Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an emergency nursing device for open pneumothorax. Background Art

[0002] Under normal circumstances, the pressure in the pleural cavity is lower than atmospheric pressure and is a negative pressure. When the chest is damaged by penetrating trauma, the pleural cavity is connected to the outside world. If the rupture is large or there is adhesion or traction between the two layers of pleura, the rupture remains open. Air can pass through the rupture and freely enter and exit the pleural cavity with breathing, causing the patient to have difficulty breathing, a weak pulse, or even shock. This is an open pneumothorax. When a patient has an open pneumothorax, emergency rescue is required. For example, a first aid nursing device for open pneumothorax is proposed in patent announcement No. CN213642465U.

[0003] When using existing emergency care devices, it is necessary to seal the patient's wound to prevent further entry and exit of gas. However, in actual operation scenarios, such as complex emergency scene environment, frequent changes in patient position, and insufficient operational proficiency of medical staff, the device may not be able to fit tightly against the skin around the wound, resulting in air leakage, which affects the effective treatment of pneumothorax and prevents the pressure in the chest cavity from being maintained in an ideal stable state. In addition, when the patient is sent to the hospital for treatment, puncture and drainage are required for the pneumothorax patient, which can extract the gas accumulated in the chest cavity, thereby reducing the pressure in the chest cavity, reducing the pressure on the lung tissue, and gradually re-expanding it, restoring a certain gas exchange function. However, when the medical staff performs the puncture, the patient's position changes suddenly, the puncture needle is easily inserted too deep into the chest cavity, and the tip of the puncture needle is easy to puncture other organs or blood vessels, increasing the risk of the puncture operation.

[0004] Therefore, an open pneumothorax emergency nursing device is proposed to solve the above problems. Summary of the invention

After the interior of the sealing disk 3 is lowered to the set negative pressure state, the sealing disk 3 can always be maintained in the negative pressure state, and does not require a large number of fixing parts for fixing, and can be operated with one hand, thereby improving the convenience of use for medical staff.

[0037] The prompt assembly 25 includes a prompt tube 251 and a piston seat 252. The side wall of the sealing tube 121 is connected to a pneumatic tube 26. The end of the pneumatic tube 26 away from the prompt tube 251 is fixedly connected to the prompt tube 251. The piston seat 252 is slidably arranged in the prompt tube 251 and is connected to the prompt tube 251 through a spring. A pneumatic hole is provided on the side wall of the prompt tube 251 away from the pneumatic tube 26. The prompt tube 251 is a transparent structure. The upper side wall of the prompt tube 251 is fixedly connected to a prompt plate 27, which can assist the operator in judging the adsorption force between the sealing disk 3 and the patient's skin.

[0038] A pull ring 40 is fixedly connected to the upper side wall of the pull plate 20 , and a pressing handle 41 is fixedly connected to the upper side wall of the sealing cylinder 121 , so that the medical staff can pull the pull plate 20 with one hand conveniently.

[0039] The inner wall of the guide tube 9 is fixedly connected with a plurality of rubber rings 42 , and the syringe 281 passes through the plurality of rubber rings 42 , which can improve the sliding stability of the syringe 281 .

[0040] A scale 43 and an indicator light 44 are provided on the surface of the syringe 281 . The trigger switch 36 and the indicator light 44 are electrically connected to remind medical personnel of the insertion depth of the syringe 281 .

