Description

Technical Field

[0001] This invention relates to the field of transport device technology, and specifically to a surgical instrument pretreatment and transport device and method. Background Technology

[0002] Reusable surgical instruments (such as metal scalpel handles, scissors, forceps, etc.) are core tools in daily hospital diagnosis and treatment. In the current hospital operation process, surgical instruments are usually simply wiped or preliminarily cleaned by operating room nurses after the operation, and then placed directly into sealed transport boxes and transported to the sterilization supply center through a dedicated logistics channel for subsequent cleaning, disinfection and sterilization.

[0003] However, in practice, due to the tight schedule of surgical procedures or insufficient awareness of pre-treatment among staff, blood, body fluids, and tissue residues adhering to the instrument surfaces often cannot be cleaned in a timely manner. During the transfer from the operating room to the sterilization supply center, these organic contaminants quickly dry and solidify on the instrument surfaces over time and with temperature changes. These dried and solidified contaminants are difficult to remove through routine rinsing in the sterilization supply center. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a surgical instrument pretreatment and transfer device and method to solve the problem in the prior art that, during the transfer from the operating room to the sterilization supply center, these organic contaminants will quickly dry and solidify on the surface of the instruments over time and with temperature changes, and the dried and solidified contaminants are difficult to remove by conventional rinsing in the sterilization supply center.

[0005] This invention is achieved through the following technical solution: A surgical instrument pretreatment and transport device includes a box, a first rotating shaft rotatably connected to the bottom of the box, and wheels fixedly connected to both ends of the first rotating shaft. A partition is vertically arranged inside the box, dividing the interior of the box into a first cavity and a second cavity for holding cleaning fluid. A gear pump is fixedly connected to the first cavity, and a linkage component is installed between the gear pump and the first rotating shaft. The linkage component can drive the gear pump to run during the rotation of the first rotating shaft. The second cavity is equipped with a collection box. The side wall of the collection box is provided with a channel for the flow of cleaning fluid and multiple spray holes. The multiple spray holes are distributed at intervals along the length of the channel. The input end of the gear pump is connected to a first pipe. The end of the first pipe away from the gear pump is connected to the second cavity. The output end of the gear pump is connected to a second pipe. The end of the second pipe away from the gear pump is connected to the channel.

[0006] Furthermore, the middle part of the first rotating shaft is located in the first cavity, and a one-way bearing is fixedly connected to the first rotating shaft.

The rotating shaft of the gear pump passes through its housing. A second sprocket is fixedly connected to the rotating shaft of the gear pump. A transmission assembly is installed between the first sprocket and the second sprocket. When the traveling wheel and the first rotating shaft rotate forward, the one-way bearing is in a locked state, driving the first sprocket to rotate, and can drive the second sprocket and the rotating shaft of the gear pump to rotate under the action of the transmission assembly. When the traveling wheel and the first shaft stop or rotate backward, the one-way bearing is in an overrunning state, and the traveling wheel and the first shaft rotate in reverse without driving the gear pump and transmission assembly in the opposite direction.

[0007] Furthermore, the transmission assembly includes a second rotating shaft rotatably connected to the housing, the second rotating shaft being located within the first cavity, and a third sprocket and a fourth sprocket being fixedly connected to both ends of the second rotating shaft, respectively. A first chain is tensioned and engaged between the third sprocket and the first sprocket, and a second chain is tensioned and engaged between the fourth sprocket and the second sprocket.

[0008] Furthermore, a cam is fixedly connected to the second rotating shaft, a slide rod is slidably connected to the partition plate, a limit plate is fixedly connected to one end of the slide rod near the cam, a spring is provided between the limit plate and the partition plate, the spring is sleeved on the slide rod, and the two ends of the spring abut against the side walls of the limit plate and the partition plate respectively. A lock seat is fixedly connected to one end of the slide rod near the collection box, and a locking tongue adapted to the lock seat is fixedly connected to the collection box, the locking tongue being able to engage with the lock seat.

