Technical Field

[0001] The present invention relates to the technical field of medical dispensing equipment, and specifically to a dispensing device and method for preventing spillage of chemotherapy drugs in oncology. Background Art

[0002] Chemotherapy drugs can enter the human body through skin mucosa, respiratory tract and other channels, and are harmful to staff in terms of carcinogenesis and organ damage. During the preparation of chemotherapy drugs, medical staff need to operate extremely carefully to avoid drug leakage.

[0003] The existing preparation of chemotherapy drugs generally relies on syringes. During the preparation process, medical staff need to pay attention to detailed operations to avoid drug spillage. For example, when extracting drugs, the syringe should not exceed three-quarters, and when extracting drugs from small vials, a small amount of air needs to be injected in advance. There are many trivial and easily overlooked details, which greatly affect the efficiency of chemotherapy drug preparation, and if the staff operate carelessly, drug solution will spill. Summary of the Invention

[0004] The technical problem of the present invention is to provide a dispensing device and method for preventing spillage, in which a socket ring is sleeved on the upper end of a chemotherapy drug bottle, and a syringe is inserted into the drug bottle through the socket ring, and can automatically absorb and store the spilled drug.

[0005] To achieve the above object, the present invention provides the following technical solution: A dispensing device for preventing spillage of chemotherapy drugs in oncology, including a socket ring. The socket ring is a cylindrical hollow tube with openings at both upper and lower ends. The lower end of the socket ring is sealed by a bottom seal and an inner rubber sleeve. The inner rubber sleeve extends into the socket ring and has an opening at the upper end. The nozzle of the chemotherapy drug bottle can be introduced into the socket ring through the upper end opening of the inner rubber sleeve. The upper end of the socket ring is provided with:

[0006] A wiping component, which includes an upper protective part. The upper protective part is inside the socket ring and is vertically above the inner rubber sleeve. The nozzle of the chemotherapy drug bottle can be tightly clamped to the bottom of the upper protective part, and the syringe needle can pass through the hollow upper protective part and be inserted into the chemotherapy drug bottle;

[0007] A leak-proof component, which is composed of multiple traction units. The traction units can expand the upper end opening of the inner rubber sleeve. In the natural state, the inner rubber sleeve has elasticity and can tightly wrap around the body of the chemotherapy drug bottle.

[0008] As a further solution of the present invention, an inner mounting plate and an elastic rubber ring are provided at the upper end of the socket ring. The inner mounting plate is located at the middle position of the upper end of the socket ring and is fixedly connected to the edge of the socket ring through multiple groups of connecting frames. The elastic rubber ring is connected between the inner mounting plate and the edge of the socket ring. The upper end of the socket ring is sealed by the elastic rubber ring and the inner mounting plate. A upper sealing plug is fixedly installed at the middle position of the inner mounting plate, and the upper sealing plug can be inserted into the syringe needle.

[0009] As a further solution of the present invention, the upper protective member is divided into a long straight tube and a circular ring member with a downward opening. The upper end of the circular ring member is fixedly connected to the lower end of the long straight tube and is communicated with the inside of the long straight tube at the upper end. The upper end of the long straight tube is fixedly connected to the lower end of the inner mounting plate. The inside of the connection part between the long straight tube and the circular ring member is filled with filling cotton. Absorbent cotton is fixedly installed on the inner wall of the circular ring member, and the absorbent cotton is located below the filling cotton. One side of the circular ring member close to the absorbent cotton is provided with an elastic inner layer.

[0010] As a further solution of the present invention, a sealing chamber is opened in the circular ring member. A sleeve is fixedly installed on one side of the upper end of the circular ring member. The upper end of the sleeve passes through the inner mounting plate and extends above the socket ring. A piston rod is slidably connected in the sleeve, and the sliding of the piston rod can input air into the sealing chamber.

[0011] As a further solution of the present invention, the traction unit includes a rotating rod, a fixed rod and a traction rope. One end of the rotating rod is rotatably connected to the inner wall of the socket ring, and the other end is rotatably connected to the fixed rod. The end of the fixed rod away from the rotating rod is fixedly connected to the upper end of the inner rubber sleeve. The lower end of the traction rope is fixedly installed at one end of the rotating rod close to the fixed rod, and the upper end is fixedly connected to the elastic rubber ring. Two groups of pull rings are symmetrically installed on the upper surface of the elastic rubber ring.

[0012] As a further solution of the present invention, an annular convex block is fixedly installed at the upper end of the inner rubber sleeve. The inner rubber sleeve is embedded in the socket ring and the upward opening gradually narrows.

[0013] As a further solution of the present invention, the traction rope is non-elastic. Both ends of the rotating rod are spherical connecting seats, and both the rotating rod and the fixed rod are lightweight rods made of rubber.

[0014] As a further solution of the present invention, a protective net is sleeved outside the filling cotton. The protective net can limit the overflow of the filling cotton and can be fixed inside the upper protective member.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the present invention, the socket ring is clamped to the upper end of the chemotherapy medicine bottle through an elastic sealing sleeve and an inner rubber sleeve. After socketing, the nozzle part of the chemotherapy medicine bottle is located above the inner rubber sleeve and clamped into the upper protective part. The user inserts a syringe needle into the upper end of the socket ring for sampling. During the sampling process, when liquid overflows, a large amount of liquid is blocked by the inner rubber sleeve and deposited at the bottom of the socket ring, without contaminating the bottle body. And a small amount of the liquid medicine contaminated on the nozzle is absorbed by the upper protective part, thus eliminating the possibility of the liquid medicine overflowing and contaminating the skin of medical staff. Moreover, during the process of preparing the liquid medicine, medical staff only need to install the socket ring and insert the syringe, and do not have to pay too much attention to the sampling details to prevent liquid overflow, thereby improving the efficiency of preparing chemotherapy drugs.

[0017] 2. During the installation and disassembly of the socket ring on the chemotherapy medicine bottle in the present invention, the inner rubber sleeve can be expanded through the traction unit, so that the socket ring can be quickly installed and disassembled, improving the disassembly and assembly efficiency, and avoiding the possibility of liquid overflow caused by violent removal and oscillation of the chemotherapy medicine bottle. And it is ensured that the overflowing liquid remains inside the socket ring to automatically collect the liquid medicine. The socket ring is a disposable product, and the liquid medicine is discarded together with the socket ring, avoiding the direct exposure of the liquid medicine to the external environment of medical waste treatment and preventing the chemotherapy liquid medicine from damaging the health of environmental sanitation workers.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a drug preparation device for preventing chemotherapy drugs from overflowing in oncology, including a socket ring 1. The socket ring 1 is a cylindrical hollow tube with openings at both the upper and lower ends. The lower end of the socket ring 1 is sealed by a bottom sealing sleeve 8 and an inner rubber sleeve 9. The inner rubber sleeve 9 extends into the socket ring 1 and has an opening at the upper end. The nozzle of the chemotherapy drug bottle can be introduced into the socket ring 1 through the upper opening of the inner rubber sleeve 9. The upper end of the socket ring 1 is provided with:

[0029] A wiping assembly, which includes an upper protective part 14. The upper protective part 14 is inside the socket ring 1 and is vertically above the inner rubber sleeve 9. The nozzle of the chemotherapy drug bottle can be tightly clamped to the bottom of the upper protective part 14, and the syringe needle can pass through the hollow upper protective part 14 and be inserted into the chemotherapy drug bottle;

[0030] A leak-proof assembly, which is composed of multiple traction units. The traction units can expand the upper opening of the inner rubber sleeve 9. In the natural state, the inner rubber sleeve 9 has elasticity and can tightly wrap around the body of the chemotherapy drug bottle.

[0031] During operation, the chemotherapy drugs are configured on a disinfection workbench. Before actually sampling the drugs, in the present invention, the socket ring 1 is clamped to the upper end of the chemotherapy medicine bottle through an elastic sealing sleeve and an inner rubber sleeve 9. After socketing, the nozzle part of the chemotherapy medicine bottle is located above the inner rubber sleeve 9 and is clamped into the upper protective part 14. The user inserts a syringe needle through the upper end of the socket ring 1 for sampling. During the sampling process, when liquid overflows, a large amount of liquid is blocked by the inner rubber sleeve 9 and accumulates at the bottom of the socket ring 1 without staining the bottle body. And a small amount of the liquid medicine stained on the nozzle is absorbed by the upper protective part 14, thus eliminating the possibility of the liquid medicine overflowing and staining the skin of medical staff. Moreover, during the process of configuring the liquid medicine, medical staff only need to install the socket ring 1 and insert the syringe, and do not have to pay excessive attention to the sampling details to prevent liquid overflow, thereby improving the efficiency of chemotherapy drug configuration. During the installation and disassembly process of the socket ring 1 on the chemotherapy medicine bottle, the inner rubber sleeve 9 can be expanded through the traction unit so that the socket ring 1 can be quickly installed and disassembled, improving the disassembly and assembly efficiency, and avoiding the possibility of liquid overflow caused by violent removal and oscillation of the chemotherapy medicine bottle. And it ensures that the overflowing liquid remains inside the socket ring 1 to automatically collect the liquid medicine. The socket ring 1 is a disposable product, and the liquid medicine is discarded together with the socket ring 1, avoiding the direct exposure of the liquid medicine to the external environment of medical waste disposal and preventing the chemotherapy liquid medicine from damaging the health of environmental sanitation workers.

[0032] As a further solution of the present invention, an inner mounting plate 4 and an elastic rubber ring 2 are provided at the upper end of the socket ring 1. The inner mounting plate 4 is located at the middle position of the upper end of the socket ring 1 and is fixedly connected to the edge of the socket ring 1 through a plurality of connecting frames 13. The elastic rubber ring 2 is connected between the inner mounting plate 4 and the edge of the socket ring 1. The upper end of the socket ring 1 is sealed through the elastic rubber ring 2 and the inner mounting plate 4. A upper sealing plug 5 is fixedly installed at the middle position of the inner mounting plate 4, and the upper sealing plug 5 can insert the syringe needle.

