Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to an emergency hemostasis device for upper limb trauma. Background Technology

[0002] In emergency situations involving upper limb traumatic bleeding, common hemostasis methods include pressure hemostasis, elevation of the injured limb, digital artery pressure hemostasis, pressure bandaging, and tourniquet hemostasis. Elevating the injured upper limb, placing the bleeding site above the patient's heart, helps slow the bleeding. Tourniquet hemostasis involves wrapping a thick strip of cloth, towel, or clothing around the injured upper arm as padding, and then applying a tourniquet over the padding. In emergency hemostasis of upper limb traumatic bleeding, it has been found that tourniquet hemostasis combined with elevation of the upper limb has a good hemostatic effect; however, patients may experience fatigue and difficulty sustaining the elevation. Utility Model Content

[0003] The purpose of this invention is to provide an emergency hemostasis device for upper limb trauma. This hemostasis device is based on the tourniquet hemostasis method to bind the upper arm to stop bleeding and assists the patient in raising the injured upper limb, so as to solve the problem mentioned in the background art that patients experience fatigue and difficulty in continuing to raise the injured upper limb.

[0004] This utility model is achieved through the following technical solution:

[0005] An emergency hemostasis device for upper limb trauma, comprising:

[0006] An arc-shaped backrest that can be placed against the patient's lower back and abdomen, with a shoulder strap attached to the top of the arc-shaped backrest for diagonally hanging over the patient's shoulder, thereby suspending the arc-shaped backrest under the armpit;

[0007] A horizontal beam is used to support the patient's elbow. One end of the horizontal beam is fixed to the outer wall of the top of the arc-shaped backrest. When the patient's elbow is bent and forearm is raised, the elbow is supported by the horizontal beam, which makes it easier for the patient to raise the injured upper limb to stop bleeding and reduces upper limb fatigue.

[0008] A tourniquet used to stop bleeding on the upper arm is used to wrap the patient's injured upper arm with padding, and then the tourniquet is tied around the outside of the padding to stop the bleeding.

[0009] The upright pole is fixed at its bottom end to the top surface of the horizontal beam away from the curved backing plate. The top of the upright pole is equipped with a wrist strap for binding the wrist. When the patient's elbow is bent and forearm is raised, and the elbow is supported on the horizontal beam plate, the wrist strap can be used to bind the wrist to prevent the forearm from tilting. This makes it easier to raise the forearm and reduces upper limb fatigue.

[0010] Furthermore, waist belts are connected to the front and rear edges of the bottom of the arc-shaped backrest. When the shoulder straps are draped diagonally over the patient's shoulder and the arc-shaped backrest is suspended under the armpit, the two waist belts can be used to tie the bottom of the arc-shaped backrest to the patient's waist, so that the arc-shaped backrest can be stably attached to the patient's waist and abdomen, reducing the shaking of the arc-shaped backrest during use.

[0011] Furthermore, the curved backrest is made of soft plastic, with shoulder straps slung diagonally over the shoulders and two waist belts tied around the waist, which can pull the curved backrest to bend it so that it can better fit against the patient's waist and abdomen.

[0012] Furthermore, the top surface of the horizontal beam is provided with a support platform for raising and supporting the patient's elbow. Compared to supporting the elbow on the top surface of the horizontal beam, where the elbow tends to be at the same height as the armpit, supporting the elbow on the support platform allows the upper arm to tend to be at the same level as the shoulder, which is higher than the heart.

[0013] Furthermore, the top surface of the support platform is provided with a soft pad, which can improve comfort when the elbow is placed on the support platform.

[0014] Furthermore, a rib is provided between the bottom surface of the horizontal beam plate and the outer wall of the arc-shaped backing plate, which can improve the load-bearing capacity of the horizontal beam plate.

[0015] Furthermore, the support platform is provided with a limit buckle, and a channel is formed between the limit buckle and the top surface of the support platform for the tourniquet to pass through. The limit buckle can be used to restrict the tourniquet and prevent it from falling off the support platform.

