Description

Technical Field

[0001] The invention relates to the field of medical cleaning instruments, in particular to an anti-infection device for recycling used instruments for operating room nursing. Background Art

[0002] Nursing equipment refers to instruments, equipment, instruments, in vitro diagnostic reagents and calibrators, materials, and other similar or related items used directly or indirectly on the human body. The Sterilization Supply Center is primarily responsible for routine hospital disinfection and the sterilization of surgical instruments. Surgical instruments often contain a large amount of patient fluids, which are difficult to clean after solidifying. To prevent cross-infection and viral and bacterial infections, hospitals strictly require medical staff to disinfect frequently used nursing supplies, such as wipes, thermometers, tourniquets, and humidifier bottles, before and after surgery, daily routine rounds, physical examinations, and nursing care. Currently, manual cleaning is the primary method, followed by high-temperature sterilization. Manual cleaning can easily scratch the blade of a scalpel, causing injury to medical staff and increasing the risk of infectious bacteria.

[0003] Controlling hospital infections and preventing the occurrence of hospital infections are the main tasks of hospitals. Although hospitals have relatively complete disinfection equipment and systems, hospital infections still occur. These infections are often caused by surgical and nursing equipment and other equipment coming into contact with pathogens before being put into use, leading to the occurrence of infections. Existing medical instrument disinfection devices cannot effectively sterilize and disinfect, and cannot meet medical use requirements. Summary of the Invention

[0059] The telescopic driving component includes: a piston channel is provided inside the movable plate of the device, a first piston is provided in the piston channel, the first piston reciprocates along the length direction of the piston channel, and the piston channel is connected to the air pump through an air guide pipe.

[0060] The technical solutions provided by the embodiments disclosed in the present invention may have the following beneficial effects:

[0061] First: Use the external gas filling and pumping device to introduce gas into the sealed cavity through the air guide tube, the internal pressure of the sealed cavity increases, and the folded pleated layer increases with the inflation amount. After it is fully expanded, the exhaust operation is performed, the internal pressure of the sealed cavity decreases, the filled sealed cavity gradually shrinks, the folded pleated layer returns to the folded state, and the air is pumped out, making the bottom of the cleaning bag uneven. During the repeated inflation and pumping of the sealed cavity of the cleaning bag, the cleaning liquid in the cleaning bag always generates fluctuations at the same time as the movement of the bottom of the cleaning bag, flushing the surface of the used utensils immersed in the cleaning bag, thereby achieving the cleaning operation;

[0062] Second: use the external gas filling and pumping device to pass gas into the spherical airbag through the air guide tube, the internal pressure of the spherical airbag increases, and as the inflation volume of the spherical airbag increases, after it is fully expanded, the spherical airbag is squeezed from all sides toward the elastic keel, and the elastic keel is deformed. At this time, since the bracket is arranged on the surface of the spherical airbag, the spherical airbag is deformed and the bracket deviates from the central axis position, and the bracket drives the cleaning tray connected to its upper end to perform eccentric movement, the deviation angle is 15°-20°, with 20° as the optimal angle, driving the cleaning tray to achieve 20-30 degrees of eccentricity, and the deviation angle of the cleaning tray is 25 degrees optimal, which can drive the cleaning liquid in the cleaning tray to generate fluctuations, relatively hit the surface of the used utensil, and scrub it, and the deviation angle is not yet to the angle where the cleaning liquid splashes out of the cleaning tray 902;

[0063] Third: the telescopic fixing member includes an inner rod and an outer tube, the inner rod is fixed to the telescopic fixing member, the outer tube is sleeved on the inner rod, and the outer tube rises or falls along the axial direction of the inner rod, and the rising height of the outer tube is slightly smaller than the sum of the outer tube and the inner rod. A clamping ball is provided at the upper end of the outer tube. When the supporting assembly descends, the clamping ball enters the embedding cavity on the lower surface of the annular connecting frame under the extrusion of the annular connecting frame. In the process of the clamping ball entering the embedding cavity, the valve first adheres to the embedding cavity and finally, due to the recovery of elastic deformation, it detaches from the clamping ball and returns to the clamping opening of the embedding cavity. Since the mounting ball is an elastic ball with recovery ability, the maximum radius of the mounting opening is slightly smaller than the maximum radius of the elastic ball. After the clamping ball enters the embedding cavity, there is no external force greater than the elastic deformation of the clamping ball itself, it cannot detach from the clamping ball and exit the clamping opening, thereby realizing the relative fixation of the used utensil storage basket and the annular connecting frame;