[0009] Furthermore, a cover plate is fixedly connected to the top of the first cavity, and a cover body is fastened to the top of the second cavity. A locking block is fixedly connected to the cover body. A slot adapted to the locking block is provided on the cover plate, and the locking block passes through the slot. A sliding groove is provided on the cover plate, and a push rod is slidably connected in the sliding groove. A handle is fixedly connected to the upper end of the push rod, and the handle can cover the sliding groove. A locking rod is fixedly connected to the lower end of the push rod, and the locking rod extends along the length direction of the sliding rod. A lock hole adapted to the locking rod is provided on the locking block. The top of the limiting plate is at the same horizontal height as the locking rod. When the limiting plate moves towards the partition, it can push the locking rod through the lock hole.

[0010] Furthermore, a flow guide box is fixedly connected inside the second cavity. The top opening of the flow guide box gradually narrows from top to bottom, and a through hole is provided at the bottom of the flow guide box. The end of the first tube away from the gear pump is connected to the through hole.

[0011] Furthermore, the bottom of the flow guide box is provided with a three-way connector and a third pipe. The three-way connector is connected to the first pipe, the third pipe and the through hole respectively. The third pipe extends vertically downward and penetrates the side wall of the box. The lower end of the third pipe is detachably fixedly connected with a plug.

[0012] Furthermore, a mounting bracket is fixedly connected to the partition plate, a first gear is rotatably connected to the mounting bracket and a motor is fixedly connected to it, a centrifugal assembly is installed between the output shaft of the motor and the first gear, the centrifugal assembly can drive the first gear to rotate synchronously when the output shaft speed of the motor exceeds a set value, and a second gear that meshes with the first gear is fixedly connected to the shaft of the gear pump.

[0013] Furthermore, the centrifugal assembly includes a centrifugal sleeve fixedly connected to the output shaft of the motor. The centrifugal sleeve has a guide groove that extends radially along the output shaft of the motor. A tension spring is disposed in the guide groove and a centrifugal block is slidably connected thereto. The two ends of the tension spring are fixedly connected to the centrifugal block and the side wall of the guide groove, respectively. When the tension spring is in its naturally extended state, the centrifugal block is entirely located within the guide groove. A circular groove is formed at the center of the first gear. The groove is fitted onto the centrifugal sleeve and multiple locking blocks are fixedly connected within the groove. The multiple locking blocks are distributed circumferentially around the groove. When the output shaft speed of the motor exceeds a set value, the centrifugal block overcomes the tension of the tension spring, protrudes out of the guide groove, and abuts against the side wall of the corresponding locking block.

[0014] A method for pre-processing and transporting surgical instruments, comprising a surgical instrument pre-processing and transporting device. S1. Move the handle away from the second cavity to disengage the locking rod from the lock hole, open the cover, and inject sufficient cleaning fluid into the second cavity; S2. Place the reusable surgical instruments into the collection box in the second cavity, fasten the cover to the top of the second cavity, and pass the locking block through the slot so that the locking rod and the locking hole are on the same straight line. S3. The operator pushes the box from the operating room to the sterilization supply center. During the forward movement of the box by the walking wheels, the first rotating shaft, the one-way bearing and the first sprocket rotate simultaneously. The first sprocket drives the third sprocket, the second rotating shaft, the cam and the fourth sprocket to rotate in the same direction through the first chain. The fourth sprocket drives the second sprocket and the rotating shaft of the gear pump to rotate in the same direction through the second chain. S4. During the forward movement of the box driven by the walking wheels, the gear pump runs continuously. The input end of the gear pump draws cleaning fluid from the bottom of the second cavity through the first pipe. After being pressurized by the gear pump, the cleaning fluid is transported to the channel on the side wall of the collection box through the second pipe and sprayed out from the multiple spray holes. The sprayed cleaning fluid directly washes the surface of the surgical instruments in the collection box. S5. During the rotation of the cam, when the protruding end of the cam abuts against the side wall of the limiting plate, the cam pushes the limiting plate to move towards the partition, pushes the locking rod to move towards the partition, the locking rod passes through the lock hole, and the spring is compressed. The sliding rod drives the collection box to move away from the first cavity through the locking tongue and the locking seat. When the protruding end of the cam does not abut against the side wall of the limiting plate, the limiting plate and the slide rod are reset under the elastic force of the spring, and the slide rod drives the collection box to move closer to the first cavity through the locking tongue and the locking seat; The reciprocating movement of the collection box causes the reusable surgical instruments inside to shake. S6. When the box arrives at the disinfection supply center, the operator stops pushing it, the wheels stop turning, and the gear pump stops working. S7. Move the handle away from the second cavity to disengage the locking rod from the lock hole, open the cover, take out the reusable surgical instrument that has been preliminarily rinsed, and transfer it to the sterilization supply center for subsequent deep cleaning and sterilization processes.

