Description

Medical pressure indicator

Technical field

This utility model belongs to a kind of medical apparatus and instruments, relates in particular to a kind of medical pressure indicator.

Background technology

In medical procedure, medical personnel need pay close attention to and grasp the inside and outside positive/negative pressure variation of human body at any time and intravenous injection pressure, extradural pressure, intraocular pressure, cranium are pressed the variation of equal pressure, so that adjust or take different treatment measures.

1, the measurement of intravenous injection pressure

When the doctor selects the medicine intravenous injection for clinical patients, can be injected into stably in patient's body for making medicine, the doctor need control intravenous injection constantly and press, and is steady relatively to reach injection pressure.Yet in the actual injection operating process, injection pressure does not often reach the relative equilibrium of requirement.This will influence the accuracy of liquid medicine injection injection volume.Therefore, in the intravenous injection of prior art operation, adopt a kind of replace manually carrying out the medication injections operation and the accurate medical injection booster of injection speed usually, inject auxiliary injection unit such as machine automatically and reach the requirement of relative equilibrium to realize injection pressure.But there is following defective in these auxiliary injection units: 1, can not substitute fully and manually inject mode, inject as anaesthetic.2, bulky, need certain working place.3, price is higher, is difficult to apply.

When using that manually the mode of injecting is injected, because injection pressure and injection speed not only need to rely on medical personnel's experience and feel to control, also need to obtain patient's cooperation, it is very big therefore manually to inject operation easier.

2, the measurement of extradural pressure

Medical personnel when carrying out epidural puncture, the variation that need measure hard membrane outer pressure for the correctness that guarantees puncture position.

3, intracranial pressure is measured

Clinically, patient's cranium pressure situation is very crucial diagnosis basis, but does not have expensive pressure instrumentataion at a lot of basic hospitals.

The utility model content

The purpose of this utility model is to provide a kind of structure small and exquisite, cheap, can disposable medical pressure indicator.This medical pressure indicator has can test fluid pressure and the function of the intrinsic pressure slight change in abdominal cavity, for medical personnel provide the visual indication effect, thereby solved measurement, the measurement of extradural pressure and defective and the problem that intracranial pressure measuring technique aspect exists that above-mentioned intravenous injection is pressed, this utility model can satisfy clinical demand fully.

For realizing the purpose of this utility model, the technical scheme that is adopted is:

A kind of medical pressure indicator is characterized in that: its structure is by loam cake, and lower cover and inner core three parts are formed, described loam cake, and the structure of lower cover and inner core is respectively:
