Embodiment 1

[0031] Example 1: Combining Figure 1 to Figure 7 The subcutaneous implantable drug delivery device of the present invention is described. The drug delivery device is composed of a housing 1 and a syringe pump assembly 3 arranged in the housing 1 . The casing 1 is discus-shaped, thick in the center, gradually thinner toward the periphery, and has a flat bottom. There is a suture hole 17 on both sides of the outer wall of the housing 1 for fixing the drug delivery device to the subcutaneous tissue of the human body. The housing 1 can be made of polymethyl methacrylate (PMMA resin) polymer material. The outer membrane 2 made of medical organic silica gel is hermetically coated on the outer surface of the housing 1, and since the silica gel material does not repel the body, it can reduce damage to the subcutaneous tissue of the human body.

[0032] The injection pump assembly 3 includes an injection push rod 8, an injection piston 12 connected to one end of the injection push r...

Abstract

The invention discloses a hypodermic implantation type medicine feeder, and relates to a hypodermic injector in a medical apparatus, aiming at solving the defects that a medicine bag of the existing hypodermic implantation type medicine feeder has to be injected with the medicine liquid by the medical department at a time or the existing hypodermic implantation type medicine feeder has to be withdrawn from the human body to inject the medicine after the medical liquid is used up. The hypodermic implantation type medicine feeder comprises a shell and an injection pump component arranged in the shell, wherein the injection pump component comprises an injection push rod, a liquid storage medicine bag and an injection barrel, the injection push rod is inserted into the injection barrel and can slide along with the inner wall of the injection barrel, and the liquid storage medicine bag is communicated with the injection barrel. The injection pump component further comprises at least one of medicine injection cavities communicated with the liquid storage medicine bag, each medicine injection cavity is provided with a medicine liquid injection port, and each medicine liquid injection port is arranged outside the shell. The hypodermic implantation type medicine feeder can be injected with the medicine which can be used for a long time, and the medicine feeding is manually controlled by the patient according to the use level at a time. The hypodermic implantation type medicine feeder is suitable for the cancer-curing chemotherapy feeding and the other disease which needs the internal guide feeding.

Description

technical field [0001] The invention relates to a hypodermic injection device in a medical device, in particular to a subcutaneous implanted drug delivery device. Background technique [0002] The subcutaneous implantable drug delivery device is a new type of medical device that forms a "drug channel in the human body". It is used to bury guided area drug delivery in the body, and can provide repeated channels to selected target tissues or organs for use in cancer areas. Chemotherapy, administration of drugs for analgesic treatment and treatment of other diseases, so that drugs can be directly and repeatedly delivered to target tissues or organs through the device. Compared with the conventional intravenous or intramuscular injection method, it can increase the concentration of the local tissue or organ by tens to hundreds of times, and act on the target tissue for a long time. The adverse reactions caused by it can significantly improve the therapeutic effect. [0003] Co...
