Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a blood circulation monitoring and temperature control device after replantation of severed fingers. Background Art

[0002] Finger replantation is a surgery that uses an optical microscope to re-anastomose the severed blood vessels, thoroughly clean the wound, and perform bone, nerve, tendon and skin repair. The key to the surgery is the connection of blood vessels, because the successful anastomosis of blood vessels is directly related to the survival and functional recovery of the replanted finger. In clinical practice, in the early stage after finger replantation, it is very important to observe the patient's blood circulation. Blood circulation observation can timely detect blood circulation disorders, reduce complications such as thrombosis, and promote finger survival.

[0003] Temperature monitoring is also an important indicator of the quality of blood circulation reconstruction after finger replantation. It can reflect the blood circulation reconstruction situation and judge blood circulation disorders by temperature. If the finger temperature is 4-5℃ lower than that of the healthy finger, it may mean that the blood circulation of the severed finger has been disturbed. It can also guide treatment decisions. According to the results of temperature monitoring, the doctor can judge the blood circulation of the replanted finger and formulate targeted treatment plans, such as adjusting the drug dosage, changing the bandaging method, etc.

[0004] However, in current clinical treatment, medical staff still rely on naked-eye observation of skin color, capillary return, swelling of replanted fingers and limbs, and other indicators to assess blood circulation, which increases the workload of medical staff; each person's observation will be different, which, to a certain extent, affects the continuity of observation;

[0005] In addition, the temperature measurement requires medical staff to measure the temperature of multiple patients' severed fingers at regular intervals, which greatly increases the workload of medical staff and is easy to forget, resulting in monitoring omissions and affecting the regeneration and recovery of severed fingers.

[0006] In addition, the medical staff's measurement of the temperature and blood oxygen concentration of the severed finger is fixed-point measurement, which cannot reflect the temperature and blood oxygen concentration of the entire severed finger, and the monitoring value is low in accuracy; and the medical staff are prone to touching the severed finger during manual measurement, and the sensitive capillaries around the severed finger are easily damaged, which in turn affects the normal recovery of the severed finger;

[0007] Therefore, the present invention discloses a blood circulation monitoring and temperature control device after finger replantation. Summary of the invention
