Embodiment

[0027] A medical circulating cooling syringe pump, its structure is as follows figure 1 As shown, the internal structure is as figure 2 As shown, the syringe pump is composed of a casing 1, an instrument surface 2, a single-chip microcomputer 3, a linkage disc 4, a cooling tank 5, a syringe 6, an epidural catheter 7, a push rod 8 and a motor 9. The single-chip microcomputer 3 system controls the temperature, the injection speed and the running direction of the motor 9 .

[0028] The shell 1 is in the shape of a cuboid, and the instrument surface 2 is arranged on the front end of the shell 1, on which an injection speed control panel 21, a temperature control panel 22, a speed display screen 23 and a temperature display screen 24 are arranged. The motor 9 is located under the interlocking disc 4, and the motor 9 is provided with wires for passing positive and negative currents. When energized, the motor 9 will rotate clockwise or counterclockwise, and the steering is controll...

Abstract

The invention relates to a medical circulating type cooling injection pump. The injection pump consists of a shell, an instrument panel, a motor, a single chip computer, a linkage disc, cooling grooves, an injector, a double-cavity dura mater outer conduit and push rods, wherein the shell is rectangular, the instrument panel is arranged on the front end of the shell, the motor is arranged below the instrument panel, the linkage disc is connected with the motor, the two cooling grooves are symmetrically arranged on the two sides of the instrument panel, a barrel of the injector is clamped in the cooling grooves, the rear parts of push rods of the injectors are clamped on the tail parts of the push rods, the double-cavity dura mater outer conduit is Y-shaped, two connectors on the upper endof the outer conduit are respectively connected with the front end of the injectors, and the two push rods are respectively arranged on the two sides of the linkage disc. Compared with the prior art,the invention has the advantages of strong sterility, simpleness and convenience for use, large application range and the like.

Description

technical field [0001] The invention relates to a novel medical machine, in particular to a medical circulating cooling injection pump. Background technique [0002] In the field of clinical medicine, artificial hypothermia can reduce the metabolism of tissue cells and the reduction of local blood flow. Under the low temperature state, the nervous system has a reduced response to pain, and has the effect of paralysis and analgesia. Because cooling can cause the activity of nerve cells to decrease, the cell discharge weakens and the conduction slows down, or the secretion of endogenous opioid peptides increases, causing analgesic effect. It can be used for postoperative pain treatment and long-term analgesic treatment of advanced cancer, instead of excessive use of analgesic drugs, and to prevent side effects and drug resistance caused by the use of anesthesia or analgesic drugs. At present, the analgesic treatment after surgery at home and abroad mostly adopts drug injectio...
