Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a multifunctional blowing and suction device. Background Art

[0002] At present, video laryngoscopes can be roughly divided into two forms, one is free open type, and the other is portable type. In the free open type video laryngoscope, the endotracheal tube and the laryngoscope are not connected. Usually, the laryngoscope is first inserted into the patient's mouth, and after observing the glottis, the endotracheal tube is inserted into the patient's airway along the direction of the video laryngoscope. Usually, a shapeable guide wire (tube core) is used to shape the endotracheal tube for easy operation. However, sometimes, the patient's glottis is well exposed, but endotracheal intubation is difficult to succeed. This is what we call a difficult airway. The portable type video laryngoscope has a tube cavity for carrying the endotracheal tube on one side of the video laryngoscope. When performing endotracheal intubation, a suitable type of endotracheal tube can be placed in the tube cavity in advance, and the endotracheal tube can be inserted into the patient's mouth together with the video laryngoscope. After observing the patient's glottis, the endotracheal tube pre-placed in the tube cavity is pushed forward and inserted into the patient's airway.

[0003] However, the above-mentioned video laryngoscope does not have a preset channel for placing suction and flushing pipes, and the conventional suction tube can only be inserted along it to the vicinity of the lens at the front end of the video laryngoscope. Since these suction tubes cannot be fixed in the mouth and are unstable with the video laryngoscope, the front end of the suction tube may move around in the mouth, and the position of the suction port cannot be fixed, which is easy to affect the smooth progress of tracheal intubation; another suction method is that a second medical staff member inserts a rigid suction tube with a special curvature (not related to the video laryngoscope) into the patient's mouth for suction. When using this type of suction tube, it is usually necessary to reach the lowest point of the respiratory tract of the patient in the supine position. The patient's gastric contents reflux, secretions or blood from the nose or throat accumulate here, which is easy to block the suction tube. If the operator cannot find it in time, these secretions or blood cannot be sucked out in time, and will quickly reach and enter the throat, thereby obstructing the line of sight of tracheal intubation, making the success of airway management more difficult or even impossible; in addition, gastric acid entering the lungs can cause severe respiratory failure, which poses a serious safety hazard to patients.

[0004] Therefore, it is necessary to provide a multifunctional blowing and suction device to assist the visual laryngoscope to clear the fluid accumulated in the patient's throat and ensure the smooth progress of endotracheal intubation. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the application and with reference to the accompanying drawings.

[0025] In a specific implementation, the visual laryngoscope can refer to a double-lens combination visual laryngoscope device disclosed in Chinese invention patent application number CN202211443593.X.

[0026] like Figure 1 As shown, a multifunctional blowing and suction device comprises: a receiving groove 1;

[0027] A control platform 3 disposed at the upper end of the accommodating groove 1;

[0028] At least one plastic hose 6 connected to the control platform 3, the plastic hose 6 is arranged in close contact with the accommodating groove 1, and the hose opening 7 at the other end of the plastic hose 6 extends to the lower end of the accommodating groove 1;

[0029] A vacuum pressure indicator 4 and an external interface 5 communicated with the control platform 3;

[0030] An alarm device 9 is arranged on the control platform 3, and the alarm device 9 is electrically connected to the vacuum pressure indicator 4;

[0031] A locking device is provided on the accommodating groove 1, and the locking device is used to lock the accommodating groove 1 and the video laryngoscope.

[0032] like Figure 1-2 As shown, the locking device includes a snap-fit ​​portion 2 and a locking structure 8, wherein the snap-fit ​​portion 2 is located between the accommodating groove 1 and the control platform 3, and the snap-fit ​​portion 2 is used to be mounted on the video laryngoscope; the locking structure 8 is located at the lower end of the accommodating groove 1, and the locking structure 8 is used to cooperate with the lower end of the video laryngoscope.

[0033] Preferably, the buckle part 2 is adapted to the size of the video laryngoscope, or an elastic annular component is sleeved on the upper end of the video laryngoscope, and the locking structure 8 is matched with the lower end of the video laryngoscope, and a snap fit or an interference fit can be adopted. After the buckle part 2 and the locking structure 8 are matched with the video laryngoscope, the multifunctional blowing and suction device is fixed on the video laryngoscope;

[0034] The locking structure 8 and the buckle part 2 in the functional blowing and suction device and the visual laryngoscope device can realize the rapid disassembly and assembly of the multifunctional blowing and suction device and the visual laryngoscope device, and can ensure the stability of the two after cooperation, so as to avoid the multifunctional blowing and suction device accidentally falling off the visual laryngoscope device during use, causing safety hazards; and the rapid disassembly and assembly of the two also makes it convenient to disassemble and discard the multifunctional blowing and suction device after use and to disinfect the visual laryngoscope device, thereby reducing the cost of medical equipment during patient examination and treatment.

