The utility model content

The purpose of this utility model, just provide a kind of monitoring and therapeutic apparatus that adopts single pump just can reach cerebrospinal fluid (CSF) drain, displacement, injection, pressure monitoring purpose, its disposable sebific duct is with low cost, install practicality easy and simple to handle, be easy to promote the popularization use, the more important thing is nature drain safety and reliability.

Second purpose of the present utility model, be exactly on the basis of above-mentioned monitoring and therapeutic apparatus, further to improve, monitoring and therapeutic apparatus can be detected the cerebrospinal fluid biochemical component that drain is come out to be shown, further, the cerebrospinal fluid that drain can be come out is handled, so as can with its again re-injection go into patient's intracranial or lumbar subarachnoid.

For achieving the above object, taked following technical measures: cerebrospinal fluid of the present utility model (CSF) drain, displacement, injection, pressure monitoring and therapeutic apparatus comprise that puncture needle puts pipe, union joint, pressure-measuring pipe, pressure transducer and CSF drain displacement injection pressure monitoring controller (being called for short the YJR instrument); Another termination pressure transducer, pressure transducer that the puncture backshank connects pressure-measuring pipe, pressure-measuring pipe link to each other with the YJR instrument; It is characterized in that: described pressure-measuring pipe is drawn a branch before connecing pressure transducer, tell two branches of drain and lavation in the branch again, automatic interrupter by the control of YJR instrument is housed in drain branch and lavation branch, electronic lavation pump is housed in the lavation branch, and described electronic lavation pump can be sigma pump, roller pump or syringe pump.

On the basis of abovementioned technology, this utility model also can be done further improvement: 1) be equipped with at described drain branch outlet and drip kettle, drip on the kettle enumerator is housed, dripping kettle has the external liquid containing bottle of pipe; 2) described liquid containing bottle has external tapping, and it inserts the CSF biochemistry detection interface of YJR instrument and can show testing result; 3) described liquid containing bottle has the CSF microporous filter membrane, CSF can be filtered out antibacterial, virus and leukocyte, erythrocyte etc., keeps composition and the osmotic pressure of former CSF, this CSF re-injection can be gone into disease intracranial or lumbar subarachnoid; 4) under the three way cock of the belt switch of pressure-measuring pipe cut-in pressure pick off, be lined with leakage prompting filter paper.

The beneficial effects of the utility model are, after having taked above-mentioned technical measures, cerebrospinal fluid of the present utility model (CSF) drain displacement injection pressure monitoring and therapeutic apparatus, all functions only adopt single pump just can reach cerebrospinal fluid (CSF) drain displacement pressure monitoring purpose in the scope of safety, its easy to operate and safe reliable, be easy to promote the popularization use, and, can the cerebrospinal fluid biochemical component that drain is come out be detected and show, further, the cerebrospinal fluid that drain can be come out is handled, so as can with its again re-injection go in the patient body.

This utility model not Dan Kejing waist places pipe, also can put pipe through the ventricles of the brain.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 adopts the theory of constitution sketch map of cerebrospinal fluid (CSF) the drain displacement injection pressure monitoring and therapeutic apparatus of syringe pump for this utility model first embodiment.

Fig. 2 adopts the local structure for amplifying sketch map of roller pump for this utility model.

Fig. 3 is that this utility model example adopts the local structure for amplifying sketch map of sigma pump.

The specific embodiment

Can see from Fig. 1, cerebrospinal fluid (CSF) the drain displacement injection pressure monitoring and therapeutic apparatus of this utility model first embodiment comprises that puncture needle places pipe 1, union joint 2, pressure-measuring pipe 3, pressure transducer 4 and CSF drain displacement injection pressure monitoring controller (being called for short the YJR instrument) 5 through waist; On the YJR instrument 5 microcomputer chip is housed, can carry out automatically control and showing of Computerized intelligentization according to menu, the tail end that puncture needle places pipe 1 through waist connects pressure-measuring pipe 3, pressure-measuring pipe 3 by union joint 2 the other end by a three way cock 15 connect pressure transducer 4, pressure transducer 4 links to each other with YJR instrument 5; A branch is drawn in another outlet of three way cock 15, tell two branches of drain and lavation in the branch again, electronic miniature injection lavation pump 71 is housed in the lavation branch, in drain branch and the lavation branch automatic interrupter 6 is housed, 8, two automatic interrupteres are electrically connected with the YJR instrument and are controlled by the YJR instrument according to detected CSF pressure, at the drain branch outlet kettle 9 is housed, drip on the kettle infrared counting device 10 is housed, drip the external liquid containing bottle 12 of pipe on the kettle, flow regulator 11 is arranged in the pipe, infrared counting device 10 and flow regulator 11 all are electrically connected with the YJR instrument, control flow regulator 11 by the YJR instrument according to enumeration data; Liquid containing bottle 12 has external tapping to insert CSF biochemistry detection pick off 13 interfaces of YJR instrument and can show; CSF microporous filter membrane 14 is arranged in the liquid containing bottle, CSF can be filtered out antibacterial, virus and leukocyte, erythrocyte etc., keep composition and the osmotic pressure of former CSF, this CSF re-injection can be gone in the patient body by the lavation pump; The three way cock of the belt switch of pressure-measuring pipe cut-in pressure pick off 15 times, be lined with filter paper 16.

In use, with puncture needle through lumbar subarachnoid (or through ventricles of the brain) puncture and intubation, cerebrospinal fluid (CSF) flows to pressure transducer along pressure-measuring pipe, pressure transducer changes the cerebrospinal fluid in the pressure-measuring pipe (CSF) pressure into the signal of telecommunication and is sent to YJR instrument test section, and can on display screen, show, switch 6 at ordinary times, 8 are in closed condition, when only needing drain, the control of YJR instrument is opened switch 8 and can be reached the nature drain, the YJR instrument can also be controlled the speed that flow regulator 11 is regulated drain, fool proof reliable, the CSF biochemistry detection part 13 of YJR instrument also can demonstrate the biochemical component data of cerebrospinal fluid (CSF), and the CSF filter that CSF microporous filter membrane 14 is arranged by in the liquid containing bottle can filter out antibacterial with CSF, virus and leukocyte, erythrocyte etc., the composition and the osmotic pressure that keep former CSF are gone into this CSF re-injection in the patient body again.When singly needing lavation, switch 8 is closed in the control of YJR instrument, opens switch 6 and gets final product, when need are replaced, the YJR instrument can be interrupted the purpose that reaches displacement CSF by gauge tap 6 and switch 8 one open-one closes, and the leakage that the three way cock is lined with for 15 times prompting filter paper 16 can point out to have or not leakage.

The electronic lavation pump that Fig. 2, shown in Figure 3 and Fig. 1 are only adopted is different, is respectively sigma pump 72 or roller pump 73, can also be other medical electrodynamic pump certainly, and this all falls into protection domain of the present utility model.
