Oxygen treatment device for wound treatment {OXYGEN TREATMENT DEVICE TO HEAL WOUNDS}

The present invention relates to an oxygen treatment device for wound treatment, and more particularly, to a treatment device that helps rapid recovery of a wound by intensively providing oxygen to the wound while shielding the locally generated wound from the outside. .

Among the treatments, oxygen therapy refers to a treatment method in which breathing is performed for 1 to 2 hours with 100% pure oxygen in a chamber with air pressure 2 to 5 times higher than the general breathing environment.

Oxygen therapy is recognized as an auxiliary treatment that improves the effectiveness and quality of direct treatment by effectively supplying oxygen to tissues damaged by trauma, inflammation, bacterial infection, or edema. It was used for quick recovery of patients who suffered from diving sickness due to frequent occupational diving or high-risk occupational workers working in fire sites or confined spaces.

However, in recent years, the application range is gradually expanding to patients with diabetic complications, various intractable wounds, burns, and acute or chronic diseases.

In particular, a number of papers that applied oxygen therapy to treat chronic diabetic foot ulcers (diabetic foot) reported that the wound healing effect was improved by 33% compared to the group without oxygen therapy, and the risk of amputation was reduced by 71%. It has published research results.

According to these research results, some effects of oxygen therapy have been acknowledged in Korea, and in the case of patients with diabetic foot ulcers who have undergone graft or flap surgery, oxygen therapy is covered by limited insurance coverage.

The oxygen treatment unit 130 is a component specially prepared to directly and intensively perform oxygen treatment on wounds caused locally by various causes.

These oxygen treatment units 130 are individually manufactured in various forms as shown in FIG. 3 so that oxygen can be intensively supplied corresponding to the size and shape of the local wound, thereby configuring a plurality of sets.

At this time, the oxygen treatment unit 130 is selected according to the size and shape of the wound, attached to and detached from one end of the supply tube 110, attached to the wound, and then oxygen supplied from the oxygen supply source 10 is continuously supplied to the wound. Oxygen therapy is performed by ejection.

Stable oxygen supply to the wound is possible without a sense of heterogeneity.

Conversely, if the second discharge part 134 is made of a material having plasticity, that is, a structure in which a metal wire freely plastically deformed inside the material having elasticity described above is installed, the deformed state is firmly maintained according to the three-dimensional shape of the wound, As the wound dressing material 160 is more tightly fixed to the wound site, stable oxygen supply to the wound can be achieved.

The reinforcement tube 136 is stable without oxygen clogging between the supply tube 110 and the first and second discharge parts 132 and 134 or between the multi-tube fitting 150 and the first and second discharge parts 132 and 134 to be described later. As a tube-shaped component prepared to be provided to the first and second discharge units 132 and 134, a tube that is freely bendable but can prevent clogging of the pipeline due to bending or twisting is cut into various lengths and selectively as needed. will use

More specifically, the reinforcement tube 136 according to an embodiment of the present invention is basically made of medical TPE / TPU, PVC or silicone, which is resistant to bacterial erosion, has excellent chemical resistance, durability, hypoallergenicity, non-adsorption, water repellency and elasticity. As shown in the enlarged view of FIG. 1 in the flexible coating 136a made of a material, it may be a tube reinforced by embedding or integrating a coiled spring 136b or a woven wire 136c.

Oxygen that has passed through the check valve 120 of the supply tube 110 due to the reinforcing tube 136 is continuously and stably supplied to the first and second discharge units 132 and 134 without blockage of the pipeline even if the patient moves excessively. can become

The infrared lamp 138 is a component provided in the first discharge part 132 and the second discharge part 134 to further promote wound healing together with the supply of oxygen. As shown in FIG. 3, A plurality of them may be installed in a spaced-apart arrangement between the above-described micro-ejection holes H adjacent to each other.

As shown in FIG. 3, the infrared lamp 138 is composed of an LED element emitting infrared rays and is connected to a control device (not shown) installed in a protective case C, which will be described later, and control applied through the control device. By turning on or off by power, infrared rays of a predetermined wavelength are radiated to the wound.

Due to the infrared rays emitted in this way, surrounding tissues including the wound can be more quickly recovered as oxygen supply as well as blood circulation are promoted, and sedation and pain relief are enhanced.

Oxygen treatment unit 130 of the present invention, composed of a plurality of sets including the above-described configurations, corresponds to the size and shape of a locally generated wound, and at least one of them is used at the same time, so that a plurality of wounds As well as treatment for , oxygen treatment itself can be performed more intensively and effectively.

Notification unit 140, when clogging by foreign substances or bending or twisting of the conduit occurs on the entire conduit through which oxygen flows and is discharged from the check valve 120 to the oxygen treatment unit 130, immediately and intuitively It is a component that generates a warning sound.

As a result, the patient or medical staff can take measures to ensure that oxygen is supplied quickly and smoothly.

In order to specifically implement the above functions or actions through compact and simple mechanical means rather than complicated electrical means, the notification unit 140 according to an embodiment of the present invention, as shown in FIG. It may be configured to include a tube 142, a safety valve 144, and a whistle 146.

Here, the bypass tube 142 is connected to the supply tube 110 to bypass the check valve 120, so that even if the check valve 120 is blocked by a failure, a flexible supply of oxygen to the oxygen treatment unit 130 is achieved. It is a component of the tubular shape.

The safety valve 144 is installed in the bypass tube 142 communicating with the supply tube 110, and opens when the internal pressure of the bypass tube 142 is higher than the set pressure and closes when the pressure is lower than the set pressure. However, since a small commercially available one-way valve that can operate as above is sufficient, it is not particularly limited.

However, the safety valve 144 according to the embodiment of the present invention is elastically deformed when the internal pressure of the bypass tube 142 rises above the set pressure according to the increase in the internal pressure of the supply tube 110 due to clogging and opens the pipeline. It can be implemented as a valve type.

At this time, the safety valve 144 firmly maintains the closed state at the pressure of oxygen sent from the oxygen supply source 10, that is, at a delivery pressure within a predetermined range, and at an arbitrarily set predetermined pressure (for example, twice the delivery pressure). In may be a valve type valve made of a material having an elastic force to open.
