Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a portable hyperbaric oxygen therapy instrument for chronic wounds. Background Art

[0002] The local wound tissue is in a hypoxic state, and the oxygen partial pressure is between 5 and 10 mmHg. The hypoxic state will cause cell function disorders and make it difficult for the wound to heal. During hyperbaric oxygen therapy, the blood oxygen content of the patient can be increased by more than 10 times compared with normal pressure oxygen inhalation, improving local oxygen supply, thereby improving tissue microcirculation and aerobic metabolism, and promoting wound healing. Hyperbaric oxygen therapy has anti-inflammatory and anti-infective effects on wounds, can effectively control the growth of anaerobic bacteria, reduce toxin production, thereby effectively localize inflammation, improve local anti-infection ability, and hyperbaric oxygen therapy can promote tissue aerobic metabolism, thereby promoting the growth of granulation tissue and accelerating wound healing.

[0003] After the hyperbaric oxygen therapy instrument is used, oxygen still overflows from the oxygen delivery tube head part, which will cause oxygen waste and unsafe accidents. At the same time, the oxygen delivery tube head part is placed exposed outside, and is easily contaminated by bacteria, resulting in secondary infection of the patient during the treatment process.

[0013] Beneficial effects

[0014] 1. After the oxygen supply of the present invention ends, the oxygen inhalation tube box can be inserted into the docking sealing box by holding the handle. Then, the extrusion head first comes into extrusion contact with the sealing plate, causing the sealing plate to move outward until the sealing plate is stuck in the notch between the extrusion head and the stop lug. At this time, the sealing plate is in an open state, and the leaked oxygen in the oxygen inhalation tube box can be stored in the docking sealing box, saving oxygen and avoiding excessive leakage. At the same time, when the oxygen inhalation tube box is inserted into the docking sealing box, the trigger block causes the trigger column to move upward, triggering the trigger switch, and the protective sterilization box starts the sterilization work at this time, so as to ensure that the oxygen inhalation tube box part can always be in a sterile state, enabling patients to use it with confidence and further ensuring the use safety.

[0015] 2. In the present invention, a U-shaped unlocking rod is vertically and slidably installed on the unlocking frame. The front end of the unlocking rod is rotatably connected to a pulling rod through a pin shaft, and the other end of the pulling rod is rotatably connected to a connecting column. When the instrument needs to be used, only by pushing the unlocking rod forward, the sealing plate will move outward under the pulling of the guiding column, causing the sealing plate to separate from the guiding guard plate. At this time, the oxygen inhalation tube box part can be withdrawn, and the protective sterilization box stops the sterilization work. During the use process, the guiding guard plate is in an unfolded state, which is convenient for the use of the disposable oxygen inhalation mask part. At the same time, the high-light sterilization tube can assist in high-light sterilization of the patient's oxygen inhalation part, contributing to healing and recovery.
