Description

CT cerebral perfusion head fixing device

Technical Field

The utility model relates to a CT cerebral perfusion head fixing device, and relates to the technical field of CT cerebral perfusion inspection devices.

Background

Along with the development of medical examination technology, CT brain examination becomes more and more a common examination mode, at present, CT brain examination is examined through a patient lying on a CT examination device, a traditional CT brain perfusion examination device is provided with a head support, the head support is usually bigger than the head of a human body and can not fix the head, in order to solve the problem, the traditional CT examination device is usually provided with a binding belt to fix the head, but the strip structure can control the direction of freedom degree is insufficient and the loose effect is not good.

Aiming at the problem of poor head fixing effect in CT examination, a CT head scanning fixing device (CN 113288192A) is designed, the position of the CT head fixing device is automatically adjusted by an air pressure device so as to meet the requirements of people with different body types, and the pressure applied by a device with stronger patient movement can be increased.

Therefore, the existing CT fixing improvement apparatus uses a strong clamping and mechanical fixing manner to clamp and fix the head of the patient, whether the clamping and fixing force (CN 113288192 a) is increased according to the movement amplitude of the patient or (CN 214712578U) is applied in advance to fix the head of the patient.

To sum up, the prior art has the following drawbacks:

1. the conventional CT head fixation device cannot sufficiently fix the head of the patient, and the fixation manner adopted cannot provide sufficient stability, so the conventional CT head fixation device has a technical defect that the head of the patient cannot be sufficiently fixed.

2. The existing CT fixing and improving device clamps and fixes the head of a patient by using a strong clamping and mechanical fixing mode, the mode does not accord with humanized design, an appropriate warning device is added compared with the mode of fixing the head of the patient by using brute force, but the existing CT head checking and fixing device with warning function does not exist, so the existing CT brain checking and fixing device has the technical defect of not warning the patient function.

Disclosure of Invention

The utility model aims to provide a CT cerebral perfusion head fixing device, which solves the problems that the traditional CT cerebral perfusion checking device can not sufficiently fix the head and the traditional CT cerebral perfusion checking device has no warning function.

In order to achieve the technical purpose and the technical effect, the utility model is realized by the following technical scheme:

a CT cerebral perfusion head fixation device, comprising: the folding assembly and the limiting assembly are arranged in the limiting assembly.

Detailed Description

In order to more clearly describe the technical scheme of the embodiment of the present utility model, the embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

Examples

The embodiment of the present market describes a CT cerebral perfusion head fixing device, comprising: the folding assembly 2 and the limiting assembly 1 are arranged in the limiting assembly 1.

The limiting component 1 comprises a limiting block 101, a base 102 and a hanging hole 103, wherein the surface of the base 102 is horizontal, the limiting block 101 is arranged on the base 102, a groove 1011 for installing the folding component 2 is formed in the limiting block 101, and the hanging hole 103 is formed above the groove 1011.

The two limiting blocks 101 are symmetrical, the distance between the two limiting blocks 101 is between 10cm and 20cm, the CT is formed by wrapping the outer part of the limiting block 101 by a soft body, the soft body is identical to the shape of the limiting block 101, and the soft body is wrapped outside the warning block 201.

In this embodiment, the distance between the two limiting blocks 101 is 16cm, and the soft body is a sponge.

The folding assembly 2 comprises a warning block 201, a folding rod 202, a moving plate 204 and a hanging rope 203, wherein the moving plate 204 is connected with the base 102 through a spring, the folding rod 202 is connected with the moving plate 204, the warning block 201 is arranged at the tail end of the folding rod 202, two ends of the hanging rope 203 are respectively connected with the moving plate and the folding rod 202, and the hanging rope 203 penetrates through the hanging hole 103.

A cross rod is arranged in the groove 1011, the cross rod is in through connection with the folding rod 202 and is mutually perpendicular, the folding rod 202 comprises two independent rod bodies which are mutually hinged, a sleeve 2021 capable of moving along the rod bodies is arranged on the folding rod 202, and the sleeve 2021 is connected with the hanging rope 203.

In this embodiment, the cross bar is provided with a limiting device, the movable included angle range of the folding bar 202 is between 45 ° and 70 ° under the limiting action of the cross bar, the suspension rope 203 is a cotton-flax wire, and a small roller for reducing friction is disposed on one side of the sleeve 2021 adjacent to the folding bar 202.

The base 102 is provided with a fixing member 1021 for fixing the moving plate 204, and the moving plate 204 is provided with a small hole for connecting the fixing member 1021.

In this embodiment, the fixing member 1021 is of a hole-bolt fixing structure, the base 102 is provided with a column with holes, the diameter of the holes on the column is the same as that of the holes on the moving plate 204, and a rod body with a smaller size than the diameter can be inserted.

The materials described in this example are all non-metallic materials.

Before the patient checks, medical staff checks whether the fixing piece 1021 is kept fixed, confirms that the patient lies on the device after no error, places the head between the two limiting blocks 101, and at the moment, the sponge filled outside the two limiting blocks 101 can wrap the head of the patient inside, so that the head placing position of the patient is ensured to be accurate.

After the patient is lying, the rod body in the fixing member 1021 is withdrawn, and the device is changed from the fixed state to the movable state, and the movable plate 204 is kept at the lowest position under the pressure of the human body.

After the examination is finished, the medical staff reminds the patient not to move, the rod body for fixing the fixing piece 1021 is inserted into the fixing piece 1021 after entering the ct chamber, and then the patient stands up to complete the examination.