[0064] Fourth: The quality of the ball valve is random. The ball valve is made of stainless steel. After the second connecting hole of the spherical airbag is connected to the external gas pumping device, the gas pumping device is started to inflate the spherical airbag. When the spherical airbag is filled, the air pressure continues to increase. The ball valve is pushed away from the connection between the cylindrical cavity and the spherical cavity by the pressure. The exhaust hole connects the space between the spherical airbag and the air pressure regulating cavity, and the gas is introduced into the air pressure regulating cavity. Since the quality of the air valve is random, the required lifting pressure is different, and the randomness of the pressure relief position leads to the random deformation position of the spherical airbag. Since the spherical airbag has the function of supporting the bracket, the deformation of the spherical airbag causes the bracket to generate centrifugal force, and the cleaning tray located at the upper end of the bracket shakes centrifugally;

[0065] Fifth: A first cavity is provided inside the tool receiving movable plate, and a mounting hole is provided on a surface of the tool receiving movable plate, which is in communication with the first cavity. One end of the elastic plate is inserted into the first cavity through the mounting hole, while the other end of the elastic plate remains outside the mounting hole. The elastic plate is naturally curled to block the accumulated used tools and prevent them from sliding into the internal cavity of the workbench.

[0066] Sixth: The embedding cavity is arranged in the annular connecting frame, and the lower surface of the annular connecting frame is provided with a clamping opening connected to the interior of the embedding cavity. At least one pair of valves is provided at the clamping opening, and the material of the valve has a certain friction force and a certain hardness.

[0096] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0097] The technical solution provided by the disclosed embodiment of the present invention relates to an anti-infection device for recycling used instruments for operating room care, and particularly to the field of medical instruments. In the related art, controlling infections in hospitals and preventing the occurrence of hospital infections are the main tasks of hospitals. Although hospitals have relatively complete disinfection equipment and systems, hospital infections still occur. These infections are often caused by surgical care instruments and other equipment coming into contact with pathogens before being put into use, leading to the occurrence of infections. Existing medical instrument disinfection devices cannot effectively perform sterilization and disinfection and cannot meet medical use requirements.

[0099] Preferably, Figure 3 and Figure 4 As shown, the device delivery unit includes: a robotic arm 301; a receiving portion 302, the receiving portion 302 is arranged at the distal end of the robotic arm 301, at least one pair of mutually parallel device levers 303, at least one pair of mutually parallel device levers 303 is fixedly connected to the receiving portion 302; an elastic bending member 304, the elastic bending member 304 is fixedly connected to the adjacent device levers 303, and the highest point of the convex portion of the elastic bending member 304 is higher or lower than the line connecting the ends of the adjacent device levers 303.

[0100] The edge of the instrument inlet 102 on the upper surface of the workbench 101 is recessed downward to form an instrument retaining groove 103. The instrument retaining groove 103 is used by medical staff to prevent used instruments in the operating room from being scattered to other areas of the workbench 101. It facilitates the robotic arm 301 to drive the instrument lever 303 to push the used instruments into the instrument retaining groove 103.

[0101] The hinged connection device receiving movable plate 106 is provided at the device inlet 102, and the device receiving movable plate 106 is provided with a device anti-fall unit.

[0103] Working principle:

[0104] When the used instruments for operating room care enter the instrument limiting groove 103, the weight borne by the instrument receiving movable plate 106 gradually increases due to the accumulation of quantity. After the downward gravity of the used instruments placed is greater than the anti-rebound force of the coil spring in the hinge, the instrument receiving movable plate 106 rotates downward from the horizontal position with the hinge as the axis, and the used instruments slide along the surface of the instrument receiving movable plate 106 to the position of the elastic plate 401 under the action of gravity. At this time, the elastic plate 401 prevents the used instruments from continuing to slide due to the presence of a certain curvature, and the used instruments accumulate at the connection between the elastic plate 401 and the instrument receiving movable plate 106, and stay there for a short time. At this time, the high-temperature spray unit is turned on to perform an initial wash and spray on the used instruments here.

