Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a blocking device for emergency treatment of chest trauma. Background Art

[0002] During natural disasters, field training and some special environments, pneumothorax or hemothorax may occur when the human body is hit hard by external forces or falls from heights. Since there is no effective medical environment or medical equipment in these areas, rescue may be delayed, resulting in pleural effusion and suffocation of the patient.

[0003] The existing blocking device has the following problems when used:

[0004] 1. The installation process of the existing blocking device consumes a lot of time, which is not suitable for emergency use scenarios where every second counts, and it is easy to miss the emergency time.

[0005] 2. After chest trauma in outdoor environments, the pleural effusion is easily mixed with debris, causing the effusion to become turbid and viscous. The existing blocking device cannot quickly form active external suction force on the pleural effusion, causing blockage and accumulation of the effusion, affecting the patient's recovery. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a closure device for emergency treatment of chest trauma, which aims to solve the problem that the installation process speed of existing closure devices is too low.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A closure device for emergency treatment of thoracic trauma comprises a drainage tube with its upper portion inserted into the thoracic wound, a one-way drain valve fixedly mounted on the upper end of the drainage tube and used to direct pleural effusion to flow unidirectionally toward the lower end of the drainage tube, a mounting assembly mounted on the drainage tube and used to maintain relative stillness between the upper portion of the drainage tube and the inner wall of the thoracic wound, a drain assembly mounted on the lower end of the drainage tube and used to drain pleural effusion, and a pair of tightening assemblies spaced apart in the vertical direction and mounted on the left and right sides of the middle section of the drainage tube and used to contract the skin surface of the thoracic wound.

[0009] The mounting assembly includes a blocking airbag fixedly mounted on the upper outer wall of the drainage tube, an inflatable airbag fixedly mounted on the lower outer wall of the drainage tube, a pair of connecting tubes fixedly mounted on the front and rear sides of the outer wall of the drainage tube and used to connect the blocking airbag and the inflatable airbag, and an elastic tightening sleeve movably mounted on the outside of the blocking airbag along the length direction of the drainage tube;

[0010] The drainage assembly includes a drainage tube fixedly connected to the lower end of the drainage tube, a liquid collecting bag fixedly arranged at the lower end of the drainage tube, a negative pressure tube fixedly arranged on the liquid collecting bag and connected to the interior of the liquid collecting bag, an elastic negative pressure airbag fixedly arranged at the free end of the negative pressure tube, a one-way inflation valve arranged in the negative pressure tube and allowing the gas in the liquid collecting bag to flow in one direction into the negative pressure airbag, and a one-way exhaust valve arranged on the negative pressure airbag and used to allow the gas in the negative pressure airbag to flow in one direction to the outside.

[0011] More preferably, each tightening assembly includes an elastic tensioning strip with a middle section fixed to the outer wall of the drainage tube and two front and rear sections respectively arranged around the outer wall of the drainage tube, a fitting strip fixed between the two ends of the tensioning strip, and an adhesive sheet fixed to the lower side of the fitting strip.

[0012] More preferably, an outer expansion ring is fixedly provided at the rear end of the tightening sleeve.

[0013] More preferably, a blocking plate is fixedly provided at the front end of the drainage tube.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention extends the upper end of the drainage tube into the wound, pushes the drainage tube inward, and pulls back the tightening sleeve, causing the sealing airbag to expand and abut against the inner wall of the chest wound, thereby achieving a sealing effect. The process is fast and convenient, and is suitable for emergency rescue tasks in unexpected situations.

