Abstract

The invention relates to a medical accurate height-adjustable scale and a use method thereof. The medical accurate height-adjustable scale comprises an infusion rack body. The medical accurate height-adjustable scale is characterized in that a vertical vernier caliper is welded with the middle part of a vertical pole of the infusion rack body; a laser pointer is horizontally welded with the vernier scale of the vernier caliper; and laser which is transmitted by the laser pointer and inside surface of the vernier scale are in one horizontal surface.

Description

A kind of medical accurate adjustment height scale and using method thereof

Technical field

Present invention relates to a kind of medical accurate adjustment height scale and using method thereof.

Background technology

At present when neurosurgical patients is carried out clinical treatment particularly aftertreatment, the lumbar cistern drainage pipe to patient's waist, the ventricles of the brain of brain, wound chamber drainage tube management particularly important.For there is the patient of intracranial hypertension, conventional regulative mode is through drainage tube and out and is stored in external drainage bag, liquid drains such as the cerebrospinal fluid of intracranial to reduce intracranial pressure.When intracranial pressure is less than standard value, it is desirable to reduce drainage flow is to avoid intracranial pressure too low.And realize this purpose and mainly regulate drainage flow affect intracranial pressure by the relative altitude of regulation drainage bag.

Therefore, by liquid drains such as the cerebrospinal fluid of intracranial out and when being stored in external drainage bag, drainage bag is the most crucial relative to the difference in height of patients head, and this difference in height directly influences the speed that the liquid such as cerebrospinal fluid flow out.There is a solution such as Chinese patent 201320378827.7 at present, medical adjustable hook rack, including hook (2), including marking graduated scale bar (1), described hook (2) is socketed on scale bar (1), and hook (2) is fixed on scale bar (1) by hook keeper (22).The program is at drip stand subscript high scale, is marked the height of hook by scale.But the program has an essential defect, i.e. 0 graduation position of scale bar (1) will not follow the height change of draining hole and adjust.In practice, because reasons such as sick bed height, pad blanket thickness, pillow thickness, patient's head size, patient postures change (leaning to one side to sleep or sleep towards sky), the height of draining hole is constantly in change up and down.Therefore, when using the technical scheme such as Chinese patent 201320378827.7, the height of hook is not the height between hook and draining hole, but the height between hook and 0 scale of scale bar (1), and these 2 are the most not consistent.

It is thus desirable to design a kind of 0 graduation position can follow the height change of draining hole and the scale that adjusts.

Summary of the invention

In view of this, in order to solve the problems referred to above, scale that this kind of 0 graduation position of novel offer can be followed the height change of draining hole and be adjusted and using method thereof.

A kind of medical accurate adjustment height scale, including drip stand body, it is characterized in that, a vertical slide gauge it is welded with in the middle part of the vertical rod of described drip stand body, one laser pen of level welding on the vernier cursor of described slide gauge, laser and vernier cursor medial surface that described laser pen is launched are in same level.

Further, the main scale part of described slide gauge is 500mm.

A kind of medical accurate adjustment height scale using method, comprises the steps:

Step 1, opens laser pen, adjusts vernier cursor up and down, the datum mark that the red alignment projected by laser pen needs；

Step 2, by formula: the relative altitude between drainage bag and datum mark=main scale scale-vernier graduation, retrodicts out the height that drainage bag on main scale scale needs to be adjusted to according to relative altitude.

Beneficial effect；Utilize vertical slide gauge, the laser pen of level, the rectilinearity of laser and vernier cursor and the direct verticality of main scale, datum mark (draining hole on patient's head) is flatly incident upon inside vernier cursor on horizontal plane.Utilize and keep the feature vertically moved between vernier cursor and main scale, do not move front vernier cursor medial surface alignment main scale 0 scale and the scale that carries of main scale, by simple formula: the relative altitude between drainage bag and datum mark=main scale scale-vernier graduation, retrodict out because the moving up and down of basic point simply, and need the height adjusted on main scale.

Slide gauge is originally the measurer for measuring length, internal-and external diameter, the degree of depth, and its former using method is L(size value)=integer part+fractional part.But the feature in itself structure (keeping between vernier cursor and main scale vertically moving, not moving front vernier cursor medial surface alignment main scale 0 scale and the scale that carries of main scale) can be applied to mark a mobile basic point position on the scale dexterously.Mark draining hole position plus laser pen emitting linear laser, solve " 0 graduation position can be followed the height change of draining hole and be adjusted " cleverly.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present invention.

Detailed description of the invention

With reference to Fig. 1, a kind of medical accurate adjustment height scale, including drip stand body 1, a vertical slide gauge 3 it is welded with in the middle part of the vertical rod of described drip stand body 1, one laser pen 4 of level welding on the vernier cursor of described slide gauge 3, laser and vernier cursor medial surface that described laser pen 4 is launched are in same level.The main scale part of described slide gauge 3 lengthens to 500mm.

A kind of medical accurate adjustment height scale using method, comprises the steps:

Step 1, opens laser pen 4, adjusts vernier cursor up and down, benchmark (draining hole) point that the red alignment projected by laser pen 4 needs；

Step 2, by formula: the relative altitude between drainage bag and datum mark=main scale scale-vernier graduation, needs to be adjusted to height according to relative altitude drainage bag on main scale scale of retrodicting out.

Claims (3)
