Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an anti-blocking nursing drainage device for cardiothoracic surgery. Background Technique

[0002] Closed thoracic drainage is to place one end of the drainage tube into the thoracic cavity, and the other end is connected to a water seal bottle at a lower position to discharge gas or collect the liquid in the thoracic cavity, so that the lung tissue can reopen and resume its function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases;

[0003] Among them, the "nursing drainage device for cardiothoracic surgery" disclosed in the authorization number "CN202210235409.6" effectively solves the problem that it is very inconvenient to install and adjust during use, and it is not easy for patients to flexibly adjust according to the changes in the use occasion;

[0004] Although the cardiothoracic surgery nursing drainage device can drive the traction component to rotate after rotating the knob, and the traction component can drive the limit card to release the limit cooperation with the guide rail groove, so that it is convenient to slide the drainage device main body and the back cavity between the installation grooves to realize the function of flexibly adjusting the installation height of the drainage device main body. However, when the current cardiothoracic surgery drainage device is in use, if too much accumulated liquid in the liquid collection cavity is not drained in time, it is easy to overflow to other chambers through the communication port, increasing the pressure inside the thoracic cavity and causing difficulty in breathing. Moreover, the air pressure inside the liquid collection cavity increases continuously with thoracic drainage. When the staff is busy and does not release the air pressure and accumulated liquid in time, the device may show a reflux phenomenon, causing chest and lung infections, thereby aggravating the patient's condition.

[0005] In response to the problems in the related technology, no effective solution has been proposed yet. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a nursing drainage device for preventing blockage in cardiothoracic surgery, which has the following beneficial effects:

[0020] 1. The present invention collects the accumulated fluid from thoracic drainage through the liquid collection cavity. When the accumulated fluid in the liquid collection cavity accumulates too much and contacts the water level sensor, after the water level sensor senses the rising water level of the accumulated fluid, it transmits a signal to the first electric telescopic rod to contract its output end. At this time, the output end of the first electric telescopic rod drives the first sealing plate to move upward, so that the first sealing plate blocks the entrance of the second communication port. At the same time, the sealing strip contacts the edge of the second communication port to make its sealing performance better, avoiding the situation that when a large amount of accumulated fluid accumulates in the liquid collection cavity and the staff fails to handle it in time, the accumulated fluid easily overflows into the water seal cavity through the second communication port, resulting in an increase in the pressure inside the chest cavity and causing difficulty in breathing.

[0021] 2. When the second communication port of the present invention is automatically closed due to excessive liquid accumulation inside the liquid collection cavity, the second sealing plate is driven to automatically move upward through the connecting rod, so that the water outlet is opened, and the liquid accumulation inside the liquid collection cavity is automatically discharged, thereby continuously reducing the liquid accumulation inside the liquid collection cavity. When the liquid accumulation inside the liquid collection cavity decreases and it will not overflow to other chambers through the second communication port, the first electric telescopic rod drives the second sealing plate to move downward through the connecting rod to close the water outlet. At this time, the sealing ring contacts the rear end of the water outlet to make its sealing performance better, avoiding air leakage at the water outlet when the liquid collection cavity conducts cardiothoracic drainage, and solving the problem that when there is excessive liquid accumulation inside the liquid collection cavity, it cannot be discharged in time, which may cause reflux and lead to thoracic cavity infection.

[0022] 3. When too much liquid is drained from the liquid collection cavity of the present invention, the negative pressure inside the liquid collection cavity also increases accordingly. After detecting the negative pressure inside the liquid collection cavity through the air pressure monitoring table, a signal is transmitted to the second electric telescopic rod, causing the second electric telescopic rod to automatically contract, so that the air sealing cover flips and automatically opens. At this time, the air pressure inside the liquid collection cavity is automatically released through the air outlet, thereby reducing the negative pressure inside the liquid collection cavity, and avoiding the situation that after a large amount of liquid is collected inside the liquid collection cavity, the excessive negative pressure is likely to cause the liquid inside the liquid collection cavity to reflux into the thoracic cavity, resulting in thoracic cavity infection and aggravating the condition.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a nursing drainage device for preventing blockage in cardiothoracic surgery.

