Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to a portable medicine dispensing device. Background Art

[0002] Anesthesia is often used before surgery to relieve the pain of patients during surgery. Anesthesia can make people lose consciousness and has certain risks. Therefore, the dosage of anesthetics needs to be strictly controlled when dispensing anesthetics. Currently, anesthetics are usually dispensed through a dispenser.

[0003] For example, Chinese patent CN213759490U proposes a portable dispenser, including a base plate, a connecting seat, a clamping plate and a locking bolt. A mounting seat is provided on one side of the base plate, a docking groove is provided inside the mounting seat, a baffle is fixed to one end of the base plate close to the mounting seat, an injection tube is provided on one side of the baffle, a clamping seat is provided on one side of the connecting seat close to the base plate, a base is fixed to one end of the base plate away from the baffle, limit strips are provided on both side edges of the base away from the base plate, and the clamping plate is movably mounted on one side edge of the base.

[0004] However, the above patent lacks the fixation of the syringe during medication dispensing, and the syringe is easily displaced or falls off during medication dispensing. In addition, medical staff directly starts or stops dispensing by visually judging the dosage during medication dispensing, and there is a short reaction time when confirming the dosage. As a result, the final stopping time of medication dispensing is slightly earlier or later than the time of confirming the dosage, which in turn leads to inaccurate medication dosage, and the dosage needs to be repeatedly increased or decreased, which is more troublesome to operate.

[0005] Based on this, the utility model designs a portable medicine dispensing device to solve the above problems. Utility Model Content

When the quantitative retaining ring is adjusted to the required position, the fixing bolt is rotated to fix the quantitative retaining ring. At this time, the motor is started, and the motor drives the sliding push plate and the limit slider to move downward. When the limit slider moves to contact the quantitative retaining ring, it stops moving under the obstruction of the quantitative retaining ring, thereby realizing the positioning of the pulling length of the needle tube push rod, and then realizing the quantitative measurement of the medicine out of the needle tube, ensuring the accurate quantitative extraction of the medicine.

The mounting assembly 21 is arranged at the open end of the mounting cylinder 1, and is used to clamp the needle tube 4 and make the push rod of the needle tube 4 located in the mounting cylinder 1. The locking assembly 22 can fix the needle tube 4 to the mounting assembly 21.

[0034] Specifically, the mounting assembly 21 includes a mounting groove 211, a first limiting groove 212 and a giving way groove 213 which are sequentially opened on one side of the open end of the mounting cylinder 1 along the axial direction of the mounting cylinder 1, and the mounting groove 211 is located at the open end of the mounting cylinder 1, and the groove shapes of the mounting groove 211, the first limiting groove 212 and the giving way groove 213 are respectively adapted to the shapes of the needle tube 4, the baffle and the push rod.

[0035] When the needle tube 4 needs to be installed, the needle tube 4 is placed in front of the installation groove 211 and the position is adjusted so that the baffle at the lower end of the needle tube 4 is located in front of the first limit slot 212. At this time, the push rod of the needle tube 4 is located in front of the give way slot 213, and the needle tube 4 is pushed forward, so that the needle tube 4 is clamped in the installation groove 211, the baffle at the lower end of the needle tube 4 is clamped in the first limit slot 212, and the push rod of the needle tube 4 is clamped in the give way slot 213, thereby realizing the positioning clamping of the needle tube 4 and completing the installation of the needle tube 4.

[0036] Furthermore, the locking assembly 22 includes a locking slot 221 and a locking slider 222.

The two limiting sliders 322 are respectively arranged on both sides of the sliding push plate 314 and respectively slide through the outer sides of the corresponding limiting grooves 321. The quantitative retaining ring 323 can be slidably mounted on the outer side of the mounting tube 1. The quantitative retaining ring 323 is threaded with a fixing bolt 324, and one end of the fixing bolt 324 can abut against the outer wall of the mounting tube 1.

[0041] When it is necessary to extract or release the medicine, the motor 311 is started, the motor 311 drives the threaded rod 312 to rotate, the threaded rod 312 drives the threaded sleeve 313 to move up and down, the threaded sleeve 313 drives the sliding push plate 314 to move up and down under the limiting guide of the limiting slider 322 and the limiting slide groove 321, and the sliding push plate 314 drives the push rod of the needle tube 4 to move up and down through the second limiting slot 315, thereby realizing the extraction or release of the medicine, without manually pulling the needle tube 4, which is simple and convenient. When a certain amount of medicine needs to be extracted, the quantitative retaining ring 323 is rotated The quantitative retaining ring 323 moves up and down under the limit of the mounting tube 1. When the quantitative retaining ring 323 is adjusted to the required position, the fixing bolt 324 is rotated to fix the quantitative retaining ring 323. At this time, the motor 311 is started, and the motor 311 drives the sliding push plate 314 and the limiting slider 322 to move downward. When the limiting slider 322 moves to contact the quantitative retaining ring 323, it stops moving under the obstruction of the quantitative retaining ring 323, thereby realizing the positioning of the pulling length of the push rod of the needle tube 4, and then realizing the quantitative extraction of the medicine from the needle tube 4, ensuring the accurate quantitative extraction of the medicine.
