Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medicine storage structure of an insulin pump used in endocrinology department. Background Art

[0002] The medicine reservoir for insulin pump is a medical device used to store and deliver insulin. This medicine reservoir is generally made of medical-grade plastic or stainless steel, and has certain antibacterial and leak-proof properties to ensure the purity and safety of the drug. Before using the medicine reservoir, it is generally necessary to clean and disinfect it to ensure its internal cleanliness and sterility. During use, the medicine reservoir needs to be connected to the insulin pump, and the insulin is delivered to the patient's body through the drive of the pump.

[0003] The utility model with patent publication number CN219921726U in the prior art discloses a medicine reservoir for an insulin pump, which is convenient for storing insulin in a sterile and sealed manner without the need for additional extraction, thereby avoiding contamination of insulin by improper operation and ensuring that insulin does not leak during storage in the medicine reservoir, and has high stability and practicality, and has certain promotion value;

[0004] However, in the process of injecting insulin in the medicine reservoir into the insulin pump, the device determines the injection amount of insulin entirely by the medical staff observing the distance the piston moves in the medicine reservoir, and is unable to limit the injection amount. When the medical staff pushes the push rod, if they use too much force due to operating errors, excessive insulin may be injected into the insulin pump, affecting the patient's normal recovery. Therefore, a medicine reservoir structure for an endocrinology insulin pump is designed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose a drug storage structure for an insulin pump used in endocrinology department.

[0006] The technical problem to be solved by the utility model is to provide a medicine reservoir structure for an insulin pump used in endocrinology departments, which does not require the operation of extracting a quantitative amount of insulin before injecting insulin, and can quantitatively inject the insulin in the medicine reservoir body into the insulin pump to prevent excessive insulin injection. The insulin can also be sealed and stored to prevent the insulin from being contaminated, and the utility model is highly practical.

[0007] The utility model provides a medicine reservoir structure for an insulin pump for endocrinology, comprising: a medicine reservoir body, a liquid discharge joint, a piston, a push rod and a fixed plate, wherein a milliliter scale is engraved at the center of the outer surface of the medicine reservoir body, a liquid discharge joint is provided through the top of the medicine reservoir body, a piston is airtightly connected to the inner side of the medicine reservoir body, a push rod is fixedly provided at the center of the bottom surface of the piston, a fixed plate is fixedly provided at the bottom of the push rod, and a cross bar is fixedly provided laterally at the lower inner side of the medicine reservoir body;

[0008] The push rod includes an open groove, a bolt hole, a positioning bolt and a milliliter scale II. The side of the push rod is provided with an open groove, and the center of the outer surface of the push rod is provided with a plurality of bolt holes equidistantly spaced. A positioning bolt is threadedly connected to one of the bolt holes, and the outer side of the push rod is engraved with a milliliter scale II.

[0009] Preferably, the width of the opening slot is not less than the width of the cross bar, and the cross bar runs through the opening slot.

[0010] Preferably, the bolt hole passes through the open slot, and the length of the positioning bolt is equal to the diameter of the push rod.

[0011] Preferably, the drain joint includes a rubber ring, a mounting rod, a spring and a rubber disc, a rubber ring is fixedly arranged at the inner center of the drain joint, a mounting rod is installed below the rubber ring, a spring is fixedly arranged on the upper surface of the mounting rod, and a rubber disc is fixedly arranged on the top of the spring.

[0012] Preferably, the diameter of the rubber disk is larger than the diameter of the central through hole of the rubber ring, and the diameter of the rubber disk is smaller than the inner diameter of the drain joint.

[0013] Preferably, the spring passes through the central through hole of the rubber ring, and the rubber disk is located above the rubber ring.

[0014] Preferably, the spring is in a stretched state other than a maximally stretched state.

[0015] 1. The utility model stores insulin through the medicine reservoir body, and there is no need to extract the insulin required for a certain amount before injecting insulin. The positioning bolts are screwed into the corresponding bolt holes so that the positioning bolts are attached to the bottom surface of the crossbar to prevent the push rod and the piston from moving upward, and prevent insulin from being discharged from the discharge joint due to misoperation. When injecting insulin, the positioning bolts are loosened, and the distance the piston moves upward is determined according to the milliliter scale one and the milliliter scale two, and then the positioning bolts are screwed into the corresponding bolt holes so that the distance the push rod and the piston rise is limited, thereby achieving the effect of quantitatively injecting the insulin in the medicine reservoir body into the insulin pump, and preventing the occurrence of excessive insulin addition due to operational errors by medical personnel.

[0016] 2. The utility model is provided with a rubber ring and a rubber disc. Under the action of the spring elastic force, the rubber disc blocks the central through hole of the rubber ring to achieve the effect of sealing the drainage joint, and cooperates with the piston to seal the bottom of the medicine reservoir body to ensure aseptic storage of insulin. When injecting liquid, the push rod pushes the piston to move upward, and the insulin squeezes the rubber disc, so that the rubber disc is separated from the rubber ring, and the insulin is discharged from the drainage joint. The spring is in a re-stretched state and will not affect the normal injection. After the injection is completed, the elastic force of the spring causes the rubber disc to block the central through hole of the rubber ring to ensure the sealing. BRIEF DESCRIPTION OF THE DRAWINGS

A positioning bolt 403 is threadedly connected to one bolt hole 402, and a milliliter scale 2 404 is engraved on the outer side of the push rod 4.

[0028] During actual use, insulin is stored in the medicine reservoir body 1, and there is no need to extract the required amount of insulin before injecting insulin. The positioning bolt 403 is screwed into the corresponding bolt hole 402, so that the positioning bolt 403 is attached to the bottom surface of the cross bar 102, preventing the push rod 4 and the piston 3 from moving upward, and preventing insulin from being discharged from the discharge connector 2 due to misoperation. When injecting insulin, the positioning bolt 403 is loosened, and the distance the piston 3 moves upward is determined according to the milliliter scale 101 and the milliliter scale 2 404, and then the positioning bolt 403 is screwed into the corresponding bolt hole 402, so that the rising distance of the push rod 4 and the piston 3 is limited, thereby achieving the effect of quantitatively injecting the insulin in the medicine reservoir body 1 into the insulin pump, thereby preventing medical personnel from making operational errors that may cause excessive addition of insulin.
