Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a recovery device for spilled chemotherapy liquid. Background Art

[0002] The infusion of chemotherapy solutions is one of the common technical operations for treating tumors in the medical field. Medical staff may spill chemotherapy solutions due to accidental contact or operational errors during the process of adding chemotherapy solutions, replacing chemotherapy solutions, and plugging and unplugging infusion devices. Chemotherapy solutions are different from general solutions. Extravasation of chemotherapy drugs can cause skin reactions, such as burning, stinging, blistering, nodules, skin discoloration, etc. Severe cases can even cause inflammatory reactions and necrosis of subcutaneous tissue. If ulceration or infection occurs, it may also lead to a series of conditions such as limb dysfunction, scar formation, and disfigurement. Therefore, if the spilled chemotherapy solutions are not cleaned up in time, it will bring safety hazards to medical staff, patients or their families.

[0003] In the prior art, for the cleaning and recovery of chemotherapy liquid caused by operational errors, medical staff generally use the traditional method of wearing medical gloves and then absorbing and wiping with gauze. This cleaning method is slow and inefficient when a large amount of chemotherapy liquid is spilled, and it also increases the time that medical staff are in close contact with the chemotherapy liquid, thereby increasing the risk of contamination. Therefore, in order to solve this problem, a recovery device for spilled chemotherapy liquid is proposed. Utility Model Content

[0004] The utility model collects the spilled chemotherapy liquid by setting a recovery device, and collects it through an air pump and a recovery device, so as to avoid close contact between medical staff and the chemotherapy liquid, thereby reducing the risk of contamination of the liquid and protecting the medical staff. Based on this, the utility model is completed.

[0005] The utility model provides a recovery device for spilled chemotherapy drugs, comprising a base plate, a recoverer fixedly installed on the top of the base plate, a suction pipe and a liquid inlet pipe passing through the top of the recoverer, the top of the suction pipe is connected to an air pump fixed on the recoverer through a pipeline, a No. 1 corrugated pipe is fixedly connected to the top of the liquid inlet pipe, a long arm pipe with a hollow inner cavity is fixedly connected to the end of the No. 1 corrugated pipe away from the liquid inlet pipe, a liquid absorption plate is hingedly installed on the bottom of the long arm pipe, hoses connected to the liquid absorption plate are fixedly connected below both sides of the long arm pipe, a groove is provided at the bottom of the liquid absorption plate, and a plurality of suction nozzles are arranged in the groove.

[0006] A track plate is fixedly installed on the left side of the inner cavity of the recoverer, a slider is slidably installed on the right side of the track plate, a splash plate is fixedly installed on the right side of the slider, a plurality of buoyancy balls are fixedly installed on the bottom of the splash plate, an air intake ring is connected through the right side of the recoverer, a No. 2 bellows is fixedly connected to the inner end of the air intake ring, a connecting pipe is fixedly installed on the top of the splash plate below the suction pipe, and the connecting pipe is fixedly connected to the No. 2 bellows.

[0007] Furthermore, a transparent observation window is provided on the front wall of the recycler, and the bottom of the inner cavity of the recycler is designed as a structure with two sides converging and tilting toward the middle.

[0008] Furthermore, a drain pipe is fixedly installed below the front wall of the recoverer, an opening and closing valve is arranged on the drain pipe, and a leakage hole connected to the drain pipe is arranged at the bottom of the inner cavity of the recoverer.

[0009] Furthermore, a placement seat is fixedly installed on the top of the bottom plate located on the left side of the recycler, a slot matching the liquid absorption plate is opened on the top of the placement seat, and the liquid absorption plate is snap-fitted and installed on the top of the placement seat.

[0010] Furthermore, a slide groove adapted to the slider is opened on the right side of the track plate, and the slider is slidably installed in the slide groove, and a limit rod with both ends fixedly connected to the slide groove is inserted and installed on the slider, and a slot adapted to the liquid inlet pipe is opened on the splash plate, and the bottom end of the liquid inlet pipe passes through the slot and extends to the bottom of the splash plate.

[0011] Furthermore, a whistle is fixedly connected to the outer side of the air intake ring, the top outer diameter of the connecting tube is matched with the bottom inner diameter of the straw, the top inner cavity of the connecting tube is connected with a trapezoidal sealing plug through a spring, and a trapezoidal groove matched with the trapezoidal sealing plug is opened in the top of the connecting tube, and an abutment rod is fixedly installed in the middle of the bottom inner cavity of the straw.

[0012] Compared with the prior art, the recovery device for spilled chemotherapy liquid provided by the utility model has the following technical advantages:

[0013] 1. In the present application, through the present design, when the chemotherapy liquid is accidentally spilled, the medical staff can quickly take out the pipette plate from the top of the placement seat by holding the long arm tube, and then press the pipette plate on the edge of the spilled chemotherapy liquid. At this time, the air pump is started to suck air into the recovery device through the pipette to generate negative pressure. When the recovery device generates negative pressure, the suction force of the negative pressure will pass through the liquid inlet pipe, No. 1 bellows, the long arm tube and the hose to the suction nozzle at the bottom of the pipette plate. At this time, the pipette plate is pushed along the direction of the spilled chemotherapy liquid, so that the medicine can be quickly absorbed into the recovery device for collection, thereby improving the cleaning efficiency. At the same time, it can also avoid the damage caused by the medical staff's hands directly cleaning the chemotherapy liquid being contaminated.

