Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

FIG. 1 is a cross-sectional view of a wound treatment device according to the present invention, centering on an exudate storage part 100.

The wound healing apparatus according to an embodiment of the present invention includes a sealing portion 620, a first conduit portion 300, an exudate storage portion 100, a body portion, a pressure sensor, a component sensor, and a level sensor.

Here, the sealing portion seals a portion of the wound tissue 600 so that the sound pressure supplied through the pneumatic pump P can be properly engaged. The seal typically consists of a foam 610 that fits into the shape of the wound 600 and a drape 620 that seals the foam 610.

One end of the first conduit part 300 is connected to the sealing parts 610 and 620, and the other end is connected to the exudate storage part 100. Through the first conduit part 300, the negative pressure provided from the pneumatic pump P is transmitted to the sealing parts 610 and 620.

As shown in FIG. 1, in the exudate storage part 100, a first conduit part 300 connecting the sealing part and the exudate storage part 100 is introduced into one side. The exudate storage part 100 has an internal space for storing the exudates 200 and 210 which are removed from the wound tissue part through the first conduit part 300. Also, a second conduit 310 connecting between the pneumatic pump and the exudate storage is introduced from the side or other side of the first conduit 300.

Conduit connection protrusions may be provided at the inlet portions of the first conduit portion 300 and the second conduit portion 310 so that the ends of the conduit portions 300 and 310 are inserted into the exudate storage portion 100. A sealing member (e.g., a sealing ring) for sealing the first conduit part 300 and the second conduit part 310 may be provided in the conduit connecting protrusion.

The main body includes a user interface (GUI) and a pneumatic pump and is connected to the exudate storage part 100 to connect the second conduit part 310, the exudate storage part (or canister) 100 and the first conduit part 300 Thereby controlling the wound healing apparatus so as to provide sound pressure to the wound tissue site. Further, a portion where the exudate storage portion 100 is mounted may be provided on one side of the body portion. The pneumatic pump is present in the main body part, and it is possible to use a pump or the like which uses a reciprocating motion of the diaphragm in response to the magnetic force generated by applying a current to the coil.

Also, in the wound healing apparatus, a pressure sensor, a component sensor, and a level sensor are included.

Here, when the level sensor provides a negative pressure to be supplied from the pneumatic pump to the effluent storage section 100 under the control of the main body section after the first conduit section 300 is closed with a valve (not shown) It is possible to determine to what level the exudate inside the exudate storage part 100 is filled up or the amount of empty space (remaining amount) in the exudate storage part 100 based on the slope of the absolute value of the sound pressure sensed by the pressure sensor sensing the pressure, Can be detected.

More specifically, assuming that the pneumatic pump supplies a constant value of sound pressure under the control of the main body, the absolute value of the sound pressure will rise rapidly when the interior of the exudate storage part 100 is full and the remaining volume is small. However, If the interior of the unit 100 is empty, the absolute value of the sound pressure rises relatively slowly due to the large volume of the remaining volume. Therefore, by detecting the rising slope of the absolute value of the sound pressure, it is possible to detect to what level the exudate inside the exudate storage part 100 is filled up or to what extent the void space (remaining amount) exists in the exudate storage part 100 . Further, through the test at the prototype stage, a calculation formula can be derived between the internal residual volume value (V) of the canister and the time rate of change (slope) of the absolute value of the supply pressure.

The component sensor may further include a first conduit 300 or a first conduit 300 within the exudate reservoir 100 that is formed to be flat and formed on both sides of the exudate reservoir 100, ) And the receiving unit 115 or 110, and the degree of the blood contained in the exudate 210 or the concentrations and components of the exudates can be inspected based on the signal result of the receiving unit corresponding to the signal application of the sending unit. The flattening of the first conduit part 300 takes into account light reception and current reception.

The component sensor is configured such that at least a part of the first conduit part 300 existing between the transmitting part and the receiving part is transparent or translucent so that the receiving part can receive the light emitted from the transmitting part, The degree of inclusion of the blood in the exudate, and the concentration or component of the exudate can be detected on the basis of the change in the intensity of the light.

In addition, the component sensor receives the current from the transmitter and receives the current from the receiver, and based on the change in the frequency of the signal received by the receiver, the intensity of the signal, the degree of inclusion of the blood in the exudate, Can be inspected.

In addition, the component sensor may further comprise an arrangement for inspecting the pH of the exudate and the gas released from the exudate.

Here, the component sensors may be constituted by one component, but may be constituted by component sensors using light and component sensors using current, or they may be provided in plural or plural positions.

The component sensor can visually or auditorily display the component corresponding to the infected product or the infecting organism in the component according to the information stored in the database through the GUI of the main body. Through this, the physician or nurse practitioner can intuitively recognize easily. Whether the component corresponds to an infected product or an infected organism can be stored in a memory in the body in advance based on the accumulated database.

As described above, the component sensor can be composed of two or more components, and it is possible to use a component corresponding to the infected product or the infecting organism in accordance with the combination information of two or more components stored in the database, It can be displayed visually or audibly. Through this, the physician or nurse practitioner can intuitively recognize easily. Whether a component corresponds to an infected product or an infected organism can be realized by storing the combination information of two or more component sensors in a memory in the main body based on a database in which a large amount of accumulated information is accumulated.

In addition, the component sensor displays the component corresponding to the infected product or the infecting organism in the component according to the information stored in the database, visually or audibly through the GUI of the main body, Patient case, diagnosis and prescription can be displayed together. Such similar case cases, diagnosis and prescriptions can be provided in cooperation with medical information or medical image systems such as PACS, DPS, and VNA in the hospital. Implementation of telemedicine based on the above-described component sensors is also possible in the future. An automated drug injection system that can be used in telemedicine will be described below with reference to FIG.