[0038] Please refer to Figures 1 - 12, A chest surgery anti-blockage nursing drainage device, including a closed thoracic drainage bottle main body 1, a liquid collection cavity 101, a water seal cavity 102 and a negative pressure adjustment cavity 103 arranged inside the closed thoracic drainage bottle main body 1. At the top inside the liquid collection cavity 101, a first communication port 104 is opened. Between the tops of the liquid collection cavity 101 and the water seal cavity 102, a second communication port 105 is opened. At the bottom inside the water seal cavity 102, a third communication port 106 is opened. At the top between the front end of the water seal cavity 102 and the negative pressure adjustment cavity 103, a fourth communication port 107 is opened;

[0039] On one side of the second communication port 105, a first sealing plate 2 is movably installed. On the top of the other side inside the liquid collection cavity 101, a first electric telescopic rod 201 fixedly connected to the first sealing plate 2 is fixedly installed. On one side of the first sealing plate 2, a cross bar 202 is fixedly connected. At the front end of the cross bar 202, a water level sensor 203 is fixedly installed. The first electric telescopic rod 201 and the water level sensor 203 are electrically connected. On the other side of the first sealing plate 2, a sealing strip 204 is fixedly connected. At the bottom of one end of the cross bar 202, a connecting rod 205 is fixedly installed. Outside the connecting rod 205, a support ring 206 fixedly connected to the inner wall of the liquid collection cavity 101 is sleeved and installed. At the bottom of the connecting rod 205, a second sealing plate 207 is fixedly connected. At the rear end of the closed thoracic drainage bottle main body 1, a water outlet 208 communicated with the liquid collection cavity 101 is fixedly installed. At the front end of the water outlet 208, a sealing ring 209 closely attached to the rear end of the second sealing plate 207 is fixedly installed;

[0040] On one side of the top of the closed thoracic drainage bottle main body 1, an air outlet 3 is opened through the liquid collection cavity 101. At the top of the air outlet 3, an air seal cover 301 is rotatably installed. On one side of the top of the closed thoracic drainage bottle main body 1, a second electric telescopic rod 302 rotatably connected to the top of the air seal cover 301 is rotatably installed. On the top of one side of the closed thoracic drainage bottle main body 1, a barometric pressure monitor 303 with the bottom end extending into the liquid collection cavity 101 is fixedly installed. The second electric telescopic rod 302 and the barometric pressure monitor 303 are electrically connected. At the bottom of the air outlet 3, an air outlet cover 304 is fixedly installed, and an odor removal sheet is arranged inside the air outlet cover 304.