[0015] The beneficial effects of this invention are as follows: This surgical instrument pretreatment and transport device and method utilizes the transport time from the operating room to the sterilization supply center to pressurize the cleaning fluid in the second chamber through a gear pump and spray it out from the nozzle to rinse the surgical instruments in a timely manner, effectively reducing the probability of organic contaminants such as blood and body fluids drying and solidifying on the instrument surface.

[0024] Please see Figure 1-10 The present invention provides a technical solution: a surgical instrument pretreatment and transport device, including a box 1, a first rotating shaft 2 rotatably connected to the bottom of the box 1, and two wheels 3 fixedly connected to both ends of the first rotating shaft 2. A partition 4 is vertically arranged inside the box 1, which divides the inside of the box 1 into a first cavity 5 and a second cavity 6 for holding cleaning fluid. A gear pump 7 is fixedly connected inside the first cavity 5. A linkage component 8 is installed between the gear pump 7 and the first rotating shaft 2. The linkage component 8 can drive the gear pump 7 to run during the rotation of the first rotating shaft 2. The second cavity 6 is equipped with a collection box 9. The side wall of the collection box 9 is provided with a channel 10 for the flow of cleaning fluid and a plurality of spray holes 11. The plurality of spray holes 11 are distributed at intervals along the length of the channel 10. The input end of the gear pump 7 is connected to a first tube 12. The end of the first tube 12 away from the gear pump 7 is connected to the second cavity 6. The output end of the gear pump 7 is connected to a second tube 13. The end of the second tube 13 away from the gear pump 7 is connected to the channel 10.

[0025] The middle part of the first rotating shaft 2 is located in the first cavity 5. A one-way bearing 14 is fixedly connected to the first rotating shaft 2. The linkage component 8 includes a first sprocket 15 sleeved on the one-way bearing 14. The first sprocket 15 is fixedly connected to the outer ring of the one-way bearing 14. The rotating shaft of the gear pump 7 passes through its housing. A second sprocket 16 is fixedly connected to the rotating shaft of the gear pump 7. A transmission component 17 is installed between the first sprocket 15 and the second sprocket 16. When the traveling wheel 3 and the first rotating shaft 2 rotate forward, the one-way bearing 14 is in a locked state, driving the first sprocket 15 to rotate, and can drive the second sprocket 16 and the rotating shaft of the gear pump 7 to rotate under the action of the transmission component 17. When the traveling wheel 3 and the first rotating shaft 2 stop or rotate backward, the one-way bearing 14 is in an overrunning state, and the traveling wheel 3 and the first rotating shaft 2 rotate in opposite directions without driving the gear pump 7 and the transmission assembly 17 in the opposite direction.

