Description

Technical Field

[0001] The invention belongs to the technical field of surgical wound treatment and relates to a trauma hemostasis device for emergency department. Background Art

[0002] The emergency department or emergency medical center is the department with the most critically ill patients, the most diseases, and the heaviest rescue and management tasks in the hospital. It is also the only way for all emergency patients to be admitted for treatment. For some patients with body surface trauma that require emergency hemostasis, hemostasis work is required to reduce blood loss.

[0003] At present, when stopping bleeding for patients, in most cases, a rubber tube is used for hemostasis, that is, the rubber tube is tied to the proximal end of the patient's wound to achieve compression hemostasis. However, during the hemostasis process, the patient's wound is exposed to the air, which is susceptible to infection and the effect is poor. For this reason, there are also occasions where a hemostatic device is used for hemostasis. The device can cover the proximal end of the patient's wound and isolate the wound from the outside world, effectively preventing wound infection. However, when sending the patient to a doctor for further treatment, it is often necessary to remove the hemostatic device first, which brings inconvenience to the treatment. Summary of the invention

[0004] In view of this, the present invention provides a trauma hemostasis device for emergency department.

[0005] The technical implementation scheme of the present invention is: a trauma hemostasis device for emergency department, including a proximal end strap, a Velcro, a shielding frame, a distal end strap, an isolation membrane and a locking mechanism, the proximal end strap is connected to the shielding frame, the shielding frame is connected to the distal end strap, the proximal end strap and the distal end strap are both provided with Velcro, a notch is opened in the middle of the shielding frame, an isolation membrane is bonded to the notch, and a locking mechanism is provided on the proximal end strap.

[0006] In one embodiment, the locking mechanism includes a locking frame, a locking frame and an elastic member, the proximal end strap is connected to the locking frame, the locking frame is slidably connected to the locking frame, an elastic member is connected between the locking frame and the locking frame, and a plurality of notches are evenly spaced at the bottom of the locking frame so that the bottom of the locking frame forms a claw-shaped structure, thereby increasing the friction force when the locking frame contacts the proximal end strap.

[0007] In one of the embodiments, the lower portion of the locking frame is inclined.

[0008] In one of the embodiments, an elastic barrier pad is further included. The bottom of the shielding frame is connected to an elastic barrier pad capable of isolating the patient's wound from other locations.

[0009] In one of the embodiments, a fixing mechanism is also included, which includes a strip-shaped fixed air bag and a connecting air tube. A plurality of strip-shaped fixed air bags are evenly spaced and connected to the bottom of the proximal end strap. A connecting air tube is connected between the left sides of the plurality of strip-shaped fixed air bags. A gas injection port is provided on the connecting air tube for injecting gas into the connecting air tube and the strip-shaped fixed air bag.

[0010] In one of the embodiments, an isolation block is further included. The isolation block is connected to the proximal end strap. When the proximal end strap is wound, the isolation block can press the position where the strip-shaped fixed airbag contacts the proximal end strap.

[0011] In one of the embodiments, a dosing mechanism is also included, which includes a liquid storage bag, a spray pipe, and a pressure valve. Liquid storage bags are embedded on both sides of the locking frame. The bottom of the liquid storage bag is connected to the spray pipe. The liquid storage bag is filled with disinfectant liquid. The spray pipe passes through the locking frame and extends into the notch of the locking frame. A pressure valve is provided at the spray pipe.

[0012] In one of the embodiments, a timer is further included, and the timer is installed on the proximal end strap.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a proximal end bandage, a distal end bandage and a shielding frame to bind the proximal end and the distal end around the wound to stop bleeding. At the same time, the wound can be covered with an isolation membrane to prevent impurities from contaminating the wound and causing wound infection. When treatment is needed, it is only necessary to tear off the isolation membrane, which is more convenient during treatment.

[0014] 2. When binding the proximal end of the patient's wound, the present invention can assist the binding operation by inflating the strip-shaped fixing airbag, and the elasticity of the strip-shaped fixing airbag can reduce the discomfort caused to the patient during the fixing process, making the fixing process more comfortable.

[0015] 3. After hemostasis is completed, the present invention can press the liquid storage bag to spray the disinfectant liquid on the patient's body surface through the spray tube to assist in disinfection and avoid wound infection. In the process of squeezing the liquid storage bag 101, the gas can also be squeezed into the elastic barrier pad 7 to increase the air pressure in the elastic barrier pad 7, thereby preventing blood from flowing out and assisting in hemostasis.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0028] A trauma hemostasis device for emergency department use, such as Figure 1-Figure 6 As shown, it includes a proximal end strap 1, a Velcro 2, a shielding frame 3, a distal end strap 4, an isolation membrane 5 and a locking mechanism, the front side of the proximal end strap 1 is connected to the shielding frame 3, the front side of the shielding frame 3 is connected to the distal end strap 4, the proximal end strap 1 and the distal end strap 4 are both provided with Velcro 2, the Velcro 2 is used to bond the ends of the proximal end strap 1 and the distal end strap 4 together when the proximal end strap 1 and the distal end strap 4 are wound, so as to fix the proximal end strap 1 and the distal end strap 4, a notch is opened in the middle of the shielding frame 3, an isolation membrane 5 is bonded to the notch, and a locking mechanism is provided on the proximal end strap 1.