[0041] Specifically, when the device drains the patient's chest cavity, the accumulated fluid flows into the interior of the liquid collection chamber 101 for collection. The accumulated fluid inside the liquid collection chamber 101 evenly flows into the three groups of chambers separated by the liquid collection chamber 101 through the first communication port 104 for collection. The gas flows into the interior of the water seal chamber 102 through the second communication port 105, and then flows into the front chamber through the third communication port 106 at the bottom of the water seal chamber 102. Then, the liquid level at the front end inside the water seal chamber 102 rises, and the negative pressure is transmitted to the interior of the negative pressure adjustment chamber 103 through the fourth communication port 107, causing the liquid level inside the negative pressure adjustment chamber 103 to rise and fall accordingly, facilitating the staff to observe the negative pressure intensity inside the device through the scale line 115, thereby facilitating the staff to adjust the negative pressure inside the device. When the liquid level of the accumulated fluid on the other side inside the liquid collection chamber 101 contacts the water level sensor 203 (the model of the water level sensor 203 is similar to PY201S, and the water level sensor 203 is electrically connected to the first electric telescopic rod 201, which is an existing technology in this field and will not be elaborated here), the water level sensor 203 transmits a signal to the first electric telescopic rod 201, causing the output end of the first electric telescopic rod 201 to start contracting, thereby driving the first sealing plate 2 to move upward, blocking the second communication port 105. At this time, the sealing strip 204 closely fits with the edge of the second communication port 105 to improve the sealing performance, preventing the accumulated fluid from flowing into the interior of the water seal chamber 102 through the second communication port 105. At the same time, the output end of the first electric telescopic rod 201 drives the second sealing plate 207 to move upward through the cross bar 202 and the connecting rod 205. The connecting rod 205 slides upward more stably inside the support ring 206. At this time, the outlet of the water outlet 208 is opened, enabling the accumulated fluid inside the liquid collection chamber 101 to be discharged through the water outlet 208 for centralized treatment. As the volume of the accumulated fluid inside the liquid collection chamber 101 changes, the pressure inside the liquid collection chamber 101 is monitored by the air pressure monitoring table 303. When the negative pressure inside the liquid collection chamber 101 increases, the air pressure monitoring table 303 transmits a signal to the second electric telescopic rod 302, causing the output end of the second electric telescopic rod 302 to contract and drive the air seal cover 301 to open. At this time, the air pressure inside the liquid collection chamber 101 is released through the air outlet 3, and the gas passes through the air outlet cover 304. The odor removal sheet inside is made of activated carbon material and has a strong adsorption capacity, which can effectively adsorb odor molecules, bacterial metabolites, and harmful gases such as formaldehyde and ammonia in the air to remove odors, avoiding strong odors when the gas is discharged and affecting other patients. After the gas is released, the continuously increasing negative pressure inside the liquid collection chamber 101 is effectively reduced, solving the problem that when a large amount of accumulated fluid accumulates inside the liquid collection chamber 101 and the staff fails to handle it in time, the accumulated fluid easily overflows into the interior of the water seal chamber 102 through the second communication port 105, resulting in an increase in the pressure inside the chest cavity, leading to difficulty in breathing, and the increase in the negative pressure inside the device may cause reflux, leading to chest cavity infection and aggravating the condition.

[0042] Further, at the top of the other side of the rear end of the closed thoracic drainage bottle main body 1, a first water inlet 109 that is connected to the water seal chamber 102 in a through manner is provided. On the other side of the top of the closed thoracic drainage bottle main body 1, a second water inlet 110 that is connected to the negative pressure adjustment chamber 103 in a through manner is provided. A sealing cover 111 is rotatably installed at the top of the second water inlet 110, and a water injection switch 112 is rotatably installed at the rear end of the first water inlet 109. Scale lines 115 are evenly arranged at the front end of the closed thoracic drainage bottle main body 1, and hooks 7 are rotatably installed on both sides of the closed thoracic drainage bottle main body 1.

[0043] Specifically, the staff can add sterile normal saline into the interior of the water seal chamber 102 through the first water inlet 109 by opening the water injection switch 112 for water seal operation. By opening the sealing cover 111, it is convenient for the staff to add sterile normal saline into the interior of the negative pressure adjustment chamber 103 through the second water inlet 110. It is convenient for the staff to observe the negative pressure intensity inside the device through the scale lines 115 of the observation window and thus perform appropriate pressure adjustment operations. By rotating the hook 7 upward, it is convenient for the hook 7 to drive the closed thoracic drainage bottle main body 1 to hang on one side of the hospital bed to maintain a specified height for drainage operation.

[0044] Further, on the other side of the rear end of the closed thoracic drainage bottle main body 1, a buckle 113 located at the top of the first water inlet 109 is fixedly installed, and a limit hole 114 is provided at the top of the rear end of the water injection switch 112.

[0045] Specifically, when the water injection switch 112 is closed to close the inlet of the first water inlet 109, the buckle 113 slides into the interior of the limit hole 114 for limitation, so that the limit hole 114 is fixed outside the first water inlet 109 for sealing, avoiding air leakage of the device.

