Description

Technical Field

[0001] This utility model relates to the field of human life necessities, and in particular to medical auxiliary equipment, especially a portable drainage auxiliary negative pressure device. Background Technology

[0002] In existing technology, the negative pressure port of the chest drainage bottle is connected to a wall-mounted suction device to maintain negative pressure inside the drainage bottle, thereby draining pleural effusion through negative pressure. However, the following problems exist in its use:

[0003] 1. When the patient needs to get out of bed and move around, the negative pressure tube of the wall-mounted drainage device needs to be removed briefly, which will cause the negative pressure drainage to be suspended.

[0004] 2. When patients get out of bed and return, they may forget to insert the negative pressure tube back into the chest drainage bottle. This is often not discovered until medical staff check on them. By then, the negative pressure drainage has been stopped for a long time, which seriously affects the drainage effect. Summary of the Invention

[0005] The purpose of this utility model is to provide a portable drainage-assisted negative pressure device, which aims to solve the technical problems in the prior art where negative pressure drainage is interrupted due to the patient getting out of bed and moving, or where negative pressure drainage is stopped for a long time due to forgetting to reinsert the negative pressure tube.

[0006] A portable negative pressure drainage device is disclosed, which is used in conjunction with a chest drainage bottle and a wall-mounted suction device. The device includes a negative pressure device body, a first connecting tube, and a second connecting tube. The top of the negative pressure device body has a first insertion slot and a second insertion slot. The outer end of the first insertion slot is inserted into one end of the first connecting tube, and the other end of the first connecting tube is connected to the negative pressure port of the chest drainage bottle. The outer end of the second insertion slot is inserted into one end of the second connecting tube, and the other end of the second connecting tube is connected to the wall-mounted suction device. An air pump, a power supply, a switch, and a microswitch are installed inside the negative pressure device body. The inner end of the first insertion slot is connected to the air inlet of the air pump, and the inner end of the second insertion slot is connected to the air outlet of the air pump. The trigger end of the microswitch is located on the inner wall of the second insertion slot. The positive terminal of the power supply, the switch, the air pump, the microswitch, and the negative terminal of the power supply are connected in series.

[0007] Furthermore, the switch is a sliding rheostat switch.

[0008] Furthermore, an indicator light is installed on the outer surface of the negative pressure device body, and the positive terminal of the power supply, the indicator light, the switch, the air pump, the micro switch, and the negative terminal of the power supply are connected in series.

[0009] Furthermore, a thumb clamp is installed on one side of the negative pressure device body.

[0010] Furthermore, the power source is a dry cell battery.

[0011] The working principle of this utility model:

[0012] The second insertion slot of this invention has a trigger end of a micro switch on its inner side wall. When the second connecting tube is inserted into the second insertion slot, the trigger end of the micro switch is pressed, the electrical connection inside the micro switch is disconnected, the air pump does not work, and the wall-mounted suction device directly provides negative pressure suction to the chest drainage bottle. When the second connecting tube is pulled out of the second insertion slot, the trigger end of the micro switch pops up, the electrical connection inside the micro switch is connected, thereby connecting the circuit to supply power to the air pump, causing the air pump to start. The air pump continuously draws air from the negative pressure port of the chest drainage bottle through the first connecting tube, thereby providing temporary negative pressure to the chest drainage bottle. This solves the technical problems of negative pressure drainage being interrupted due to the patient getting out of bed and moving, and negative pressure drainage being stopped for a long time due to forgetting to reinsert the negative pressure tube.

[0013] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0014] 1. The second connecting tube of this utility model is pulled out of the second insertion slot and the air pump is activated to provide temporary negative pressure for the chest drainage bottle.

[0015] 2. The tiger's mouth clamp of this utility model can fix the negative pressure device body to the chest drainage bottle, making it easy to carry.

[0016] 3. The sliding rheostat switch of this utility model can adjust the negative pressure.

[0017] 4. The indicator light of this utility model can indicate whether the air pump is operating. Attached Figure Description

[0024] The following embodiments will further illustrate the present invention, but do not limit the present invention.

[0025] like Figures 1 to 5 As shown, this embodiment provides a portable drainage-assisted negative pressure device, including a negative pressure device body 1, a first connecting tube 7, and a second connecting tube 8. The negative pressure device body 1 is connected to the negative pressure port of the chest drainage bottle 10 through the first connecting tube 7, and the negative pressure device body 1 is connected to the wall-mounted suction device 11 through the second connecting tube 8. The first connecting tube 7 and the second connecting tube 8 are also connected through the negative pressure device body 1, thereby connecting the negative pressure device body 1 in series between the chest drainage bottle 10 and the wall-mounted suction device 11 without affecting the original negative pressure suction effect of the wall-mounted suction device 11 on the chest drainage bottle 10.

[0026] The first insertion slot 101 and the second insertion slot 102 are located on the top of the negative pressure device body 1. The outer end of the first insertion slot 101 is inserted into one end of the first connecting tube 7, and the other end of the first connecting tube 7 is connected to the negative pressure port of the chest drainage bottle 10, thereby realizing the connection between the negative pressure device body 1 and the negative pressure port of the chest drainage bottle 10. The outer end of the second insertion slot 102 is inserted into one end of the second connecting tube 8, and the other end of the second connecting tube 8 is connected to the wall suction device 11, thereby realizing the connection between the negative pressure device body 1 and the wall suction device 11.