[0041] The operating principle of the present invention is now described as follows: a sterile dressing (such as vaseline gauze, sterile gauze, etc.) or a clean cloth is covered on the surface of the chest wall wound and the wound is sealed as tightly as possible. Then the operator tears off the dustproof paper 18 and covers the sealing disk 3 on the top of the cloth. The sealing disk 3 is made of silicone and can fit the human skin. The lower surface of the sealing disk 3 has adhesive (the adhesive is medical adhesive, harmless and easy to clean), which can fit the surface of the human skin. Then the operator presses the pressing handle 41 with the base of one hand, passes the finger through the pull ring 40, and Pull the pull ring 40, the pull ring 40 will drive the pull plate 20 to move, and the pull plate 20 drives the piston block 122 to move upward through the pull rod 19, so that the air pressure in the space below the piston block 122 is reduced, so that the space below the piston block 122 is in a negative pressure state, and the suction chamber 16 is connected with the sealing cylinder 121 through the insertion tube 14 and the insertion tube 13, and the air pressure inside the suction chamber 16 and the annular suction groove 17 will also decrease together, so that the sealing disk 3 and the patient's skin can be tightly adsorbed together, and the prompt cylinder 251 is connected with the sealing cylinder 121 through the air pressure tube 26. When the piston block 122 is in the sealing cylinder 121, the suction chamber 16 is connected with the sealing cylinder 121 through the air pressure tube 26. When the air pressure in the space below 22 decreases, the air pressure in the prompt cylinder 251 will also decrease, and the external gas will enter the prompt cylinder 251 through the air pressure hole on the right side of the prompt cylinder 251, so that the piston seat 252 in the prompt cylinder 251 moves to the left under the action of the air pressure. The prompt cylinder 251 is a transparent structure. When the operator finds that the piston seat 252 moves to the prompt plate 27 during the operation, the pull ring 40 can be released. As the pull ring 40 drives the pull plate 20 and the pull rod 19 to move upward, the pull rod 19 and the movable member 20 can be moved upward by the cooperation of the toothed ring 24 and the latching tooth 23. The position of the plug 122 is fixed, thereby ensuring the negative pressure state inside the sealing cylinder 121 and increasing the firmness of the contact between the adsorption sealing disk 3 and the patient's skin (the adsorption sealing disk 3 can be removed by manually lifting one side of the adsorption sealing disk 3 at a later stage). After fixing the patient's skin and the sealing disk 3, the operator wraps the first strap 1 and the second strap 2 around the patient's body and fixes the position of the sealing cylinder 121 with Velcro. When the patient's body position changes, the sealing disk 3 will also be firmly adsorbed on the skin, so that the air pressure in the patient's chest cavity is always kept in a stable state.

[0042] Then the operator needs to exhaust and decompress the patient's chest cavity. The operator adjusts the position of the guide tube 9 according to the position where the puncture needle needs to be punctured. After adjusting the position of the guide tube 9, the adjustment plate 8 and the guide tube 9 are fixed by rotating the bolts on the surface of the positioning frame 7. Then the operator holds the syringe 281 by hand to pass through the guide tube 9, and inserts the puncture end 34 at the end of the syringe 281 into the patient's skin (the puncture position is the second intercostal space of the mid-clavicular line on the injured side). When the puncture end 34 just contacts the patient's skin, the squeezing force between the puncture end 34 and the skin will squeeze the puncture end 34, and the puncture end 34 and the storage tube The space between the puncture end 34 and the induction seat 282 is filled with gas, and the puncture end 34 will drive the storage tube 31 to move by compressing the internal air pressure, and the storage tube 31 will drive the connecting frame 30 to slide in the induction seat 282 until the connecting frame 30 is squeezed to the inner wall of the induction seat 282, and the induction seat 282 will apply a hard thrust to the storage tube 31 and the puncture end 34, so that the puncture end 34 passes through the patient's skin. When the operator finds that the puncture end 34 has passed through the patient's skin, he needs to press the control button 39 by hand, and the control button 39 will transmit the external current to the moving contact inside the trigger switch 36. When the puncture end 34 and the storage tube 31 pass through the skin and reach the patient, After the chest cavity is opened, the storage tube 31 will not be blocked by the muscles. Under the elastic force of the spring, the sensing seat 282 will drive the connecting frame 30 to move a certain distance. The connecting frame 30 will squeeze the moving contact of the trigger switch 36, so that the moving contact and the static contact of the trigger switch 36 will contact, thereby opening the control valve 38, so that the compressed gas inside the storage tube 31 is discharged through the exhaust hole 37. The piston column 33 will drive the puncture end 34 to retract into the storage tube 31 under the tension of the spring, and the silicone sleeve 35 will be at the front end of the storage tube 31. Even if the patient's body position changes during the puncture process, the soft silicone sleeve 35 will not It will not cause damage to other organs in the body, thereby reducing the risk of the puncture operation. The trigger switch 36 will also control the indicator light 44 to light up, reminding the operator that the storage tube 31 is already in the chest cavity. The operator only needs to continue pushing forward a certain distance (for example, the distance between the storage tube 31 and the vent 29 is 1 cm, and the operator only needs to continue pushing 1 cm according to the scale 43 to make the vent 29 in the chest cavity). Then the operator controls the drainage mechanism 10 to work, and the drainage mechanism 10 discharges the gas inside the chest cavity through the drainage tube 11, the syringe 281 and the vent 29, so as to achieve the purpose of exhaust and decompression.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
