Description

Technical Field

[0001] The utility model relates to a sputum suction device, in particular to a subglottic timing suction device for endotracheal intubation. Background Art

[0002] Endotracheal intubation is an important measure to rescue patients with respiratory dysfunction. This operation is a method of inserting a special endotracheal tube into the trachea or bronchus through the mouth or nasal cavity and the glottis. It is an important way to maintain airway patency, oxygen inhalation and carbon dioxide excretion.

[0003] However, the mouth's natural reaction to the insert produces a large amount of secretions, and patients with long-term intubation have reduced swallowing ability and need to be cleaned promptly.

[0004] Existing endotracheal tubes are already equipped with a special subglottic suction tube. After the patient is intubated, medical staff only need to connect the negative pressure suction device to the subglottic suction tube to perform a continuous negative pressure suction on the patient. However, continuous subglottic suction carries the risk of damage and bleeding of the respiratory mucosa above the airbag and below the glottis, which will accelerate the formation of sputum scabs on the surface of the respiratory mucosa. The reproduction of bacteria under the scabs aggravates mucosal inflammation, leading to respiratory mucosal bleeding. If an intermittent subglottic suction operation is performed on the patient, the above situation can be effectively avoided. However, in actual operation, medical staff have too many things to deal with in the ward, and it is difficult to accurately control the time. It is also very easy to make human errors and cause serious consequences.

[0005] In addition, the existing negative pressure suction is usually provided uniformly by the hospital's negative pressure system, which is unsustainable after leaving the ward, causing the suction operation to be terminated and aggravating the patient's aspiration.

[0006] Therefore, a timed subglottic suction device that can achieve intermittent subglottic suction, is safe and hygienic, and can be easily transferred with the bed has become an urgently needed product in clinical practice. Utility Model Content

[0007] In view of the above-mentioned shortcomings, the purpose of the utility model is to provide a subglottic timed suction device for endotracheal intubation, so as to achieve timed subglottic suction of patients and the timed subglottic suction device can be conveniently transferred with the bed.

[0008] In order to achieve the above object, the technical solution of the utility model is:

[0009] A subglottic timed suction device for endotracheal intubation, comprising

[0010] Support plate;

[0014] A negative pressure tank is installed on the support plate and has an opening opened upward, and the negative pressure pump is connected to the negative pressure tank;

[0015] The sputum suction component is connected to the sputum suction channel of the endotracheal tube. The sputum suction component is placed in a negative pressure tank and is compressed and inflated correspondingly when the pressure in the negative pressure tank increases or decreases.

[0016] Preferably, the sputum suction assembly includes a sealing cover, which is sealed on the opening of the negative pressure tank, and the sealing cover is connected to the bag body, and the bag body can be flattened and inflated and placed in the negative pressure tank.

[0021] Beneficial effects:

[0022] 1. This solution controls the negative pressure pump to rotate forward and backward at a fixed time through the control panel, controls the air pressure in the negative pressure tank to change at a fixed time, and then the sputum suction component in the negative pressure tank also changes in state of swelling and flattening, and the accumulated sputum attached to the endotracheal tube can be sucked out at a fixed time through the change in state of the sputum suction component. This solution is not only simple and smart in structure, and can be conveniently transferred with the patient, but also when the sputum suction component in this solution is performing the sputum suction operation, there is no direct contact between the sputum inside and the negative pressure tank, ensuring the hygienic safety of the reuse of the remaining components except the sputum suction component.

[0023] 2. The sputum suction component in this solution, through the softness of the bag body, can be flattened and inflated according to the increase and decrease of the air pressure in the negative pressure tank, and the sputum accumulated in the patient's respiratory tract can be sucked out through the inflation and flattening of the bag body.

[0024] 3. The sputum suction tube extends to the bottom of the bag body to ensure that the sucked sputum can be discharged at the bottom of the bag body, avoiding the sputum from being discharged through the air outlet pipe and causing contamination to other parts of this solution.

[0025] 4. Set a counterweight ball to ensure that the suction tube is always at the bottom of the bag.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 3 The endotracheal intubation subglottic timed suction device shown in the figure comprises a support plate 100, a battery 200 that can be repeatedly charged and discharged is installed at the bottom of the support plate, and a negative pressure pump 400 and a negative pressure tank 500 are installed on the upper surface of the support plate. The air inlet and outlet ports of the negative pressure pump are connected to the negative pressure tank.

[0034] It should also be noted that a control panel 300 is also mounted on the support plate 100, and the control panel is electrically connected to the battery and the negative pressure pump. The medical staff controls the interval time of each operation of the negative pressure pump through the adjustment button on the control panel.

[0035] In order to convert the regular pressure change in the negative pressure tank 500 into intermittent suction of the sputum accumulated in the patient's respiratory tract, a group of sputum suction components 600 are also arranged in the negative pressure tank. It should be noted that when the sputum suction component is placed in the negative pressure tank, the sputum suction component seals the upward opening of the negative pressure tank, thereby forming a closed space in which the positive and negative pressures can be controlled by the negative pressure pump.