[0016] Furthermore, one end of the tourniquet is provided with a loop, and the bottom surface of the other end is provided with a hook and loop fastener. The bottom surface of the tourniquet is provided with a hook and loop fastener between the hook and loop fastener. When the tourniquet is used to bind the upper arm to stop bleeding, one end of the hook and loop fastener of the tourniquet passes through the loop fastener and folds back to form a ring-shaped structure. After tightening, the hook and loop fastener are glued together, which can tighten the upper arm.

[0017] Furthermore, the shoulder strap includes two straps, one end of which is fixed to the top of the arc-shaped backrest and they are spaced apart front and back. The other end of the two straps is provided with a female buckle and a male buckle, and the length of the strap connected to the male buckle is adjustable. When wearing the shoulder strap, the female buckle and the male buckle are inserted. When disassembling, the female buckle and the male buckle are separated, and the arc-shaped backrest can be quickly removed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This hemostatic device combines tourniquet hemostasis with elevation of the injured upper limb in emergency hemostasis of upper limb trauma. It ensures the effectiveness of emergency hemostasis of upper limb trauma. The shoulder strap is diagonally placed on the patient's shoulder to suspend the curved backboard under the armpit. The patient raises the injured upper limb so that the elbow is supported on the horizontal beam. The tourniquet can be tied around the outside of the padding to tightly bind the upper arm for hemostasis. The two wrist straps bind the wrist to prevent the forearm from tilting. It makes it easier to raise the injured upper limb, reduces upper limb fatigue, and makes it easier for the patient to persist. Attached Figure Description

[0026] An emergency hemostatic device for upper limb trauma, such as Figure 1 and Figure 2 As shown, it mainly consists of an arc-shaped backing plate 1, a horizontal beam plate 3, a support platform 4, a tourniquet 9, and a vertical pole 7.

[0027] like Figure 1 and Figure 2 As shown, the arc-shaped backrest 1 is made of soft plastic, including but not limited to PVC, PE, PP and other plastics, so that the arc-shaped backrest 1 has an arc-shaped plate structure in its initial state, which can be bent to fit against the patient's waist and abdomen. The top of the arc-shaped backrest 1 is connected to a shoulder strap 11 for diagonally hanging on the patient's shoulder, so that the arc-shaped backrest 1 can be suspended under the armpit.

[0028] The shoulder strap 11 includes two straps, one end of which is fixed to the top of the arc-shaped backrest 1 and is spaced apart. The other end of the two straps is provided with a female buckle 12 and a male buckle 13 respectively. The length of the strap connected to the male buckle 13 is adjustable. When the shoulder strap is worn, the female buckle 12 and the male buckle 13 are inserted. When disassembling, the female buckle 12 and the male buckle 13 are separated, and the arc-shaped backrest 1 can be quickly removed. When the shoulder strap 11 is worn diagonally on the shoulder, the length of the strap connected to the male buckle 13 can be adjusted to adjust the overall length of the shoulder strap 11, thereby ensuring that the top of the arc-shaped backrest 1 is close to the armpit position.

[0029] like Figure 1 and Figure 2 As shown, waist belts 16 are connected to the front and rear edges of the bottom of the arc-shaped backrest 1. When the shoulder straps 11 are draped diagonally over the patient's shoulder and the arc-shaped backrest 1 is suspended under the armpit, the two waist belts 16 can be used to tie the bottom of the arc-shaped backrest 1 to the patient's waist, so that the arc-shaped backrest 1 can be stably attached to the patient's waist and abdomen, reducing the shaking of the arc-shaped backrest 1 during use.

[0030] When the shoulder strap 11 is slung diagonally over the shoulder and the two waist belts 16 are tied around the waist, they can pull the curved backrest 1 to bend it so that it can better fit against the patient's waist and abdomen. In addition, waist belts can be connected to the front and back edges of the top of the curved backrest 1. The two upper waist belts can be used to tie the top of the curved backrest 1 to the patient's chest. With the upper and lower waist belts tied together, the curved backrest 1 can be stably fitted against the patient's waist and abdomen, reducing the shaking of the curved backrest 1 during use.

