Description
Technical field
This utility model relates to field of medical device, particularly relates to a kind of Intracranial hematoma drain tube surveying cranium pressure.
Background technology
In modern medical service, Drainage of intracranial hematoma can be adopted in time when hematoma appears in intracranial, object be can within a short period of time remove hematoma, effectively alleviate the infringement of hemorrhage follow-up carbuncle in the occipital region edema and cranial nerve, and drainage complete too busy to get away drainage tube.Drainage tube is made up of elastic solid (Hookean body) silicone rubber, and this material has good biocompatibility, to tissue nonirritant, avirulence, few without anaphylaxis, body rejection; Having good physicochemical property, can keep its original elasticity and pliability, be not degraded with body fluid and contact tissue process, is a kind of inert substance of quite stable.Use drainage tube time by guid needle realize puncture, puncture or tube drawing time, guid needle insert drainage tube body in and with body before end in contact, the material of guid needle is generally titanium alloy or stainless steel material.
In the process implementing Drainage of intracranial hematoma, may cause the complication such as hydrocephalus if deal with improperly, thus cause intracranial hypertension, bring puzzlement and the pain of more diseases to patient, therefore the intracranial pressure of Real-Time Monitoring patient is absolutely necessary.Intracranial pressure many employings ICP (monitor intracranial pressure monitor), utilizes Fiber Optic Probe clinically, monitor cerebral tissue, the ventricles of the brain, subdural pressure.Monitoring intracranial pressure includes wound monitoring intracranial pressure and Noninvasive intracranial pressure monitoring, Noninvasive intracranial pressure monitoring comprises based on flash visual evoked potential and noinvasive brain electrical impedance monitoring technology etc., continuous monitoring intracranial pressure can be realized, but because they are all the intracranial pressures estimated indirectly by electrophysiological method, poor accuracy, is not employed at present clinically.Have that wound monitoring intracranial pressure comprises Intraventricular pressure measurement, Subdural space pressure measurement, epidural pressure measurement, waist wear pressure measurement, the most frequently used is that waist wears pressure measurement, but waist is worn pressure measurement and can only be reacted pressure at that time, can not monitor continuously; The method of the most accurate pressure measurement is Intraventricular pressure measurement, and by the ventricular puncture that walks abreast at sutura cranii and pupil center line point of intersection row sphenotresia, or in operation, inserting thin silica gel tube, conduit is connected with pressure tester and realizes.Therefore monitoring intracranial pressure still needs to carry out separately puncture and completes, if can carry out monitoring intracranial pressure while Drainage of intracranial hematoma, patient can be made to reduce once ailing torment, and observe conditions of patients change, early diagnosis in time.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Intracranial hematoma drain tube surveying cranium pressure, can removing hematoma while timely intracranial pressure.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: provide a kind of Intracranial hematoma drain tube surveying cranium pressure, comprise that front end is closed, the circular body of rear end opening, tubular body is provided with the different tube chamber of several pipe diameter sizes, the front end of body or front end are equipped with micro pressure sensor on the sidewall of tube chamber, are wherein installed with the wire connecting micro pressure sensor and external signal processor at least one tube chamber.
In this utility model preferred embodiment, there are the spaced apart some evagination arc strips of circumference the front side of described body, a gap is all had between every two adjacent arc strips, the length trend of string corresponding to arc strip moves towards consistent with the axis of body, each gap is all communicated with the tube chamber of caliber maximum in body, and the ratio of the maximum caliber of described tube chamber and the length of described string is 1:(3-6).The drainage effect of the drainage tube of this kind of structure is better, the length of string corresponding to arc strip is the axis projection length of arc strip, therefore the axis projection length of arc strip is much larger than the maximum caliber of tube chamber, so that gap between every two adjacent arc strips, its axial length is also much larger than the maximum caliber of tube chamber.Because of this, in drainage process, the clot of intracranial is difficult to block described gap, and the clot that intracranial produces can realize with arriving with row, and the promptness of clot discharge is better, so that the drainage tube drain of this kind of structure is unobstructed, drainage effect is better.
In this utility model preferred embodiment, the quantity of described arc strip is three or four.Like this, simply and rationally, the respective strengths of its axis is better for the drainage tube of said structure.
In this utility model preferred embodiment, the front side circumference of body arranges some spaced apart apertures, and the maximum caliber of body and the ratio of hole diameter are (2-4): 1.The drainage tube structure of this kind of structure is simple, be easy to processing, cost is low.
In this utility model preferred embodiment, the material of described body is medical grade elastic solid (Hookean body) silicone rubber or medical grade PVC.This material has good biocompatibility, physicochemical property, and can keep its original elasticity and pliability with body fluid and contact tissue process, elastic restoring force is good.
The beneficial effects of the utility model are: this utility model structure is simple, drainage effect is better, by installing micro pressure sensor additional in drainage tube front end, can while removing hematoma intracranial pressure timely and accurately, prevent in advance to occur the complication such as intracranial hypertension in drainage, and reduce the pain of patient's ventricular puncture, be suitable for applying.
