Description

Technical Field

[0001] The present invention relates to the field of emergency treatment devices, and particularly to a multi-purpose first aid device for emergency hemostasis, drainage and abdominal cavity expansion of the abdominal cavity. Background Art

[0002] In the field of emergency treatment, massive bleeding is the primary factor leading to death before patients arrive at the hospital. Since the trunk houses most of the human organs, the abdominal aorta and vena cava play a crucial role in the human blood circulation, connecting the upper and lower parts. Therefore, trauma to the trunk organs or large blood vessels, represented by the liver, spleen, kidney, abdominal aorta and vena cava, due to their large bleeding volume and fast bleeding speed, has become the top priority in pre-hospital first aid.

[0003] The abdominal cavity is a closed cavity in the human body, and the internal pressure therein is called the intra-abdominal pressure, which changes with the changes in the internal volume of the abdominal cavity and abdominal compliance. Therefore, when the internal volume of the abdominal cavity is larger or the abdominal compliance is smaller, the intra-abdominal pressure will increase, and vice versa. When massive bleeding occurs in the abdominal cavity, the large amount of blood pouring in within a short time can lead to a rapid increase in the internal volume of the abdominal cavity, and then cause an increase in the intra-abdominal pressure. The increase in intra-abdominal pressure can trigger a series of serious complications. Therefore, when massive abdominal bleeding occurs, on the one hand, emergency hemostasis measures are needed to reduce the risk of the patient dying from hemorrhagic shock; on the other hand, it is necessary to start from reducing the internal volume of the abdominal cavity, drain the accumulated blood in the abdominal cavity to avoid its adverse effects on the intra-abdominal pressure and the body; furthermore, the internal space of the abdominal cavity can be expanded by relaxing the abdominal muscles and increasing the abdominal compliance, so as to improve the body's adaptability and tolerance to the increase in the internal volume of the abdominal cavity.

[0004] However, currently there is still a lack of an integrated device in clinical practice that can simultaneously achieve abdominal hemostasis, abdominal drainage, and abdominal cavity volume expansion. Existing devices can only achieve a single medical purpose and all have a series of defects, which is not conducive to the development of emergency hemostasis rescue, nor to the embodiment of the concept of caring for the wounded and the spirit of humanitarian rescue. Therefore, there is an urgent need for an integrated multi-purpose first aid device that can simultaneously achieve abdominal hemostasis, abdominal drainage, abdominal cavity volume expansion and intra-abdominal pressure monitoring to improve the clinical situation. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention provides a multi-purpose first aid device for emergency hemostasis, drainage and abdominal cavity expansion of the abdominal cavity, which can integrally achieve abdominal hemostasis, abdominal drainage and abdominal cavity volume expansion to improve the clinical situation.

[0006] The object of the present invention is achieved through the following technical solutions:

[0007] A multi-purpose first aid device for emergency hemostasis, drainage and abdominal cavity expansion of the abdominal cavity provided by the present invention includes:

[0008] A penetrating part, the bottom of which can penetrate into the interior of the abdominal cavity through an incision in the patient's abdominal wall, and the top of which is located outside the abdominal cavity and is provided with a lifting part;

[0009] A hemostasis and drainage mechanism, which is slidably penetrated in the penetrating part and is used for pressing and stopping bleeding at the bleeding position in the abdominal cavity and for abdominal drainage; and

[0010] An expansion mechanism, which includes a lifting plate and a driving component. The lifting plate is rotatably installed on one side of the bottom of the penetrating part, and the driving component is used to drive the lifting plate to rotate so that the lifting plate can turn outwards or inwards.

[0011] Further, the hemostasis and drainage mechanism includes a penetrating column, an airbag, an air injection pipe and a drainage pipe. The penetrating column is slidably penetrated in the penetrating part. The bottom end of the penetrating column is used to penetrate into the interior of the abdominal cavity and is provided with an airbag. Both the air injection pipe and the drainage pipe are installed inside the penetrating column. One end of the air injection pipe is externally connected to an inflation device and the other end is communicated with the airbag. One end of the drainage pipe is externally connected to a drainage device and the other end can be communicated with the abdominal cavity.

[0012] Further, the end of the drainage pipe communicated with the abdominal cavity is provided with a plurality of branch pipes, and each branch pipe faces in all directions inside the abdominal cavity.

[0013] Further, each branch pipe is located inside the airbag and the end part of each branch pipe penetrates out of the airbag from all directions.

