Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a precise lifting device for a needle-inserting medicine transfer device. Background Art

[0002] In hospitals, in order to give intravenous drips and injections, the medicine needs to be dissolved in saline and then injected into the human body, which requires the use of a drug dissolver. The drug dissolver generally uses a syringe to directly absorb the medicine, mixes the medicine according to a certain ratio, and then injects the mixed medicine into the human body. However, it is difficult to ensure the accuracy of the medicine metering of this kind of manual suction injection. Therefore, an automatic drug delivery device with automatic drug delivery and mixing is used to accurately and strictly control the injection volume of the medicine. However, the needle drug delivery device needs to absorb the medicine in the medicine for mixing, so the needle head of the drug delivery device needs to be inserted into the medicine bottle, and the medicine is transported through the pipeline through needle suction. However, when the needle head is manually inserted, it is difficult to accurately insert the needle head into the bottom of the bottle, which will cause the medicine to be unable to be completely sucked in and used completely, resulting in a certain amount of waste. If the insertion force is too large, the liquid inlet at the bottom of the needle will be bent, causing damage to the needle, or the bottom of the bottle will be punctured, affecting normal use. Therefore, it is necessary to use an automated lifting device to automatically control the needle so as to accurately insert the needle.

[0003] The existing precise lifting device for needle-insertion medicine transfer devices adopts an electric-controlled slide rail and a slider to quickly lift and lower the entire device. However, there is no limit structure between the electric slide rail and the slider, and the slider is completely controlled by computer commands. When the slider slides, due to inertia or external factors, such as a large amount of dust or liquid on the slide rail, the slider may move slightly too far, resulting in a deviation in the command control, causing the needle to be over-inserted or not fully inserted. The accuracy of the device will be affected by many external conditions, resulting in low accuracy and inaccurate use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a precise lifting device for a needle-inserting medicine transfer device is proposed. Utility Model Content

[0023] By adopting the above technical solution, the electric control guide rail 3 and the electric slider 4 can effectively drive the needle head 11 of the drug delivery device to perform lifting work;

[0024] The limit mechanism 7 is used to limit the downward position of the electric slider 4, so that the electric slider 4 can accurately perform the lifting work, avoiding the movement deviation of the electric slider 4, resulting in the needle head 11 of the drug delivery device not being fully inserted into the bottom of the medicine bottle or the insertion depth being too large, causing the head to bend;

[0025] The locking mechanism 8 can be used to lock the limiting mechanism 7, so that the adjustment position of the hand wheel 704 is fixed, and the screw rod 701 is prevented from rotating twice, which causes the limiting position of the blocking plate 702 to shift.

[0026] Furthermore, the limiting mechanism 7 includes a screw rod 701 rotatably arranged at the bottom end of the inner surface of the through cavity 6 , a hand wheel 704 is fixedly arranged at the upper end of the screw rod 701 passing through the through cavity 6 , and a blocking plate 702 is threadedly connected to the surface of the screw rod 701 .

[0028] Furthermore, the limiting mechanism 7 also includes a pointer 703 fixedly installed on the right side of the front end of the surface of the blocking plate 702, and the rear end of the blocking plate 702 is slidably arranged on the inner surface of the through cavity 6, and the front end protrudes from the through cavity 6. The pointer 703 is installed at the edge position of the front end of the blocking plate 702 protruding from the through cavity 6, and the pointer 703 points to the side of the scale line 5.

[0029] By adopting the above technical solution, the blocking plate 702 utilizes the position limiting of the through cavity 6, and can stably move up and down when the screw rod 701 rotates, avoiding rotating with the screw rod 701;

[0030] The pointer 703 moves along with the blocking plate 702 and points to the scale line 5 . The pointer is used to accurately adjust the position of the blocking plate 702 and limit the electric slider 4 by pointing to the height position marked by the scale line 5 .

[0031] Furthermore, the locking mechanism 8 includes positioning grooves 801 evenly distributed around the position where the screw rod 701 passes through the upper end of the surface of the base 1, and a latch 802 is slidably inserted inside the positioning groove 801, and the upper end of the latch 802 slides through the hand wheel 704.

[0032] By adopting the above technical solution, the positioning groove 801 limits the lower end of the latch 802, and the upper end of the latch 802 is penetrated by a hand wheel 704, so that the adjustment position of the hand wheel 704 is fixed.

[0033] Furthermore, the locking mechanism 8 also includes a fixing plate 803 fixedly installed on the surface of the latch 802 below the hand wheel 704 , a spring 804 is fixedly installed above the surface of the fixing plate 803 , and the upper end of the spring 804 is fixedly connected to the hand wheel 704 .

[0035] Furthermore, a connecting plate 9 is fixedly installed on the front side of the surface of the electric slider 4 , an adjusting plate 10 is arranged below the connecting plate 9 , and a medicine transfer device needle head 11 is fixedly arranged at the front end of the adjusting plate 10 .

[0036] By adopting the above technical solution, the needle 11 of the drug delivery device can effectively pierce the bottle mouth sealing membrane using the needle tip.

[0041] Working principle: When using the precise lifting device of the needle medicine delivery device, first, pull the pin 802 out of the positioning groove 801, then adjust the limit mechanism 7 according to the puncture depth of the medicine bottle, turn the hand wheel 704, drive the screw rod 701 to rotate, and then adjust the blocking plate 702 up and down under the limit of the blocking plate 702 by the through cavity 6 and drive the pointer 703 to move, according to the position of the pointer 703 pointing to the scale line 5, the blocking plate 702 is accurately adjusted up and down. After the height position adjustment is completed, the pin 802 will be inserted into the nearest corresponding positioning groove 801 under the transmission thrust of the spring 804 through the fixed plate 803, so that the positioning groove 801 limits the lower end of the pin 802, and the upper end of the pin 802 There is a hand wheel 704 that passes through it, so that the hand wheel 704 can be adjusted to a fixed position to avoid the second rotation of the screw rod 701, which causes the blocking plate 702 to shift in the limit position. Then the electric control guide rail 3 and the electric slider 4 can be started, and the connecting plate 9 can use the screw rod 13 to drive the adjustment plate 10 to move, so that the needle head 11 of the medicine transmitter moves down to puncture the medicine bottle until the electric slider 4 moves down to the limit position of the blocking plate 702 and stops. After the puncture is completed, if there is a slight error, the drive motor 12 can be used to drive the screw rod 13 to rotate. Under the limit of the guide rod 14, the adjustment plate 10 can be moved up and down alone to further finely adjust the position of the needle head 11 of the medicine transmitter. This is the working principle of the precise lifting device of the needle medicine transmitter.