[0031] like Figure 1 and Figure 2 As shown, one end of the horizontal beam plate 3 is fixed to the outer side wall of the top of the arc-shaped backing plate 1. The top surface of the horizontal beam plate 3 is provided with a support platform 4 for raising and supporting the patient's elbow. The patient's elbow is bent and the forearm is upward. The elbow is supported by the horizontal beam plate 3, which makes it easier for the patient to raise the injured upper limb to stop bleeding and reduces upper limb fatigue. Compared with supporting the elbow on the top surface of the horizontal beam plate 3, the elbow tends to be at the same level as the armpit. Supporting the elbow on the support platform 4 makes the upper arm tend to be at the same level as the shoulder, which is higher than the heart position.

[0032] like Figure 1 and Figure 2 As shown, the tourniquet 9 is used to stop bleeding on the patient's upper arm. After the patient's injured upper arm is wrapped with padding, the tourniquet 9 is tied around the outside of the padding to stop the bleeding. One end of the tourniquet 9 is provided with a loop 10, and the bottom surface of the other end is provided with a hook and loop fastener 14. The bottom surface of the tourniquet 9 is provided with a hook and loop fastener 15 between the hook and loop fastener 14 and the loop fastener 10. When the tourniquet 9 is used to stop bleeding on the upper arm, one end of the hook and loop fastener 14 of the tourniquet 9 passes through the loop fastener 10 and folds back to form a ring-shaped structure. After tightening, the hook and loop fastener 14 and the hook and loop fastener 15 are glued together to tighten the upper arm.

[0033] The support platform 4 is provided with a limiting buckle 6, which forms a channel between the limiting buckle 6 and the top surface of the support platform 4 for the tourniquet 9 to pass through. The limiting buckle 6 can restrict the tourniquet 9 and prevent it from falling off the support platform 4. When the patient's elbow is supported on the support platform 4 and the tourniquet 9 is tied to the upper arm to stop bleeding, the limiting buckle 6 can also limit the tourniquet and prevent the patient's elbow from slipping off the support platform 4.

[0034] like Figure 1 and Figure 2 As shown, the bottom end of the upright 7 is fixed to the top surface of the horizontal beam plate 3 away from the arc-shaped backing plate 1. The top end of the upright 7 is provided with a wrist strap 8 for binding the wrist. When the patient's elbow is bent and forearm is raised, and the elbow is supported on the horizontal beam plate 3, the wrist strap 8 can be used to bind the wrist to prevent the forearm from tilting. This makes it easier to raise the forearm and reduces upper limb fatigue.

[0035] Preferably, in this embodiment, such as Figure 1 As shown, the top surface of the support platform 4 is provided with a soft pad 5, which can improve comfort when the elbow is placed on the support platform 4.

[0036] Preferably, in this embodiment, such as Figure 1 As shown, a rib plate 2 is provided between the bottom surface of the horizontal beam plate 3 and the outer wall of the arc-shaped backing plate 1, which can improve the load-bearing capacity of the horizontal beam plate 3.

[0037] The method of using this hemostatic device is as follows:

[0038] In emergency situations involving upper limb trauma and bleeding, after unfastening the female buckle 12 and male buckle 13, place the curved backrest 1 under the armpit on the side of the injured upper limb. Connect the two straps of the shoulder strap 11 alongside the female buckle 12 and male buckle 13, so that the shoulder strap 11 is draped diagonally over the patient's shoulder, thus suspending the curved backrest 1. Then, tie the two waist belts 16 around the patient's waist, thus securing the bottom end of the curved backrest 1 to the patient's waist. This ensures the curved backrest 1 is stably positioned against the patient's lower back and abdomen, reducing swaying during use. After wrapping the padding around the patient's injured upper arm, elevate the injured upper limb so that the hand... The elbow is supported on the support platform 4. The tourniquet 9 is tied around the outside of the padding to tightly bind the upper arm for hemostasis. The wrists are tied with two wrist straps 8 to prevent the forearm from tipping over, making it easier to raise the forearm and reducing upper limb fatigue. This hemostatic device combines the tourniquet 9 method of binding the injured upper arm for hemostasis with the method of elevating the injured upper limb for hemostasis. It can ensure the hemostasis effect of upper limb trauma. The support platform 4 of this hemostatic device can support the patient's raised injured upper limb. The wrists are tied with wrist straps 8 to prevent the forearm from tipping over, making it easier to raise the injured upper limb, reducing upper limb fatigue, and making it easier for the patient to persist.
