Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for improving the limb microcirculation of shock patients. Background Technique

[0002] In a shock state, the total effective circulating blood volume of a patient decreases sharply, resulting in insufficient tissue perfusion. Especially, the microcirculation is damaged, which will further exacerbate tissue ischemia and hypoxia, thereby causing symptoms such as limb numbness, coldness, and pain. In severe cases, it may even lead to multiple organ dysfunction and even failure. Therefore, maintaining a good microcirculation state is crucial for maintaining good health.

[0003] Currently, when improving the microcirculation of patients, an inflatable airbag is put on the lower limbs of the patient, and a pneumatic pump is used to periodically apply and release pressure to the lower limbs of the patient to promote the return of venous blood in the lower limbs and reduce blood stasis, thereby preventing the formation of deep vein thrombosis. However, when using the above method to improve the microcirculation of the lower limbs, due to the poor microcirculation of shock patients, it is difficult to provide the corresponding temperature for the extremities. The extremities are cold, and the blood vessels will naturally contract to reduce heat loss, resulting in an increase in vascular resistance and a decrease in blood flow. And only by pressurizing and decompressing the lower limbs, it is impossible to heat the extremities according to the usage requirements, the microcirculation improvement effect is poor, the recovery efficiency is low, and other heat preservation measures are needed to keep the extremities within an appropriate temperature range, which is inconvenient to use. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrative purposes of this application and not for limiting the scope of this application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0025] Embodiment: A device for improving the limb microcirculation of shock patients, as Figures 1 - 4 shown, includes an air pump 1, an air pipe 2, a bracket 3, a heating frame 4, a heating wire 41, an inflatable inner bladder 72 and a limiting component. The two inflatable inner bladders 72 are symmetrically arranged front and back. The inflatable inner bladder 72 is in the shape of a sock. The right sides of the tops of the two inflatable inner bladders 72 are respectively communicated with one end of four air pipes 2. The other ends of the air pipes 2 are respectively communicated with the air outlets on the left side of the air pump 1. A bracket 3 is placed between the air pump 1 and the inflatable inner bladder 72. The front and back sides of the upper part of the bracket 3 are symmetrically and fixedly connected with heating frames 4. The inner wall of the heating frame 4 is circumferentially fixedly connected with a heating wire 41. The heating wire 41 is in a ring shape. A limiting component is arranged on the heating frame 4. The warm air device composed of the bracket 3, the heating frame 4, the heating wire 41 and the limiting component can heat the compressed air flowing through the air pipe 2, so as to achieve the effect of warming the limb ends.

[0026] As Figure 2 and Figure 4 shown, the limiting component includes a limiting piece 5, a spring 51 and a limiting block 52. Two limiting pieces 5 are symmetrically and rotatably connected to the upper parts of the mutually remote sides of the two heating frames 4. The limiting piece 5 is in an inverted L shape. The upper part of the limiting piece 5 is a clamping part. The distance between the clamping part of the limiting piece 5 and the heating frame 4 is not less than the outer diameter of the air pipe 2. The two limiting pieces 5 on the same side are symmetrically arranged left and right. A spring 51 is fixedly connected between the mutually close sides of the two limiting pieces 5 on the same side. The upper parts of the mutually remote sides of the two heating frames 4 are symmetrically and fixedly connected with limiting blocks 52 left and right. The two limiting blocks 52 on the same side are respectively located on the mutually close sides of the two limiting pieces 5. The mutually remote sides of the limiting blocks 52 are in contact with the lower parts of the limiting pieces 5. The clamping part of the limiting piece 5 is in contact with the air pipe 2.

[0027] As Figure 3 and Figure 4 shown, it further includes a protection frame 6 and a guide rod 61. The lower parts of the mutually remote sides of the two heating frames 4 are symmetrically and fixedly connected with guide rods 61 left and right. A protection frame 6 is slidably connected between the two guide rods 61 on the same side. The inner wall of the protection frame 6 is fitted with the heating frame 4. The air pipe 2 is in contact with the inner wall of the protection frame 6.