[0014] Further, it further includes a pressure measuring mechanism, which includes a pressure measuring device and a data line. The data line is installed inside the penetrating column. One end of the data line penetrates out from one side of the bottom end of the penetrating column and is electrically connected to the pressure measuring device, and the other end of the data line is externally connected to a monitor.

[0015] Further, the driving component includes a driving channel, a shunt pipe, a first elastic member, a rack and a transmission gear. The driving channel is arranged inside the penetrating part and penetrates through the top and bottom of the penetrating part. One end of the shunt pipe is communicated with the air injection pipe and the other end is communicated with the top opening of the driving channel. The transmission gears are circumferentially distributed around the rotation axis of the lifting plate at the rotation connection end of the lifting plate. The rack is slidably installed inside the driving channel, and the bottom end penetrates out of the bottom opening of the driving channel and is in transmission connection with the transmission gear. The first elastic member connects the rack and the driving channel to provide an elastic force to move the rack away from the abdominal cavity.

[0016] Further, a travel groove is provided in the middle of the driving channel, a travel block is provided at the top of the rack, the travel block is slidably located in the travel groove, a receiving groove is provided at the top of the travel groove, and the first elastic member is installed in the receiving groove and connected to the travel block to provide an elastic force for abutting the travel block against the top of the travel groove. When the travel block abuts against the top of the travel groove, the plate surface of the rack-driven lifting plate is parallel to the penetration direction of the penetration part. When the travel block abuts against the bottom of the travel groove, the plate surface of the rack-driven lifting plate is perpendicular to the penetration direction of the penetration part.

[0017] Further, a plurality of the expansion mechanisms are circumferentially and uniformly arranged around the penetration part.

[0018] Further, a plurality of injection needles are uniformly distributed on one side of the lifting plate close to the abdominal wall. A first injection channel is provided in the lifting plate, the first injection channel is communicated with each injection needle, a second injection channel extending downward is opened at the top of the penetration part, and the second injection channel is communicated with the first injection channel.

[0019] Further, a feed groove is provided corresponding to each injection needle on the side of the first injection channel close to the injection needle. A push block is slidably arranged in the feed groove. The bottom end of the injection needle is connected to the push block and the top end can slidably penetrate through the lifting plate. A through hole communicating the first injection channel with the injection needle is opened on the push block. The push block and the feed groove are connected by a second elastic member, and the second elastic member can provide an elastic force for moving the injection needle into the feed groove.

[0020] As can be seen from the above technical solutions, a multi-purpose first-aid device for emergency hemostasis, drainage, and abdominal cavity expansion provided by the present invention uses the penetration part to provide an operation channel for the hemostasis and drainage mechanism, the expansion mechanism, and the pressure measurement mechanism, and can directly press and stop bleeding at the bleeding site. The insertion column and the airbag are not only means for pressing and stopping bleeding, but also carriers for abdominal cavity drainage, and can use the same abdominal wall incision to simultaneously press the bleeding site and drain the abdominal cavity; the expansion mechanism in the present invention uses the air pressure generated when injecting gas into the airbag, so that the rack drives the lifting plate to rotate and unfold under the action of the air pressure. While the airbag expands to press the bleeding site, the abdominal wall of the patient can be quickly lifted and expanded, and the operation of reducing abdominal pressure can be quickly performed, realizing the simultaneous activation of airbag pressing and abdominal wall lifting, saving too many operation steps, and winning precious time for saving the patient's life; by using the contact between the lifting plate and the abdominal wall when lifting the abdominal wall, the injection needle is set on the lifting plate, and at the same time, by using the method of secondary penetration, botulinum toxin can be directly injected and act on the patient's abdominal wall, effectively improving the relaxation effect of the abdominal wall. The present invention coordinates the operations of hemostasis, drainage, and abdominal cavity expansion in the abdominal cavity, so that the operations of abdominal cavity hemostasis, drainage, and abdominal cavity expansion can complement each other and interact with each other, greatly shortening the operation interval between multiple operations and winning precious time for the treatment of patients.

[0030] To make the above objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] As Figures 1-3 shown, a multi-purpose first aid device for emergency hemostasis, drainage, and abdominal cavity expansion in the abdominal cavity provided in this embodiment includes a penetrating part 1, a hemostasis and drainage mechanism 2, and an expansion mechanism 3.

[0034] Please refer to Figure 1 , the bottom of the penetrating part 1 can penetrate into the abdominal cavity through the abdominal wall incision of the patient, and its top is located outside the abdominal cavity and is provided with a lifting part 11. During specific use, holding the lifting part 11 can extend or pull out the penetrating part 1 into the abdominal cavity. Preferably, the bottom of the penetrating part 1 has a groove body that can be used to accommodate the hemostasis and drainage mechanism 2 in a folded state.

