Description

Adjustable arm supporting device

Technical Field

The invention relates to the technical field of medical instruments, and particularly discloses an adjustable arm supporting device.

Background

Placement of a Central venous Catheter (PICC) via a peripheral vein is performed by puncturing the vein from the peripheral arm using a Catheter that reaches the great vein adjacent the heart; at present, PICC catheterization is widely applied to patients with clinical tumor chemotherapy, irritant drug infusion, intravenous nutrition therapy and medium-and long-term intravenous infusion.

Put the pipe in-process at PICC, for guaranteeing aseptic regional maximize, need disinfect the whole arm of patient before putting the pipe, need fully raise patient's arm during the disinfection, some patients are tired after because of the chemotherapy, multifactor such as old age can not be raised the arm, aseptic gloves have been worn to both hands during the operator disinfection, can not touch the patient, consequently, need another nurse to lift and raise patient's arm, so that disinfect, however, the medical personnel of many hospitals need be responsible for patient a lot at present, medical personnel's work load is just very big originally, need two nurses to participate in when PICC puts the pipe, medical personnel's work load has been increased.

Disclosure of Invention

The invention aims to provide an adjustable arm supporting device, and solves the problem that the workload of medical workers is increased because two medical workers are required to carry out PICC (peripherally inserted central catheter) in the prior art.

In order to achieve the purpose, the basic scheme of the invention is as follows: adjustable arm strutting arrangement, including the lifting support, the upper portion of lifting support is connected with lifts the subassembly, lifts the subassembly and includes the layer board and grab the pole with holding in the palm, grabs pole fixed connection with holding in the palm on the layer board, is equipped with the palm male clearance of being convenient for between grabbing pole and the layer board with holding in the palm.

The basic scheme of the invention has the working principle and the beneficial effects that:

when this scheme of adoption, only need a medical personnel before disinfecting to the whole arm of patient, adjust lifting support's height earlier, in order to make things convenient for the patient to insert the palm by oneself in the clearance between grabbing pole and the layer board in one's hand, the patient is with holding the grabbing pole of hand, patient's arm will be unsettled aloft, in order to make things convenient for medical personnel to carry out whole disinfection to this unsettled arm, whole process does not need two medical personnel's cooperation to accomplish, so medical personnel's work load has been reduced in other words, the action of grabbing the pole through the hand simultaneously also makes patient's arm can keep the unsettled of relatively long-time lifting in the air with simple and convenient operation, in order to make things convenient for medical personnel to carry out holistic multiple disinfection to the arm.

Further, it still includes driver one, backup pad and slide to lift the subassembly, and backup pad fixed connection is in the output shaft of driver one, and slide sliding connection is equipped with first elastic component in the backup pad between slide and the backup pad, and layer board fixed connection is on the slide, and driver one drives the backup pad rotation, and the removal of slide is in order to make things convenient for the grab bar of hand to be close to or keep away from the patient.

Has the beneficial effects that: in the PICC catheter placement process, in order to fully expose the puncture part (the puncture part is positioned on the elbow), if the patient ensures that the arm is in a posture of about 90 degrees of abduction and 60 degrees of external rotation after disinfection, the puncture is convenient for an operator, and the puncture success rate can be improved; when the scheme is specifically implemented, the arms of the patient are expanded by about 90 degrees through the whole supporting device, after the arms of the patient are disinfected, the lifting support drives the arms of the patient to be lifted from the suspended state to the horizontally suspended state, the driver drives the supporting plate to rotate, the sliding plate, the supporting plate and the hand grasping rod are further driven to rotate by 60 degrees, the arms of the patient with the hand grasping rod rotate along with the hand grasping rod, and the success rate of puncture is improved; in this process, for making things convenient for lifting support to remove patient's arm to the level from the eminence, the slide will slide in the backup pad, has avoided dragging that causes patient's arm, has improved patient's comfort level.

Further, still include a supporting bench, the lifting support is connected on a supporting bench, and a supporting bench can be used for placing patient's arm.
