Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anesthesia medical pump. Background Technology

[0002] Generally, anesthesia is considered to be a reversible functional inhibition of the central and peripheral nervous systems produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain. The Department of Anesthesiology needs to use an anesthetic pump to inject anesthetic drugs.

[0003] Chinese Patent Publication No. CN221130618U discloses an anesthesia medical pump, which includes a connecting tube with two chambers symmetrically arranged on the inner wall of the connecting tube. This anesthesia medical pump, through the arrangement of a second motor, gears, a toothed plate, a slider, a fixed rod, and a baffle, allows for the operation of the second motor via a control switch. This, in turn, drives the gears to rotate, which in turn moves the toothed plate. The cooperation of the sliding groove and the slider enhances the stability of the device. The movement of the toothed plate moves the fixed rod and the baffle, which in turn moves the push rod, dispensing the drug from the syringe at a uniform and quantitative rate. The speed of the second motor can be controlled by the control switch, thereby controlling the drug flow rate. The combination of the second motor, gears, toothed plate, slider, fixed rod, and baffle facilitates control over the flow rate and magnitude of the anesthetic drug. However, the syringe installation and fixing structure is complex, making quick syringe replacement difficult. Furthermore, the injection volume is easily inaccurate due to human error when observed by medical personnel. Therefore, this anesthesia medical pump is proposed. Utility Model Content

As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, this utility model embodiment provides an anesthesia medical pump, including an injection mechanism 1, a fixing mechanism 2, and a syringe 3. The fixing mechanism 2 is installed on the top of the injection mechanism 1, and the syringe 3 is installed inside the fixing mechanism 2.

The inner sidewall of the first housing 11 is symmetrically provided with four sliding grooves 111. The four sliders 15 are slidably connected to the inner sidewalls of the four sliding grooves 111 respectively. The internal and external threaded sleeve 14 is fixedly connected between the four sliders 15. The internal threaded collar 17 is threadedly connected to the outer sidewall of the internal and external threaded sleeve 14. Two limiting plates 171 are symmetrically fixedly connected to the outer sidewall of the internal threaded collar 17. The push plate 16 is fixedly connected to one end of the internal and external threaded sleeve 14.

[0024] The fixing mechanism 2 includes a third housing 21, a threaded hole 22, a threaded rod 23, a knob 24 and an arc plate 25. The bottom of the third housing 21 is fixedly connected to the upper surface of the first housing 11, and the syringe 3 is disposed inside the third housing 21.

[0025] In one embodiment, the motor 12 is mounted on the inner wall of the first housing 11, the lead screw 13 is fixedly connected to the output end of the motor 12, and the lead screw 13 is threadedly connected to the inner wall of the inner and outer threaded sleeve 14. With the motor 12, the motor 12 drives the lead screw 13 to rotate, and the lead screw 13 rotates in the inner and outer threaded sleeve 14, thereby driving the inner and outer threaded sleeve 14 to move.

[0026] In one embodiment, a groove 161 is provided on one side of the push plate 16; by setting the groove 161, one end of the piston handle of the syringe 3 is locked in the groove 161, which plays a role in limiting the position of the piston handle of the syringe 3.

[0027] In one embodiment, a threaded hole 22 is formed on the upper surface of the third housing 21, a threaded rod 23 is threadedly connected to the inner wall of the threaded hole 22, a knob 24 is fixedly connected to the top of the threaded rod 23, and an arc plate 25 is rotatably connected to the bottom end of the threaded rod 23 via a bearing. The arc plate 25 is slidably connected to the inner wall of the third housing 21. With the arc plate 25 in place, after the syringe 3 is placed inside the third housing 21, the knob 24 is rotated. The knob 24 drives the threaded rod 23 to rotate, and the threaded rod 23 rotates in the threaded hole 22, causing the arc plate 25 to move. The arc plate 25 squeezes the syringe 3, thereby fixing the syringe 3.

[0028] In one embodiment, the second housing 18 is fixedly connected to the lower surface of the third housing 21, and a switch 181 is installed on one side of the second housing 18; the second housing 18 is designed to facilitate gripping by the user, and the switch 181 controls the motor 12.

[0030] In operation, the present invention works as follows: First, the syringe 3 is placed in the third housing 21. Then, one end of the piston handle of the syringe 3 is engaged in the groove 161. The knob 24 is rotated, which drives the threaded rod 23 to rotate. The threaded rod 23 rotates in the threaded hole 22, which drives the arc plate 25 to move. The arc plate 25 compresses and fixes the syringe 3. Before injection, the position of the limiting plate 171 is adjusted according to the injection volume. The inner threaded collar 17 is rotated, which drives the limiting plate 171 to move. The position of the limiting plate 171 is adjusted, and the needle of the syringe 3 is inserted into the patient's injection area. Then, the motor 12 is controlled by the switch 181. Upon startup, motor 12 drives lead screw 13 to rotate. Lead screw 13 rotates within internal and external threaded sleeve 14, causing internal and external threaded sleeve 14 to move. Internal and external threaded sleeve 14 causes slider 15 to slide within slide groove 111, limiting the movement of internal and external threaded sleeve 14. Internal and external threaded sleeve 14 then drives push plate 16 to move, pushing syringe 3 piston handle to eject anesthetic solution from syringe 3 for injection into the patient. When limit plate 171 abuts against first housing 11, it indicates that the set injection volume has been reached, limiting the position of internal and external threaded sleeve 14, stopping the movement of push plate 16, turning off motor 12, and completing the injection.
