DETAILED DESCRIPTION

[0063] like Figures 1 to 7 As shown, the present solution provides a portable hemostatic dressing device, including a hemostatic module 100 and a dressing module 200;

[0064] The two hemostasis modules 100 are symmetrically arranged;

[0065] The two bandaging modules 200 are disposed between the two hemostasis modules 100, and the two ends are respectively connected to one hemostasis module 100;

[0066] The hemostasis module 100 includes an expansion washer 110 and an adjustment mechanism 120;

[0067] The expansion gasket 110 can expand when inflated, compress the patient's limbs, and reduce wound bleeding;

[0068] The adjustment mechanism 120 can inflate the expansion gasket 110 and monitor the air pressure in the expansion gasket 110 , and stop pressurizing the expansion gasket 110 after reaching a set value;

[0069] The bandaging module 200 includes a winding assembly 210 and a guiding assembly 220;

[0070] The guide assembly 220 is disposed on the outer wall of the expansion washer 110 and is rotatably connected to the expansion washer 110;

[0071] With the cooperation of the winding component 210 and the guide component 220, the gauze 230 in the winding component 210 can be wrapped around the patient's wound.

[0072] When using the device to bandage a patient's limbs such as arms and legs, the injured limb is passed through the two expansion gaskets 110 in turn, and then the expansion gasket 110 is inflated through the adjustment mechanism 120 to squeeze the patient's limb on the proximal side to achieve the purpose of hemostasis. After the wound is disinfected, the winding component 210 is driven to rotate through the guide component 220, so that the gauze 230 on the winding component 210 is wrapped around the patient's wound to complete the bandaging work.

[0073] The adjustment mechanism 120 is more preferred, and the expansion gasket 110 can be set to a larger size to facilitate the passage of limbs; it can also be set to a variety of sizes and models, respectively adapted to the legs and arms, to maximize the convenience of wearing and avoid secondary injury caused by contact between the wound and the device; and the hemostasis module 100 adopts a symmetrical design, and there is no need to find the direction when using it. The affected limb can be directly put in, and the air pressure of the expansion gasket 110 on the proximal side can be adjusted to complete the hemostasis operation.

[0074] In this embodiment, the shape and structure of the expansion washer 110 are as follows: Figures 1 to 3 As shown:

[0075] The expansion gasket 110 includes an expansion outer ring 111, an expansion inner gasket 112, and a guide outer ring 113;

[0076] A guide outer ring 113 is provided on both sides of the expansion outer ring 111;

[0077] The expansion outer ring 111 is in communication with the expansion inner cushion 112 and has a gas passage inside;

[0078] The outer walls of the expansion inner cushion 112 are in contact with the two guide outer rings 113 respectively.

[0079] Specifically, the cross-section formed by the expansion outer ring 111 and the expansion inner pad 112 is in a convex shape, and the two guide outer rings 113 are respectively arranged on the steps on both sides of the convex shape; the expansion outer ring 111 and the expansion inner pad 112 are combined and processed together by hot melting, and when the gas channel is inflated, the expansion outer ring 111 and the expansion inner pad 112 can expand at the same time.

[0080] In this embodiment, regarding the shape and structure of the adjustment mechanism 120, as shown in FIG. Figure 1 , Figure 3 and Figure 4 As shown:

[0081] The adjustment mechanism 120 includes a fixed casing 121, an air pump 122 and a pressure sensor 123;

[0082] The lower part of the fixed card shell 121 is fixedly connected to the outer walls of the two guide outer rings 113 respectively;

[0083] The air pump 122 is disposed at the center of the fixed housing 121;

[0084] One end of the air pump 122 is connected to the expansion outer ring 111, and the other end is connected to the fixed card shell 121 and extends outward;

[0085] A pressure sensor 123 is provided on each side of the air pump 122;

[0086] A fitting concave block 124 is provided at one end of the pressure sensor 123 close to the expansion outer ring 111;

[0087] The fitting protrusion abuts against the expansion outer ring 111;

[0088] A pressure controller 125 is provided at one end of the pressure sensor 123 away from the expansion outer ring 111;

[0089] The pressing controller 125 can control the opening and closing of the air pump 122 after being pressed;

[0090] The pressure sensor 123 can monitor the pressure value in the expansion outer ring 111, and when the set value is reached, the air pump 122 is controlled to be turned off.

[0091] Specifically, the adjustment mechanism 120 adopts a control mode that combines manual control and automatic control. After touching the pressing controller 125, the air pump 122 can be started to inflate the expansion gasket 110. During the inflation process, the user can touch the pressing controller 125 again to turn off the air pump 122 in advance before the value checked by the pressure sensor 123 reaches the set value according to his or her own body feeling and the bleeding condition of the wound; in addition, one of the symmetrically arranged pressing controllers 125 can start the air pump 122 with a single touch, and can turn off the air pump 122 by touching it again. After the other one is started, the exhaust program can be started to extract the air in the expansion gasket 110, so as to facilitate the patient to remove the device.

