Abstract
The invention relates to a medical infusion device. The medical infusion device is formed through sequentially connecting an infusion pump, a connecting hose, an infusion seat and a conduit connected with the infusion seat, wherein the infusion seat can be arranged subcutaneously, a hole is formed in the head of the conduit, and the conduit is made from silica gel and has a three-way valve design. The medical infusion device is characterized in that the infusion seat is made from porcelain containing a developing agent, the conduit is of a layered structure and comprises a developing agent layer, and ribs are arranged on the internal wall of the conduit. The infusion pump is made up of a shell and a piston located in the shell, a sealing ring is mounted on the piston, the internal cavity of the shell is partitioned into two independent spaces by the piston, the space communicating with the connecting hose is filled with medicated liquid, and sodium carbonate tablets and citric acid are placed in the space at the other side. According to the medical infusion device, when in use, CT (Computerized Tomography) and security check examination are not affected; subcutaneous puncture is convenient, and conduit blockage cannot be formed when the conduit is bent and folded.
Description
Technical field
The present invention relates to a kind of medical infusion device, belong to medical device technical field.
Background technology
In medical infusion device, development in recent years has gone out a kind of blood vessel access system of novel totally implantable, can be used forOncotherapies etc., domesticly still extensively do not carry out. It by balloon infusion pump, tube connector, can be placed in subcutaneous transfusion seat and withConnected conduit be formed by connecting in turn, wherein, balloon infusion pump is to be made up of two-layer elastic membrane, internal layer is special polyBody, skin is silica gel balloon urinary. Its operation principle is when liquid is from dosing mouth pours sacculus, and inflation, makes liquid be full of ballBody also produces malleation, and liquid shrinks the common flow velocity that determines by the elastic force of flow speed controller and silica gel balloon urinary, slow with certain speedSlowly be infused into tube connector, its feature is small-sized, light, portability, can set capacity, can be in continuous, accurate mode as patientTransfusion; Transfusion seat is made up of titanium alloy or nichrome, and conduit is generally silica gel and makes, and its cross section is circular, catheter headHave hole, and there is three-dimensional valve designs. When use, transfusion seat and conduit are all imbedded at subcutaneous, and patient's doings are not substantiallyInfluenced, can bathing and swimming, venous port access has many merits, and its advantage is except being directed to the direct administration of focusResult for the treatment of well outside, also comprise: 1. easy infection not. 2. patients ' life quality improves. 3. safeguard simple. 4. operating period limit for length. CauseThis, it is a kind of well technology.
In prior art, also there is following deficiency in above-mentioned medical infusion device: 1, transfusion seat is by titanium alloy or nichromeMake, user lives limited, as carries out CT examination, influenced by safety check etc., and 2, conduit inconvenience in the time carrying out subcutaneous puncture,3, user move in daily life, limbs bending etc. exist conduit because of bending, be folded to form plugging or tube fluid flowsNot smooth possibility, 4, balloon infusion pump provides pressure, liquid is infused into transfusion seat constantly, and and then gives through conduitMedicine, its administration pressure, along with the release of sacculus elastic force progressively reduces, can not ensure lasting and constant force value. Need to be changedEnter.
Summary of the invention
The object of the invention is, propose one and overcome above-mentioned deficiency, user is medical infusion device easily.
Technical solution of the present invention is as follows.
A kind of medical infusion device, by infusion pump, tube connector, can be placed in subcutaneous transfusion seat and the conduit that is attached thereto suitableInferior being formed by connecting, described catheter head has hole, and conduit is that silica gel is made, and it is characterized in that: described transfusion seat is by containing developmentThe porcelain of agent is made, and described conduit is layer structure, and it includes developer layer, has rib on pipe inner wall.
Owing to taking technique scheme, the present invention in use, unaffected in the time that CT, safety check check; ConduitOwing to there being developer layer, in the time carrying out subcutaneous puncture, under X-ray, can carry out easily; On pipe inner wall, have rib, bending,When folding, can not form plugging.
Further technical scheme is:
Described infusion pump is made up of housing, the piston that is positioned at housing, and sealing ring is housed on piston, and above-mentioned piston is by empty in housingChamber is divided into two separate space, wherein, in the space interlinking with tube connector, is full of liquid, in the space of opposite side, is built-in withSodium carbonate tablet and citric acid.
Owing to taking technique scheme, sodium carbonate tablet can react constantly with citric acid, discharges titanium dioxideCarbon gas, promotes piston liquid is slowly infused into tube connector with certain speed, and by subcutaneous transfusion seat and phase with itThe conduit connecting arrives affected area. Its pressure stability.
Further technical scheme is:
On described pipe inner wall, have three roots, the central angle of adjacent both sides of the chest is 1200。
Technique scheme has ensured that conduit tube fluid when bending, folding flows smooth and easy.
