Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field more specifically, relate to a sickbed blood taking device. BACKGROUND

[0002] When the patient is blood sampling, needs to collect arterial blood, generally first selects from radial artery blood sampling. Since most examinations are all using venous blood examination, venous blood sampling is more close to skin surface layer due to the vein, and the difficulty of blood sampling is lower, and the pain of the patient is lighter, and the hospital currently uses simple soft pad to support the patient's forearm, and blood sampling can be smoothly carried out. But when radial artery puncture blood sampling is carried out, since the artery position is deeper, it is not easy to observe, and the patient's pain is more obvious when puncture is carried out, and the hand and arm will unconsciously move. The adult arterial blood gas analysis clinical operation practice standard points out that, taking radial artery blood sampling as an example, the upper limb is spread, the palm is upward, the finger is relaxed naturally, a soft pillow is placed under the wrist joint, and the wrist is kept overextended and positioned. But using simple soft pad can not fully expose the radial artery puncture blood sampling site, and also can not constrain the patient's hand action, and the patient's arm can not keep the posture suitable for blood sampling for a long time, so that the puncture failure rate is higher. When blood sampling is carried out, the operator needs to bind the patient's arm through the pressure bandage to carry out blood sampling,

[0003] In the ward, when the medical staff draws blood for the bedridden patient, most of them will adopt the blood sampling posture of recumbent position, and some patients have more examination items, so that there is a certain pollution risk when the operation is carried out on the patient's bed. The pressure bandage used for blood sampling is sterilized after each use, and the medical staff needs to clean and disinfect it after each patient uses it, and then repeatedly use it on the patient, which also has a certain pollution risk. For blood sampling of bedridden patients, the hands and arms of bedridden patients move unconsciously, which may have the possibility of blood sampling failure.

[0004] The Chinese patent document (authorized announcement number CN215306795U, application date 2021-06-16, authorized announcement date 2021-12-28) discloses a new radial artery blood sampling fixator, which comprises a base, a fixing belt and a handle. The upper part of the base is provided with a first inclined surface for supporting the forearm and a second inclined surface for supporting the back of the hand, the first inclined surface and the second inclined surface are both inclined downward and are arranged in intersection, the intersection is smoothly transitioned to form an upward arching surface, a first groove with a depth decreasing with the increase of the first inclined surface is arranged in the middle of the first inclined surface along the length direction, a second groove is arranged in the middle of the second inclined surface along the length direction, and the first groove and the second groove are smoothly transitioned at the arc surface. The fixing belt is arranged above the first inclined surface, and the two ends of the fixing belt are detachably fixedly connected with the base. The handle is arranged above the second inclined surface, and the handle is detachably fixedly connected with the base through the connecting belts arranged on the two sides. By using the utility model, the blood sampling site of the patient is stretched and fully exposed, and the medical staff is convenient for operation. When blood sampling by puncture, the patient can relieve the pressure by holding the handle, reduce the limb movement, and improve the blood sampling success rate.

[0005] However, the new radial artery blood sampling fixator only performs simple fixation through the fixing belt, cannot effectively limit unnecessary movement of the arm, and cannot create stable conditions for blood sampling operation, and does not consider that different patients have different arm lengths, thicknesses and diameters, the fixing belt is difficult to control tightness and force, and is prone to cause discomfort of the blood sampler. In addition, the new radial artery blood sampling fixator is not suitable for blood sampling of bedridden patients.
