Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a hemostatic device. Background Technology

[0002] In related fields, tourniquets are commonly used for stopping bleeding from external injuries. Common tourniquets include traditional triangular bandages, rubber tubing, elastic bandages, as well as newer ones such as snap-on tourniquets and pneumatic tourniquets. However, ordinary tourniquets achieve hemostasis by compressing a single main blood vessel (such as the femoral artery or brachial artery), and are only suitable for emergency treatment of arterial and venous bleeding in the head, face, neck, and limbs. In the abdomen, there is no single main blood vessel that can be targeted for compression, and the abdominal area is large and the abdominal tissue is relatively soft. Ordinary tourniquets are difficult to apply pressure evenly, which may lead to insufficient local compression, resulting in continued bleeding, or excessive compression, which may lead to the risk of damage to deep organs.

[0003] Therefore, how to achieve effective hemostasis in the abdomen has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a hemostatic device for achieving effective hemostasis of the abdomen.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A hemostatic device, comprising:

[0007] A waist trainer, used to wrap tightly around the injured area;

[0008] At least one hemostatic balloon, which is movably disposed on the waist belt and is used to be inserted into an abdominal wound;

[0009] A pressure airbag is connected to the hemostatic balloon via a connecting trachea. The pressure airbag is used to inflate the hemostatic balloon so that the hemostatic balloon expands to fit snugly against the abdominal wound.

[0010] Optionally, in the above-mentioned hemostatic device, the waist belt is provided with a track and a movable seat that moves along the track, and the hemostatic balloon is mounted on the movable seat.

[0011] Optionally, in the above-mentioned hemostasis device, the movable seat includes a sliding part and a connecting part disposed on the sliding part. The sliding part is provided with an air inlet for connecting to the connecting air tube, and the connecting part is provided with an air outlet communicating with the air inlet. The opening of the hemostasis balloon is sleeved on the connecting part, and the air outlet is located inside the hemostasis balloon.

[0012] Optionally, in the above-mentioned hemostatic device, the hemostatic balloon has a flange at the stop opening, and the connecting part has a groove that mates with the flange.

[0013] Optionally, in the above-mentioned hemostatic device, the sliding part is provided with a sliding hole through which the track can pass.

[0014] Optionally, in the above-mentioned hemostatic device, the outer wall of the hemostatic balloon is provided with multiple protrusions.

[0015] Optionally, in the above-mentioned hemostatic device, the connecting air tube is connected to a pressure display device with an alarm function via a pressure three-way valve. When the air pressure reaches a predetermined value, the pressure display device issues an alarm reminder.

[0016] Optionally, in the above-mentioned hemostatic device, a tightening band is provided on the side of the waist belt away from the hemostatic balloon, and the tightening band is provided with a buckle for connection.

[0017] Optionally, in the above-mentioned hemostatic device, at least one rotary pressure device may be movably provided on the tightening band, the rotary pressure device being used to tighten the hemostatic balloon.

[0018] Optionally, in the above-mentioned hemostasis device, there are two hemostasis balloons, and the connecting trachea is connected to the two hemostasis balloons respectively through a dual-channel three-way valve.

[0019] The hemostatic device provided in this application involves wrapping the injured area tightly with a waist belt, while simultaneously moving a hemostatic balloon, movably mounted on the waist belt, to the abdominal wound and inserting it into the wound. A pressure balloon is then used to inflate the hemostatic balloon, causing it to expand and adhere tightly to the abdominal wound, thereby achieving hemostasis through pressure from the inside out. As can be seen from the above example, the hemostatic device provided in this application, by injecting the hemostatic balloon into the abdominal wound and inflating it to make it adhere tightly to the wound, can effectively stop bleeding from the abdominal wound.