[0092] In this embodiment, regarding the shape and structure of the winding assembly 210, as shown in FIG. Figure 1 , Figure 5 and Figure 6 As shown:

[0093] The winding assembly 210 includes a pressure control pump 211, a connecting rod 212, a gauze reel 213 and an elastic connecting tube 214;

[0094] One end of the connecting rod 212 is fixedly connected to the axis of the pressure control pump 211;

[0095] The elastic connecting tube 214 and the gauze reel 213 are sleeved with the connecting long rod 212 in sequence from the direction close to the pressure control pump 211 to the direction away from the pressure control pump 211;

[0096] One end of the elastic connecting tube 214 is sealed and connected to the pressure control pump 211, and the other end is sealed and connected to the gauze reel 213;

[0097] The gauze reel 213 is slidably connected to the connecting long rod 212;

[0098] There is a gap between the elastic tube 214 and the connecting rod 212;

[0099] The gas outlet 2111 of the pressure control pump 211 is disposed in the gap.

[0100] Specifically, when the pressure-control pump 211 is pressurized, the air outlet 2111 inflates the gap between the elastic connecting tube 214 and the connecting long rod 212 to expand the elastic connecting tube 214; when the pressure-control pump 211 is depressurized, the air outlet 2111 draws air into the gap between the elastic connecting tube 214 and the connecting long rod 212 to shrink the elastic connecting tube 214, thereby controlling the movement of the gauze roll 213.

[0101] In this solution, the guide assembly 220 includes an arc-shaped connecting shell 221 and a contact plate 222;

[0102] An arc-shaped connecting shell 221 is respectively provided on both sides of the contact plate 222;

[0103] A guide slide bar 223 is provided on one side opposite to the two arc-shaped connecting shells 221;

[0104] The guide slide bar 223 is slidably connected to the guide outer ring 113;

[0105] One end of the pressure control pump 211 away from the elastic connecting tube 214 and one end of the connecting rod 212 away from the pressure control pump 211 are fixedly connected to an arc-shaped connecting shell 221 respectively.

[0106] Due to the sliding connection between the guide slide bar 223 and the guide outer ring 113, under the control of external force such as manual intervention or motor-controlled driving method, the arc-shaped connecting shell 221 drives the connecting long rod 212 to rotate, thereby causing the gauze roll 213 to rotate around the axis of the arc-shaped connecting shell 221.

[0107] When bandaging, first wrap the end of the gauze 230 around one side of the patient's wound, then control the guide component 220 to drive the gauze reel 213 to slide along the connecting long rod 212, while allowing the gauze reel 213 to rotate around the patient's affected limb, thereby allowing the gauze to be wound around the patient's wound in a spiral manner; the control of the guide component 220 can make the gauze 230 move evenly, so that the gauze 230 is evenly wrapped around the patient's wound.

[0108] Preferably, the two bandaging modules 200 are arranged in opposite directions. When the wound area of ​​the patient is large, the two gauze rolls 213 are arranged on both sides of the wound. When the gauze 230 rotates and wraps around the wound, they slide toward each other, thereby ensuring that the winding efficiency of the gauze 230 is improved from both sides and saving bandaging time.

[0109] In this scheme, if Figure 7 As shown, a plurality of touch pressure rods 224 are provided on one side of the contact plate 222 close to the expansion washer 110;

[0110] A plurality of sliding sleeves 225 are disposed on a side of the touch pressure rod 224 away from the contact plate 222 .

[0111] The sliding sleeve 225 is made of elastic material. When the arc-shaped connecting shell 221 rotates, the sliding sleeve 225 inside the arc-shaped connecting shell 221 will contact the surface of the fixed card shell 121 during the rotation process, so that the sliding sleeve 225 is compressed and contracted, and presses the touch pressure rod 224 inward, so that the touch pressure rod 224 squeezes the contact plate 222. A display screen is provided on the outside of the contact plate 222. The number of triggering times of the touch pressure rod 224 can be recorded and displayed through the display screen, thereby recording the number of bandaging circles of the gauze 230.

[0112] This solution has at least the following beneficial effects:

[0113] The bidirectional design of the hemostasis module and the bandaging module makes the device easy to operate, suitable for different limb parts, and does not require special direction settings. The expansion gasket can effectively stop bleeding after inflation, and the air pressure can be accurately controlled by automatic and manual adjustment to ensure rapid and stable hemostasis of the wound while reducing the patient's discomfort. The bandaging module achieves fast and uniform wound bandaging through the coordinated work of the guide component and the winding component. Especially in the case of larger wounds, the two gauze rolls can bandage both sides of the wound at the same time, significantly improving the winding efficiency and saving time. The display screen records the number of gauze windings in real time, providing medical staff with clear bandaging information and enhancing the accuracy and reliability of the operation. The design of this solution improves the efficiency of hemostasis and bandaging, simplifies the operation process, and can be quickly operated in the absence of professional medical personnel. It is suitable for emergency treatment and on-site treatment, and has a high degree of portability and practicality.