[0035] Please continue to refer to Figure 1, the hemostatic drainage mechanism 2 is slidably disposed through the insertion portion 1, and is used for pressing and stopping bleeding at the bleeding position in the abdominal cavity and performing abdominal drainage.

[0036] In one embodiment, the hemostatic drainage mechanism 2 includes an insertion column 21, an airbag 22, an air injection tube 23, and a drainage tube 24. The insertion column 21 is slidably disposed through the insertion portion 1 along the insertion direction of the insertion portion 1. Among them, the insertion column 21 is made of a hard material such as hard plastic or metal, and is not easily deformed, ensuring that the internal pipelines will not be squeezed and deformed or blocked. In specific use, the top end of the insertion column 21 passes through the insertion portion 1 and is exposed outside the abdominal cavity, and the bottom end of the insertion column 21 is used to penetrate into the abdominal cavity and is provided with an airbag 22. The airbag 22 is in a folded state without inflation in the initial state. Both the air injection tube 23 and the drainage tube 24 are flexible tubes, and both the air injection tube 23 and the drainage tube 24 are installed inside the insertion column 21 to ensure that they will not be squeezed and deformed or blocked. One end of the air injection tube 23 is externally connected to an inflation device and the other end is communicated with the airbag 22. The inflation device injects air into the airbag 22 through the air injection tube 23, so that the airbag 22 is filled and inflated, thereby playing a role in pressing and stopping bleeding of the bleeding organ or blood vessel. Among them, the externally connected inflation device selects an existing product on the market, so no further description is needed. One end of the drainage tube 24 is externally connected to a drainage device and the other end can be communicated with the abdominal cavity. The drainage device can select a negative pressure aspirator or an anti-reflux drainage bag.

[0037] Preferably, one end of the drainage tube 24 communicated with the abdominal cavity is provided with a plurality of branch tubes 241, and each branch tube 241 faces in each direction in the abdominal cavity. The drainage tube 24 communicates with a plurality of branch tubes 241 facing in each direction, which can ensure that when a certain drainage port is blocked by accumulated blood, the remaining drainage ports can still play a role in sucking out the accumulated blood in the abdominal cavity.

[0038] Furthermore, in one embodiment, each branch tube 241 is located inside the airbag 22 and the end portions thereof pass through the airbag 22 in each direction. In specific use, after the airbag 22 is inflated and expanded, the volume becomes larger, which can increase the distance between the branch tubes 241, so that the branch tubes 241 can drain in a larger range and improve the drainage efficiency. It should be noted that the drainage tube 24 plays a role in draining the accumulated blood in the abdominal cavity, so the lumen of the drainage tube 24 is not communicated with the airbag 22 to ensure that the airbag can be fully inflated.

[0039] Clinically, the change of intra-abdominal pressure is indirectly reflected by measuring the pressure in the bladder. This method can only be used for patients with a urinary catheter. If the patient has a situation where a urinary catheter cannot be placed, such as a ruptured bladder or a urethral rupture, the pressure in the bladder cannot be measured. Therefore, in order to measure the abdominal pressure of the patient more accurately, in one embodiment, a pressure measuring mechanism 4 is further included. The pressure measuring mechanism 4 includes a pressure gauge 41 and a data line 42. The data line 42 is installed inside the insertion column 21. One end of the data line 42 passes out from one side of the bottom end of the insertion column 21 and is electrically connected to the pressure gauge 41. The other end of the data line 42 is externally connected to a monitor for continuously monitoring the intra-abdominal pressure of the patient. When the airbag 22 is in the folded state without inflation, the pressure measuring mechanism 4 can be placed in the folding sandwich layer. After the airbag is inflated and expanded, the originally folded pressure measuring mechanism 4 will pop outwards to measure the abdominal pressure.

[0040] Please refer to Figures 1-3 , the expansion mechanism 3 includes a lifting plate 31 and a driving component 32. The lifting plate 31 is rotatably installed on one side of the bottom of the penetration part 1. The driving component 32 is used to drive the lifting plate 31 to rotate so that the lifting plate 31 can be turned outwards or inwards.