[0105] After the initial washing and spraying of the used utensil is completed, the air pump 405 is started. The air pump 405 draws air from the piston channel 402, the internal pressure of the piston channel 402 increases, and the first piston 403 is subjected to pressure and moves in a direction away from the elastic plate 401, driving the elastic plate 401 to extend into the piston channel 402. On the contrary, the air pump 405 inflates the piston channel 402, the internal pressure of the piston channel 402 increases, the first piston 403 is pushed and moves in a direction close to the elastic plate 401, driving the elastic plate 401 to protrude out of the piston channel 402.

[0106] Preferably, Figures 1 to 3 As shown, the high-temperature spray unit includes: a steam generator 501, which is located at the lower part of the cavity structure 104 of the workbench 101; a water heater 502, a section of the water heater 502 is connected to the steam generator 501, and a preliminary washing spray head 503 is provided at the water outlet end of the water heater 502. It should be further pointed out that a first cavity 1061 is provided inside the appliance receiving movable plate 106, and a mounting hole connected to the inside of the first cavity 1061 is provided on the surface of the appliance receiving movable plate 106. One end of the elastic plate 401 is inserted into the first cavity 1061 from the mounting hole, and the other end of the elastic plate 401 remains outside the mounting hole. The elastic plate is curled in its natural state, which blocks the accumulated used utensils to prevent them from sliding into the internal cavity 104 of the workbench 101.

[0107] Preferably, Figure 7 and Figure 8 as well as Figure 15 As shown, the utensil cleaning unit of embodiment 1 includes:

[0108] The utensil cleaning unit includes: a first auxiliary mounting seat 601 and a second auxiliary mounting seat 602, and a rotating assembly. It should be further noted that:

[0112] Furthermore, the cleaning chamber assembly is provided on the connecting ring 603. It should be further noted that the cleaning chamber assembly includes:

[0113] like Figure 15 As shown, the cleaning bag 701, the opening surface of the cleaning bag 701 is arranged on the upper surface of the connecting ring 603; the lower surface of the cleaning bag 701 is a double-layer structure.

There is a sealed cavity 7013 between the flat and smooth layer and the pleated and folded layer, and the outer layer 7011 is provided with a first connecting hole connected to the air duct of the external gas filling and pumping device.

[0114] Working principle:

[0115] An external gas filling and pumping device is used to pass gas into the sealed cavity through the air duct, and the internal pressure of the sealed cavity 7013 increases, and the folded pleated layer increases with the inflation amount. After it is fully expanded, the exhaust operation is performed, and the internal pressure of the sealed cavity 7013 decreases, the filled sealed cavity gradually shrinks, and the folded pleated layer returns to the pleated state, and air is pumped out, making the bottom of the cleaning bag 701 uneven. During the repeated process of inflation and pumping of the sealed cavity of the cleaning bag 701, the cleaning liquid in the cleaning bag always fluctuates at the same time as the movement of the bottom of the cleaning bag 701, flushing the surface of the used utensils immersed in the cleaning bag 701 to achieve the cleaning operation.