[0014] 2. In the present application, through the present design, when the chemotherapy liquid continues to enter the recovery device, the liquid level in the recovery device will rise. When the liquid level rises to the position of the splash guard, the splash guard will be lifted as a whole through the buoyancy ball. Before this process, a trapezoidal sealing plug is connected to the top of the connecting tube through a spring, which plays a sealing role, so that the outside air cannot enter the recovery device through the air intake ring, so as to ensure that the air pump can normally generate negative pressure in the recovery device to suck in the chemotherapy liquid. When the splash guard is lifted by the buoyancy until the top of the connecting tube at the top of the splash guard is inserted into the bottom end of the straw, the abutment rod at the bottom end of the straw will be inserted into the connecting tube and abut against the The trapezoidal sealing plug moves downward, and the airway of the connecting pipe is opened at this time, so that the suction pipe is connected with the connecting pipe, and the external air is sucked into the suction pipe through the air intake ring, the No. 2 bellows, and the connecting pipe, so that no negative pressure is generated in the recovery device, and the absorption of the chemical liquid is stopped to prevent the chemical liquid in the recovery device from being overloaded and the liquid level rising to the position of the suction pipe and being sucked into the air pump and sprayed to the outside. Of course, a whistle is also designed here. Since the whistle will make a sound due to the suction force, it can remind medical staff that the liquid in the recovery device is full. At this time, the medical staff can open the valve on the discharge pipe to discharge the liquid in the recovery device into the specified place.

A hose 10 connected to the liquid absorption plate 9 is fixedly connected to the lower part of both sides of the long arm tube 8. A groove 12 is provided at the bottom of the liquid absorption plate 9, and a plurality of suction nozzles 11 are arranged in the groove 12. A placement seat 21 is fixedly installed on the top of the bottom plate 1 located on the left side of the collector 2. A card slot matched with the liquid absorption plate 9 is provided on the top of the placement seat 21, and the liquid absorption plate 9 is card-connected and installed on the top of the placement seat 21.

[0024] Through the above design, when the chemotherapy solution is accidentally spilled, the medical staff can quickly remove the absorbent plate 9 from the top of the placement seat 21 by holding the long arm tube 8, and then press the absorbent plate 9 on the edge of the spilled chemotherapy solution. At this time, the air pump 5 is started to suck air into the recovery device 2 through the suction tube 4 to generate negative pressure. When the recovery device 2 generates negative pressure, the suction force of the negative pressure will pass through the liquid inlet pipe 6, the No. 1 bellows 7, the long arm tube 8 and the hose 10 to the suction nozzle 11 at the bottom of the absorbent plate 9. At this time, the absorbent plate 9 is pushed along the direction of the spilled chemotherapy solution, so that the solution can be quickly absorbed into the recovery device 2 for collection, thereby improving the cleaning efficiency. At the same time, it can also avoid the damage caused by the medical staff's hands directly cleaning the chemotherapy solution being contaminated.

[0025] Reference Figure 1 , 24.

[0026] Through the above design, when the chemotherapy liquid continues to enter the recovery device 2, the liquid level in the recovery device 2 will rise. When the liquid level rises to the position of the splash plate 15, the splash plate 15 will be lifted as a whole through the buoyancy ball 16. Before this process, since the top of the connecting tube 20 is connected to the trapezoidal sealing plug 22 by a spring, it plays a sealing role, so that the outside air cannot enter the recovery device 2 through the intake ring 17, so as to ensure that the air pump 5 can normally generate negative pressure in the recovery device 2 to suck in the chemotherapy liquid. When the splash plate 15 is lifted by the buoyancy until the top of the connecting tube 20 at the top of the splash plate 15 is inserted into the bottom end of the suction pipe 4, the abutment rod 23 at the bottom end of the suction pipe 4 will be inserted into the connecting tube 20 to abut against the ladder The shaped sealing plug 22 moves downward, and at this time the airway of the connecting pipe 20 is opened, so that the suction pipe 4 is connected with the connecting pipe 20, and the external air is sucked into the suction pipe 4 through the air intake ring 17, the second bellows 18, and the connecting pipe 20, so that no negative pressure is generated in the recovery device 2, and the absorption of the chemical liquid is stopped to prevent the chemical liquid in the recovery device 2 from being overloaded so that the liquid level rises to the position of the suction pipe 4 and is sucked into the air pump 5 and sprayed to the outside.

When the liquid level rises to the position of the splash plate 15, the splash plate 15 will be lifted as a whole through the buoyancy ball 16. Before this process, the top of the connecting tube 20 is connected to the trapezoidal sealing plug 22 by a spring, which plays a sealing role, so that the outside air cannot enter the recovery device 2 through the intake ring 17, so as to ensure that the air pump 5 can normally generate negative pressure in the recovery device 2 to suck in the chemotherapy solution. When the splash plate 15 is lifted by the buoyancy until the top of the connecting tube 20 at the top of the splash plate 15 is inserted into the bottom end of the suction pipe 4, the abutment rod 23 at the bottom end of the suction pipe 4 will be inserted into the connecting tube 20 to abut the trapezoidal sealing plug The plug 22 moves downward, and the airway of the connecting pipe 20 is opened at this time, so that the suction pipe 4 is connected with the connecting pipe 20, and the external air is sucked into the suction pipe 4 through the air intake ring 17, the second bellows 18, and the connecting pipe 20, so that no negative pressure is generated in the recovery device 2, and the absorption of the chemical liquid is stopped to prevent the chemical liquid in the recovery device 2 from being overloaded so that the liquid level rises to the position of the suction pipe 4 and is sucked into the air pump 5 and sprayed to the outside. Of course, a whistle 19 is also designed here. Since the whistle 19 is subjected to suction, it will make a sound, which can remind the medical staff that the liquid in the recovery device 2 is full. At this time, the medical staff can open the valve on the discharge pipe 3 to discharge the liquid in the recovery device 2 into the specified place.
