Detailed Description

The following detailed description is made with reference to the accompanying drawings.

Fig. 1, 2 and 3 show a wound care device. The wound care device comprises at least a rinsing part 1, a sensor 2 and a control part 3. The irrigation section 1 is configured to be capable of spraying an irrigation liquid to a wound to irrigate the wound. The sensor 2 is configured to be able to detect at least an angle between a spraying direction of the washing liquid by the flushing part 1 and a wound surface to which the spraying direction is directed. The control part 3 can at least acquire the included angle between the spraying direction of the washing liquid sprayed by the washing part 1 and the wound surface pointed by the spraying direction, which is detected by the sensor 2. In the case that the bathing part 1 is capable of spraying the washing liquid or is capable of being connected externally to a water source for supplying the washing liquid, the control part 3 is configured to control the bathing part 1 to spray the washing liquid to the wound surface at a washing angle within a certain threshold range based on at least an included angle between a spraying direction of the washing part 1 to spray the washing liquid and the wound surface to which the spraying direction is directed, which is detected by the sensor 2, so as to prevent the secondary injury of the wound caused by the wound being washed by the washing part 1 spraying the washing liquid perpendicular or close to perpendicular to the wound surface to which the washing part 1 is directed.

Preferably, the sensor 2 can also measure the length, width and depth of the wound. Preferably, the direction detected by the sensor 2 may be the same as the direction in which the jet of water of the rinsing element 101 is directed. Preferably, the direction detected by the sensor 2 can be changed synchronously with the change of the direction of the water jet of the flushing member 101. Preferably, the sensor 2 may be disposed above the flushing part 1.

Preferably, the irrigation angle may be defined as an angle between the irrigation liquid sprayed from the irrigation part 1 and the wound surface contacted by the water flow.

Preferably, the rinsing liquid can be divided into the following by source or component: tap water, physiological saline, surfactant (such as soap water and benzalkonium chloride), disinfectant (such as povidone iodine and chlorhexidine), and antibiotic solution. Preferably, the flushing liquid used in the flushing part 1 may be one or more of the flushing liquids mentioned above according to the actual application requirements. Preferably, a proper amount of surfactant can be added into the flushing fluid to reduce the surface tension between the flushing fluid and liquid in the wound and between the flushing fluid and solid in the wound, so that the biological membrane, the inactivated tissue, foreign matters and the like can be easily separated from the wound surface after being flushed by the flushing fluid.

The reason for the present disclosure to adjust the irrigation direction pointed by the irrigation element 101 to an irrigation angle within a certain threshold range from the wound surface pointed by the irrigation element 101 is: if the wound surface is washed with the mode that the flush fluid is perpendicular to or is close perpendicular to the wound surface, then the flush fluid is difficult to peel off fibrin membrane from the wound surface and gets rid of, and easily washes flush fluid, pollutant piece granule into the wound deep, and then causes tissue edema and pollutant to remain, also probably washes the bacterium to the wound depth.

Preferably, the approach perpendicular to the surface of the wound to which the bathing portion 1 is directed may be such that the direction in which the bathing portion 1 sprays the irrigating fluid makes an angle between eighty degrees and ninety degrees with the surface of the wound to which the bathing portion 1 is directed.

Preferably, the threshold range may be between thirty and forty-five degrees. Preferably, the threshold range may also be adjusted according to different practical application scenarios. Preferably, the flushing angle may also be set to a certain value. For example, the flush angle may be set to forty-five degrees. By the configuration mode, pathogenic microorganisms, pollutant particles and the like adhered to the wound can be washed away through the washing part 1, so that the carrying capacity of the pathogenic microorganisms of the wound is reduced, the necrotic tissue fragments and dirt of the wound are removed, and the wound healing is accelerated; furthermore, secondary injuries such as edema, flushing of contaminant particles into deeper tissues, etc. caused by flushing the wound with a flushing fluid perpendicular or close to perpendicular to the wound surface can be avoided.

