Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical auxiliary instruments, in particular to a nursing waste collecting device and method for operating rooms. BACKGROUND

[0002] The nursing waste collecting device for operating rooms is a special device designed for operating rooms, which is used to standardize the collection, pretreatment and preliminary disposal of medical waste generated during the operation process.

[0003] The traditional nursing waste collecting device for operating rooms has the following problems: A large amount of mixed liquid is generated during the operation process, which cannot be directly discharged into the natural environment or urban sewage network. Direct discharge of untreated operation mixed liquid will have disastrous consequences. It will pollute surface water and groundwater, cause deterioration of water quality, and affect the safety of drinking water for surrounding residents. Therefore, the mixed liquid can be stratified by centrifugation; However, the heat generated during centrifugation is often considered as a useless "by-product" and is wasted into the environment, resulting in a great waste of energy, which needs to be improved; At the same time, in addition to a large amount of complex mixed liquid generated during the operation process, used gauze and dressings are also the key objects of medical waste treatment. These gauze and dressings, which have absorbed a large amount of blood and tissue fluid, not only carry pathogens, but also may contain drug residues. If not properly treated, they will also pose a threat to the environment and health; And the traditional ordinary waste is treated by landfill, which increases the occupation of land resources and the risk of soil pollution; if incineration is used, it will increase the emission of harmful gases.

[0038] In a preferred embodiment, a method for using a nursing waste collecting device for operating room comprises the following steps: I. Classifying and putting the waste into the waste collecting device, specifically comprising: Step S1: When the medical staff needs to put the waste such as gauze and surgical mixed liquid, the hand is close to the infrared sensor 19 at the top of the corresponding put-in port, so that the infrared sensor 19 detects the infrared signal reflected by the hand to determine that there is an object close, and then sends a start signal to the electric telescopic cylinder 18 or the double-shaft independent control motor 22; Step S2: If the put-in port is the gauze collecting box 3, the electric telescopic cylinder 18 can drive the cover plate one 16 to rotate after receiving the signal, so as to open the gauze collecting box 3. If the put-in port is the liquid collecting box 4 or the solid collecting box 5, the double-shaft independent control motor 22 can drive the shaft one 23 or the shaft two 24 to rotate after receiving the signal, so as to drive the connecting block 25 to drive the cover plate two 17 to rotate, thereby completing the opening work of the liquid collecting box 4 or the solid collecting box 5, so that the medical staff can put the corresponding waste into the put-in port, put the gauze into the gauze collecting box 3, put the surgical mixed liquid into the liquid collecting box 4, and put the ordinary waste that needs to be heated into the solid collecting box 5, so that the corresponding waste delivery work can be completed according to the different types of waste; Step S3: After the waste delivery is completed, when the infrared sensor 19 does not detect the object, the electric telescopic cylinder 18 or the double-shaft independent control motor 22 can drive the cover plate one 16 or the cover plate two 17 to complete the reset, respectively, and make them in the closed state to avoid the escape of peculiar smell; II. Preprocessing of the gauze by the waste collecting device, specifically comprising: Step S1: Preliminary solid-liquid separation: after the gauze is put into the gauze collecting box 3, it first contacts the filter plate 15, so that the filter plate 15 can preliminarily filter the liquid blood and tissue fluid adhered to the gauze, so that the liquid falls into the bottom of the inner wall of the gauze collecting box 3, and the gauze is left on the top of the filter plate 15; Step S2: extrusion dehydration: by driving motor 1401 start, can make the drive shaft 1402 in rotation, extrusion plate two 1404 to the direction of extrusion plate one 1403 rotation, and the two contact can be put on the gauze collection box 3 inner wall gauze extrusion, and then can gradually extrude the blood and tissue fluid adsorbed in the gauze; Step S3: separation is completed: after the extrusion plate one 1403 and extrusion plate two 1404 extrusion, the blood, tissue fluid left in the gauze is further extruded, and the extruded liquid falls into the inner wall bottom of gauze collection box 3 through filter plate 15, and the gauze is left on the top of filter plate 15, realizing efficient separation of gauze and liquid, and when the liquid level sensor 26 detects