Description

Cerebrospinal fluid drainage device

Technical Field

The utility model relates to a drainage device field especially relates to a cerebrospinal fluid drainage device.

Background

Cerebrospinal fluid drainage is divided into ventricular drainage and lumbar cisterna magna drainage. Cerebrospinal fluid drainage needs to control the drainage speed more strictly, for example, drainage speed is required to be 10-15 mL per hour for lumbar cisterna magna drainage, and excessive drainage should be avoided.

At present, the drainage speed is adjusted clinically mainly by adjusting the hanging height of a drainage bag of a cerebrospinal fluid drainage device; namely, the higher the hanging height of the drainage bag is, the more difficult the cerebrospinal fluid flows out, and the slower the drainage is; otherwise, the faster the drainage.

ZL201721472958.6 discloses a cerebrospinal fluid drainage device, and the device includes drainage bag, drainage bottle, drainage tube and flow regulator. The drainage bottle can be used to measure the drainage volume per hour to make the nurse learn whether drainage speed meets the requirements. The drainage speed can be adjusted by adjusting the flow regulator or adjusting the hanging height of the drainage bottle.

The effect of adjusting the drainage speed of cerebrospinal fluid by means of a common flow regulator is poor, and the requirement is often not met. The hanging height of the drainage bottle or the drainage bag is adjusted by adjusting the hanging height, so that a corresponding hanging device convenient for adjusting the height is required beside a patient bed.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the cerebrospinal fluid drainage device comprises a drainage bag 1, a measuring bottle 2, a drainage tube 5, a connecting tube 3, a first control switch 4, an expansion link 6 and an intermediate bottle 7; the measuring bottle 2 is made of hard transparent materials, and the measuring bottle 2 is provided with a liquid quantity mark 2-1 and a first breathing structure 2-3; the drainage bag 1 is positioned below the measuring bottle 2, the drainage bag 1 is connected with the measuring bottle 2 and communicated through a connecting pipe 3, and a first control switch 4 is arranged on the connecting pipe 3; the telescopic rod 6 is vertically arranged above the measuring bottle 2 and is connected with the measuring bottle 2; the middle bottle 7 is connected to the top end of the telescopic rod 6, and the middle bottle 7 is provided with a second breathing structure 7-1; the drainage tube 5 comprises a drainage tube front section 5-1 and a drainage tube rear section 5-2, the drainage tube front section 5-1 is connected with the middle bottle 7, and the drainage tube rear section 5-2 is connected with the middle bottle 7 and the measuring bottle 2.

The utility model discloses during the use, with 2 vertical fixes of measuring flask on sick bed keeps off or near other articles of patient, drainage bag 1 is connected with measuring flask 2, does not consequently need other modes to hang. Close first control switch 4, then the cerebrospinal fluid that the drainage goes out gets into measuring flask 2 and keeps in, and measuring flask 2 is the stereoplasm is transparent, can conveniently and comparatively accurately learn the drainage volume, regularly observes the record and can learn the drainage volume per hour to can judge the drainage speed fast and slow. After the drainage speed is known through regular observation, the drainage bag 1 is placed into the cerebrospinal fluid by opening the first control switch 4, and then the first control switch 4 is closed, so that next observation can be started.

When the drainage speed needs to be adjusted, only the telescopic rod 6 needs to be lengthened or shortened. Lengthening or shortening the telescopic link 6 has adjusted the height of middle bottle 7 promptly, and middle bottle 7 is located the highest point of cerebrospinal fluid drainage device, and the cerebrospinal fluid need overcome pressure just can cross middle bottle 7 and get into measuring flask 2. The higher the middle bottle 7 is, the more difficult the cerebrospinal fluid passes through the middle bottle 7 and enters the measuring bottle 2, so that the drainage speed becomes slow; otherwise, the drainage speed becomes faster. The middle bottle 2 is used for overcoming the siphonage phenomenon, otherwise, the speed regulation effect cannot be achieved, and therefore the middle bottle 7 is provided with the second breathing structure 7-1.

The utility model is the same as the existing cerebrospinal fluid drainage device in that a puncture needle 8 is also needed; in order to control the on and off of the drainage, a second control switch 9 may be provided on the drainage tube 5. The first control switch 4 and the second control switch 9 are switches commonly used on the drainage tube. The first control switch 4 may also be a medical valve with a rotary control switch. The first breathing structure 2-3 is used for ventilation, and prevents the pressure increase in the measuring bottle 2 from influencing the inflow of cerebrospinal fluid. The liquid amount mark 2-1 is conventional scale and scale value. The rear section 5-2 of the drainage tube should have a suitable length to accommodate the extension and retraction of the telescopic rod 6.

The middle bottle 7 only allows cerebrospinal fluid to pass through and overcomes the siphonage, so the middle bottle 7 only needs a small volume, the weight of the middle bottle is small, and the telescopic rod 6 does not need to provide a large supporting force. The telescopic rod 6 is designed as a conventional telescopic rod, for example in the form of an older television antenna. In order to more reliably prevent the telescopic rod 6 from being shortened, a tightening screw 6-1 may be provided as shown in fig. 3. The telescopic link 6 can be dismantled with measuring bottle 2 and intermediate flask 7 and be connected promptly the utility model discloses during the packing, do not connect, just connect during the use, so the utility model discloses occupation space is littleer when depositing.

In order to further facilitate the flow of cerebrospinal fluid from the intermediate bottle 7 into the measuring bottle 2 and avoid the storage of cerebrospinal fluid in the intermediate bottle 7, it is preferred that the bottom of the intermediate bottle 7 is inclined, and the connection point of the rear section 5-2 of the drainage tube with the intermediate bottle 7 is located at the lowest position of the intermediate bottle.

The specific mode of connecting the drainage bag 1 and the measuring bottle 2 can be as follows: the measuring bottle 2 is provided with a hanging lug 2-2, the drainage bag 1 is provided with a hanging belt 1-1, and the hanging belt 1-1 is hung on the hanging lug 2-2.

As mentioned before, the utility model discloses measuring flask 2 needs to be fixed during the use, can carry out measuring flask 2's fixed with the ribbon. The utility model discloses also can be from taking fixed knot to construct 10, fixed knot constructs 10 and is connected with measuring bottle 2. Thus, it is not necessary to additionally search for other objects to fix the measuring bottle 2. The securing structure 10 may be a conventional cable tie, clip, or the like.