[0041] As Figure 2 shown, specifically, in one embodiment, the driving component 32 includes a driving channel 321, a shunt tube 322, a first elastic member 323, a rack 324 and a transmission gear 325. The driving channel 321 is arranged inside the penetration part 1 and penetrates through the top and bottom of the penetration part 1. One end of the shunt tube 322 is communicated with the air injection tube 23 and the other end is communicated with the top opening of the driving channel 321 for carrying the air inlet channel. The transmission gears 325 are circumferentially distributed around the rotation connection end of the lifting plate 31 with the rotation axis of the lifting plate 31 as the center line. The rack 324 is slidably installed inside the driving channel 321, and the bottom end passes out from the bottom opening of the driving channel 321 and is in transmission connection with the transmission gear 325. The first elastic member 323 connects the rack 324 with the driving channel 321 to provide an elastic force to move the rack 324 away from the abdominal cavity. Among them, the first elastic member 323 can be a spring. During specific use, the air injection tube 23 is inflated through an external inflation device. The gas is shunted into the driving channel 321 along the shunt tube 322. Under the action of the gas pressure, the rack 324 is driven to slide towards the bottom of the penetration part 1, thereby driving the lifting plate 31 to turn outwards. At this time, by pulling the pulling part 11 outwards, the lifting plate 31 can be used to lift the abdominal wall, and finally the purpose of expanding the volume of the abdominal cavity content can be achieved. When the inflation device stops inflating, the rack 324 will move upwards under the elastic force of the first elastic member 323 and drive the lifting plate 31 to turn inwards. When the pulling part 11 is moved a large distance, the insertion column 21 can be slid downwards as appropriate and the bleeding part can be pressed to avoid the possibility of failure of hemostasis due to insufficient downward pressure of the airbag 22.

[0042] To prevent the excessive or insufficient movement of the rack 324 under the action of air pressure, which may lead to excessive or insufficient deployment of the lifting plate 31 and affect the lifting effect of the lifting plate 31 on the abdominal wall. Therefore, in one embodiment, the stroke of the rack 324 is restricted. A stroke groove 3211 with a size larger than that of the driving channel 321 is further provided in the middle of the driving channel 321. A stroke block 3241 is provided at the top of the rack 324. The stroke block 3241 is slidably located in the stroke groove 3211 and is in close contact with the side wall of the stroke groove 3211. A receiving groove 3212 with a size slightly smaller than that of the stroke groove 3211 is provided at the top of the stroke groove 3211. The first elastic member 323 is installed in the receiving groove 3212 and is connected to the stroke block 3241 to provide an elastic force for abutting the stroke block 3241 against the top of the stroke groove 3211. When the stroke block 3241 abuts against the top of the stroke groove 3211, the plate surface of the lifting plate 31 driven by the rack 324 is parallel to the penetration direction of the penetration portion 1. When the stroke block 3241 abuts against the bottom of the stroke groove 3211, the plate surface of the lifting plate 31 driven by the rack 324 is perpendicular to the penetration direction of the penetration portion 1. When the bottom end of the penetration portion 1 enters the abdominal cavity, no gas is injected into the injection tube 23. At this time, both the airbag 22 and the pressure measuring mechanism 4 are in a folded state, and the plate surface of the lifting plate 31 is also parallel to the penetration direction of the penetration portion 1, facilitating the entry of the device; when performing compression hemostasis and it is necessary to expand the abdominal cavity volume, the inflation device injects gas into the injection tube 23. While the airbag 22 expands, the lifting plate 31 will also expand to be perpendicular to the penetration direction of the penetration portion 1. At this time, the contact area between the lifting plate 31 and the abdominal wall is the largest, which is most conducive to lifting the abdominal wall.

[0043] Preferably, a plurality of expansion mechanisms 3 are circumferentially and uniformly arranged around the penetration portion 1 to lift the abdominal wall over a larger range.

[0044] When the effect of the lifting plate 31 in expanding the abdominal cavity space is not very ideal, the abdominal wall can be relaxed by injecting botulinum toxin into the abdominal muscles to further expand the internal space of the abdominal cavity. Therefore, as Figure 3 shown, preferably, a plurality of injection needles 311 are uniformly arranged on the side of the lifting plate 31 close to the abdominal wall. A first injection channel 312 is provided in the lifting plate 31. The first injection channel 312 is communicated with each injection needle 311. A second injection channel 12 extending downward is opened at the top of the penetration portion 1. The second injection channel 12 is communicated with the first injection channel 312. Specifically, the connection between the second injection channel 12 and the first injection channel 312 can be an external pipeline or a connection at the rotating joint.

