In order to achieve the above objectives, the patient-controlled, analgesic pumping structure of the present invention transmits a liquid anesthetic power to receive power. The patient's self-controlled analgesic pump structure consists of a pump body, a lining, and a conductive material. The pumping system has a liquid phase, the infusion part has an infusion channel, an infusion and a 'night exit', and the anesthetic is transported by the wheel liquid inlet and the infusion channel to the delivery system and the pump body side is sealed. To accommodate the anesthetic, pump 4 body. The electrically conductive material is on the Lai-side, and the electrically conductive material receives power from the power source to cause deformation. Among them, the deformation of the conductive material is combined with the force to drive the deformation of the membrane body, the membrane body is filled in the body of the pumping county, and the body of the immersion body (10) forms a pressure difference, thereby providing an anesthetic to flow from a high pressure to a low pressure. The conductive material is one of a piezoelectric conductive material, an electrostatic conductive material, and a metal composite conductive material. The patient-controlled analgesic pump has a structure--the first one-way wide--the second one-way valve' the first-way valve and the second one-way valve are located on the infusion part, and the first-one-way provides an anesthetic agent The one-way transmission of the sluice channel flows to the infusion outlet. The second one-way provides an anesthetic that flows from the infusion population to the infusion channel in one direction. When the middle material receives the power of the $ source, when the negative voltage rises to a positive voltage, the electric material is deformed and bent in the - direction, and when the positive voltage drops to a negative voltage, the conductive material is bent in the direction of the ~ to transmit the anesthetic. When the conductive material receives the power of the power supply, when the voltage output is increased from the low frequency to the frequency, the number of rounds of the anesthetic is increased; when the voltage output is reduced from the high frequency to the low frequency, the number of rounds of the anesthetic is reduced. The structure of the patient-controlled analgesic pump according to the present invention has one or more of the following advantages: (1) Pushing the pump by the deformed conductive material instead of the conventional motor to promote the flow of the liquid for the anesthetic By rotating the wheel to the human body, it can reduce the volume of the traditional motor household to the pump, greatly reduce the cost of the flower, and reduce the power consumption. (2) When the power of the power source is received by the conductive material, the conductive material is bent (4) when it is raised, and the bending curvature of the low material is reduced to increase the output of the intoxicating agent. Also, _ lose _ increase the anesthesia (four), and the number of times the coffee is thin, and the dose per infusion can be stably controlled. (3) With the patient's self-mapping structure, there is a concern that the pumping machine H has contamination problems in recycling. As for the detailed structure of the creation, the principle and the effect of the creation, the complete understanding can be achieved by referring to the following description of the M408370. [Embodiment] Please refer to Fig. 1 and Fig. 2, which are schematic diagrams showing the three-dimensional structure of the patient-controlled analgesic pump in the first embodiment of the present invention and the structural decomposition of the patient's self-controlled analgesic pump. The patient-controlled pain-relieving Lipu, the micro-pump technology can be used to create a disposable patient-controlled device (Patient-Controlled Armlge Sia, PCA). In the figure, the structure 1 of the patient-controlled analgesic pump transmits the liquid anesthetic agent 2 and receives the power of the power source 3. The patient-controlled analgesic pumping structure 1 comprises a pump body u, a body 12, a conductive material 13, a first one-way valve 14 and a second one-way weir as needed. The pump body 11 has an infusion portion U1. The infusion portion (1) has an infusion channel 1111, an infusion port 1112, and an infusion port 1113. The anesthetic agent 2 is delivered from the infusion port 1112 and the infusion channel to the infusion port 1113. The membrane body 12 is located on the side of the pump body u, and can be coated and connected to one side of the fruiting body 11 side, the infusion unit 111 side or the side of the infusion channel 11U for sealing the pump body 11 side. Forming the pump body U' having the membrane body 12 to accommodate the storage of the anesthetic agent 2 in the pump body u, preventing the anesthetic agent 2 7 M408370 from flowing, and deforming the subsequent conductive material 13 to cause the membrane body 12 to deform. . The film body 12 can be a metal material, a plastic material or a rubber. The conductive material 13 can be attached to the side of the film body 12, the conductive material 13 receives the power of the power source 3 to generate deformation, or the conductive material 13 is applied to the side of the conductive material 13 near the side of the body 12, and the film body is applied after the force is applied. 