[0026] The transmission assembly 17 includes a second rotating shaft 18 rotatably connected to the housing 1. The second rotating shaft 18 is located in the first cavity 5. A third sprocket 19 and a fourth sprocket 20 are fixedly connected to both ends of the second rotating shaft 18, respectively. A first chain 21 is tensioned and engaged between the third sprocket 19 and the first sprocket 15. A second chain 22 is tensioned and engaged between the fourth sprocket 20 and the second sprocket 16.

[0027] In this design: a first rotating shaft 2 is rotatably connected to the bottom of the housing 1, with two fixed wheels 3 at both ends of the first rotating shaft 2. A gear pump 7 is fixedly connected inside the first cavity 5, and a linkage assembly 8 is installed between the gear pump 7 and the first rotating shaft 2. When the operator pushes the housing 1 forward, the wheels 3 rotate forward, causing the first rotating shaft 2 to rotate synchronously. During the rotation of the first rotating shaft 2, the linkage assembly 8 drives the gear pump 7, converting the mechanical energy of the wheels 3 into the power of the gear pump 7.

[0028] A collection box 9 is installed in the second cavity 6. The side wall of the collection box 9 has a channel 10 for the flow of cleaning fluid and multiple nozzles 11, which are spaced apart along the length of the channel 10. A partition 4 divides the interior of the box 1 into a first cavity 5 and a second cavity 6 for holding the cleaning fluid. The input end of a gear pump 7 is connected to a first tube 12, and the end of the first tube 12 away from the gear pump 7 is connected to the second cavity 6. The output end of the gear pump 7 is connected to a second tube 13, and the end of the second tube 13 away from the gear pump 7 is connected to the channel 10. The gear pump 7 pressurizes the cleaning fluid in the second cavity 6 and sprays it out through the nozzles 11 to promptly rinse the surgical instruments, effectively reducing the probability of organic contaminants such as blood and body fluids drying and solidifying on the instrument surface.

[0029] A one-way bearing 14 is fixedly connected to the first rotating shaft 2. A first sprocket 15 is sleeved on the one-way bearing 14. The first sprocket 15 is fixedly connected to the outer ring of the one-way bearing 14. The rotating shaft of the gear pump 7 passes through its housing. A second sprocket 16 is fixedly connected to the rotating shaft of the gear pump 7. A second rotating shaft 18 is rotatably connected to the housing 1. A third sprocket 19 and a fourth sprocket 20 are fixedly connected to the two ends of the second rotating shaft 18, respectively. The third sprocket 19 is tensioned and meshes with the first sprocket 15, and the fourth sprocket 20 is tensioned and meshes with the second sprocket 16, and the second chain 22 is meshed with the second sprocket 16.

[0030] When the traveling wheel 3 and the first rotating shaft 2 rotate forward, the one-way bearing 14 is locked, which drives the first sprocket 15 to rotate. The first sprocket 15 drives the third sprocket 19, the second rotating shaft 18, the cam 23 and the fourth sprocket 20 to rotate in the same direction through the first chain 21. The fourth sprocket 20 drives the second sprocket 16 and the rotating shaft of the gear pump 7 to rotate in the same direction through the second chain 22, which drives the gear pump 7 to run.

[0031] When the traveling wheel 3 and the first shaft 2 stop or rotate backward, the one-way bearing 14 is in an overrunning state, and the traveling wheel 3 and the first shaft 2 rotate in opposite directions without driving the gear pump 7 in the opposite direction, thus reducing the probability of damage to the gear pump 7.