[0116] Preferably, an auxiliary sliding assembly is further included, and the auxiliary sliding assembly includes: a first auxiliary mounting seat 601 and a second auxiliary mounting seat 602, wherein a groove 6011 is provided on a side surface of the first auxiliary mounting seat 601 close to the connecting ring, and the edge of the connecting ring 603 extends into the groove 6011, and a first auxiliary mechanism is provided in the groove 6011, and the first auxiliary mechanism is attached to the surface of the portion of the connecting ring 603 that enters the groove 6011; a second auxiliary mechanism is provided on the upper surface of the second auxiliary mounting seat 602, and the second auxiliary mechanism is attached to the portion of the connecting ring projected on the second auxiliary mounting seat 602. The lower surface should be further pointed out that the first auxiliary mounting seat 601 can be a cylindrical or rectangular columnar structure; the first auxiliary mechanism includes an upper slide 2301 arranged on the upper surface of the connecting ring and a lower slide 2302 on the lower surface of the connecting ring, and an upper ball 2303 and a lower ball 2304 that can roll 360 degrees are embedded in the groove 6011. The upper ball is embedded in the upper slide and the lower ball is embedded in the lower slide to assist the connecting ring to rotate smoothly. The second auxiliary mechanism includes a second lower ball 24 arranged on the surface of the second mounting seat 601, and the second lower ball 24 is also embedded in the lower slide to assist the connecting ring to rotate smoothly.

[0117] Hanging ropes 801 are provided at equal angles on the edge of the cleaning bag 701 , and baffles 802 for hanging the hanging ropes are provided at equal angles on the upper surface of the connecting ring 603 .

[0118] like Figures 16 to 19 As shown, the utensil cleaning unit of the second embodiment includes:

[0119] A retractable airbag assembly, the retractable airbag assembly is arranged on the lower surface of the cavity structure 104 of the workbench 101; a bracket 901, the bracket 901 is arranged on the surface of the retractable airbag assembly; a cleaning tray 902, the lower surface of the cleaning tray 902 is movably connected to the upper end of the bracket 901, and the cleaning tray 902 is inclined 15°-20° along the upper end of the bracket.

[0120] Furthermore, the collapsible airbag assembly includes:

[0121] A spherical airbag 903 is provided with an elastic keel frame 904 inside the spherical airbag 903; the elastic keel frame 904 is fixedly connected to the lower surface of the spherical airbag 903 via a connecting rod; a second connection hole is provided on the surface of the spherical airbag 903 for connecting to an air guide tube of an external gas filling and pumping device;

[0122] It should be further noted that the lower surface of the cleaning tray 902 is a horizontally upwardly concave arc-shaped groove, the center of which is provided with a spherical cavity. The upper end of the bracket 901 is provided with a connecting ball 905, which is embedded in the spherical cavity. After the bracket 901 is eccentric, the cleaning tray 902 can move relative to the connecting ball 905 to achieve an eccentric movement of 20-30 degrees.

[0123] It should be further noted that a pressure regulating layer 906 is provided on the surface of the spherical airbag 903, and a pressure regulating cavity 907 is formed between the pressure regulating layer 906 and the spherical airbag 903. The projection of the pressure regulating layer 906 on the surface of the spherical airbag 903 is the pressure regulating area, and a pressure regulating valve group is provided in the pressure regulating area.

[0124] It should be further pointed out that if Figure 23 As shown, an elastic keel 25 is also provided in the air pressure regulating chamber 907. The elastic keel 25 is squeezed and deformed, and plays a certain supporting role on the spherical airbag 903. However, the elastic deformation will also cause the support rod set on the surface of the spherical airbag 903 to be centrifugal at a certain angle, which assists the deformation of the spherical airbag 903 and exerts force on the support rod.

[0125] The gas pressure regulating valve group includes: Figure 24As shown, at least one exhaust hole 1001, at least one of the exhaust holes 1001 is arranged on the surface of the air pressure regulating area and is connected to the interior of the spherical airbag 903, the exhaust hole 1001 is a connecting hole with a spherical cavity at the upper part and a cylindrical cavity at the lower part; a ball valve 1002, the ball valve 1002 is arranged in the spherical cavity of the exhaust hole 1001; the ball valve 1002 is connected to the inner wall of the exhaust hole through a reset spring 25, and also includes a constant exhaust valve, a horizontal exhaust valve is provided on the surface of the spherical airbag, and the constant exhaust valve is always in a conducting state.

