Description

A convenient safe transfer car (buggy) of blood for hospital's internal medicine

Technical Field

The invention relates to the field of medical instruments, in particular to a convenient and safe blood transfer trolley for medical department in hospitals.

Background

Transfusion refers to a treatment method of infusing blood into a patient intravenously, and is widely used clinically. The therapeutic effects of blood transfusion are not only blood volume supplement, blood volume maintenance, blood pressure increase, shock resistance, and hemorrhagic shock prevention, but also oxygen-carrying erythrocytes are provided to correct acute anoxia or oxygen-carrying capacity decrease caused by erythropenia, and various blood coagulation factors of patients are supplemented to correct blood coagulation disorders. Therefore, different transfusion methods can be adopted according to different causes of patients so as to achieve different transfusion treatment purposes.

The blood transfusion commonly used in the medical department at present generally inputs blood cells, plasma proteins and platelets into a patient according to the requirement, and the blood separation products are all stored in a cold storage and have different storage temperatures and storage conditions. The preservation temperature of blood cells and plasma proteins is 2-6 ℃, the preservation temperature of platelets is 20-24 ℃, and the platelets need to be preserved by shaking. Therefore, before the operation, the blood products need to be taken out of the refrigerator, sorted and stored as required, and then transferred to the operating room.

Get the blood products that the thing board opened the back and can take out in it, pull forward the drawer again after taking out and can realize getting the closing of thing board for the temperature in the drawer can not disturbed by the external world. When blood products are required to be added into the drawer, the fetching plate is still in a closed state, the heat preservation performance of the drawer is not lost, and the drawer is pulled out, so that plasma proteins or blood cells can be added under the fetching plate. When closing the chamber door and taking the drawer backward travel, put the thing board and become the horizontality again, and get the thing board and can keep the horizontality motionless for this device makes operator's easy operation convenience in the maximize, keeps the temperature of blood storage unchangeable, has improved operator's work efficiency effectively, has improved the quality that blood was preserved.

2. This device can vibrate the save to the platelet as required, has improved platelet save time, has reduced the appearance of inactivation phenomenon: through the reciprocating movement of the reciprocating box and the left-right swinging of the swinging box, the platelets in the swinging box can realize sufficient vibration, the activity of the platelets is effectively improved, the platelets are prevented from deteriorating, and the safety of blood storage is improved. Can realize the antedisplacement of the platelet storage bag in the swing case through opening the top cap, can take out required platelet storage bag in getting the thing mouth, and put the thing mouth through adding fresh platelet storage bag in, through continuous opening the top cap can be with the platelet storage bag antedisplacement of rear side, realizes taking in order, has guaranteed the life of platelet effectively, has improved the storage efficiency of platelet.

3. This device convenient to use, and can not influence the blood preservation quality because ambient temperature when using: when the plasma protein and the blood cells of any blood type are needed, only the control knob corresponding to the blood type needs to be screwed, so that the stop screw head at the rear end of the control knob is screwed into the prismatic groove, and the stop screw is screwed into the through hole, so that the position fixation of the inner plate and the sleeve plate is realized. When the pulling handle makes the chamber door rotate, can take the articulated expansion plate swing with it, the fixed expansion plate of length just can take articulated drawer with it to stretch out forward, and the expansion plate of variable length just can swing the limit extension, can not take articulated drawer with it to remove to realize stretching out of appointed drawer, greatly improved the availability factor, reduced operator's operating procedure, and make blood products's storage more stable difficult rotten. The pull handle is pulled forwards, so that plasma proteins or blood cells placed in the drawer can move forwards, the operation principle that the plasma proteins or the blood cells are placed firstly and then are placed is realized, the time for an operator to search can be saved, the taking efficiency is improved, the temperature retentivity in the drawer is increased, and the storage of blood is facilitated.