[0036] Specifically, the sputum suction component has a one-way air inlet and outlet channel, the air inlet end of which is connected to the subglottic suction tube of the endotracheal tube, and the air outlet end is connected to the external atmosphere. When the negative pressure pump is working, the air pressure in the negative pressure tank shows a positive and negative pressure cycle conversion pattern through the forward and reverse rotation of the negative pressure pump. Specifically, when the negative pressure pump is reversed, the air pressure in the negative pressure tank is positive pressure. At this time, the sputum suction component is flattened by the positive pressure, and the internal gas is discharged. When the negative pressure pump rotates forward, the pressure in the negative pressure tank is negative pressure, and the atmosphere inside the sputum suction component swells and stretches the sputum suction component. At this time, the accumulated sputum in the patient's respiratory tract is sucked into the sputum suction component to achieve the purpose of sputum suction.

[0037] In this solution, the working interval of the negative pressure pump 400 can be set through the control panel to achieve the purpose of controlling the sputum suction interval.

[0038] It should be noted that, in this solution, the sputum suction assembly 600 specifically includes a sealing cover 630 that can be detachably fixed on the opening of the negative pressure tank 500. Specifically, the sealing cover can be implemented by threaded connection, snap connection, etc. A bag body 610 is connected to the lower surface of the sealing cover. It should be noted that the bag body is soft in texture, and after the sealing cover is sealed on the opening, the bag body is placed in the negative pressure tank 500.

[0039] In addition, an air outlet pipe 650 and a sputum suction pipe 670 are also provided on the sealing cover. Among them, a first one-way valve 640 is also provided on the air outlet pipe, and the first one-way valve has a one-way conduction from the inside of the bag body to the outside world, and a second one-way valve 660 is provided on the sputum suction pipe, and the second one-way valve is one-way conduction toward the inside of the bag body. It should be noted that in this scheme, the channel formed by the sputum suction pipe, the bag body, and the air outlet pipe is controlled by the second one-way valve and the first one-way valve to achieve one-way conduction from the sputum suction pipe to the air outlet pipe. At this time, when the bag body is flattened, the gas inside it is discharged to the outside world, and then when the bag body 610 is inflated, the air pressure inside the bag body is reduced and the accumulated sputum in the patient's trachea will be sucked out through the sputum suction channel connected to the sputum suction pipe 670.

[0040] It should be noted that in this solution, in order to prevent the sputum sucked out of the suction tube from being subsequently discharged to the outside through the exhaust pipe, one end of the suction tube located in the bag body extends to the bottom of the bag body 610 so that there is a height difference between the exhaust pipe and the suction tube.

[0041] In addition, in order to ensure that one end of the sputum suction tube 670 located in the bag body 610 can be kept at the bottom of the bag body, a counterweight ball 680 is also provided on the sputum suction tube.

[0042] It should be noted that in this solution, if the bag body is overly flattened, the sputum at the bottom of the bag body still has the risk of being discharged from the air outlet pipe. For this reason, a section of the tube body 620 is also provided between the sealing cover 630 and the bag body. Specifically, the tube body is made of a hard material so that when the negative pressure tank is under positive pressure, the tube body can still be in an open state, and the sputum squeezed up in the bag body will be temporarily retained in the tube body and avoid being discharged from the air outlet pipe.

[0043] In addition, it should be noted that a rubber plug 690 is also provided on the sealing cover, and both ends of the rubber plug are provided through the sealing cover, so that the needle tip of the syringe can pass through the rubber plug and inject some disinfectant with the function of inhibiting the growth of bacteria into the bag body.

[0044] Working principle: When the patient is intubated, the staff first inserts the flattened bag in the suction assembly into the negative pressure tank, and then fixes the sealing cover on the opening of the negative pressure tank to form a closed space. Subsequently, the subglottic suction tube of the tracheal intubation is connected to the suction tube in the suction assembly. Next, the operating frequency of the negative pressure pump is set through the control panel. After the above is completed, the negative pressure pump can be rotated through the gap to achieve the timed suction operation of the patient.

[0045] Specifically, when the negative pressure pump rotates forward, the air in the negative pressure tank is pumped out, and the interior is in a negative pressure state. At this time, the pressure difference between the bag and the interior of the negative pressure tank causes the bag to expand, and the bag sucks out the phlegm attached to the patient's trachea. As the negative pressure pump reverses, the pressure inside the negative pressure tank increases and is in a positive pressure state. At this time, the bag is flattened by the positive pressure, and the gas in the bag is discharged through the air outlet pipe. At this time, the bag is flattened to prepare for subsequent expansion. As the negative pressure pump rotates forward and backward during operation, the bag repeatedly expands and then flattens, and the phlegm in the patient's trachea is effectively sucked out.

[0046] It should be noted that, in the sputum suction component of the present invention, there is no direct contact between the part storing sputum inside and the negative pressure tank, so the safe use of the device can be ensured by simply replacing the sputum suction component, which is convenient and quick.
