Sealing-free tube implanted administration device

Abstract

The invention relates to a sealing-free tube implanted administration device, which comprises a pump seat, wherein a cavity is formed in the pump seat; the tail of the pump seat is provided with a passage communicated with the cavity; a conduit is arranged in the passage; a rubber mat is arranged above the cavity; the rubber mat is fixed on the pump seat through a pump cover; a protrusion is formed on the rubber mat and is close to the passage; and the protrusion is tightly attached to the port of the passage. A sleeve is arranged in the passage, a locking inner bushing is arranged between one end of the sleeve and the inner wall of the passage, the locking inner bushing is fixed through a locking cap, and the other end of the sleeve penetrates through the locking cap and is connected with the conduit. The protrusion and the rubber mat form an integrally formed structure. The device has the beneficial effects of eliminating repeated fussy operation that the tube is required to be sealed by heparin and the heparin is extracted and medicinal liquid is injected after the medicinal liquid is injected in the conventional administration device and completely avoiding harmful effects caused when the injected heparin may permeate the human body.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a tube-free implantable drug delivery device. Background technique [0002] The medical implantable drug delivery device and the widely used chemotherapy pump in the body are a multifunctional drug delivery device embedded under the skin for local perfusion of drugs or nutrition delivery. After implantation, the device can repeatedly puncture and infuse drugs , The patient can use it for a long time, and the activity and life are convenient. A large number of scientific researches and long-term clinical practice have confirmed that implanted drug delivery in vivo is the best choice for targeted therapy for tumor patients. After the device is implanted in the body, it can repeatedly infuse drugs subcutaneously, and is used for cancer-oriented chemotherapy and directional local infusion chemotherapy for preventing recurrence after tumor resection. The medicine liquid can directly enter the ...
