at different positions can rotate to the bottom of the light-transmitting plate 13 for display. The prism 16 is a decaprism. The number areas 17 are marked with 1-10 respectively, with each side corresponding to a number to show the number of cotton pads taken away.

[0032] After the cotton pad is removed, the main control unit 12 drives the rotary motor 14 to rotate the rotating shaft 15. The synchronization mechanism can rotate the prism 16 below the cotton pad placement position 9 after the cotton pad is removed synchronously with the rotating shaft 15, so that the corresponding digital area 17 rotates to the underside of the light-transmitting plate 13. For example, when the first cotton pad is removed, the display under its light-transmitting plate 13 is 1, when the second cotton pad is removed, the display under its light-transmitting plate 13 is 2, and so on. The number of cotton pads removed can be quickly determined after the operation.

[0033] In addition, since doctors do not pick up cotton pads in a fixed order, the numbers displayed on the translucent plate 13 will not be displayed in order. After the surgery, the maximum number displayed on the translucent plate 13 of the cotton pad placement position 9 where no cotton pads were placed is the number of cotton pads used.

[0034] Preferably, the digital display mechanism further includes a bearing seat 19, which is disposed on the bottom surface of the open tray 1, and the end of the rotating shaft 15 away from the rotating motor 14 is connected to the bearing seat 19.

[0035] When the shaft 15 rotates, its end can rotate under the support of the bearing seat 19, ensuring the stability of the rotation of the prism 16.

[0036] Preferably, the synchronization mechanism includes an electric push rod 20 and an abutment plate 21. The electric push rod 20 is symmetrically arranged on the outer wall of the rotating shaft 15, and its output shaft is connected to the concave surface of the abutment plate 21. The convex surface of the abutment plate 21 faces the inner wall of the through hole 18. The main control unit 12 is electrically connected to the electric push rod 20.

[0037] The electric actuator 20 can drive the abutment plate 21 to move. The abutment plate 21 has an arc-shaped structure with its convex surface facing the through hole 18. When the convex surface of the abutment plate 21 abuts against the inner wall of the through hole 18, friction is generated by the pressure of the abutment, which can realize the synchronization of the prism 16 and the rotating shaft 15. When the rotating shaft 15 rotates, the electric actuator 20 and the abutment plate 21 drive the prism 16 to rotate synchronously.

[0038] Preferably, the synchronization mechanism further includes an electric slide 22, which is disposed on the outer wall of the rotating shaft 15, and the electric push rod 20 is disposed on the mover of the electric slide 22. The main control unit 12 is electrically connected to the electric slide 22.

[0039] The rotating shaft 15 passes through multiple prisms 16. In order to achieve synchronous control of multiple prisms 16, an electric slide 22 is provided on the outer wall of the rotating shaft 15. The electric slide 22 can drive the electric push rod 20 to move, so that the electric push rod 20 and the abutment plate 21 can move into the through hole 18 of different prisms 16, thereby enabling different prisms 16 to be synchronously connected with the rotating shaft 15.

[0040] Preferably, the digital prompting mechanism further includes a magnetic block 23 and a metal block 24. The magnetic block 23 is disposed on the bottom surface of the open tray 1 and located on both sides of the cotton pad placement position 9. The metal block 24 is disposed on the side wall of the prism 16 and located on both sides of the digital area 17. The magnetic block 23 is located above the moving path of the metal block 24.

[0041] When the prism 16 is not synchronized with the rotating shaft 15, the abutment plate 21 will move away from the inner wall of the through hole 18, and the magnetic block 23 can magnetically attract the metal block 24, so that the prism 16 is suspended above the base 10, avoiding affecting the rotation of the rotating shaft 15. At the same time, through the magnetic attraction and positioning effect of the magnetic block 23 and the metal block 24, it can be ensured that the digital area 17 can be accurately located below the light-transmitting plate 13, so that medical staff can accurately identify the number of cotton pads used.

[0042] Preferably, the digital prompting mechanism further includes a Hall sensor 25, which is disposed inside the prism 16 and located inside the metal block 24, and the main control unit 12 is electrically connected to the Hall sensor 25.

[0043] Hall sensors 25 are also provided on the inner sidewall of each metal block 24. When the metal block 24 is magnetically attracted by the magnetic block 23, the Hall sensor 25 can collect the corresponding magnetic field data and transmit it to the main control unit 12. The main control unit 12 can determine the specific digital area 17 facing the light-transmitting plate 13 based on the received data, so as to accurately locate the digital area 17.

[0044] Preferably, it also includes an anti-slip pad 26, which is disposed on the bottom surface of the base 10.

[0045] The anti-slip pad 26 increases the friction with the table surface and prevents the base 10 from shifting when the rotary motor 14 rotates.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