[0032] In use, first open the cover 30 and inject sufficient cleaning solution into the second cavity 6; then place the reusable surgical instruments into the collection box 9 in the second cavity 6; then the operator pushes the box 1 from the operating room to the sterilization supply center. As the walking wheels 3 move the box 1 forward, they drive the first rotating shaft 2, the one-way bearing 14, and the first sprocket 15 to rotate simultaneously. The first sprocket 15 drives the third sprocket 19, the second rotating shaft 18, and the fourth sprocket 20 to rotate in the same direction via the first chain 21. The fourth sprocket 20 drives the second sprocket 16 and the shaft of the gear pump 7 to rotate in the same direction via the second chain 22. The gear pump 7 continuously operates. Okay, the gear pump 7 draws cleaning fluid from the bottom of the second cavity 6 through the first pipe 12. After being pressurized by the gear pump 7, the cleaning fluid is transported through the second pipe 13 to the channel 10 on the side wall of the collection box 9 and sprayed out from multiple nozzles 11. The sprayed cleaning fluid directly washes the surface of the surgical instruments in the collection box 9. When the box 1 reaches the sterilization supply center, the operator stops pushing, the wheels 3 stop rotating, and the gear pump 7 stops working. Finally, the cover 30 is opened, the reusable surgical instruments that have been initially rinsed are taken out, and they are transferred to the sterilization supply center for subsequent deep cleaning and sterilization processes.

[0033] Compared to existing technologies, by utilizing the transfer time from the operating room to the sterilization supply center, the cleaning fluid in the second chamber 6 is pressurized by the gear pump 7 and sprayed out from the nozzle 11 to rinse the surgical instruments in a timely manner, effectively reducing the probability of organic contaminants such as blood and body fluids drying and solidifying on the instrument surface.

A locking tongue 28 adapted to the lock seat 27 is fixedly connected to the collection box 9, and the locking tongue 28 can be engaged with the lock seat 27.

[0036] During the rotation of cam 23, when the protruding end of cam 23 abuts against the side wall of limiting plate 25, cam 23 pushes limiting plate 25 to move towards partition 4, spring 26 is compressed, and slide rod 24 drives collection box 9 to move away from first cavity 5 through locking tongue 28 and locking seat 27; when the protruding end of cam 23 does not abut against the side wall of limiting plate 25, limiting plate 25 and slide rod 24 are reset under the elastic force of spring 26, and slide rod 24 drives collection box 9 to move closer to first cavity 5 through locking tongue 28 and locking seat 27; during the reciprocating movement of collection box 9, the reusable surgical instruments inside shake; this allows the cleaning fluid sprayed from nozzle 11 to be more evenly and thoroughly rinsed onto all surfaces of the instruments, especially hard-to-clean dead corners such as intersections and depressions, significantly improving the pretreatment effect.

The locking rod 36 passes through the locking hole 37, and automatically locks the cover 30 during the transfer and rinsing process, reducing the probability of the cover 30 being accidentally opened, causing cleaning fluid to splash or instruments to fall, resulting in environmental pollution or personal injury.

When the output shaft speed of the motor 46 exceeds a set value, the centrifugal block 52 overcomes the tension of the tension spring 51, protrudes out of the guide groove 50, and abuts against the side wall of the corresponding locking block 54.

[0044] In this design: the power is generated by the driving wheels 3, and the power is transmitted through the transmission assembly 17, the first sprocket 15, and the second sprocket 16 to drive the gear pump 7. At this time, the motor 46 is not working, the centrifugal blocks 52 are all located in the guide groove 50, the output shaft of the motor 46 will not generate resistance to the rotation of the gear pump 7, and the probability of damage to the motor 46 is reduced.

[0045] When the chamber 1 reaches its destination (or stops en route), if a longer rinsing of the surgical instruments is required, the power supply (or battery) can be connected to start the motor 46. The output shaft speed of the motor 46 gradually increases from low to high. When the speed exceeds the set value, the centrifugal force generated by the centrifugal block 52 overcomes the tension of the tension spring 51 and is thrown outward, protruding out of the guide groove 50. The protruding centrifugal block 52 will abut against the side wall of the locking block 54 in the groove 53 of the first gear 45, thereby pushing the first gear 45 to rotate together with the output shaft of the motor 46, driving the second gear 48 that meshes with it, thereby driving the gear pump 7 to work and realize electric rinsing.