Detailed Implementation

[0027] The core of this application is to provide a hemostatic device to achieve effective hemostasis in the abdomen.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In related fields, especially when soldiers are wounded on the battlefield, tourniquets are commonly used to stop bleeding from external injuries. Common tourniquets include traditional triangular bandages, rubber tubing, elastic bandages, as well as newer ones such as buckle tourniquets and pneumatic tourniquets. However, ordinary tourniquets achieve hemostasis by compressing a single main blood vessel (such as the femoral artery or brachial artery), and are only suitable for emergency treatment of arterial and venous bleeding in the head, face, neck, and limbs. In the abdomen, there is no single main blood vessel for targeted compression, and the abdominal area is large and the abdominal tissue is relatively soft. Ordinary tourniquets are difficult to apply pressure evenly, which may lead to insufficient local compression and continued bleeding, or excessive compression and risk of damage to deep organs.

[0030] Therefore, such as Figure 1 As shown in the figure, this application discloses a hemostatic device, including a waist belt 10, a pressure bladder 30, and at least one hemostatic balloon 20. By injecting the hemostatic balloon 20 into the abdominal wound and inflating it with pressure, the hemostatic balloon 20 expands to fit tightly against the abdominal wound, thereby achieving effective hemostasis of the abdominal wound.

[0031] The following will combine Figures 1 to 4 The hemostatic device disclosed in the embodiments of this application will be explained and described in detail.

[0032] like Figure 1 As shown, the waist-cinching belt 10 can be attached via Velcro to tightly wrap the patient's injured area. Simultaneously, the hemostatic balloon 20 is movably mounted on the waist-cinching belt 10, allowing it to be moved to the abdominal wound and inserted into it. Furthermore, the pressure-inflating cuff 30 is connected to the hemostatic balloon 20 via a connecting tube 40. The pressure-inflating cuff 30 inflates the hemostatic balloon 20 until it fits snugly against the abdominal wound, thereby achieving compression hemostasis from the inside out.

[0033] The hemostatic balloon 20 can be a velvety silicone balloon, and at least one hemostatic balloon 20 can be used, that is, there can be one hemostatic balloon 20, or there can be two or more hemostatic balloons 20. When there is a unilateral abdominal injury, i.e., only one abdominal wound, a single hemostatic balloon 20 can be used. The balloon 20 is moved to the location of the abdominal wound and inserted into it. The balloon 20 is then inflated by manually pressing the pressure bag 30 until it fits snugly against the abdominal wound, thus achieving hemostasis from the inside out. When there is a penetrating wound or multiple wounds in the abdomen, two or more hemostatic balloons 20 can be used. Each balloon 20 is moved to the location of its respective abdominal wound and inserted into it. The balloon 20 is then inflated by manually pressing the pressure bag 30 until it fits snugly against the abdominal wound, thus achieving hemostasis from the inside out for each abdominal wound.

[0034] In some embodiments, such as Figure 1 As shown, the waist belt 10 can be equipped with a track 11 and a movable seat 12 that moves along the track 11. The hemostatic balloon 20 can be installed on the movable seat 12 so that the movable seat 12 can move along the track 11, thereby adjusting the position of the hemostatic balloon 20. The track 11 and the waist belt 10 can be connected by Velcro so that the movable seat 12 and the hemostatic balloon 20 on the movable seat 12 can be attached and detached in different scenarios.

[0035] In some embodiments, such as Figure 4 As shown, the movable seat 12 may include a sliding part 121 and a connecting part 122 disposed on the sliding part 121. The sliding part 121 has a through-hole 1212 in its side wall, allowing the track 11 to pass through, so that the sliding part 121 can slide along the track 11. Simultaneously, an air inlet 1211 is provided in the side wall of the sliding part 121, which can be connected to the connecting air tube 40. An air outlet 1221 communicating with the air inlet 1211 is provided on the side of the connecting part 122 away from the sliding part 121, so that the opening of the hemostatic balloon 20 can be fitted onto the connecting part 122, and the air outlet 1221 is located inside the hemostatic balloon 20, thereby ensuring that the hemostatic balloon 20 can be pressurized and inflated by the pressurized air bag 30.

[0036] Of course, the track 11 can also adopt a T-shaped cross section, and the sliding part 121 extends toward the side close to the track 11 to form a C-shaped groove or a T-shaped groove, so that the sliding part 121 of the movable seat 12 can move along the track 11. This is not limited here.