[0027] The negative pressure device body 1 contains a miniature air pump 2, a power supply 4, a switch 3, and a micro switch 9.

[0028] The air pump 2 has both its inlet and outlet ends located at the top. The inner end of the first insertion slot 101 is connected to the air pump 2's inlet end, and the inner end of the second insertion slot 102 is connected to the air pump 2's outlet end. This allows the first connecting tube 7 to connect to the air pump 2's inlet end through the first insertion slot 101, and the second connecting tube 8 to connect to the air pump 2's outlet end through the second insertion slot 102. The first connecting tube 7 and the second connecting tube 8 are also connected to each other through the air pump 2. This allows the wall suction device 11 to connect to the negative pressure port of the chest drainage bottle 10 in sequence through the second connecting tube 8, the air pump 2, and the first connecting tube 7. The drainage end of the chest drainage bottle 10 is connected to the human body 12, allowing the wall suction device 11 to provide negative pressure to the chest drainage bottle 10 for chest drainage in the same way as existing technologies.

[0029] A micro switch 9 is installed inside the negative pressure device body 1. The trigger end 901 of the micro switch 9 is located on the inner wall of the second insertion slot 102. The micro switch 9 is a normally closed contact. When the second connecting tube 8 is inserted into the second insertion slot 102, the tube wall of the second connecting tube 8 presses down the trigger end 901, thereby disconnecting the internal electrical connection of the micro switch 9, and the micro switch 9 is in the closed state. When the second connecting tube 8 is pulled out of the second insertion slot 102, the trigger end 901 pops up, thereby switching the micro switch 9 to the open state, and the internal electrical connection of the micro switch is connected.

[0030] Switch 3 is a sliding rheostat switch 3. The slider of switch 3 is set on the outer surface of the negative pressure device body 1. Sliding switch 3 can change the current, thereby adjusting the power of air pump 2 and thus adjusting the negative pressure.

[0031] An indicator light 5 is installed on the outer surface of the negative pressure device body 1 to indicate the working status of the air pump 2.

[0032] The power source 4 includes a battery box formed on the surface of the negative pressure device body 1, and two dry cell batteries are installed in the battery box. In other embodiments, the power source 4 may also be a lithium battery with a charging module.

[0033] The positive terminal of power supply 4, indicator light 5, switch 3, air pump 2, micro switch 9, and negative terminal of power supply 4 are connected in series. When both switch 3 and micro switch 9 are in the open state, the circuit is connected, power supply 4 supplies power to air pump 2 and indicator light 5, indicator light 5 lights up, air pump 2 starts to work, so that air pump 2 continuously pumps air to provide temporary negative pressure for chest drainage bottle 10. When either switch 3 or micro switch 9 is in the closed state, the circuit is broken, indicator light 5 goes out, and air pump 2 stops working.

[0034] A thumb clamp 6 is also installed on one side of the negative pressure device body 1. In this embodiment, the thumb clamp 6 is an elastic thumb clamp 6. The two clamping blocks of the thumb clamp 6 are connected to each other through an elastic slide rail, which can be adapted to chest drainage bottles 10 of different thicknesses. The negative pressure device body 1 is clamped to the side of the chest drainage bottle 10 by the thumb clamp 6, thereby achieving the effect of fixing the negative pressure device body 1 to the chest drainage bottle 10, which is convenient to carry and continuously provides negative pressure to the chest drainage bottle 10 when the patient gets out of bed and moves.

[0035] How to use this embodiment:

[0036] When in use, the first connecting tube 7 is inserted into the first insertion slot 101, the second connecting tube 8 is inserted into the second insertion slot 102, the negative pressure device body 1 is clamped to one side of the chest drainage bottle 10 by the thumb clamp 6, and the switch 3 is turned on to start use.

[0037] When the patient is not in bed, the wall suction device 11 is connected to the negative pressure port of the chest drainage bottle 10 in sequence through the second connecting tube 8, the air pump 2, and the first connecting tube 7, so that the wall suction device 11 provides negative pressure to the chest drainage bottle 10 for drainage in the same way as existing technology.

[0038] When the patient needs to get out of bed, the second connecting tube 8 is pulled out from the second insertion slot 102, the trigger end 901 of the micro switch 9 pops up, the micro switch 9 is turned on, the indicator light 5 lights up, and the air pump 2 starts to continuously pump air, thereby providing temporary negative pressure for the chest drainage bottle 10 and preventing the negative pressure from being interrupted when the patient gets out of bed.

[0039] After the patient returns to the bed, the second connecting tube 8 is reinserted into the second cannula slot 102. The trigger end 901 of the micro switch 9 is pressed down, the micro switch 9 is turned off, the indicator light 5 is turned off, and the air pump 2 stops working.

[0040] When medical staff make rounds, they can check whether the air pump 2 is working by observing whether the indicator light 5 is lit. If it is working, it may be because the patient has forgotten to insert the second connecting tube 8 back into the second insertion slot 102. They can help the patient insert it back in time to avoid the long-term loss of negative pressure affecting drainage.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