[0045] Due to the large number of injection needles 311, there may be a situation where some needles do not penetrate the abdominal wall thoroughly, thus affecting the effect of abdominal wall relaxation. In one embodiment, a feeding groove 3121 is provided on the side of the first injection channel 312 close to each injection needle 311. A pushing block 3122 is slidably arranged in the feeding groove 3121. The edge of the pushing block 3122 is in close fit with the side wall of the feeding groove 3121. The bottom end of the injection needle 311 is connected to the pushing block 3122 and the top end thereof slidably passes through the lifting plate 31. A through hole communicating the first injection channel 312 with the injection needle 311 is formed in the pushing block 3122. The pushing block 3122 and the feeding groove 3121 are connected by a second elastic member 3123. The second elastic member 3123 can provide an elastic force for moving the injection needle 311 into the feeding groove 3121. Among them, the second elastic member 3123 can be a spring. In specific use, by lifting the lifting plate 31 upward, each injection needle 311 can be initially inserted into the patient's abdominal wall. Then, botulinum toxin is injected into the orifice of the second injection channel 12. Under the push of hydraulic pressure, the pushing block 3122 can further push the injection needle 311 to be inserted into the abdominal wall for the second time, ensuring that each injection needle 311 can be effectively injected, so as to more effectively achieve the purpose of expanding the abdominal cavity volume and reducing the intra-abdominal pressure.

[0046] When the multi-purpose first aid device for abdominal emergency hemostasis, drainage and abdominal cavity expansion provided by the present invention is in specific use, in the initial state, the airbag 22 and the pressure measuring mechanism 4 are kept in a folded state and located in the groove at the bottom of the penetrating part 1, and the lifting plate 31 is in a state parallel to the penetrating direction of the penetrating part 1; after the bottom of the penetrating part 1 enters the abdominal cavity through the abdominal wall incision of the patient, an external inflation device is started, and gas enters the airbag 22 through the injection tube 23 to make it expand and unfold. The extending column 21 is slid downward to press and stop bleeding at the bleeding part. At the same time, the pressure measuring mechanism 4 unfolds and performs real-time pressure measurement. And the gas will also enter the driving channel 321 through the shunt tube 322. Under the action of the gas pressure, the rack 324 slides downward and drives the lifting plate 31 to rotate and unfold outward; an external drainage device is started to drain the accumulated fluid in the abdominal cavity out of the patient's body through multiple branch tubes 241; when it is necessary to expand the abdominal cavity volume of the patient, the pulling part 11 is pulled outward and the airbag 22 is kept pressing on the bleeding part, and the lifting plate 31 lifts the abdominal wall to expand the abdominal cavity volume, thereby reducing the abdominal pressure; when it is necessary to further expand the abdominal cavity volume of the patient, botulinum toxin is injected into the orifice of the second injection channel 12. The injection needle 311 is further inserted into the patient's abdominal wall under the push of hydraulic pressure and injection is performed to achieve the purpose of expanding the abdominal cavity volume and reducing the intra-abdominal pressure.

[0047] The present invention uses the insertion part 1 to provide an operation channel for the hemostasis and drainage mechanism 2, the abdominal cavity expansion mechanism 3 and the pressure measurement mechanism 4, and can directly press and stop bleeding at the bleeding site. The insertion column 21 and the airbag 22 are not only means for pressing and stopping bleeding, but also carriers for abdominal cavity drainage, and can use the same abdominal wall incision to simultaneously press the bleeding site and perform abdominal cavity drainage; in the expansion mechanism 3 of the present invention, the air pressure generated when the airbag 22 is inflated with gas causes the rack 324 to drive the lifting plate 31 to rotate and unfold under the action of the air pressure. While the airbag 22 expands to press the bleeding site, the abdominal wall of the patient can be quickly lifted and expanded, and the operation of reducing abdominal pressure can be quickly performed, realizing the simultaneous activation of the airbag 22 pressing and the abdominal wall lifting, saving excessive operation steps and winning precious time for saving the patient's life; by using the contact between the lifting plate 31 and the abdominal wall when lifting the abdominal wall, the injection needle 311 is arranged on the lifting plate 31, and at the same time, by using the method of secondary puncture, botulinum toxin can be directly injected and act on the patient's abdominal wall, effectively improving the relaxation effect of the abdominal wall. The present invention coordinates the operations of hemostasis, drainage and abdominal cavity expansion in the abdominal cavity, so that the operations of abdominal cavity hemostasis, drainage and abdominal cavity expansion can complement each other and interact with each other, greatly shortening the operation interval between multiple operations and winning precious time for the treatment of patients.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
