Description
Technical Field
The utility model relates to a brain device field of dosing especially relates to a novel brain is dosed device.
Background
Due to the presence of the blood-brain barrier, most of the material cannot reach the cranium. Even if the target substance is injected through the abdominal cavity or the blood vessel, the target substance enters the cranium through the circulation of body fluid. However, most drugs are metabolized during this process. That is, the substance that enters the cranium in this way is not the drug we originally injected, but a metabolite of the substance. Secondly, this mode of administration helps to improve the efficiency of use of drugs, particularly high value and self-extracting drugs. The quantity of the medicine injected into the abdominal cavity is higher than that of the medicine injected into the craniocerebra by dozens of times. Therefore, when the medicine is limited, the craniocerebral administration can greatly reduce the medicine loss.
Furthermore, when continuous administration is needed, the existing craniocerebral injection administration mode has low efficiency, multiple injections are needed, great psychological burden and economic burden are brought to patients, and in order to provide invasive administration, the workload of medical staff is increased by increasing infection risks, so that how to develop a novel brain administration device becomes a problem to be solved urgently by technical staff in the field.

In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model relates to a novel brain drug delivery device, which comprises a drug bag sleeve, a base and a transfusion tube, wherein the upper surface of the base is provided with a drug delivery cavity, the lower surface of the drug bag sleeve is provided with a drug loading cavity matched with the base, and the drug loading cavity and the drug delivery cavity form a drug bag; the side of the base is provided with an output tube, the output tube is connected with the infusion tube, the far end of the infusion tube is a blind end, and a plurality of infusion holes are formed in the circumferential surface of the far end of the infusion tube.
Furthermore, the vertical section of the medicine bag sleeve is trapezoidal, and a groove is formed in the top end of the medicine bag sleeve.
Further, the medicine bag sleeve is made of medical silica gel.
Furthermore, a nylon mesh is arranged on the outer surface of the medicine bag sleeve.
Further, the base specifically adopts the polyethylene material, the output tube with base integrated into one piece.
Furthermore, the output tube is provided with a connector and is detachably connected with the near end of the infusion tube through the connector.
Further, the transfer line specifically adopts medical silica gel material.
Furthermore, the cross sections of the medicine bag sleeve and the base are circular.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the utility model discloses the brain device of dosing is as a long-term device of dosing, be used for treating some refractory diseases and old disease, the anther sac that constitutes the medicine feeding chamber of anther sac cover and the lower medicine chamber of base is placed in the brain cortex through the operation, with the transfer line through the probe send to pathological change position, regularly get into the anther sac through injecting the medicine, the medicine reachs pathological change department through the transfer line, the obstructed blood brain barrier that passes through, the medicine is effectual fast, high concentration, various troubles that the repeated operation brought have also been avoided simultaneously. The utility model discloses the brain device of dosing simple structure, the function is practical, has replaced the current operation of dosing of having an wound, has reduced the damage to the brain tissue, has reduced the exogenous infection risk, improves brain tissue absorption rate, has improved treatment, has shortened patient's cure time, has reduced the medical expense, has improved patient's quality of life.