[0016] 2. The present invention uses the drainage component to suck the viscous accumulated liquid at the upper end of the drainage tube into the liquid collection bag through negative pressure, thereby preventing the problem of liquid accumulation;

[0017] 3. The present invention uses the tightening strips on both sides to pull and tighten the skin on both sides of the wound opening toward the drainage tube, thereby shrinking the wound and compressing the wound to achieve emergency and rapid hemostasis. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment of a closure device for emergency treatment of chest trauma includes a drainage tube 1 with an upper portion inserted into the chest wound, a one-way drainage valve 2 fixed to the upper end of the drainage tube 1 and used to allow pleural effusion to flow unidirectionally toward the lower end of the drainage tube 1, a mounting assembly 3 provided on the drainage tube 1 and used to maintain relative stillness between the upper portion of the drainage tube 1 and the inner wall of the chest wound, a drainage assembly 4 provided at the lower end of the drainage tube 1 and used to drain the pleural effusion, and a pair of tightening assemblies 5 spaced apart in the vertical direction and provided on the left and right sides of the middle section of the drainage tube 1 and used to contract the skin surface of the chest wound.

[0026] The mounting assembly 3 includes a blocking airbag 31 fixed to the upper outer wall of the drainage tube 1, an inflatable airbag 32 fixed to the lower outer wall of the drainage tube 1, a pair of connecting tubes 33 fixed to the front and rear sides of the outer wall of the drainage tube 1 and used to connect the blocking airbag 31 and the inflatable airbag 32, and an elastic tightening sleeve 34 movably sleeved on the outside of the blocking airbag 31 along the length of the drainage tube 1.

[0027] The drainage assembly 4 includes a drainage tube 41 fixedly connected to the lower end of the drainage tube 1, a liquid collecting bag 42 fixedly mounted at the lower end of the drainage tube 41, a negative pressure tube 43 fixedly mounted on the liquid collecting bag 42 and connected to the interior of the liquid collecting bag 42, an elastic negative pressure airbag 44 fixedly mounted at the free end of the negative pressure tube 43, a one-way inflation valve 45 arranged in the negative pressure tube 43 and allowing the gas in the liquid collecting bag 42 to flow in one direction into the negative pressure airbag 44, and a one-way exhaust valve 46 arranged on the negative pressure airbag 44 and used to allow the gas in the negative pressure airbag 44 to flow in one direction to the outside.

[0028] When the product is in use, the upper end of the drainage tube 1 is inserted into the patient's chest wound, and after the upper end of the tightening sleeve 34 is extended into the wound, as the drainage tube 1 continues to penetrate deeper, the rear end of the tightening sleeve 34 is gradually pulled backward, causing the blocking airbag 31 to gradually break away from the squeezed and compressed position of the tightening sleeve 34 from top to bottom, and in the process of pulling the tightening sleeve 34 down, the tightening sleeve 34 gradually breaks away from the blocking airbag 31 and is gradually sleeved on the inflatable airbag 32, thereby generating a tightening and squeezing force on the inflatable airbag 32, and the gas in the inflatable airbag 32 is input into the blocking airbag 31 along the connecting pipe 33, prompting the blocking airbag 31 to gradually expand, until the blocking airbag 31 expands to fully support the wound and fits tightly with the inner wall of the wound, and the inflatable airbag 32 can no longer be compressed. At this time, the tightening sleeve 34 is stopped from being pulled down. The wound is sealed, and the fluid accumulated in the chest wound flows into the drainage tube 1 through the one-way drainage valve 2 and into the fluid collection bag 41. When drainage is blocked, the gas inside the negative pressure airbag 44 is discharged through the one-way exhaust valve 46 by squeezing the negative pressure airbag 44, and the negative pressure airbag 44 relies on its own elastic recovery force to discharge the gas in the fluid collection belt 42 into the negative pressure airbag 44 through the one-way inflation valve 45, causing the gas content in the fluid collection bag 41 to decrease and become a negative pressure state. By quickly and repeatedly pressing the negative pressure airbag 44, the negative pressure effect can be increased, so that the fluid accumulated in the chest cavity is affected by the atmospheric pressure and is sucked into the drainage tube 1 along the one-way drainage valve 2 and collected in the fluid collection bag 41, completing the preliminary cleaning and discharge of the chest effusion, achieving the initial stabilization of the patient's physical condition and achieving the first aid effect.

[0029] like Figure 1 、 Figure 2 and Figure 4 As shown, each tightening assembly 5 includes an elastic tensioning strip 51 whose middle section is fixed to the outer wall of the drainage tube 1 and whose front and rear sections are respectively arranged around the outer wall of the drainage tube 1, a fitting strip 52 fixed between the two ends of the tensioning strip 51, and an adhesive sheet 53 fixed on the lower side of the fitting strip 52.