[0035] like Figure 1 As shown, the control platform 3 and the vacuum pressure indicator 4 are provided with a communicating vent hole 10 , and the vent hole 10 is provided with a pluggable hole plug.

[0036] In actual use, if sputum suction is required for the patient, the external interface 5 of the multifunctional blowing and suction device should be connected to the vacuum pump of the medical unit; if oxygen is required for the patient, the external interface 5 of the multifunctional blowing and suction device should be connected to the oxygen source of the medical unit; if targeted medicine delivery is required for the patient, the external interface 5 of the multifunctional blowing and suction device should be connected to the drug delivery device;

[0037] If the patient needs to suction phlegm, the plug of the vent hole 10 on the multifunctional blowing and suction device should be removed, so that the operator can open / close the vent hole 10 with his thumb to control the suction process.

[0038] If oxygen or medicine is to be given to the patient, the vent hole 10 on the multifunctional blowing and suction device should be tightly covered with a hole plug so that oxygen or medicine can be directly delivered to the hose opening 7 through the plastic hose 6 to complete oxygen supply or directional medicine delivery. Once the plastic hose 6 of the multifunctional blowing and suction device is used for sputum suction operation, it can no longer be used for oxygen supply or directional medicine delivery. Usually, oxygen supply and directional medicine delivery are required at the beginning of the endotracheal intubation process. The channel used for oxygen supply or directional medicine delivery can still be used for sputum suction operation later.

[0039] In some extreme cases, the sputum suction channel of the multifunctional blowing and suction device may be blocked by food residues of gastric reflux or blood clots coagulated in the patient's oral cavity, interrupting the smooth progress of the sputum suction operation. If the plastic hose 6 of the multifunctional blowing and suction device is blocked, and the vacuum pump for sputum suction is still working, the negative pressure of the sputum suction channel will increase, and the pointer of the vacuum pressure indicator 4 for monitoring the vacuum pressure of the sputum suction channel will point to the negative pressure side. When the negative pressure of the sputum suction channel reaches a certain level, the alarm 9 will be activated to start emitting a "beep" sound alarm to remind medical staff that the sputum suction channel is not smooth or blocked, and it is necessary to clear it immediately to prevent the secretions in the patient's oral cavity from accumulating and causing irreversible medical damage to the patient, such as food residues or gastric acid or other secretions of the patient's gastric reflux, which can not be discharged from the body in time and mistakenly enter the patient's respiratory tract, which may cause severe respiratory failure in the patient, and there are serious safety hazards.

[0040] In addition to the visual display of the pressure indication of the vacuum pressure indicator 4 and the alarm display of the alarm 17, a sound-generating device can be arranged at the connection between the plastic hose 6 and the control platform 3. When fluid passes through the plastic hose 6, the sound-generating device can emit a prompt sound, and the prompt sound changes with the flow rate, so that the operator can intuitively feel the operation of the multifunctional suction device, and when the plastic hose 6 is gradually blocked, the prompt sound gradually disappears, and the operator can discover the blockage more promptly, strive for remedial time, and reduce safety hazards.

[0041] like Figure 1 As shown, the lower end of the accommodating groove 1 is provided with an escape groove, which is used to avoid the hose opening 7. The escape groove is used to avoid the hose opening 7, which can ensure that the accommodating groove 5 will not block the hose opening 7 when the hose opening 7 is used for suctioning sputum, oxygen delivery or directional drug delivery.

[0042] like Figure 2 As shown, the shape of the receiving groove 1 is adapted to the shape of the video laryngoscope. In the actual use of the multifunctional blowing and suction device, the receiving groove 1 is adapted to the shape and size of the matching video laryngoscope, and fits the video laryngoscope, so as to minimize the increase in the volume of the video laryngoscope and reduce the difficulty of inserting the video laryngoscope into the patient's throat.

[0043] In a specific embodiment, the accommodating groove 1 and the plastic hose 6 are both made of transparent material. This prevents the multifunctional blowing and suction device from affecting the imaging of the video laryngoscope. Even if the multifunctional blowing and suction device slightly blocks the imaging of the video laryngoscope, the operator can roughly judge the image of the blocked part, thereby preventing the operator from missing the key part image.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