12 with deformation. The first check valve 14 and the second check valve 15 are respectively located on the infusion portion (1). The first check valve 14 provides the anesthetic agent 2 and is unidirectionally transmitted from the infusion channel mi to the infusion solution π 1113 1 two-way valve 15 An anesthetic agent 2 is provided and is unidirectionally delivered from the infusion port 1112 to the infusion channel mi.凊 Refer to Figures 3a to 3c, and continue to refer to Figure j and Figure 2, which is the structural section of the patient-controlled analgesic pump of the first embodiment: __, the first-actuation diagram and the second actuation diagram . The U-shaped deformation of the conductive material causes the deformation of the membrane body 12, and the membrane body 12 is pressed against the anesthetic agent 2 in the pump body U (as shown in Fig. 1), so that a pressure difference is formed between the inside and the outside of the pump body U. The anesthetic agent 2 is provided to be displaced from a high pressure to a low pressure. When the 1 'electric material 13 receives the power of the power source 3, when the negative voltage rises to a positive voltage, the 'the electric material 13 deforms toward the - direction f'. When the positive voltage drops to a negative voltage, the conductive material 13 is deformed and bent toward the other direction, and the conductive material is bent. 13 is used to pressurize the membrane body 12 to deform the membrane body 12, thereby promoting the transmission of the anesthetic agent 2. Therefore, if the pressure in the body u is higher than that of the poly-pump body 11 and the pressure opens the first check valve 14, the anesthetic agent 2 flows from the infusion channel 1111 to the infusion π 1113 (eg, 3b _ Show). If the pressure in the pump body 11 is lower than the Lipu body n, the pressure opens the second one-way room 15 ', then the anesthetic agent 2 is transported by the infusion population 1112 to the infusion channel U11 (as shown in Fig. 3c). The above-mentioned conductive material 13 may be a piezoelectric conductive material (such as No. % to the figure), an electrostatic conductive material (as shown in Fig. 4) or a metal composite conductive material (not shown in Fig. 5). The wiper 'piezoelectric conductive material is a paste against the voltage effect, and the externally applied electricity repeatedly produces a bending deformation. The electrostatic conductive material has a capacitance c which sequentially drives the electrostatic conductive material by suction and repulsive force between the charges to cause deformation. Further, the metal composite conductive material has at least -Wei, which converts the electric power of the conductive material 13 into thermal energy, and the thermal expansion coefficient of each material of the metal composite conductive material is different to cause bending deformation. This embodiment is represented by an ionic polymer metal composite conductive material, but is not limited thereto. The patient-controlled self-controlled anesthesia pump 1 is a disposable patient-controlled analgesic pump because of its low price, independent pumping, and small volume that does not require contamination of the pump. M408370 Where the conductive material 13 receives the power of the power source 3 (as shown in Fig. 1), when the low voltage high voltage material material 13 material increases, when the high clock falls to a low level, the bending curvature of the conductive material 13 decreases, thereby increasing Reduce the output of narcotics 2. When the conductive material 13 receives the power of the power source 3, the output of the anesthetic agent 2 is increased when the voltage output is raised from the low frequency to the high frequency; and the output of the anesthetic agent 2 is decreased when the Wei output is reduced from the frequency to the low frequency. Please refer to Fig. 6, the structure of the patient-controlled pain-relieving pump of the fourth embodiment of the present invention. In the figure, the pump body further comprises a liquid reservoir 112, and the liquid storage unit 112 is connected to the infusion solution 12 to provide the pump body itself to supply the anesthetic agent 2 without external anesthetic. It is supplied to the pump body 11. Referring to Figure 7, it is a schematic cross-sectional view of the patient-controlled analgesic pump of the fifth embodiment of the present invention. In the figure, the infusion population 1112 and the infusion outlet 1113 are located at one end of the pump body 11 and at the other end of the pump body 11. One end of the wheel liquid inlet 1112 and the other end of the infusion outlet m3 may be located at the same side of the same side, or may be one end and the other end of the different sides (as shown in Fig. 2 and 1V1HU«J70 shown in the figure). ‘As mentioned above, the effectiveness of this case can indeed improve the shortcomings of the unsuccessful practices of the practitioners’ and the creations have not been used publicly. In line with the requirements of patents, Newfa has proposed a new type of patent application. Please grant a patent, which is a prayer.