According to a preferred embodiment, as shown in fig. 2, the flushing part 1 comprises at least a flushing element 101 and a moving element 102, the flushing element 101 being arranged above the moving element 102. The irrigation element 101 is used to spray irrigation liquid to the wound surface. The moving element 102 can receive data commands sent by the control part 3 to adjust the attitude of the flushing element 101 and/or the moving element 102. The control part 3 can adjust the posture of the moving element 102 and/or the flushing element 101 based on the acquired angle between the spraying direction of the flushing liquid sprayed by the flushing part 1 and the wound surface to which the spraying direction is directed, which is detected by the sensor 2, to achieve that the angle between the spraying direction of the flushing liquid sprayed by the flushing element 101 and the wound surface to which the spraying direction is directed is always kept within the threshold range.

Particularly preferably, the pose of the moving element 102 can be varied as the angle between the wound surface and the irrigation element 101 is varied.

Preferably, the direction of the spray of the irrigation liquid by the irrigation element 101 may be moved counter-clockwise or clockwise along the outer edge of the wound in a manner enabling a closed loop to be formed.

Preferably, the sensor 2 may be mounted on the side of the flushing member 101. Preferably, the direction in which the sensor 2 is directed may coincide with the direction of the flushing member 101 in which flushing liquid is sprayed, so that the sensor 2 can move with the movement of the flushing member 101. With this arrangement, the sensor 2 can transmit the angle between the flushing element 101 and the wound surface pointed by the flushing element 101 to the control part 3 in real time, so that the control part 3 can control the moving element 102 in real time, so that the angles of the flushing element 101 connected to the moving element 102 and the wound surface pointed by the flushing element 101 are always kept within the threshold range, thereby preventing the flushing liquid sprayed by the flushing element 101 from cleaning the wound surface at a flushing angle perpendicular or close to the flushing angle perpendicular to the wound surface.

Preferably, the moving element 102 is used to control the flushing angle of the flushing element 101. Through this configuration, control unit 3 can control washing element 101 through motion element 102 and spray the flush fluid to the wound surface of a wound with the washing angle of certain threshold range slant to make the flush fluid to the fibrin film on wound surface of a wound surface, shearing force of bacterium etc. bigger, in order to improve the washing effect of washing to foreign matter, pathogenic microorganism etc. in the wound, and can reduce the flush fluid and cause the probability that wound formation edema and/or bacterium deepened the wound.

According to a preferred embodiment, as shown in fig. 1 and 3, a camera 4 is also included. The camera 4 is used for shooting the wound surface condition of the wound and sending the wound surface condition to the control part 3. The control unit 3 can recognize the acquired wound surface condition and adjust the pressure of the irrigation fluid sprayed from the irrigation element 101 to the wound according to the recognized type of the wound surface, in order to prevent further damage to the wound by the irrigation fluid.

Preferably, the camera 4 may be arranged above the flushing member 101. Preferably, the direction in which the camera 4 is pointed may be substantially the same as the direction in which the rinse liquid is sprayed by the rinse element 101. Preferably, the image information and/or the video information captured by the camera 4 may be transmitted to the control section 3 in real time.

Preferably, the control unit 3 may identify the wound captured by the camera 4 by using an artificial intelligence image or a video recognition technique. Because the artificial intelligence image or video recognition technology is the prior art, and a person skilled in the art can also conveniently look up the relevant artificial intelligence image or video recognition technology, it is no longer repeated here how to recognize the wound by the camera 4. Preferably, the camera 4 can also adopt other technical solutions to identify the wound.

Preferably, the control part 3 identifies the received image information and/or video information representing the wound surface condition transmitted by the camera 4 to identify the wound surface type of the wound, such as small particle foreign matters and bacteria, large block foreign matters and necrotic tissues, pollutant particles, pathogenic bacteria, wound shape (e.g., oblique wound surface/small and deep wound surface), and the like.

