Description

A wound hemostasis and pressure device for preventing limb blood flow blockage

Technical Field

The invention belongs to the technical field of medical devices, and in particular relates to a wound hemostasis and pressure device for preventing limb blood supply blockage.

Background technique

Hemostasis refers to the method of stopping blood from continuing to flow out of blood vessels after bleeding occurs. Timely and effective hemostasis on the spot is an important technology to save lives, reduce mortality, and gain further treatment time for patients.

At present, temporary hemostasis at the first aid site usually requires tying the proximal end of the patient's wound with a tether to stop bleeding, or the operator places gauze on the wound to press and stop bleeding. However, the above methods are prone to cause limb damage to the patient due to long-term blocking of blood flow. The operation time is relatively long. Therefore, the inventor hopes to set up an inflatable pressurized structure that does not affect blood circulation and quickly presses the wound to stop bleeding.

Summary of the invention

The technical problem to be solved by the present invention is that the current pressing hemostasis method will block blood flow over a long period of time, causing damage to the patient's limbs due to ischemia. Therefore, the present invention provides a hemostasis device that can ensure that the blood flow of part of the pressed limb is normal while pressing hemostasis, thereby avoiding limb ischemia damage.

The present invention is a wound hemostasis and pressure device for preventing limb blood supply blockage, comprising:

Hemostatic balloon, used to compress the bleeding site to stop bleeding;

A fixing belt connected to the hemostatic balloon is wrapped around the patient's body so that the hemostatic balloon is pressed tightly against the bleeding site;

The blood supply balloons are distributed at intervals on the fixing belt and connected to the fixing belt, so that the compressed body part of the patient has partial normal blood supply.

The present invention wraps a fixing belt around the patient's body so that the hemostatic balloon is tightly pressed against the bleeding hole to stop bleeding; the blood supply balloons are distributed at intervals so that one part of the patient's body contacts the blood supply balloons and the other part is located between the blood supply balloons, thereby ensuring that a part of the blood vessels is not compressed and has normal blood supply, thereby avoiding tissue necrosis.

In some embodiments of the present application, the hemostatic balloon is an elliptical column structure when in use, so that the hemostatic balloon exerts sufficient pressure on the bleeding hole. The side of the elliptical column hemostatic balloon in contact with the bleeding hole is an arc surface, which exerts greater pressure, thereby effectively playing the function of pressing to stop bleeding.

In some embodiments of the present application, an inflatable balloon is further included, which is connected to the hemostatic balloon through an inflation tube. During use, the inflatable balloon is squeezed to inflate the hemostatic balloon so that the hemostatic balloon is filled.

In some embodiments of the present application, the inflation tube is provided with an air deflation valve, and during use, the gas in the hemostatic balloon is discharged through the air deflation valve, so that the hemostatic balloon is no longer inflated.

In some embodiments of the present application, the blood supply balloons are distributed on the fixing belt at intervals, and the blood supply balloons are arranged opposite to the hemostatic balloons, so that the bleeding port of the patient contacts the hemostatic balloons, and the opposite side of the bleeding port contacts the blood supply balloons. During use, the bleeding port of the patient faces the hemostatic balloon, and the hemostatic balloon presses the bleeding port to stop bleeding; the filled hemostatic balloon squeezes the patient's body, and the blood supply balloons are arranged at intervals, and some blood vessels are located at the intervals between the blood supply balloons, so that some blood supply can be kept normal and tissue ischemia damage can be avoided.

In some embodiments of the present application, a mounting belt is further included to fix the blood supply balloon. The inflated blood supply balloon is fixedly connected to the mounting belt in the standby state, and the mounting belt is mounted on the fixing belt in the use state. This arrangement facilitates the quick installation of the blood supply balloon on the fixing belt through the mounting belt, which is efficient and time-saving.

Preferably, one side of the mounting belt is connected to the blood supply balloon, and the other side is detachably fixedly connected to the fixing belt. In the standby state, the blood supply balloon is located on the mounting belt, and when in use, the mounting belt is mounted on the fixing belt.

In some embodiments of the present application, the mounting belt and the fixing belt are bonded by Velcro, the mounting belt is provided with Velcro surface A, and the fixing belt is provided with Velcro surface B. When in use, the mounting belt is attached to the fixing belt.

In some embodiments of the present application, the fixing belt is a belt-like structure with a regular shape.

Preferably, the fixing belt is provided with a fixing piece for limiting the position of the free end of the fixing belt so that the fixing belt is fastened to the patient.

In some embodiments of the present application, a pressure sensor is provided on the side of the hemostatic balloon in contact with the patient's limbs, for real-time monitoring of the pressure exerted by the hemostatic balloon on the patient's limbs.

Preferably, it also includes a pressure display, which is connected to the sensor data and displays the pressure value detected by the sensor.

Beneficial effects of the present invention:

(1) By wrapping the fixation belt around the patient, the hemostatic balloon presses the bleeding site, thereby achieving the effect of pressing and stopping bleeding;

(2) Under the squeezing force of the hemostatic balloon, body parts other than the bleeding site are also squeezed. However, since the blood supply balloons are distributed at intervals, the body parts corresponding to the intervals can maintain normal blood supply to avoid tissue necrosis.