[0046] Further, on one side of the top of the closed thoracic drainage bottle main body 1, a thoracic connection port 4 is fixedly installed in a through manner. A corrugated pipe 401 is sleeved at the top of the thoracic connection port 4. One end of the corrugated pipe 401 is fixedly connected to a connecting pipe 402. One end of the connecting pipe 402 is fixedly connected to a protective sleeve 403 through a silicone tape. On the other side of the top of the closed thoracic drainage bottle main body 1, a negative pressure regulating valve 5 is fixedly installed, and a negative pressure connection port 501 is connected to the top of the negative pressure regulating valve 5 in a through manner.

[0047] Specifically, the connecting pipe 402 is connected to the top of the thoracic cavity connection port 4 through the corrugated pipe 401. The corrugated pipe 401 has a certain flexibility, so that the connecting pipe 402 will not wrinkle when stretched and turned. Moreover, a lubricating layer is applied inside the connecting pipe 402 to prevent blockage when the effusion is drained through the connecting pipe 402. When the connecting pipe 402 is not connected and in use, one end of the connecting pipe 402 is sleeved with a protective sleeve 403 for protection, preventing external bacteria from entering the inside of the connecting pipe 402 and easily causing bacterial infection to the patient's thoracic cavity. The pressure regulating pipe is connected through the negative pressure connection port 501, which facilitates the staff to rotate the negative pressure regulating valve 5 to adjust the negative pressure intensity inside the liquid collecting cavity 101 and prevent the occurrence of backflow caused by the increase of negative pressure inside the device.

[0048] Further, a sampling groove 6 communicating with the liquid collecting cavity 101 is opened on one side of the rear end of the thoracic cavity closed drainage bottle main body 1, and a rubber plug 601 is movably installed inside the sampling groove 6;

[0049] Specifically, the rubber plug 601 is placed inside the sampling groove 6 for sealing. When the effusion is collected inside the liquid collecting cavity 101, the staff inserts the needle of the medical syringe through the rubber plug 601 into the liquid collecting cavity 101 to extract the effusion, which facilitates the staff to sample and detect the effusion.

[0050] Further, storage grooves 108 are opened on both sides of the bottom of the thoracic cavity closed drainage bottle main body 1. Suction cups 8 are arranged on both sides of the bottom of the thoracic cavity closed drainage bottle main body 1 and are located inside the storage grooves 108. A fixing rod 801 fixedly connected to the top of the storage groove 108 is movably installed inside the suction cup 8. A limiting plate 802 is fixedly installed at the bottom of the outside of the suction cup 8. A spring 803 located on the top of the limiting plate 802 is sleeved on the top of the outside of the suction cup 8. A rotating plate 9 is rotatably installed at the bottom of the thoracic cavity closed drainage bottle main body 1. Support side plates 901 are movably installed at the front end and the rear end of the rotating plate 9. Through grooves 902 are opened on both sides inside the rotating plate 9. Slide rods 903 fixedly connected to the support side plates 901 are movably installed inside the through grooves 902, and the two slide rods 903 on both sides are arranged staggeredly. A sliding groove 904 is opened inside the slide rod 903, and a slider 905 fixedly connected to the inner wall of the through groove 902 is slidably installed inside the sliding groove 904;

[0051] Specifically, when the device needs to be placed on the ground for use, rotate the rotating plate 9 to make the supporting side plate 901 in a vertical state, and then pull the supporting side plate 901. At this time, the sliding rod 903 moves outward inside the through groove 902, and the slider 905 slides inside the sliding groove 904, so that the supporting side plate 901 is stretched and expanded to both sides, increasing the contact area with the ground. At the same time, under the elastic force of the spring 803, the suction cup 8 slides downward and elongates on the outside of the fixed rod 801, so that the bottom of the suction cup 8 can be adsorbed on the ground for fixation, so that the main body 1 of the closed thoracic drainage bottle can be placed on the ground more stably, avoiding the situation that the main body 1 of the closed thoracic drainage bottle is accidentally kicked by passing personnel and causing it to fall over.

