Abstract
The utility model relates to an intracranial pressure detecting device which passes a lumbar spinal epidural outer cavity (epidural outer cavity). The utility model is composed of a micro guiding tube, a cover tube, a liquid pumping device, a liquid filling device and a physiological pressure sensor which are connected. The front end of the micro guiding tube forms a film balloon. Compared with intracranial pressure monitors existing in China and out of China, the utility model has the advantages of simple structure, low cost, sensitive and accurate pressure transmission, long monitoring time, convenient and simple operation, small trauma of patients, no need of craniotomy and difficult infection occurrence. The utility model opens a new way for monitoring intracranial pressure.
Description
This utility model relates to a kind of intracranial pressure sniffer.
Because numerous disease all can cause the change of intracranial pressure in the human body, therefore the same with electrocardio, blood pressure, body temperature and breathing, the human body intracranial pressure is a MAIN OUTCOME MEASURES on the clinical medicine, monitoring to intracranial pressure not only is used for medical diagnosis on disease, and for patient's complete observation, treatment is instructed in drug screening, judging prognosis and all very important for critical patient's rescue etc.At present, the monitoring of intracranial pressure is mainly used in neural inside and outside section, Anesthesia Department, department of pediatrics, contagious department and internal medicine, is one of main monitoring means of clinical critical patient.At present the intracrenial pressure monitor that uses is that a pressure transducer is put into exterior dura or Intraventricular, the intracranial pressure signal of experiencing on the pick off, spread out of on the monitoring instrument from electric lead or optical fiber show again, record etc.This method requires to hole on skull, and it is painful big with patient to perform a surgical operation, and complicated operation requires patient not move after the operation, and therefore easy infection still can not be extensive use of on one's body the critical patient.Another kind method is with conduit that human body cerebrospinal fluid lead body is outer and be connected to monitoring again on the pressure transducer, and this method is dangerous, easy infection, and leakage and bring out cerebral hernia easily, user is had a lingering fear.Owing to there is above-mentioned shortcoming, ICP only has senior hospital to use at home, still can not extensively promote.
The purpose of this utility model be to provide a kind of simple in structure, cost is low, pressure transmit sensitive, pressure testing method is simple, the result is accurately through stiffness of the waist spinal meninges exocoel (cerebral dura mater exocoel) intracranial pressure sniffer.
The technical solution of the utility model is as follows: it is by microtubular, trocar sheath is taken out, charging device and physiological pressure transducer four parts constitute, and is provided with a thin film sacculus that fuses with it at the front end of microtubular, microtubular is with a trocar sheath outward, and the rear end of microtubular links to each other with tee T; A branched pipe connection of tee T is taken out, charging device, and another branched pipe is connected with physiological pressure transducer; Microtubular (comprising sacculus) is taken out the loop that charging device and physiological pressure transducer are connected to form sealing, has been full of the liquid of sealing therebetween.
This utility model is compared with existing domestic and international intracrenial pressure monitor, have simple in structure, cost is low, pressure transmits sensitive and accurate, monitoring time is long, simple to operation, patient trauma is little, does not need operation of opening cranium, is difficult for taking place the advantage of infection, opened up a new way of ICP, can be in the rapid wide popularization and application of hospitals at different levels.
Fig. 1 is this utility model structural representation.
As shown in the figure: this utility model is by microtubular 1, trocar sheath 2, taking out charging device 6 and physiological pressure transducer 3 four parts constitutes, front end at microtubular 1 is provided with a thin film sacculus 4 that fuses with it, trocar sheath 2 is enclosed within outside the microtubular 1, sacculus 4, microtubular 1 and trocar sheath 2 all adopt medical grade plastic materials to make, the hardness of trocar sheath 2 is slightly larger than microtubular 1, the internal diameter of trocar sheath 2 is slightly larger than the external diameter of microtubular 1, its specification limit is as follows: the internal diameter 0.4-1.1mm of microtubular 1, external diameter 1.1-1.4mm, the internal diameter 1.1-1.4mm of trocar sheath 2, external diameter 1.5-1.8mm.The rear end of microtubular 1 links to each other with tee T 5, and a branched pipe connection of tee T 5 is taken out, charging device 6, and the structure of taking out charging device 6 is similar to small syringe, and another branched pipe of tee T 5 is connected with existing physiological pressure transducer 3.Sacculus 4, microtubular 1, take out, loop that charging device 6 and physiological pressure transducer 3 are connected to form sealing, be full of the liquid of sealing therebetween.
The using method of this utility model device is as follows:
1. monitor through stiffness of the waist spinal meninges exocoel: patient's flat lateral position of fetching water earlier; at waist 4; 5 intervertebral spaces point to head with No. 16 or No. 18 peridural anesthesia puncture needles (Touhy pin) inclined-plane and insert spinal epidural cavity; after puncturing successfully; pull back earlier and take out; the piston rod of charging device 6; the liquid of 4 li of sacculus just in time is evacuated fully to subside; trocar sheath 2 slowly being moved to rarefied sacculus forward just in time is collected in till the trocar sheath 2 fully again; rarefied sacculus 4 is under the protection of trocar sheath 2; send into spinal epidural cavity through puncture needle by scale; withdraw from puncture needle then; trocar sheath 2 under the actionless state in maintenance microtubular 1 position, is slowly moved to sacculus 4 backward and exposes trocar sheath 2 front ends fully.The physiological pressure transducer that is connected microtubular 1 rear end is realized being electrically connected with the pressure measurement main frame, zeroing, microtubular 1 and 2 usefulness immobilizations with adhesive tape are in lower back skin, and patient gets dorsal position and is convenient to continue to monitor then.With take out, after the propeller of charging device and main frame motor draw-in groove realizes being connected, press start key, take out, charging device 6 beginning slowly fills liquid from trend sacculus 4 in, till sacculus 4 saturations, computer display screen is retouched out a complete spinal epidural cavity sacculus internal pressure/sacculus amount of liquid curve (being balloon pressure/volume curve) automatically simultaneously.The main frame micro computer finds when consistent with cerebrospinal pressure according to curvilinear characteristic automatically, just sustainable monitoring.When monitoring finishes, press the pumpback key earlier, draw back inject the liquid of sacculus, sacculus is subsided, dial again except that microtubular 1 and sacculus 4.The monitoring maximum duration was 2 weeks.Before using, adopts by a whole set of sniffer conventional planning sterilization aseptic packaging.
2. exterior dura monitoring: patient gets dorsal position, selects conventional ventriculus dexter cerebri puncture of frontal angle point, and the circular bone of cranial drill 8-12mm hole after the local anaesthesia is peeled off the about 3 * 2cm of formation with detacher with cerebral dura mater around the bone hole and inner table of skull
2The chamber, the sacculus that will subside is sent into the cerebral dura mater exocoel, and microtubular 1 sutured is in scalp.With porus acusticus externus horizontal adjustment zero point, select main frame exterior dura pressure measurement function key, to take out, charging device 6 just begins just to stop automatically when a certain amount of from trend sacculus 4 topping ups, this moment, main frame showed that pressure monitors.Monitoring time is 1-2 week.
