Description

Medical injection chair with warm-keeping function

Technical Field

The invention relates to a medical injection chair, in particular to a medical injection chair with a warm-keeping function.

Background

Medical Chinese interpretation: 1. and (3) treating the disease. The Chinese medical history is thousands of years, and the word eye appears in recent decades, which is a new word eye for international connection, and the treatment is mostly used before. However, medical care also includes healthcare content.

The transfusion chair is a chair used for transfusion of a patient.

The transfusion chair is also called a transfusion chair and is mainly used for transfusion for patients in medical units. In the early stage, a very simple chair or sofa is adopted, so that the quality, safety and usability are poor.

After the diagnosis of a doctor is finished, a patient needs to be treated by infusion for certain specific diseases, the infusion takes a long time, and the patient cannot do large-amplitude movement after the infusion needle is inserted into the body of the patient, so that a relatively stable environment is needed, the patient usually can choose to sit on a chair special for a hospital, and the infusion chair meets the requirement of ergonomics and can reduce the fatigue degree of the patient in the infusion process.

Because the patient needs to sit on the transfusion chair for a long time, the patient is easy to catch a cold if the patient does not carry certain warm-keeping articles when the weather is cold and the hospital environment for visiting is poor; meanwhile, as hospitals belong to public places, the transfusion chair for patients to sit is usually of a hard plastic or iron structure, and a certain cushion is not used for buffering, so that the patients feel certain discomfort after sitting on the chair; moreover, because the design of the common transfusion chair only requires sitting and resting, no redundant space is provided for placing personal articles, which causes certain inconvenience for patients.

Therefore, the development of an injection chair which has a warm-keeping function, can place certain personal articles for a patient and provides a comfortable infusion environment for the patient is urgently needed.

Disclosure of Invention

In order to overcome the problem that the patient is easy to catch a cold if the patient does not carry certain warm-keeping articles because the patient needs to sit on the transfusion chair for a long time; the transfusion chair for patients to sit is usually of a hard plastic or iron structure, and patients feel certain discomfort after sitting on the chair; the design requirement of a common transfusion chair does not have redundant space for placing personal articles, thus causing the defect of certain inconvenience to patients, and the technical problem of the invention is as follows: provides an injection chair with warm-keeping function for medical treatment, which has warm-keeping function, can place certain personal articles for patients and provides comfortable transfusion environment for patients.

An operator rotates the hand lever 293 to enable the hand lever 293 not to block the pull plate 2810 any more, so that the collection frame 2809 can be pulled out of the box body 4, at the moment, the torsion spring 295 generates elastic deformation, the operator loosens the hand lever 293 after the collection frame 2809 is reset, the hand lever 293 is driven to be in a state of blocking the pull plate 2810 again under the action of the torsion spring 295, so that the collection frame 2809 can be prevented from being separated from the box body 4 due to external force, the reliability of the invention is ensured, and meanwhile, the limiting block 294 can prevent the hand lever 293 from being separated from the fixed rotating rod 291.

Because the blanket rolling machine further comprises a guide mechanism 30, the guide mechanism 30 comprises a support 301, a third rotating shaft 302 and guide wheels 303, the support 301 is symmetrically arranged above and below the inner left and right side walls of the box body 4, which are provided with the first through holes 25, the third rotating shaft 302 is arranged on the support 301, and the guide wheels 303 matched with the blanket roll 24 are arranged on the third rotating shaft 302. In the process of pulling out and withdrawing the box body 4 of the carpet roll 24, the guide wheel 303 contacts the surface of the carpet to guide the carpet to a certain extent, so that the carpet can move more stably.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