[0126] It should be further pointed out that the quality of the ball valve 1002 is random. The ball valve 1002 is made of stainless steel. After the second connecting hole of the spherical airbag 903 is connected to the external gas pumping device, the gas pumping device is started to inflate the spherical airbag 903. When the spherical airbag 903 is filled, the air pressure continues to increase. The ball valve 1002 leaves the connection between the cylindrical cavity and the spherical cavity under the push of the pressure. The exhaust hole 1001 connects the space between the spherical airbag and the air pressure regulating cavity, and introduces the gas into the air pressure regulating cavity 907. Since the quality of the air valve is random, the required lifting pressure is different, and the randomness of the pressure relief position causes the random deformation position of the spherical airbag 903. Since the spherical airbag 903 has the function of supporting the bracket 901, the deformation of the spherical airbag 903 causes the bracket to generate centrifugal force, and the cleaning tray 902 located at the upper end of the bracket 901 shakes centrifugally.

[0127] Working principle:

[0128] The air is introduced into the spherical airbag 903 through the air guide tube by an external gas filling and pumping device, and the internal pressure of the spherical airbag 903 increases. As the amount of inflation increases, the spherical airbag 903 is fully expanded, and the spherical airbag 903 is squeezed from all sides toward the elastic keel 904, and the elastic keel 904 is deformed. At this time, since the bracket 901 is arranged on the surface of the spherical airbag 903, the spherical airbag 903 is deformed, and the bracket 901 deviates from the central axis position, and the bracket 901 drives the cleaning tray 902 connected to its upper end to perform eccentric movement. The deviation angle is 15°-20°, with 20° being the optimal angle, which drives the cleaning tray to achieve an eccentricity of 20-30 degrees. The deviation angle of the cleaning tray 902 is optimal at 25 degrees, which can drive the cleaning liquid in the cleaning tray 902 to fluctuate and hit the surface of the used utensils for scrubbing. The deviation angle is not yet to the angle where the cleaning liquid splashes out of the cleaning tray 902.

[0129] It should be further pointed out that an annular fixing seat is provided at the connection between the spherical airbag 903 and the lower surface of the cavity structure 104 of the workbench 101. The annular fixing seat confines the spherical airbag 903 within an annular range, and the lower part of the spherical airbag 903 is stable, so that only a relatively stable eccentric force is generated.

[0130] It should be further pointed out that a first groove body for embedding the air guide tube is provided on the side surface of the cavity structure 401 of the workbench 101 .

[0131] Further, if Figure 11 and Figure 12 As shown, the spray disinfection unit includes: a carrying plate 1101, which is arranged on the upper surface of the cavity structure 104 of the workbench 101; a horizontal transport component, which is arranged below the carrying plate 1101; a linear motor 1102, which is arranged on the carrying plate 1101 and cuts through the horizontal transport component; and an electromagnetic adsorption component, which is connected to the driving end of the linear motor 1102.

[0132] It should be further pointed out that the horizontal transport assembly includes: a base plate 1103, the base plate 1101 is fixedly connected to the lower surface of the carrier plate 1101 through at least one pair of mounting posts 21; at least one pair of air guide channels 1104, a pair of the air guide channels 1104 is arranged inside the base plate 1103 and parallel to the extension direction of the base plate 1103; at least one pair of piston rods 1105, the piston rods 1105 are inserted into the air guide channels 1104 and reciprocate along the length direction of the air guide channels 1104; a pair of slide grooves 1106, a pair of the slide grooves 1107 and 1108. 106 is arranged on the lower surface of the base plate 1103, and the axes of the pair of slide grooves 1106 are parallel to the symmetry axes of the pair of piston rods 1105; a pair of sliders 1107, the sliders 1107 are embedded in the slide grooves 1106, and the lower ends of the sliders 1107 extend out of the slide grooves 1106, and the pair of sliders 1107 are fixedly connected by pushing rods 1108, and the pair of sliders 1107 reciprocate along the length direction of the slide grooves 1106 at the same time, and the lower surfaces of the pair of sliders are both provided with a first electromagnet 1109 for adsorbing the used utensil storage basket.

[0133] Furthermore, a push rod 1108 is provided, one end of which is fixedly connected to one end of the piston rod 1105 extending out of the air guide channel 1104 ; a pair of push rods 1108 are fixedly connected to opposite side surfaces of the slider 1107 .