[0028] Before use, pull the protection frame 6 to move away from the heating frame 4. Under the guiding action of the guiding rod 61, the protection frame 6 is disengaged from the heating frame 4, so that the protection frame 6 can be removed. Then, pull the two limit members 5 to rotate away from each other. The spring 51 is stretched, and the lower part of the limit member 5 is disengaged from the limit block 52. Then, fit the air pipe 2 to the bottom of the heating frame 4, and respectively snap the left and right sides of the air pipe 2 between the engaging parts of the two limit members 5 and the left and right sides of the heating frame 4. Then, release the two limit members 5. Under the elastic force of the spring 51, drive the two limit members 5 to rotate towards each other, so that the engaging parts of the limit members 5 drive the left and right sides of the air pipe 2 to be wound around the outside of the heating frame 4 until the lower part of the limit member 5 contacts the limit block 52, thereby limiting the limit member 5. In this way, the air pipe 2 can be quickly and tightly fitted to the outside of the heating frame 4, and the limiting of the air pipe 2 is completed. Then, place the protection frame 6 back on the heating frame 4. Under the guiding action of the guiding rod 61, the inside of the protection frame 6 is fitted with the heating frame 4, thereby completing the installation of the air pipe 2. Similarly, the air pipe 2 can be installed on the other side.

[0029] When in need of use, insert the lower limbs into the inflatable inner bladder 72, and then control the air pump 1 to work. The compressed air is delivered to the inflatable inner bladder 72 through the air pipe 2, so that the inflatable inner bladder 72 expands and applies pressure to the lower limbs. The pressure forces the venous blood flow in the lower limbs to accelerate, thereby promoting blood to return to the heart. Then, keep the inflatable inner bladder 72 in an inflated state for a period of time to maintain the pressure, so as to further promote blood circulation. Then, the air pump 1 releases the air in the inflatable inner bladder 72, so that the inflatable inner bladder 72 shrinks and releases the pressure on the lower limbs, thereby allowing the blood to freely flow back to the lower limbs without external pressure. In this way, through intermittent pressurization of the lower limbs, the blood circulation of the lower limbs can be promoted. During this cycle, control the heating wire 41 to work, and heat the compressed air in the air pipe 2 through the heating frame 4, so that the compressed air delivered to the inflatable inner bladder 72 has a certain temperature, thereby being able to warm the extremities of the patient, keep the extremities within a suitable temperature range, and relax the vascular smooth muscle, thereby promoting vasodilation, helping to increase blood flow, and further promoting blood flow and improvement of microcirculation. In this way, the extremities can be heated according to the usage requirements, the microcirculation improvement effect is good, the recovery efficiency is improved, and the use is convenient; and by covering the air pipe 2 and the heating frame 4 with the protection frame 6, heat dissipation can be reduced, the heating effect of the compressed air in the air pipe 2 can be ensured, and at the same time, accidental touch and scalding can be prevented, and the safety of use is improved.

[0030] After use, control the air pump 1 and the heating wire 41 to stop working, so as to stop the intermittent pressurization and heating and warming of the lower limbs. Then take out the lower limbs from the inflatable inner bladder 72. Then, according to the needs, control the protection frame 6 and the limiting member 5 to move, and remove the air pipe 2 from the heating frame 4, which is convenient for storing the device when not in use. When it needs to be used later, repeat the above operations to use it normally.

[0031] As Figure 2 , Figure 3 and Figure 8 shown, it also includes a sponge pad 71. Each inflatable inner bladder 72 is attached to the inside of the sponge pad 71, and the air pipe 2 penetrates through the right side of the top of the sponge pad 71. The setting of the sponge pad 71 can protect the inflatable inner bladder 72 while effectively reducing heat loss, thereby ensuring the heating effect on the limb ends and improving work efficiency.

[0032] As Figure 2 and Figure 5 shown, it also includes a support frame 7. A support frame 7 is sleeved outside each sponge pad 71, and the air pipe 2 penetrates through the right side of the top of the support frame 7. Through the support frame 7, the inflatable inner bladder 72 and the sponge pad 71 can maintain a certain shape, improving the comfort of use.

[0033] As Figure 2 shown, it also includes an elastic sleeve 10. Elastic sleeves 10 are fixedly connected to the top openings of the sponge pads 71, and the inner sides of the elastic sleeves 10 are in contact with the lower limbs. Sealing the openings of the sponge pads 71 through the elastic sleeves 10 can effectively reduce heat loss while ensuring the fit between the inflatable inner bladder 72 and the lower limbs, thereby ensuring the effect and preventing falling.