that the liquid in the inner wall bottom of gauze collection box 3 exceeds the limit value, a signal will be emitted, which can make the suction pump 20 start working and make the suction pump 20 adsorb the liquid in the inner wall bottom of gauze collection box 3 to the inner wall of conveying pipe 21 and transport it to the inner wall of protective shell 9; Three, liquid centrifugal treatment, specifically including: Step S1: the liquid in gauze collection box 3 is adsorbed to conveying pipe 21 by suction pump 20, and is transported to lower hopper 605 in liquid collection box 4 through conveying pipe 21, then centrifugal motor 601 is started, and centrifugal motor 601 drives rotating area 602 to rotate, and then drum 603 rotates at high speed in lower hopper 605, so that the centrifugal force generated by the high-speed rotation of drum 603 causes the surgical mixed liquid in lower hopper 605 to stratify according to density difference: ① the components with larger density move to the bottom of drum 603; ② the components with smaller density gather on the upper layer of drum 603; to realize stratified separation of mixed liquid; Step S2: after stratification, the stratified liquid in drum 603 can be transported to detection cavity 609 by starting electric control valve 614, and color difference instrument 613 built in detection cavity 609 captures the light signal of the liquid, converts it into "Lab value", and compares it with the preset "surgical centrifugal liquid color database" to automatically determine the type of liquid, and after determination, starts conveying pump 611 to transport different types of liquid to catheter needle 612 through shunt pipe 610, and then stores the liquid after connecting with different infusion bags through catheter needle 612, so as to complete classification and collection; Four, heat recovery treatment, specifically including: Step S1: when centrifugal motor 601 operates, a large amount of heat energy is generated by mechanical parts, and because heat conduction shell 802 is attached to the outer wall of centrifugal motor 601 to adsorb heat energy, and heat preservation shell 801 isolates heat loss, the heat generated by the operation of centrifugal motor 601 can be accumulated in heat conduction shell 802; Step S2: At this time, the circulating pump 806 is started to suck the heat conducting medium in the storage cavity 10 to the liquid inlet pipeline 804 and deliver it to the finned heat exchanger 803, so that the heat conducting medium absorbs the heat collected by the heat conducting shell 802 in the finned heat exchanger 803, and then is delivered to the heating pipe 807 through the liquid outlet pipeline 805, and then the heated heat conducting medium is transmitted back to the inside of the storage cavity 10 through the return pipeline 809, forming a circulating return flow, ensuring uniform heat distribution; Step S3: When the heating pipe 807 transmits part of the heat to the heating cavity 11 in the solid collection box 5 to increase the temperature in the heating cavity 11, the ordinary waste such as plastic packaging and paper placed in the heating cavity 11 can be softened and deformed at high temperature, greatly reducing the volume, realizing waste volume reduction, and reducing the difficulty of subsequent treatment and storage.

10. A method of using a surgical waste collection device for operating rooms, characterized in that, Includes the following steps: I. Dispose of waste in the waste collection system according to its classification, specifically including: Step S1: When medical staff need to dispose of waste, they bring their hands close to the infrared sensor (19) on the top of the corresponding disposal port. The infrared sensor (19) detects the infrared signal reflected by the hand and determines that an object is approaching. Then it sends a start signal to the electric telescopic cylinder (18) or the dual-axis independent control motor (22). Step S2: If the inlet is a gauze collection box (3), the electric telescopic cylinder (18) can receive the signal and its telescopic end can drive the cover plate one (16) to rotate, thereby opening the gauze collection box (3); if the inlet is a liquid collection box (4) or a solid collection box (5), the dual-axis independent control motor (22) can receive the signal and drive the rotating shaft one (23) or rotating shaft two (24) to rotate, so that the connecting block (25) can drive the cover plate two (17) to rotate, thereby completing the opening of the liquid collection box (4) or the solid collection box (5), so that medical staff can put the corresponding waste into the inlet, put gauze into the gauze collection box (3), surgical mixture into the liquid collection box (4), and ordinary waste that needs to be heated into the solid collection box (5), thereby completing the corresponding waste delivery work according to the different types of waste; Step S3: After the waste is delivered, if the infrared sensor (19) does not detect an object, the electric telescopic cylinder (18) or the dual-axis