Abstract

The utility model discloses a CT bed capable of clamping the head of a patient automatically. The CT bed comprises a bed plate, the upper portion of the bed plate is provided with a lifting pillow, the bottom side of the pillow is connected with a pair of symmetric supports in a hinged mode, the supports are V-shaped, the uppermost end of each support is bent towards one side of the pillow, the bent portion of the bottom of each support is provided with a rotating shaft, the supports can rotate around the rotating shafts, and the topmost ends of the supports are provided with sponge bases. By means of the lever principle, gravity formed when the pillow is pressed down is converted into clamping force of the supports, after a patient lies down, the head of the patient can be automatically clamped and fixed, the situation that the head shakes in the CT scanning process is effectively avoided, and the CT bed has the advantages of being simple in structure, convenient to use, fixed and reliable.

Description

A kind of head is from clamping CT bed

Technical field

The utility model relates to a kind of CT bed, especially a kind of head is from clamping CT bed.

Background technology

In carrying out the process of CT scan, client need lies on CT bed, during especially to head scanning, need to keep head to fix, can not shake, because some patient does not have Autonomous Control ability, therefore in scanning process, be difficult to keep fixing, existing conventional fixing means is at head fixed clamp plate or fixes by restraining belt, but this fixing means bothers while using very much, especially some spirit are easy to exciting patient, this fixing means is difficult to play good fixed effect, affects image quality.

Utility model content

This utility model main purpose is to address the above problem and is not enough, provides a kind of simple in structure, easy to use, can automatically add and hold the fixing head of head from clamping CT bed.

The technical solution of the utility model is for achieving the above object:

A kind of head is from clamping CT bed, comprise bed board, the head of a bed one side of described bed board is provided with two transversely arranged square through holes, between square through hole, be provided with a cylindrical hole, the bottom center that a liftable medicated pillow, described medicated pillow are installed above cylindrical hole is fixed with one to the cylindrical bar of downward-extension, cylindrical bar is positioned at the cylindrical hole of bed board, is matched in clearance;

The inwall both sides of the square through hole of described bed board are provided with the arcuate groove concaving, in the bottom side of medicated pillow, be hinged with a pair of symmetrically arranged support, support is V-arrangement, topmost to medicated pillow curving, its bending place, bottom is provided with a rotating shaft, arcuate groove in rotating shaft and square through hole is slidably matched, and the top of described support is provided with sponge seat.

Further, a spring is installed between described bed board and medicated pillow, spring housing is on the cylindrical bar of pillow base, and under spring force effect, medicated pillow is positioned at highest order, makes support pendulum to maximum subtended angle place simultaneously, and while facilitating patient to lie down, head contacts with medicated pillow.

Content to sum up, a kind of head described in the utility model is from clamping CT bed, utilize lever principle, the gravity that presses down medicated pillow is changed into the clamping force of support, realized the fixing function of Automatic-clamping head after patient lies down, effectively avoided rocking of head in CT scan process, had simple in structure, easy to use, fixing reliable advantage.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Embodiment 1: as shown in Figure 1, a kind of head, from clamping CT bed, comprises bed board 1, and the head of a bed one side of described bed board 1 is provided with two transversely arranged square through holes, is provided with a cylindrical hole between square through hole.

As shown in Figures 2 and 3, the bottom center that a liftable medicated pillow 2, described medicated pillow 2 are installed above the cylindrical hole of bed board 1 is fixed with one to the cylindrical bar of downward-extension, cylindrical bar is positioned at the cylindrical hole of bed board 1, for matched in clearance, medicated pillow 2 is fixed and can be slided up and down along the cylindrical hole of bed board 1 by cylindrical bar.

As shown in Figure 3, inwall both sides at the square through hole of bed board 1 are provided with the arcuate groove 4 concaving, in the bottom side of medicated pillow 2, be hinged with a pair of symmetrically arranged support 3, support 3 is V-arrangement, topmost to medicated pillow 2 curvings, in its bending place, bottom, be provided with a rotating shaft, arcuate groove 4 in rotating shaft and square through hole is slidably matched, support 3 can rotate along rotating shaft simultaneously, the synchronous routing motion that slides and rotate of realizing, the top of described support 3 is provided with sponge seat 6, and during use, sponge seat 6 is clamped in patient head both sides.

For realizing after medicated pillow 2 is used, can automatically reset, a spring 7 is installed between bed board 1 and medicated pillow 2, spring 7 is enclosed within on the cylindrical bar of medicated pillow 2 bottoms, when patient head is left medicated pillow 2, under spring 7 elastic force effects, medicated pillow 2 highest order of rebounding makes support 3 pendulum to maximum subtended angle place simultaneously, while facilitating next patient to lie down, head contacts with medicated pillow 2.

Using method of the present utility model is: patient's guiding is lain on CT bed, make patient head pillow on medicated pillow 2, due to head action of gravity, medicated pillow 2 is pressed down, support 3 is under the drive of medicated pillow 2, around rotating shaft 5, rotate, rotating shaft 5 is slided along arcuate groove 4 simultaneously, realize the swing of support 3, make its sponge seat 6 topmost be clamped in patient head both sides, realization is fixing to head, conveniently carry out CT scan, after patient has been scanned, lift head, medicated pillow 2 is under the elastic force effect of spring 7, the highest order of rebounding, support 3 is opened simultaneously, make its pendulum to maximum subtended angle place, used convenient next time.

As mentioned above, given scheme content, can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