[0034] As Figure 1 , Figure 2 , Figure 6 and Figure 8 shown, it also includes an umbrella-shaped seal 81, glove airbags 82 and connecting pipes 83. Two umbrella-shaped seals 81 are symmetrically fixedly connected to the lower parts of the two support frames 7 on the sides far away from each other. The umbrella-shaped seal 81 is made of rubber. The umbrella-shaped seal 81 is a flexible blade or flanging structure with a pointed opening that is sealed when not stressed and evenly distributed around the opening. The sides of the umbrella-shaped seals 81 close to each other are pointed and both penetrate through the sponge pad 71 to communicate with the inflatable inner bladder 72. Two glove airbags 82 are symmetrically arranged front and back and are respectively located on the sides of the two inflatable inner bladders 72 far away from each other. The tops of the two glove airbags 82 are respectively communicated with one ends of the two connecting pipes 83, and the other ends of the connecting pipes 83 are respectively in contact with the corresponding umbrella-shaped seals 81.

[0035] As Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it further includes a bolt buckle 8. Bolts buckles 8 are fixedly connected to the lower parts of the mutually remote sides of the two support frames 7. The bolt buckle 8 consists of an upper buckle, a lower buckle and a bolt. The left side of the upper buckle is rotatably connected to the left side of the lower buckle, and the right side of the upper buckle and the right side of the lower buckle are threadedly connected by the bolt. The two bolt buckles 8 are symmetrically arranged front and back. The upper buckle and the lower buckle cooperate to be able to clamp the connecting pipe 83. The bolt buckle 8 is located on the mutually remote side of the umbrella-shaped seal 81.

[0036] When it is necessary to improve the microcirculation of the patient's upper limb, by controlling the bolt of the bolt buckle 8 to be disengaged from the upper buckle and the lower buckle, the limit on the upper buckle and the lower buckle is released, and then the upper buckle is rotated to make the upper buckle and the lower buckle disengaged from each other. Then the connecting pipe 83 is inserted into the corresponding sponge pad 71. Through the contact action between the connecting pipe 83 and the tip of the umbrella-shaped seal 81, while the connecting pipe 83 can be communicated with the inflatable inner bladder 72, the tightness between the connecting pipe 83 and the inflatable inner bladder 72 can be ensured, so that the inflatable inner bladder 72 and the glove airbag 82 can be communicated. Subsequently, the upper buckle is rotated in the reverse direction to make the upper buckle and the lower buckle contact each other and clamp the connecting pipe 83. Then, by controlling the bolt of the bolt buckle 8 to be in threaded contact with the upper buckle and the lower buckle, the upper buckle and the lower buckle are re-limited, and the connecting pipe 83 can be fixed, ensuring the connection effect between the connecting pipe 83 and the inflatable inner bladder 72 and improving the safety of use. Then, the air pump 1 and the heating wire 41 are controlled to work, so that while the inflatable inner bladder 72 expands and contracts periodically, the glove airbag 82 also expands and contracts synchronously through the connecting pipe 83, so that the upper limb of the patient can be intermittently pressurized and heated and warmed at the same time, which can promote the blood circulation of the upper limb and the lower limb synchronously and improve the practicability.

[0037] As Figure 2 、 Figure 5 、 Figure 7 and Figure 8 As shown, it further includes a knob 9, a massage device 91 and a guide ring 92. Knobs 9 are symmetrically and rotatably connected to the upper parts of the front and back sides of the support frame 7. A massage device 91 is threadedly connected to the mutually close sides of the two knobs 9. Guide rings 92 are symmetrically and fixedly connected to the upper parts of the front and back sides of the sponge pad 71. The massage device 91 is slidably connected to the inside of the guide ring 92. The mutually close sides of the two massage devices 91 are respectively in contact with the front and back sides of the inflatable inner bladder 72; by rotating the knob 9, the massage device 91 can be slid along the guide ring 92 to the side close to the inflatable inner bladder 72, so as to adjust the distance between the massage device 91 and the ankle, which can meet different massage needs. Subsequently, the massage device 91 is controlled to work, and the ankle can be massaged, improving the practicability.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