independent control motor (22) can drive the cover plate one (16) or the cover plate two (17) to reset and keep them in the closed state to prevent odor from escaping. II. The waste collection device pre-treats the gauze, specifically including: Step S1: Preliminary solid-liquid separation: After gauze is put into the gauze collection box (3), it first contacts the filter plate (15), which allows the filter plate (15) to preliminarily filter the liquid (blood, tissue fluid) on the gauze, so that the liquid falls into the bottom of the inner wall of the gauze collection box (3) and the gauze remains on the top of the filter plate (15). Step S2: Squeezing and dehydration: By starting the drive motor (1401), the drive shaft (1402) can rotate and drive the second squeezing plate (1404) to rotate in the direction of the first squeezing plate (1403). After the two come into contact, they can squeeze the gauze placed on the inner wall of the gauze collection box (3), thereby gradually squeezing out the blood and tissue fluid adsorbed in the gauze. Step S3: Separation complete: After the squeezing plates 1 (1403) and 2 (1404) squeeze each other, the blood and tissue fluid remaining in the gauze can be squeezed out further, and the squeezed liquid falls into the bottom of the inner wall of the gauze collection box (3) through the filter plate (15), while the gauze remains on the top of the filter plate (15), thus achieving efficient separation of the gauze and the liquid. When the liquid level sensor (26) detects that the liquid at the bottom of the inner wall of the gauze collection box (3) exceeds the limit value, it will send a signal to start the suction pump (20) and make the suction pump (20) adsorb the liquid at the bottom of the inner wall of the gauze collection box (3) to the inner wall of the delivery pipe (21) and deliver it to the inner wall of the protective shell (9). III. Liquid centrifugation treatment, specifically including: Step S1: The liquid in the gauze collection box (3) is drawn into the delivery pipe (21) by the suction pump (20), and then delivered to the hopper (605) in the liquid collection box (4) through the delivery pipe (21). Subsequently, a signal is emitted to start the centrifugal motor (601), and the centrifugal motor (601) drives the rotating area (602) to rotate, thereby causing the drum (603) to rotate at high speed in the hopper (605). The high-speed rotation of the drum (603) generates centrifugal force, causing the surgical mixture in the hopper (605) to separate into layers according to density differences. ① The denser components move towards the bottom of the drum (603); ② The components with lower density aggregate in the upper layer of the drum (603); thereby achieving the stratification and separation of the mixed liquid; Step S2: After stratification, the liquid in the drum (603) can be transported to the detection chamber (609) by activating the electronically controlled valve (614). The colorimeter (613) built into the detection chamber (609) captures the light signal of the liquid, converts it into "Lab value", and compares it with the preset "surgical centrifugal liquid color database" to automatically determine the liquid type. After determination, the delivery pump (611) is activated to transport different types of liquids through the diversion pipe (610) to the catheter needle (612). The liquid is then stored after being connected to different infusion bags through the catheter needle (612). This completes the classified collection and ensures that liquids that meet emission standards are separated from pollutants. IV. Heat recovery treatment, specifically including: Step S1: When the centrifugal motor (601) is running, the mechanical parts generate a lot of heat energy. Because the heat-conducting shell (802) is attached to the outer wall of the centrifugal motor (601), it absorbs the heat energy, while the heat-insulating shell (801) isolates the heat loss, so that the heat generated when the centrifugal motor (601) is running can accumulate in the heat-conducting shell (802). Step S2: At this time, start the circulation pump (806) to draw the heat transfer medium in the storage chamber (10) into the inlet pipe (804) and deliver it to the finned heat exchanger (803). After the heat transfer medium absorbs the heat accumulated in the heat transfer shell (802) in the finned heat exchanger (803), it is delivered to the heating tube (807) through the outlet pipe (805). Then, the heated heat transfer medium is transferred back to the interior of the storage chamber (10) through the return pipe (809) to form a circulation return and ensure uniform heat. Step S3: When the heating tube (807) transfers some heat to the heating chamber (11) inside the solid collection box (5), the temperature inside the heating chamber (11) will rise, which will soften and deform the ordinary waste placed inside the heating chamber (11) at high temperature, and reduce its volume significantly, thereby reducing the volume of waste and lowering the difficulty of subsequent processing and storage.