[0030] When using this product, the two tensioning strips 51 can be wrapped around the outer wall of the drainage tube 1 at the factory and tied and fixed with ropes to prevent them from affecting the movement of the tightening sleeve 34. When in use, each bonding strip 52 is pulled away from the drainage tube 1 to the appropriate position away from the wound opening, and the adhesive sheet 53 is attached to the corresponding part of the patient's skin, so that the tensioning strip 51 applies a pulling force toward the drainage tube 1 on the corresponding part of the skin, thereby prompting the skin on both sides of the wound to tighten and gather toward the drainage tube 1, quickly and steadily shrinking the size of the wound opening, and achieving the effect of compression and hemostasis.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, an outer expansion ring 6 is fixed to the rear end of the tightening sleeve 34 .

[0032] When the product is in use, the rear end of the tightening sleeve 34 is expanded outward by the setting of the outer expansion ring 6, so that when the operator takes off the tightening sleeve 34, the rear end of the tightening sleeve 34 can be smoothly sleeved on the inflatable airbag 32, which is convenient for the operator to use.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, a blocking plate 7 is fixedly provided at the front end of the drainage tube 1 .

[0034] When the product is in use, the blocking plate 7 is set to prevent the upper end of the blocking airbag 31 from expanding upwards and blocking the upper port of the drainage tube 1.

[0035] The working principle of this device is:

[0036] The first step: insert the upper end of the drainage tube 1 into the patient's chest wound, and after the upper end of the tightening sleeve 34 is extended into the wound, as the drainage tube 1 continues to penetrate deeper, the rear end of the tightening sleeve 34 is gradually pulled backward, causing the blocking airbag 31 to gradually break away from the squeezed and compressed position of the tightening sleeve 34 from top to bottom, and in the process of pulling the tightening sleeve 34 down, the tightening sleeve 34 gradually breaks away from the blocking airbag 31 and is gradually sleeved on the inflatable airbag 32, thereby generating a tightening and squeezing force on the inflatable airbag 32, and the gas in the inflatable airbag 32 is input into the blocking airbag 31 along the connecting tube 33, prompting the blocking airbag 31 to gradually expand, until the blocking airbag 31 expands to fully support the wound and fits tightly with the inner wall of the wound, and the inflatable airbag 32 can no longer be compressed. At this time, stop pulling down the tightening sleeve 34 to complete the sealing of the wound.

[0037] Step 2: Remove the binding ropes that bind each tightening component 5, and then pull each fitting strip 52 away from the drainage tube 1 to the appropriate position away from the wound opening, and then fit the adhesive sheet 53 on the corresponding patient's skin, so that the tensioning strip 51 applies a pulling force toward the drainage tube 1 on the corresponding skin, thereby prompting the skin on both sides of the wound to tighten and gather toward the drainage tube 1, quickly and steadily shrinking the size of the wound opening, and achieving the effect of compression and hemostasis.

[0038] Step 3: The fluid accumulated in the chest wound flows into the drainage tube 1 and into the fluid collection bag 41 through the one-way drainage valve 2. When the drainage is blocked, the gas inside the negative pressure airbag 44 is discharged through the one-way exhaust valve 46 by squeezing the negative pressure airbag 44, and the negative pressure airbag 44 relies on its own elastic recovery force to discharge the gas in the fluid collection belt 42 into the negative pressure airbag 44 through the one-way inflation valve 45, causing the gas content in the fluid collection bag 41 to decrease and become a negative pressure state. By quickly and repeatedly pressing the negative pressure airbag 44, the negative pressure effect can be increased, so that the fluid accumulated in the chest cavity is affected by the atmospheric pressure and is sucked into the drainage tube 1 along the one-way drainage valve 2 and collected in the fluid collection bag 41, completing the preliminary cleaning and discharge of the chest effusion, achieving the initial stabilization of the patient's physical condition and achieving the first aid effect.

Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