[0046] A method for pre-processing and transporting surgical instruments, comprising a surgical instrument pre-processing and transporting device. S1. Move the handle 35 away from the second cavity 6 to disengage the locking rod 36 from the lock hole 37, and open the cover 30 to inject sufficient cleaning fluid into the second cavity 6. S2. Place the reusable surgical instruments into the collection box 9 in the second cavity 6, fasten the cover 30 to the top of the second cavity 6, and pass the locking block 31 through the slot 32 so that the locking rod 36 and the lock hole 37 are on the same straight line. S3. The operator pushes the box 1 from the operating room to the sterilization supply center. During the forward movement of the box 1 driven by the walking wheels 3, the first rotating shaft 2, the one-way bearing 14 and the first sprocket 15 rotate simultaneously. The first sprocket 15 drives the third sprocket 19, the second rotating shaft 18, the cam 23 and the fourth sprocket 20 to rotate in the same direction through the first chain 21. The fourth sprocket 20 drives the second sprocket 16 and the rotating shaft of the gear pump 7 to rotate in the same direction through the second chain 22. S4. During the forward movement of the box 1 driven by the walking wheel 3, the gear pump 7 runs continuously. The input end of the gear pump 7 draws cleaning fluid from the bottom of the second cavity 6 through the first pipe 12. After being pressurized by the gear pump 7, the cleaning fluid is transported to the channel 10 on the side wall of the collection box 9 through the second pipe 13 and sprayed out from the multiple spray holes 11. The sprayed cleaning fluid directly washes the surface of the surgical instruments in the collection box 9. S5. During the rotation of the cam 23, when the protruding end of the cam 23 abuts against the side wall of the limiting plate 25, the cam 23 pushes the limiting plate 25 to move towards the partition 4, and pushes the locking rod 36 to move towards the partition 4. At the same time, the locking rod 36 passes through the lock hole 37, and the spring 26 is compressed. The slide rod 24 drives the collection box 9 to move away from the first cavity 5 through the locking tongue 28 and the locking seat 27. When the protruding end of the cam 23 does not abut against the side wall of the limiting plate 25, the limiting plate 25 and the slide rod 24 are reset under the elastic force of the spring 26, and the slide rod 24 drives the collection box 9 to move closer to the first cavity 5 through the locking tongue 28 and the locking seat 27. The reciprocating movement of the collection box 9 causes the reusable surgical instruments inside to shake. S6. When the box 1 arrives at the disinfection supply center, the operator stops pushing it, the walking wheels 3 stop rotating, and the gear pump 7 stops working. S7. Move the handle 35 away from the second cavity 6 to disengage the locking rod 36 from the lock hole 37, open the cover 30, take out the reusable surgical instrument that has been preliminarily rinsed, and transfer it to the sterilization supply center for subsequent deep cleaning and sterilization processes.

[0047] Technical Benefits: In traditional processes, the transfer time from the operating room to the sterilization supply center is a gap. This surgical instrument pretreatment and transfer method transforms this ineffective time into effective processing time. By utilizing this unavoidable logistics time, the cleaning process is initiated in advance, essentially bringing forward some of the work in the sterilization supply center, achieving parallel processing throughout the entire process. Surgical instruments remain moist throughout the transfer, and continuous rinsing reduces the probability of contaminants solidifying and denaturing, keeping them in a loose state that is easily dissolved and rinsed away.

[0048] Continuous spraying and reciprocating shaking create a combined cleaning effect of dynamic soaking and physical rinsing. This effect effectively loosens contaminants in hard-to-reach areas of surgical instruments, laying the foundation for subsequent deep cleaning processes such as ultrasonic cleaning and enzyme washing in the sterilization supply center, and improving the final cleaning pass rate.

[0049] The automatic safety interlock mechanism eliminates the need for manual inspection or locking of the cover, ensuring airtightness during transport and reducing leakage accidents caused by forgetting to lock the cover.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
