Background technique
In traditional medical procedure, passing through artery administration, injection contrast agent, central vein nutrition, venous blood collection, anticancer
It is administered either systemically or locally, chest, abdomen drainage etc. whens, mostly use plug in duct to carry out, and this plug in duct be easy infection, behaviour
It is inconvenient to make, and reliability is low, hinders the deficiency of patient's action etc..To solve the above-mentioned problems, it is administered at present using embedding pump in vivo,
Pump housing implantation is subcutaneous, and conduit can pass through selected artery, vein or intracavitary (including abdominal cavity, thoracic cavity, pelvic cavity etc.) various approach
The specified location for reaching lesion injects medical fluid through the puncture window of the embedding pump of skin penetrating with injection needle, can repeatedly, for a long time, instead
Multiple dabbling drug, it is smaller than the toxic side effect of Formulations for systemic administration by selected approach target administration, and also local drug concentration is high, and it can be straight
It is connected to up to diseased region, strong to cancer cell lethality, the treatment curative effect of other administrations is also preferable, can avoid conventional cannula and the external world
Contact causes to infect, avoids the vascular sclerosis necrosis caused by puncturing for a long time in vein blood vessel, and patient can it is as usual movable, wash
Bath, swimming etc.；Especially during pumping vascular drug delivery by artery, artery pump-type conduit is equipped with into endovascular front end to be split
Gap type check valve makes artery catheter pump have anti-reflux in blood vessel, prevent blood back effect, after preventing artery catheter pump blood back
Embolism and lead to plugging.But there is also following disadvantages in use for the above-mentioned prior art: 1, the selection of material, processing technology
Selection, clinical application method it is improper, when use, is easy to happen the phenomenon of leakage, and causing local drug flow to enter the human body keeps skin big
Area necrosis, brings injury to patient.2, conduit is combined with the nozzle that connects of the pump housing for socket, the elastic pipe collar banding in outside, fixed
Firmness is lacking, slightly external impacts or misoperation, and there is a possibility that conduit connects nozzle with pump head separates, this is same to patient
Sample is to bring injury.3, the design of traditional structure not can guarantee the various chamber pressure requirements of clinical application.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of Internal Medicine-Oncology drug delivery devices, can control note
The flow penetrated avoids human body uncomfortable, is provided with pointed design due to leading inlet pipe, can quickly be pierced into so that administration is more stable
In vivo.
In order to achieve the above object of the invention, the technical solution adopted by the present invention are as follows:

Enter to be administered pipe end and be fixedly connected with pushing block, side is fixed with sliding slot and bearing in the delivery tube, and adaptation is slided in the sliding slot
The bull stick on the outside of sliding slot is stretched out in block, the sliding block connection, and fixation is arranged turntable on the outside of the bearing, and the bull stick other end is fixed
Turntable is connected, lower section is fixedly connected with soft stirring rod in the middle part of the turntable, and the delivery tube is outside the horizontal segment of dish-type protrusion
Heating sheet is equipped between wall and inner wall.
Further, the delivery tube other side is equipped with graduation mark.
Further, the turntable does not contact delivery tube side inner wall.
Further, the soft stirring rod bottom end connects soft paddle.
Further, the groove is equipped with card slot close to medicine outlet inner wall, and the dish-type protrusion is on medicine outlet outer wall
Fixture block equipped with adaptation card slot.
Further, the pushing block excircle packet sets rubber ring.
Further, the power supply and switch of the heating sheet that is electrically connected are equipped with above the heating sheet, the switch is located at outside delivery tube
On wall.
Further, the inner cylinder on the inside of the groove with dish-type convex inner walls are seamless connects.
Further, described to lead the pointed design of inlet pipe medicine outlet.
The invention has the benefit that
By pushing ram and pushing block in delivery tube medial movement, sliding block is mobile, drives turntable half-turn reciprocating rotation, drives
Stirring rod and paddle stirring, sufficiently make medical fluid uniform, and the drug in delivery tube is enabled to convey after heating sheet heating
To inlet pipe is led, be conducive in the recessed human body that drug can be injected smoothly, improve administration rate, graduation mark can control the stream of injection
Amount avoids human body uncomfortable, is provided with pointed design due to leading inlet pipe so that administration is more stable, can quickly be pierced into vivo, soft
The stirring rod and paddle of matter, do not influence the movement of pushing block.
