fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic diagram of the operation of the drug infusion of the present invention;
fig. 3 illustrates the operation steps of the drug infusion of the present invention.
In the drawings, 1. an implant; 2. a drug cavity; 3. a drug; 4. a slow release hole; 5. a porous sponge-like material; 6. injecting a needle tube; 7. and (6) guiding the tube.
Detailed Description
As shown in fig. 1 to 3, the structure for injecting a drug for releasing a drug implant, wherein a drug cavity 2 for storing a drug 3 is provided in the implant 1, the drug cavity 2 is filled with the drug 3 for treatment, a wall of the implant 1 is provided with a drug slow-release structure, which comprises slow-release holes 4 provided in the wall, and the slow-release holes 4 are filled with a porous sponge-like material 5 for controlling the slow-release speed of the drug 3; the medicine 3 in the medicine cavity 2 is released to a human body from the slow release hole 4 after permeating the porous spongy material 5; the device is also provided with a medicine injection structure which comprises an injection needle tube 6, wherein one end of the injection needle tube is a puncture end, a guide tube 7 for leading the puncture end into is arranged at the position of the slow release hole 4, and the puncture end is punctured into the porous spongy material 5 through the guide tube 7 to inject the medicine 3 into the medicine cavity 2. The medicine 3 in the implant 1 is released to a human body from the slow release holes 4 after penetrating through the porous spongy material 5, and a user can select the appropriate porous spongy material 5 according to the use conditions of different medicines to obtain different osmotic pressures for controlling the slow release speed of the medicine 3; when a medicine is required to be injected into the implant 1 which is implanted into a human body, the implant 1 and the injection needle tube 6 are imaged in the operation process by means of a medical imaging device, such as X-ray, ultrasonic wave or magnetic resonance scanning, so that the puncture end of the injection needle tube 6 can be accurately punctured into the porous spongy material 5 of the implant 1 through the slow release hole 4, then the medicine 3 is injected into the porous spongy material through the injection needle tube 6, the medicine can rapidly penetrate through the porous spongy material and be immersed into the medicine cavity 2 due to the high pressure of the injected medicine, the injection needle tube 6 is extracted after the injection operation of the medicine 3 is completed, and the whole injection process is simple and rapid.