The method of using the present invention:

1. Install the blood supply balloon on the mounting belt, and then install the mounting belt on the fixing belt; or, directly install the mounting belt with the blood supply balloon on the fixing belt;

2. Wrap the fixation belt around the patient's limb with bleeding, align the hemostatic balloon with the bleeding hole, inflate the hemostatic balloon by inflating the balloon, so that the hemostatic balloon is filled, and the hemostatic balloon presses the bleeding hole to stop bleeding;

3. After hemostasis is completed, the gas in the hemostatic balloon is slowly discharged into the air through the deflation valve to avoid swelling caused by instantaneous pressure release on the limbs;

4. Remove the fixation belt from the patient and disinfect it for next use.

The present invention wraps a fixing belt 1 around the patient's body so that the hemostatic balloon 2 is pressed tightly against the bleeding site to stop the bleeding; the blood supply balloons 4 are distributed at intervals so that one part of the patient's body is in contact with the blood supply balloons 4, and the other part is located between the blood supply balloons 4, thereby ensuring that a part of the blood vessels are not compressed and have normal blood supply, thereby avoiding tissue necrosis.

In some embodiments of the present application, the hemostatic balloon 2 is a capsule-like structure with a regular shape.

As shown in Figures 1 to 3, in some embodiments, the hemostatic balloon 2 is an elliptical column structure in use, so that the hemostatic balloon 2 has sufficient pressure on the bleeding hole. The side of the elliptical column-shaped hemostatic balloon 2 that contacts the bleeding hole is an arc surface, which has a large pressure, thereby effectively playing the role of pressing to stop bleeding.

In some embodiments, the hemostatic balloon 2 is integrally formed with the fixing belt 1, and the fixing belt 1 is made of an airtight material. When in use, the hemostatic balloon 2 is inflated, and the corresponding part of the fixing belt 1 is also inflated, which plays a role of pressing and stopping bleeding at the bleeding site.

In other embodiments, the fixing belt 1 is a double-layer structure, and the hemostatic balloon 2 is located between the double-layer structure, and the double-layer structure can limit the position of the hemostatic balloon 2. The double-layer structure can accommodate the hemostatic balloon 2 in a filled state. During the inflation process, the double-layer structure is filled with the filling of the hemostatic balloon 2. After the hemostatic balloon 2 is fully filled, the double-layer structure is attached to the hemostatic balloon 2. During use, the surface of the double-layer structure in contact with the patient's skin is smooth and wrinkle-free, avoiding causing pressure marks on the patient's skin.

As shown in Figures 4 to 7, in other embodiments of the present application, the hemostatic balloon 2 is an arc-shaped sac-like structure, and a pressing capsule 21 is provided on the hemostatic balloon 2. The pressing capsule 21 is connected to the hemostatic balloon 2, and the pressing capsule 21 is filled as the hemostatic balloon 2 is filled.

Specifically, the pressing capsule 21 is a protruding structure with a regular shape. Preferably, the pressing capsule 21 is a spherical structure.

In some other embodiments, the pressing bag 21 is a soft bag body. When the wound is a surface wound or a multi-point explosion injury, the side of the soft bag body that contacts the skin is a deformable bag wall, and the other sides cannot be deformed; or, a limiting structure is provided to limit the soft bag body; a bulging opening is provided on the side of the limiting structure that contacts the skin for the soft bag body to deform and bulge.

Specifically, the limiting structure includes a cavity, the soft capsule is limited in the cavity, and a bulging opening facing the bleeding point of the skin is arranged on the side of the cavity contacting the skin. The limiting structure is set to any shape, and the surface area of its cross section is not less than 50cm². This area setting can ensure a sufficiently large contact area. The surface area of a single bulging opening is not less than 5cm². This setting can ensure bulging hemostasis of a single bleeding point.

The surface area of the bulging opening is smaller than the overall area of the side of the limiting structure that contacts the skin; this arrangement can prevent the soft bladder from falling off during the inflation process.

The bulge opening is disposed at a central position on the skin-contacting side of the defining structure.

A position constraint structure is also provided for constraining the defined structure at the bleeding position.

The position restraining structure is a fixing belt 1 which can bind the limiting structure to the bleeding position.

As shown in Fig. 6-Fig. 7, or, when the bleeding is in the limbs, the position restraining structure is a hard sleeve structure;

The hard sleeve is a combined sleeve, preferably a combination of 2-4 equally divided parts.

The limiting structure and the hard sleeve are provided with corresponding combination structures, such as the inner side of the hard sleeve and the limiting structure are provided with a corresponding pattern sticker. Alternatively, the inner side of the hard sleeve is a smooth curved surface, and an easy-tear adhesive layer is provided on the limiting structure, and the hard sleeve and the limiting structure are combined by the easy-tear adhesive layer; through the above two arrangements, the combination position can be adjusted according to the bleeding point position.

The limiting structure is made of a non-elastic soft material, preferably a non-elastic textile material. This arrangement can ensure that the limiting structure changes with the position of the bleeding skin.

The limiting structure may be a rectangular structure, and the rectangular structure may surround a portion of the limb.

A deformable soft capsule is arranged in the bleeding cavity or the skin on the body surface, and it is inflated by the inflatable balloon 3 during use, so that it deforms and adapts in shape according to the skin surface and the cavity shape; it can effectively fill the cavity or fit the skin, and the soft capsule will preferentially deform and fit toward the concave part, and continuously maintain the pressurization of the fitting state during the continuous inflation process, so as to achieve the purpose of pressurizing the bleeding point to stop bleeding.