[0134] It should be further pointed out that if Figure 11 and Figure 12 As shown, the electromagnetic adsorption component includes:

[0135] A bracket 1201 is provided at the telescopic end of the linear motor 1102;

[0136] A second electromagnet 1202 is provided on the lower surface of the bracket 1201;

[0137] An annular connecting frame 1203, wherein a metal plate for connecting to the second electromagnet 1202 is provided at the center of the annular connecting frame 1203;

[0138] The supporting mechanism is arranged on the lower surface of the annular connecting frame 1203.

[0139] It should be further pointed out that if Figure 11 and Figure 6 As shown, the supporting institutions include:

[0140] At least one embedding cavity 1301, at least one of the embedding cavity 1301 is arranged in the annular connecting frame 1203, the lower surface of the annular connecting frame 1203 is provided with a clamping opening connected to the interior of the embedding cavity 1301, and at least one pair of valves 1302 are provided at the clamping opening, and the material of the valve 1302 has a certain friction and a certain hardness.

[0141] It should be further noted that the used utensil storage basket includes: a U-shaped frame 1401; a storage basket 1402, the side surface of which is fixedly connected to the U-shaped frame; the U-shaped frame includes a metal body and an anti-corrosion layer wrapped around the metal body. The metal body is an iron metal frame; a telescopic fixing member, which is disposed at the center of the lower surface of the inner cavity of the storage basket;

[0142] It should be further pointed out that the telescopic fixing member includes an inner rod 1501 and an outer tube 1502. The inner rod is fixed to the telescopic fixing member, and the outer tube is sleeved on the inner rod. The outer tube rises or falls along the axial direction of the inner rod. The rising height of the outer tube is slightly less than the sum of the outer tube and the inner rod. A clamping ball 1503 is provided at the upper end of the outer tube. When the supporting mechanism descends, the clamping ball enters the embedding cavity on the lower surface of the annular connecting frame under the squeezing of the annular connecting frame. In the process of the clamping ball entering the embedding cavity, the valve first adheres to the embedding cavity, and finally, due to the recovery of elastic deformation, it detaches from the clamping ball and returns to the clamping port of the embedding cavity. Since the mounting ball is an elastic ball and has recovery ability, the maximum radius of the mounting port is slightly smaller than the maximum radius of the elastic ball. After the clamping ball enters the embedding cavity, it cannot detach from the clamping ball and exit the clamping port without an external force greater than the elastic deformation of the clamping ball itself, thereby realizing the relative fixation of the used utensil storage basket and the annular connecting frame.

[0143] It should be further pointed out that the inner wall of the outer tube is provided with an internal thread, and the outer wall of the inner rod is provided with an external thread, and the outer tube is relatively fixed to the inner rod through the internal thread and the external thread.

[0144] Working principle: Before using the device, the staff will screw the outer tube, and the outer tube will rise along the inner rod. The height of the outer tube is slightly higher than the plane of the opening of the storage basket. Use disinfectant to cover 4 / 5 of the storage basket to clean the used utensils in the storage basket. After cleaning is completed, start the linear motor to drive the electromagnetic adsorption component fixedly connected to the telescopic end of the linear motor to move towards the cleaning tray until the clamping sphere at the upper end of the bracket is immersed in the embedded cavity of the annular connecting frame of the electromagnetic adsorption component. Start the linear motor in the reverse direction, and the telescopic end of the linear motor will retract, driving the used utensils to be collected. The basket moves vertically upward until the used utensil storage basket reaches the bottom of a pair of sliders. The first electromagnet is energized while the second electromagnet is de-energized. At this time, the external air pump is started, and air enters the air guide channel, pushing the piston tube to move along the length of the air guide channel, driving the connecting rod fixedly connected to the piston tube to move, and driving the slider fixedly connected to the connecting rod to move synchronously. The annular connecting frame holding a number of used utensil storage baskets under the pair of sliders moves horizontally into the high-temperature steam sterilizer. At this time, the first electromagnet is de-energized, and the sealed door of the high-temperature steam sterilizer is closed for high-temperature steam sterilization and drying.