[0029] like Figure 2-Figure 6 As shown, the locking mechanism includes a locking frame 61, a locking frame 62 and an elastic member 63. The locking frame 61 is connected to the left side of the proximal end strap 1. The locking frame 62 is slidably connected inside the locking frame 61. The locking frame 62 can slide up and down along the locking frame 61. An elastic member 63 is connected between the locking frame 62 and the locking frame 61. The elastic member 63 is a pressure spring. A plurality of notches 64 are evenly spaced at the bottom of the locking frame 62, so that the bottom of the locking frame 62 forms a claw The locking frame 62 has a shaped structure, which increases the friction force when the locking frame 62 contacts the proximal end strap 1. When the proximal end strap 1 is wound around the patient's arm, the tail end of the proximal end strap 1 can pass through the locking frame 61 and the lower part of the locking frame 62, and under the action of the elastic member 63, the locking frame 62 can lock the proximal end strap 1 to prevent the proximal end strap 1 from returning to its original position. The lower left part of the locking frame 62 is inclined so that when the proximal end strap 1 passes through, it can squeeze the locking frame 62 upward through the inclined position of the locking frame 62.

[0030] When it is necessary to stop bleeding from a wound, the device can be used. When in use, the proximal end bandage 1 is placed on one side of the proximal end of the patient's wound, and the proximal end bandage 1 is wrapped around the patient's wound to help the limbs near the proximal end, thereby compressing the blood vessels and preventing blood from flowing out, so as to stop bleeding. When the proximal end bandage 1 is wrapped, the end of the proximal end bandage 1 passes through the inclined surfaces of the locking frame 61 and the locking frame 62, thereby squeezing the locking frame 62 to move upward, and the elastic member 63 is compressed. After the proximal end bandage 1 is wrapped, the locking frame 62 presses the proximal end under the action of the elastic member 63. The end strap 1 can prevent the proximal end strap 1 from being unfastened, and the Velcro 2 can also assist in fixing the proximal end strap 1. After the proximal end strap 1 is tied, the distal end strap 4 is tied to one side of the distal end of the wound. At this time, the entire shielding frame 3 covers the patient's wound, and the patient's wound is located at the notch position of the shielding frame 3, thereby completing the hemostasis work for the patient. When the patient's wound needs to be treated, only the isolation film 5 needs to be torn off, and the patient's wound can be treated through the notch of the shielding frame 3. There is no need to remove the entire hemostasis device, which is more convenient when treating the wound.

[0031] like Figure 7 As shown, an elastic barrier pad 7 is also included. The bottom of the shielding frame 3 is connected to the elastic barrier pad 7. The elastic barrier pad 7 can isolate the patient's wound from other positions. When the device is tied around the patient's wound to stop bleeding, the elastic barrier pad 7 can press the patient's wound, thereby isolating the patient's wound and preventing impurities from contacting the patient's wound and affecting the patient's wound.

[0032] like Figure 4 , Figure 7 and Figure 8 As shown, a fixing mechanism is also included, and the fixing mechanism includes a strip-shaped fixing air bag 81 and a connecting air tube 82. A plurality of strip-shaped fixing air bags 81 are evenly spaced and connected to the bottom of the proximal end bandage 1. A connecting air tube 82 is connected between the left sides of the plurality of strip-shaped fixing air bags 81. A gas injection port 83 is provided on the front side of the connecting air tube 82 for injecting gas into the connecting air tube 82 and the strip-shaped fixing air bag 81, so that the strip-shaped fixing air bag 81 expands to press and fix the patient's hand.

[0033] When the proximal band 1 is tied to the proximal side of the patient's wound, gas can be injected into the connecting air tube 82 through the gas injection port 83, so that the strip-shaped fixed air bag 81 expands to compress the blood vessels at the proximal end of the patient's wound to block blood circulation. The elasticity of the strip-shaped fixed air bag 81 can reduce the discomfort caused by the patient when using it.

[0034] like Figure 4 , Figure 7 and Figure 8 As shown, an isolation block 9 is also included. The isolation block 9 is connected to the left side of the proximal end strap 1. When the proximal end strap 1 is wound, the isolation block 9 can press the position where the strip-shaped fixed airbag 81 contacts the proximal end strap 1, thereby isolating the two sides of the strip-shaped fixed airbag 81. At this time, injecting gas into the strip-shaped fixed airbag 81 can only fill the separated position of the strip-shaped fixed airbag 81, and the separated position just surrounds the patient's arm, thereby achieving the effect of saving gas.

[0035] like Fig. 9 and Fig.10 As shown, a drug delivery mechanism is also included, which includes a liquid storage capsule 101, a drug spraying pipe 102, and a pressure valve 103. The liquid storage capsule 101 is embedded on both sides of the left and right sides of the locking frame 61. The bottom of the liquid storage capsule 101 is connected to the drug spraying pipe 102. The liquid storage capsule 101 is filled with disinfectant liquid. The drug spraying pipe 102 passes through the locking frame 61 and extends into the notch of the locking frame 61, so that the disinfectant liquid inside the squeezer of the liquid storage capsule 101 can be injected into the notch through the drug spraying pipe 102 to disinfect the patient's wound. The pressure valve 103 is provided at the drug spraying pipe 102.

[0036] After using the present device for hemostasis, the liquid storage capsule 101 can also be pressed to inject the disinfectant liquid in the liquid storage capsule 101 into the elastic barrier pad 7 through the spray tube 102, so that the disinfectant liquid contacts the patient's wound, and the patient's wound is disinfected to avoid wound infection. At the same time, in the process of squeezing the liquid storage capsule 101, the disinfectant liquid is also squeezed into the elastic barrier pad 7, which can also increase the hydraulic pressure in the elastic barrier pad 7, thereby preventing blood from flowing out and assisting in hemostasis.

[0037] like Figure 1 As shown, a timer 11 is also included. The proximal end bandage 1 is equipped with the timer 11. After the bandaging process is completed, the timer 11 can be pressed to count the time, and then the patient can be sent to the hospital for wound treatment. The doctor can then better judge the condition of the wound by observing the time of the timer 11.

[0038] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
