Automatic pressing medical application and control method thereof
Technical Field
The invention belongs to the technical field of compression hemostasis, and particularly relates to an automatic compression medical application and a control method thereof.
Background
At present, the cotton swab hemostasis by compression is clinically used for common patients, severe patients and patients without self-care ability are cotton balls, gauze pieces and a plurality of cotton swabs, the manual labor is needed, and sometimes, excessive pressing or insufficient pressing causes many complications: hemorrhage, hematoma, poor blood circulation in the extremities, etc. At present, clinic venous transfusion is cancelled clinically, most of patients need to be treated by venous transfusion in hospital, and particularly, critically ill patients need to be subjected to long-term large-amount transfusion. If the scalp needle is used for puncture to press the scalp, about 10 minutes is needed; although the venous transfusion is mainly performed by a shallow venous indwelling needle at present, the indwelling needle is left for 36-72 hours, and a puncture hole after the indwelling needle is pulled out is larger than that of a common scalp needle, the pressing time is longer, generally more than 3-5 minutes is needed, and particularly the pressing time of a patient with poor blood coagulation mechanism is longer. The compression time after arterial blood collection is complicated in clinic, and a nurse cannot press a puncture hole for a patient, and needs the patient himself or herself or family members and accompanying nursing to assist in pressing, for example, the problems of local skin redness, ecchymosis, subcutaneous hematoma and the like caused by poor compliance of the patient, family members or accompanying nursing, coma, inconvenience for the patient in limb movement, or critical illness state, the fact that multiple venous channels need to be established, repeated puncture is unsuccessful, pressing cannot be matched, insufficient pressing time and the like are caused; in addition, blood extravasation is easily caused by non-pressure application of puncture operation ports of various puncture operations such as abdominal puncture and chest puncture in clinic, so that the risk of infection is increased, and even the possibility of septicemia of patients with poor resistance is increased.
However, the dressing used for pressing the venous puncture of a critically ill patient clinically or for various puncture ports clinically is a common infusion paste, a finished product of an application tool with pressure is not available, and the conventional method is to press the venous infusion puncture by a cotton swab and then add the common infusion paste for fixation; the operation opening of the thoracentesis or the abdominal puncture is fixed by a common operation opening paste in the abdominal puncture bag. The clinical findings show that the cotton swab rod in the first mode is broken and then a plurality of bamboo sticks prick the head, so that the patient is easily pricked and the cotton swab rod is easy to fall off; the second mode is that when a large amount of pleural fluid and ascites occur, a large amount of seepage of the puncture is easy to leak due to the overlarge pressure in the thoracic cavity and the abdominal cavity.
Through the above analysis, the problems and defects of the prior art are as follows: the prior method can not adjust the corresponding pressing force according to time, thereby reducing the hemostatic effect; meanwhile, the hemostasis method cannot realize automatic pressing hemostasis, and consumes manpower.
