Detailed Description
The present invention will be described in further detail with reference to fig. 1.
Example (b): a high-precision insulin syringe, as shown in figure 1, comprises an injection needle 1 and an injection syringe 2 connected with the injection needle 1, wherein the injection syringe 2 is marked with scale marks 3 for indicating medicine dosage. The scale marks 3 comprise a plurality of long metering lines 4 with the same distance, a plurality of short metering lines 5 with the same distance and longitudinal metering connecting lines, the short metering lines 5 are positioned between the long metering lines 4, and the short metering lines 5 divide the distance between two adjacent long metering lines 4 into 5 cells. The distance between two adjacent short metering lines 5 is 1 international unit of the drug dose and the volume of 1 international unit of the drug dose is 0.01 ml. The distance between two adjacent long metering threads 4 is 5 international units of a dose of medicament. The range of the drug dose represented by the graduation mark 3 is 5-50 international units. The outer wall of the injection syringe 2 is movably sleeved with a pressurized injection cylinder 7. An injection push rod 8 is installed in the pressurized injection cylinder 7. The outer wall of the injection push rod 8 is sleeved with a pressurizing thread 9. The end of the injection push rod 8 located in the pressurized injection cylinder 7 is fixedly connected with a rubber sealing piston 10 which can be connected with the inner wall of the injection cylinder 2 in a sliding way. The end of the injection push rod 8 outside the pressurized injection cylinder 7 is fixedly connected with a rotary pressurized handle 11. The end part of the pressure injection tube 7 close to the injection tube 2 is connected with a rotary wedge scale 12 movably connected with the outer wall of the injection tube 2, and the rotary wedge scale 12 and the pressure injection tube 7 are integrally formed.
In this embodiment, the insulin pen injector is a 0.5ml standard syringe. The reading principle of the injector is as follows: the rotary wedge-shaped scale 12 is pushed forwards along the outer wall of the injection syringe 2, and 0.05ml of the rotary wedge-shaped scale advances on the scale mark 3 of the injection syringe 2 every time the rotary pressurizing handle 11 rotates one circle, so that 5 international unit doses of insulin injection are obtained. By using the principle of a micrometer screw, the scale of 0.05ml is further divided into 50 parts, and the scales of the rotary wedge scale 12 are respectively 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50, and the precision is 0.001 ml. When less than 5 international unit doses of insulin injections are to be administered, the international unit dose is obtained by simply converting the volume reading to the international unit dose, i.e., the scale value of the rotating wedge scale 12 × 0.001 (ml). The conversion formula is as follows: 0.01ml to 1 international unit dose. The syringe 2 and the pressurized syringe 7 are made of transparent sterile plastic materials. The pressurized injection cylinder 7 is connected with the outer wall of the injection cylinder 2 in a rotatable and sealed way. When insulin injection is performed on a patient, according to the injection dosage of the insulin injection prescribed by a clinician, the injection push rod 8 is driven to rotate in the pressurizing injection cylinder 7 and the injection needle cylinder 2 by rotating the rotating pressurizing handle 11, so that the insulin injection is sucked into the injection needle cylinder 2. Meanwhile, according to the scale marks 3, the international unit dose of the insulin injection to be sucked can be directly read, so that the phenomenon that the sucked insulin injection amount is inaccurate due to errors generated in the process of converting the volume of the insulin injection into the international unit dose can be avoided. By utilizing the principle of a micrometer screw gauge, the liquid volume of 0.05ml between the adjacent long metering lines 4 can be subdivided into 50 equal parts by rotating the wedge-shaped scale 12, and when insulin injections with the dose of 5 unit doses or less need to be sucked, the scales of the rotating wedge-shaped scale 12 are rotated to be overlapped with the short metering lines 5 on the injection syringe 2, so that the insulin injections with the dose of less than 5 unit doses can be sucked accurately, namely: the volume of the insulin injection solution taken is equal to the scale value of the rotating wedge ruler 12 × 0.001. After the insulin injection with accurate dose is sucked into the injection syringe 2, the injection needle 1 is penetrated into the subcutaneous tissue of the patient, the injection push rod 8 and the rubber sealing piston 10 are driven to move in the injection syringe 2 by rotating the rotary pressurizing handle 11, and the insulin injection in the injection syringe 2 is injected into the body of the patient. The international unit dose of the absorbed insulin injection can be directly read through the scale marks 3 and the rotary wedge-shaped scale 12 on the injection syringe 2, so that the process that the volume of the injection and the international unit dose need to be converted in a complex way when a common injector absorbs the insulin injection can be avoided. Simultaneously, the small international unit dose of insulin injection can be accurately sucked.