[0037] In some embodiments, such as Figure 3 and Figure 4 As shown, the stop opening of the hemostatic balloon 20 can be folded outward to form a flange 21, and the connecting part 122 is provided with a groove 1222 that cooperates with the flange 21, thereby preventing the hemostatic balloon 20 from falling off when it is pressurized and expanded.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, multiple protrusions 22 can be provided on the outer wall of the hemostatic balloon 20. The protrusions 22 can be evenly distributed at intervals or unevenly distributed at intervals. The friction between the hemostatic balloon 20 and the abdominal wound can be increased by the protrusions 22, preventing the hemostatic balloon 20 from falling out of the wound.

[0039] In some embodiments, such as Figure 1As shown, two hemostatic balloons 20 can be used, and the connecting endotracheal tube 40 can be connected to the air inlets 1211 on the movable seats 12 of the two hemostatic balloons 20 respectively through a dual-channel three-way valve 43. When there is a unilateral abdominal injury, that is, only one abdominal wound, the dual-channel three-way valve 43 can be adjusted to allow air to enter from one side, thereby ensuring that one hemostatic balloon 20 inflates to fit tightly against the abdominal wound, thus achieving the purpose of applying pressure to stop bleeding from the inside out.

[0040] In some embodiments, such as Figure 1 As shown, a pressure display device 42 with an alarm function can be connected to the air tube 40 via a three-way pressure valve 41. The pressure display device 42 can display the pressure value in real time. When the air pressure reaches a predetermined value, the pressure display device 42 can emit a buzzer alarm sound. It should be noted that the predetermined value is a pressure value preset by the operator; at this pressure value, the hemostatic balloon 20 can effectively stop bleeding from the abdominal wound.

[0041] In some embodiments, such as Figure 2 As shown, a tightening band 13 is provided on the side of the waist belt 10 away from the hemostatic balloon 20, and a buckle 131 is provided on the tightening band 13. By connecting the buckle 131 of the tightening band 13, the waist belt 10 can be tightened so that the waist belt 10 wraps tightly around the injured area and prevents the hemostatic balloon 20 from falling out of the abdominal wound.

[0042] In some embodiments, such as Figure 2 As shown, at least one rotary pressure device 50 can also be movably provided on the tightening band 13, so that the rotary pressure device 50 can move along the tightening band 13, thereby adjusting the rotary pressure device 50 to the position corresponding to the hemostatic balloon 20 and tightening the hemostatic balloon 20 to prevent the hemostatic balloon 20 from dislodging from the abdominal wound when it is pressurized and inflated. One rotary pressure device 50 can be used; when the abdominal wound is a penetrating wound, the rotary pressure device 50 only needs to be moved to the position of the hemostatic balloon 20 corresponding to the more irregular part of the wound to tighten the hemostatic balloon 20. Two or more rotary pressure devices 50 can also be used to tighten each hemostatic balloon 20 separately.

[0043] In some embodiments, the knob pressurizing device 50 may include a threaded seat and a knob. The threaded seat is movable along the tensioning band 13 and has a threaded hole, while the knob has a threaded portion that mates with the threaded hole, so that by turning the knob, the end of the knob can be pressed against the hemostatic balloon 20.

[0044] The hemostatic device disclosed in this application is simpler to operate and can achieve efficient and rapid hemostasis of abdominal wounds. It is further connected via Velcro to the waistband 10 and buckles 131 to the tightening strap 13, effectively preventing loosening. Simultaneously, a pressure display device 42 with an alarm function can display the pressure value in real time and provide overpressure alerts. The inflation volume can be adjusted according to the real-time pressure value to regulate the pressure. Furthermore, the pressure value can be flexibly adjusted as needed, and the patient can also adjust the inflation pressure according to the comfort level of the bandage, improving patient comfort and effectively avoiding serious complications such as local tissue necrosis and peripheral circulatory disorders caused by excessive pressure.
