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 is a kind of embedding subcutaneous with widely used body embedded set chemotherapy pump nowadays; Be used for regional perfusion's medicine or carry the multi-functional doser of nutrition; But repeated localised puncture dabbling drug after this device is implanted, but patient's life-time service, activity, life are conveniently.Confirm that through a large amount of scientific researches and secular clinical practice body embedded set drug delivery implant is the optimum selection to the tumor patient targeted therapy.Can be after this device implants repeatedly through subcutaneous directional perfusion medicine, be used for the directionality regional perfusion property chemotherapy of prevention of recurrence behind cancer guidance quality chemotherapy and the tumor resection.Medicinal liquid can directly get into specified location through Teat pipette and conduit, and the concentration of diseased region topical remedy is increased greatly, has improved lethality and curative effect to cancerous cell.Alleviate the toxic and side effects of chemotherapy, can effectively control the state of an illness, prolong patient's life, improved patient's quality of life.
Existing doser needs use heparin in sealing after injecting liquid drug finishes, in case hemostasis liquid refluxes, in the process with heparin in sealing, because the unavoidable carelessness of operator, heparin can occur and use too much, excessive etc. and infiltration human body generation harmful effect; The trouble sense that repetition troublesome operation that operator face produces is all unfavorable to patient, therefore is badly in need of a kind of new medical apparatus and instruments addressing the above problem, and overcomes the above-mentioned deficiency that present prior art exists.
Summary of the invention
The purpose of this invention is to provide a kind of tube sealing implantable drug delivery system of exempting from; Solve existing doser and after injecting liquid drug finishes, all need use heparin in sealing; Heparin is extracted the repetition troublesome operation of injecting medicinal liquid out, and has avoided fully possibly can infiltrating human body and bring harmful effect by heparin after the injection.
The objective of the invention is to realize through following technical scheme:
A kind of tube sealing implantable drug delivery system of exempting from comprises pump seat, and said pump seat inside is provided with cavity; The afterbody of pump seat is provided with the passage that is communicated with cavity; Be provided with conduit in the passage, the top of said cavity is provided with rubber cushion, and rubber cushion is fixed on the said pump seat through pump cover; Be provided with projection near described passage place on the rubber cushion, projection is close on the port of passage; The inside of said passage is provided with sleeve pipe, is provided with cover in the locking between the inwall of sleeve pipe one end and passage, and cover is fixed through locking cap in the locking, and the telescopic other end passes locking cap and is connected with conduit.
Preferably, said projection and the rubber cushion structure that is formed in one.
Beneficial effect of the present invention is: solve existing doser and after injecting liquid drug finishes, all need use heparin in sealing, heparin to extract the repetition troublesome operation of injecting medicinal liquid out, and avoided the injection postheparin to infiltrate human body fully and bring harmful effect.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the described structural representation of exempting from the tube sealing implantable drug delivery system of the embodiment of the invention;
Fig. 2 is the described cutaway view of exempting from the tube sealing implantable drug delivery system of the embodiment of the invention;
Fig. 3 is the described decomposition texture sketch map of exempting from the tube sealing implantable drug delivery system of the embodiment of the invention.
Among the figure:
1, pump seat; 2, cavity; 3, passage; 4, sleeve pipe; 5, cover in the locking; 6, locking cap; 7, conduit; 8, rubber cushion; 9, pump cover; 10, projection.
The specific embodiment
Shown in Fig. 1-3, the described a kind of tube sealing implantable drug delivery system of exempting from of the embodiment of the invention comprises pump seat 1; Said pump seat 1 inside is provided with cavity 2, and the afterbody of pump seat 1 is provided with the passage 3 that is communicated with cavity 2, and the inside of passage 3 is provided with sleeve pipe 4; Be provided with cover 5 in the locking between the inwall of sleeve pipe 4 one ends and passage 3, cover 5 is fixing through locking cap 6 in the locking, and the other end of sleeve pipe 4 passes locking cap 6 and is connected with conduit 7; The top of said cavity 2 is provided with rubber cushion 8, and rubber cushion 8 is fixed on the said pump seat 1 through pump cover 9, is provided with projection 10 near described passage 3 places on the rubber cushion 8; 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 the described cavity 2, along with the increase of the injection that injects; Pressure in the cavity 2 increases; When pressure surpassed 150kPa, rubber cushion 8 produced distortion and outwards arches upward, and projection 10 is separated with the port of passage 3; In the injection admission passage 3, reach assigned address through conduit 7; When injection finished, cavity 2 inner pressure can reduce, when pressure is lower than 150kPa; Rubber cushion 8 recovers initial condition, and projection 10 is close to the port of passage 3, with cutting off fully between cavity 2 and the conduit 7; The intermediate formation negative pressure state; Therefore backflow phenomenon can not take place, prevent that effectively liquid medicine injection from finishing after, blood of human body forms thrombosis and stops up conduit and make it this apparatus and lost efficacy because of 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 on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within protection scope of the present invention.