The outer wall of the syringe 2 is marked with an international unit number 13 representing the dose of medicament corresponding to the long gauge line 4.
In the present embodiment, direct reading of the unit dose of the insulin injection liquid in the injection cylinder 2 is facilitated by the international unit value 13.
The outer wall of the syringe 2 is marked with a volume reading 14 corresponding to the long metering line 4, which represents the volume of the medicament.
In the present embodiment, the reading of the volume of the insulin injection liquid in the injection cylinder 2 is facilitated by the volume reading value 14.
The length of the injection needle 1 is 12.5 mm. The diameter of the pair of needles 1 is 0.3 mm.
In the embodiment, when the insulin is injected to the patient, the force-bearing area of the punctured tissue of the patient is reduced conveniently and the injection pressure is increased through the injection needle 1 with the length of 12.5mm and the diameter of 0.3mm, so that the pain of the patient is reduced.
The side wall of the injection needle 1 is sleeved with a needle protecting sleeve 15 which is connected with the injection needle 1 in a sliding way. The side wall of the injection needle 1 is marked with a safety distance mark 16. The safety distance mark 16 is located at a distance of 5mm from the tip of the needle 1.
In this embodiment, when the patient is injected with insulin subcutaneously, the needle protecting cover 15 is slid to the safety distance mark 16, so that it is convenient to maintain the safety injection distance when the patient is injected with insulin subcutaneously. Meanwhile, when the insulin injection is required to be added into the liquid bag for use, the needle protecting sleeve 15 is slid to the bottom of the injection needle 1, so that the injection needle 1 is exposed to a sufficient length to enable the dosage of the insulin injection added into the liquid bag to be more accurate.
The outer wall of the injection syringe 2 is sleeved with a transparent rotary fixing piece 17.
In the present embodiment, when the pressurizing handle 11 is rotated, the rotation-stopping fixing of the pressurizing syringe 7 is facilitated by rotating the fixing member 17.
The tail end of the injection needle 1 is fixedly connected with a hollow fixed seat 18. The fixed seat 18 is connected with the liquid outlet end of the injection syringe 2 by screw thread.
In this embodiment, the fixation of the injection needle 1 is facilitated by the fixation seat 18. The fixed seat 18 is in threaded connection with the liquid outlet end of the injection needle cylinder 2, so that the injection needle 1 and the injection needle cylinder 2 are connected stably.
The working principle is as follows: when insulin injection is performed on a patient, according to the injection dosage of the insulin injection prescribed by a clinician, the injection push rod 8 is driven to rotate in the pressurizing injection cylinder 7 and the injection needle cylinder 2 by rotating the rotating pressurizing handle 11, so that the insulin injection is sucked into the injection needle cylinder 2. Meanwhile, according to the scale marks 3, the international unit dose of the insulin injection to be sucked can be directly read, so that the phenomenon that the sucked insulin injection amount is inaccurate due to errors generated in the process of converting the volume of the insulin injection into the international unit dose can be avoided. By rotating the wedge-shaped scale 12, a liquid volume of 0.05ml between adjacent long metering lines 4 can be subdivided into 50 equal portions, and when insulin injections of less than 5 unit doses need to be drawn, the scale of the rotating wedge-shaped scale 12 is rotated to coincide with the short metering line 5 on the injection syringe 2, thereby facilitating accurate drawing of insulin injections of less than 5 unit doses, namely: the volume of the insulin injection solution taken is equal to the scale value of the rotating wedge ruler 12 × 0.001. After the insulin injection with accurate dose is sucked into the injection syringe 2, the injection needle 1 is penetrated into the subcutaneous tissue of the patient, the injection push rod 8 and the rubber sealing piston 10 are driven to move in the injection syringe 2 by rotating the rotary pressurizing handle 11, and the insulin injection in the injection syringe 2 is injected into the body of the patient. The international unit dose of the absorbed insulin injection can be directly read through the scale marks 3 and the rotary wedge-shaped scale 12 on the injection syringe 2, so that the process that the volume of the injection and the international unit dose need to be converted in a complex way when a common injector absorbs the insulin injection can be avoided. Simultaneously, the small international unit dose of insulin injection can be accurately sucked.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