[0033] During operation, in the present invention, the inner mounting plate 4 is fixed to the upper end of the socket ring 1, and the upper end of the socket ring 1 is sealed through the elastic rubber ring 2 and the inner mounting plate 4 to prevent the chemotherapy drugs from overflowing from the upper end of the socket ring 1.

[0034] As a further solution of the present invention, the upper protective part 14 is divided into a long straight pipe and a circular ring part with an opening downward. The upper end of the circular ring part is fixedly connected to the lower end of the long straight pipe and is communicated with the inside of the long straight pipe at the upper end. The upper end of the long straight pipe is fixedly connected to the lower end of the inner mounting plate 4. A filling cotton 16 is filled inside the connection part of the long straight pipe and the circular ring part. An absorption cotton 17 is fixedly installed on the inner wall of the circular ring part, and the absorption cotton 17 is located below the filling cotton 16. One side of the circular ring part close to the absorption cotton 17 is provided with an elastic inner layer 18.

[0035] During operation, the nozzle of the chemotherapy medicine bottle is clamped into the circular ring part, so that the absorbent cotton 17 inside the circular ring part wraps around the surface of the nozzle of the chemotherapy medicine bottle. When chemotherapy liquid overflows and adheres to the surface of the chemotherapy medicine bottle, the absorbent cotton 17 absorbs the liquid medicine, preventing the liquid medicine from remaining on the surface of the nozzle and being contacted by medical staff after the socket ring 1 is taken out. Moreover, the filling cotton 16 blocks the bottom of the long straight pipe, restricting the liquid medicine from flowing back to the position of the upper sealing plug 5 through the upper protective part 14.

[0036] As a further solution of the present invention, a sealing chamber 19 is provided inside the circular ring part. One side of the upper end of the circular ring part is fixedly installed with a sleeve 6. The upper end of the sleeve 6 passes through the inner mounting plate 4 and extends above the socket ring 1. A piston rod 7 is slidably connected inside the sleeve 6, and the piston rod 7 can slide to input air into the sealing chamber 19.

[0037] During operation, after the nozzle of the chemotherapy medicine bottle is clamped into the upper protective part 14, medical staff can inject space into the sealing chamber 19 by moving the piston rod 7 up and down. As the gas in the sealing chamber 19 expands, the elastic inner layer 18 expands and squeezes the absorbent cotton 17, ensuring that the absorbent cotton 17 can closely adhere to the surface of the medicine bottle nozzle.

[0038] As a further solution of the present invention, the traction unit includes a rotating rod 10, a fixed rod 11 and a traction rope 12. One end of the rotating rod 10 is rotatably connected to the inner wall of the socket ring 1, and the other end is rotatably connected to the fixed rod 11. The end of the fixed rod 11 away from the rotating rod 10 is fixedly connected to the upper end of the inner rubber sleeve 9. The lower end of the traction rope 12 is fixedly installed at one end of the rotating rod 10 close to the fixed rod 11, and the upper end is fixedly connected to the elastic rubber ring 2. Two groups of pull rings 3 are symmetrically installed on the upper surface of the elastic rubber ring 2.

[0039] During operation, when installing and disassembling the socket ring of the present invention, the elastic rubber ring 2 can be pulled upward through the pull ring 3, so that the elastic rubber ring 2 pulls the traction rope 12 upward, and the rotating rod 10 is pulled through the traction rope 12, so that the rotating rod 10 rotates upward under the left and right of the traction rope 12. The rotation of the rotating rod 10 pulls the inner rubber sleeve 9 through the fixed rod 11. Through the simultaneous action of multiple groups of traction units, the upper opening of the inner rubber sleeve 9 is enlarged.

[0040] As a further solution of the present invention, an annular convex block 15 is fixedly installed at the upper end of the inner rubber sleeve 9. The inner rubber sleeve 9 is embedded in the socket ring 1 and the upward opening gradually narrows.

[0041] During operation, the annular convex block 15 makes the upper edge of the inner rubber sleeve 9 adsorb more tightly to the outer wall of the medicine bottle.

[0042] As a further solution of the present invention, the traction rope 12 is inelastic. Both ends of the rotating rod 10 are spherical connecting seats, and both the rotating rod 10 and the fixed rod 11 are lightweight rods made of rubber.

[0043] As a further solution of the present invention, the filling cotton 16 is externally sleeved with a protective net, and the protective net can limit the overflow of the filling cotton 16 and can be fixed in the upper protective member 14.

[0044] During operation, the protective net fixes the filling cotton 16 and makes it tightly agglomerated, avoiding the diffusion of the filling cotton 16 and increasing the blocking ability of the filling cotton 16 to the liquid medicine.