[0052] Further, the front end and the rear end of the bottom of the main body 1 of the closed thoracic drainage bottle are rotatably installed with a knob 906, and a convex block located outside the supporting side plate 901 is arranged at the bottom of the knob 906;

[0053] Specifically, when the supporting side plate 901 is received at the front end and the rear end of the rotating plate 9, rotate the knob 906 to make the convex block at its bottom move to the bottom end to limit the supporting side plate 901. At the same time, the suction cup 8 is received inside the receiving groove 108 and blocked by the supporting side plate 901, avoiding the situation that the supporting side plate 901 automatically bounces open when the main body 1 of the closed thoracic drainage bottle is suspended, causing the suction cup 8 to slide out of the receiving groove 108 and making it inconvenient to suspend the main body 1 of the closed thoracic drainage bottle.

[0054] Working principle: First, the staff opens the sealing cover 111 and the water injection switch 112, adds sterile normal saline into the inside of the water seal cavity 102 and the negative pressure adjustment cavity 103 through the first water inlet 109 and the second water inlet 110, and then closes the sealing cover 111 and the water injection switch 112 for sealing. Then, connect the connecting pipe 402 to the top of the thoracic cavity connection port 4 through the corrugated pipe 401. Then, open the protective sleeve 403 to connect the connecting pipe 402 with the drainage tube. Subsequently, connect it to the pressure regulating device through the negative pressure connection port 501. Then, perform thoracic cavity drainage treatment. The accumulated fluid or gas inside the patient's thoracic cavity is drained through the connecting pipe 402 and collected inside the liquid collection cavity 101. The gas flows into the inside of the water seal cavity 102 through the first communication port 104 and the second communication port 105, causing the front end of the water seal liquid level to rise. The gas flows into the inside of the negative pressure adjustment cavity 103 through the fourth communication port 107 and increases the negative pressure inside the negative pressure adjustment cavity 103. Under the action of the negative pressure, the liquid level inside the other chamber of the negative pressure adjustment cavity 103 rises accordingly. The staff can conveniently observe the liquid level height inside the negative pressure adjustment cavity 103 by observing the scale line 115. When the liquid level inside the other chamber of the negative pressure adjustment cavity 103 reaches the maximum fixed value, the staff rotates the negative pressure regulating valve 5 to adjust the negative pressure intensity inside the negative pressure adjustment cavity 103, and releases the negative pressure through the negative pressure connection port 501, thereby controlling the air pressure intensity inside the main body 1 of the closed thoracic drainage bottle and avoiding the situation of backflow due to excessive gas pressure inside the liquid collection cavity 101. When the accumulated liquid level inside the other side of the liquid collection cavity 101 touches the water level sensor 203, the water level sensor 203 transmits a signal to the first electric telescopic rod 201, causing the output end of the first electric telescopic rod 201 to start contracting, thereby driving the first sealing plate 2 to move upward and block the second communication port 105. At this time, the sealing strip 204 is closely attached to the edge of the second communication port 105 to improve the sealing performance and prevent the accumulated liquid from flowing into the inside of the water seal cavity 102 through the second communication port 105. At the same time, the output end of the first electric telescopic rod 201 drives the second sealing plate 207 to move upward through the cross bar 202 and the connecting rod 205. The connecting rod 205 slides upward more stably inside the support ring 206. At this time, the outlet of the water outlet 208 is opened, and the accumulated liquid inside the liquid collection cavity 101 is discharged through the water outlet 208 for centralized treatment. As the volume of the accumulated liquid inside the liquid collection cavity 101 changes, the pressure inside the liquid collection cavity 101 is monitored through the air pressure monitoring table 303. When the negative pressure inside the liquid collection cavity 101 increases, the air pressure monitoring table 303 transmits a signal to the second electric telescopic rod 302, causing the output end of the second electric telescopic rod 302 to contract and drive the air sealing cover 301 to open. At this time, the air pressure inside the liquid collection cavity 101 is released through the air outlet 3, and the gas is deodorized by the deodorizing sheet inside the air outlet cover 304. After the gas is released, the continuously increasing negative pressure inside the liquid collection cavity 101 is effectively reduced.

[0055] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
