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
The present invention relates to a kind of medical apparatus, relate in particular to a kind of tube sealing implantable drug delivery system of exempting from.
Background technology
Medical vivo implantation type doser and nowadays widely used body embedded set chemotherapy pump are a kind of embedding subcutaneous, multi-functional doser for regional perfusion's medicine or conveying nutrition, this device can repeated localised puncture dabbling drug after implanting, and patient can life-time service, movable, life is convenient.Through a large amount of scientific researches and long-term clinical practice, confirm, body embedded set drug delivery implant is the optimum selection for tumor patient targeted therapy.Can be repeatedly through subcutaneous directional perfusion medicine, for the directionality regional perfusion property chemotherapy of prevention of recurrence after cancer guidance quality chemotherapy and tumor resection after this device implants.Medicinal liquid can directly enter specified location through Teat pipette and conduit, and the concentration of diseased region topical remedy is increased greatly, has improved the lethality of cancerous cell and curative effect.Alleviate the toxic and side effects of chemotherapy, can effectively control the state of an illness, extend patient's life, improved patient's quality of life.
Existing doser needs with heparin in sealing after injecting liquid drug, in case Hemostatic Oral Liquid refluxes, with in the process of heparin in sealing, due to the unavoidable carelessness of operator, there will be heparin to use too much, excessive etc. and infiltrates human body and produce harmful effect; The trouble sense that the repetition troublesome operation that operator face produces is all unfavorable to patient, is therefore badly in need of a kind of new medical apparatus and instruments to address the above problem, and overcomes currently available technology above shortcomings.
Summary of the invention
The object of this invention is to provide a kind of tube sealing implantable drug delivery system of exempting from, solve existing doser all needs with heparin in sealing after injecting liquid drug, heparin is extracted the repetition troublesome operation of injecting medicinal liquid out, and has avoided may can infiltrating human body and bring harmful effect by heparin after injection completely.
The object of the invention is to be achieved through the following technical solutions:
A kind of tube sealing implantable drug delivery system of exempting from, comprise pump seat, described pump seat inside is provided with cavity, the afterbody of pump seat is provided with the passage being communicated with cavity, in passage, be provided with conduit, the top of described cavity is provided with rubber cushion, and rubber cushion is fixed on described pump seat by pump cover, on rubber cushion, near described passage place, be provided with projection, projection is close on the port of passage; The inside of described passage is provided with sleeve pipe, between sleeve pipe one end and the inwall of passage, is provided with locking inner sleeve, and locking inner sleeve is fixed by locking cap, and the other end of sleeve pipe is connected with conduit through locking cap.
Preferably, described projection and the rubber cushion structure that is formed in one.
Beneficial effect of the present invention is: solve existing doser all needs to extract with heparin in sealing, heparin the repetition troublesome operation of injecting medicinal liquid out after injecting liquid drug, and has avoided injection postheparin to infiltrate human body completely and bring harmful effect.

The specific embodiment
As Figure 1-3, a kind of tube sealing implantable drug delivery system of exempting from described in the embodiment of the present invention, comprise pump seat 1, described pump seat 1 inside is provided with cavity 2, the afterbody of pump seat 1 is provided with the passage 3 being communicated with cavity 2, the inside of passage 3 is provided with sleeve pipe 4, between sleeve pipe 4 one end and the inwall of passage 3, be provided with locking inner sleeve 5, locking inner sleeve 5 is fixing by locking cap 6, the other end of sleeve pipe 4 is connected with conduit 7 through locking cap 6, the top of described cavity 2 is provided with rubber cushion 8, rubber cushion 8 is fixed on described pump seat 1 by pump cover 9, on rubber cushion 8, near described passage 3 places, be provided with projection 10, projection 10 and rubber cushion 8 structure that is formed in one, projection 10 is close on the port of passage 3.
During work, injection device injects injection in described cavity 2, increase along with the injection injecting, pressure in cavity 2 increases, when pressure surpasses 150kPa, rubber cushion 8 produces distortion and outwards arches upward, and projection 10 is separated with the port of passage 3, in injection admission passage 3, by conduit 7, reach assigned address; When injection is complete, the pressure of cavity 2 inside can reduce, when pressure is during lower than 150kPa, rubber cushion 8 recovers initial condition, and projection 10 is close to the port of passage 3, will between cavity 2 and conduit 7, cut off completely, intermediate formation negative pressure state, therefore backflow phenomenon can not occur, after effectively preventing liquid medicine injection, blood of human body forms thrombosis obstruction conduit and makes it this apparatus inefficacy because refluxing.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