For example, if the control unit 3 identifies that the wound surface photographed by the camera 4 belongs to a large wound based on the received image information and/or video information transmitted by the camera 4, the control unit 3 may control the moving element 102 to make the flushing element 101 and the wound surface pointed by the flushing element 101 form a flushing angle within a certain threshold range, and then attach to one side of the wound to start flushing, so as to facilitate flushing away bacteria and the like, and facilitate carrying away bacteria and the like by water flow. If the control portion 3 recognizes that the wound surface shot by the camera 4 belongs to a small and deep wound such as a puncture wound based on the received image information and/or video information transmitted by the camera 4, the control portion 3 may control the moving element 102 to flush the flushing element 101 deeply into the wound, so as to avoid poor flushing effect caused by insufficient water flow exchange in the wound.

Preferably, the control unit 3 is capable of adjusting the pressure of the irrigation liquid ejected from the irrigation unit 1 based on the type of the wound surface identified by the camera 4. Preferably, the flushing pressure can be graded in the following manner: low pressure is <5PSI, medium pressure is 5-8 PSI, high pressure is >8PSI. Preferably, the flushing pressure can also be classified in other ways.

Preferably, the control part 3 can adjust the pressure of the irrigation liquid supplied to the irrigation element 101 by the external irrigation liquid supply device by sending a corresponding control signal to the external irrigation liquid supply device in data connection with the control part 3.

Preferably, the control unit 3 can also display the pressure range of the pressure of the irrigation liquid required at the time to the medical staff, so that the medical staff can clean the wound through the irrigation element 101 manually, for example, the medical staff can clean the wound through the irrigation element 101 manually by using a needle or a transfusion tube.

Preferably, the flushing part 1 may also be provided with a pressure regulating element dedicated to regulating the pressure of the flushing liquid ejected from the flushing element 101, so that the control part 3 may adjust the pressure of the flushing liquid ejected from the flushing element 101 by sending a control signal to the pressure regulating element.

For example, if the type of the wound surface of the wound identified by the camera 4 is small particles and bacteria, the control unit 3 may adjust the pressure of the irrigation liquid ejected from the irrigation element 101 to a higher pressure, for example, 10PSI, by any of the methods described above. If the wound surface type of the wound identified by the camera 4 is a large foreign body and necrotic tissue, the control unit 3 may adjust the pressure of the flushing liquid ejected from the flushing element 101 to a lower pressure, for example, 4PSI, by any of the methods described above.

Preferably, if a certain wound type (e.g. large foreign bodies, small particles, pathogenic microorganisms, etc.) occupies the area of the wound surface of the wound and exceeds a certain threshold value, the wound type exceeding the certain threshold value is defined as the wound surface type of the wound. For example, if over fifty percent of a wound area is covered with small particles and bacteria, the wound surface type of the wound may be defined as small particles and bacteria. Preferably, the threshold value may be set artificially, for example, the threshold value may be eighty percent.

Preferably, the pressure of the irrigating liquid for debriding a wound jetted from the irrigating portion 1 may be set to the irrigating pressure of the irrigating liquid according to the type of wound detected by the sensor 2 and the sensor 2. By the arrangement, wound pathogenic bacteria, biological membranes, foreign bodies and the like can be cleaned, and on one hand, the situation that small particles and bacteria cannot be effectively removed due to too small flushing pressure is avoided; on the other hand, the device can also avoid soft tissue injury caused by overlarge flushing pressure and reduce the risk of flushing pollutants into deep tissues. Through this configuration mode, can shoot the wound through camera 4 to image and/or video transmission to the control unit 3 with the wound, control unit 3 discerns the wound condition that camera 4 was shot, and then control unit 3 adjusts the pressure of the flush fluid that washes 101 based on the wound type that discerns, makes wash element 101 wash the wound with the flush fluid of the pressure that matches with this wound type, thereby avoids the wound of low pressure to wash and is difficult to clear away the dense fibrin membrane in wound surface or the pressure is too high and probably leads to secondary damage.
