Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
In description of the present utility model, it will be appreciated that, term " transverse direction ", " on ", D score, " top ", " end " " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only this utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1 to Fig. 4, a kind of subcutaneous implantation doser, comprises by Teat pipette body, sealing puncture barrier film, connects hard tube and drug catheter.
By the cavity in Teat pipette body with upper end open; Sealing puncture barrier film is arranged on the top by Teat pipette body, and is sealed by the opening by Teat pipette body internal cavity upper end, adopts polysulfone resin material to make by Teat pipette body.Sealing puncture barrier film is connected with the top seal by Teat pipette body, sealing puncture barrier film with is formed by the cavity in Teat pipette body seal be subject to medicine inner chamber, sealing puncture barrier film adopts medical grade rubber to make, and is convenient to the insertion of syringe needle, makes the better tightness by medicine inner chamber simultaneously.
Be cylindrical structure by medicine inner chamber, by medicine inner chamber, there is titanium alloy pump housing inwall.Titanium alloy pump housing inwall is truncated cone-shaped structure, wherein, the diameter of titanium alloy pump housing upper inside wall cross section is large, and the diameter of lower cross section is little, the top of titanium alloy pump housing inwall is stretched into from the upper end by medicine inner chamber, and the bottom of sealing puncture barrier film is connected with the inner seal of titanium alloy pump housing upper inside wall.This titanium alloy pump housing inwall makes to have the advantage that anti-syringe needle scratches, light, good biocompatibility, pharmaceutical inert are high, and can compatible nuclear magnetic resonance, NMR.
In order to improve the advantage that the anti-syringe needle of subcutaneous implantation doser scratches, light, good biocompatibility, pharmaceutical inert are high further, and can the feature of compatible nuclear magnetic resonance, NMR, subcutaneous implantation doser also comprises by medicine inner chamber base, be arranged on the inner side bottom by Teat pipette body by medicine inner chamber base, and with by the inner side compact siro spinning technology bottom Teat pipette body; By medicine inner chamber base inner wall sealing be wrapped in outer wall by medicine inner chamber.Also be the capable structure of round platform by medicine inner chamber base, the diameter wherein by the upper cross section of medicine inner chamber base is little, and the diameter of lower cross section is large.
Connect one end of hard tube and be subject to medicine inner space, the other end connecting hard tube is communicated with drug catheter.Be enclosed with retainer ring with connecting the junction external seal of hard tube and drug catheter.Retainer ring makes the connection of conduit and the pump housing become easy, and secure bond is also more firm, and safety in utilization is more reliable, can resist high pressure and distortion.Retainer ring be connected hard tube and preferably adopt titanium alloy material to make.
In the part connecting hard tube, have two through wires holes by Teat pipette body, these two through wires holes lay respectively at the both sides by Teat pipette body axis of pitch, make subcutaneous implantation doser be positioned at subcutaneous reaching and better fix.
The use principle of the subcutaneous implantation doser that this utility model provides is:
The subcutaneous of tumor tissues is reached being embedded in by subcutaneous implantation doser by operation, then syringe needle punctures barrier film drug injection to being subject in medicine inner chamber by sealing, medicine is by connecting hard tube, tumor region is arrived again through drug catheter, thus make tumor region continuous contact to the chemotherapeutics of high concentration, embedding doser is embedded in after in human body, can according to the state of an illness can administration at any time also can for a long time between administration, chemosensitivity improves, can prevent again the infection from outside, its structure is simple and convenient.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
