Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to a disposable visualized sputum suction device. Background Art

[0002] The main function of the suction device is to effectively clean the airway and large amounts of sputum secretions, or vomitus that is accidentally inhaled into the airway. The working principle is mainly to generate negative pressure to smoothly suck out the secretions in the airway, relieve airway obstruction, and restore respiratory patency.

[0003] At present, the suction devices on the market are operated by doctors and nurses who rely on their experience to insert the suction tube into the patient's mouth and nose. Since it is a blind insertion operation, it is easy to cause mucosal damage, and it is easy to touch the damaged part and increase the patient's pain. The sputum cannot be completely sucked out. Although the existing suction devices are also equipped with visual probes, the structure is relatively complex, the cost is high and the loss is large.

[0004] For this reason, we use this technical solution to solve the problem that the existing sputum suction device cannot be visually operated. Summary of the invention

[0005] The purpose of the present invention is to improve the suction device in the prior art. Compared with the prior art, a disposable visual suction device is provided. A miniature camera is added to the existing suction device for visual operation. Under the visual operation, the airway condition is clear at a glance, and the condition of the patient's nasal cavity and airway can be observed in real time, effectively avoiding the problem of mucosal damage caused by blind suction. At the same time, it also avoids repeated suction at the same site. It is highly targeted and can directly avoid the damaged site. In addition, the cooperation of the medicine dropper can effectively improve the patient's discomfort. In addition, an adaptive tracheal dilator is added to the front end of the suction tube to dilate the trachea, which further effectively helps suction, and relies on the negative pressure suction effect to allow the adaptive tracheal dilator to adaptively expand with the size of the negative pressure value, so that it can adapt to the trachea of ​​adults and children, effectively avoiding damage to the trachea of ​​children.

[0006] Realizing visual operation of suction can effectively improve the efficiency of suction, and can also adaptively adapt to the trachea of ​​adults and children.

[0007] As a further improvement of the present application, the adaptive tracheal dilator comprises two inner and outer telescopic layers, and the inner and outer telescopic layers form a closed space. The two telescopic layers themselves have elasticity. In the initial state, the telescopic layers stretch freely. At this time, the adaptive tracheal dilator does not expand the trachea. When suctioning begins, the suction effect of negative pressure draws out the air in the closed space surrounded by the two telescopic layers. Under the action of this negative pressure, the telescopic layers contract and the adaptive tracheal dilator expands. At this time, the adaptive tracheal dilator expands the trachea.

[0008] As a further improvement of the present application, the telescopic layer is an annular corrugated structure, and the telescopic layer is made of medical elastic silicone. The annular corrugated structure enables the telescopic layer to be telescopic. The telescopic layer is in an extended state in the initial state, and the adaptive tracheal dilator does not dilate the trachea at this time. Under a negative pressure state, the telescopic layer is in a contracted state, and the adaptive tracheal dilator dilates the trachea at this time. The use of medical silicone ensures that the adaptive tracheal dilator will not damage the trachea in the morning.

[0009] As a further improvement of the present application, a plurality of telescopic guide rings are fixedly connected to the interior of the telescopic layer, the telescopic guide ring comprises a bending body, and a plurality of groups of embedded bodies which are equally spaced and distributed around the inner wall of the bending body are fixedly inlaid, the telescopic guide ring plays a role of guiding the bending, and the elastic force of the bending body enables itself to bend but not be flattened, so that when negative pressure is generated, the enclosed space surrounded by the two telescopic layers will not become deflated due to the gas being sucked away, and under the action of negative pressure, the two telescopic layers will contract and squeeze each other in order to empty the internal gas, and at this time the bending body will bend along the radial direction, so that the adaptive tracheal dilator will contract and expand, thereby playing a role of expanding the trachea, and the embedded body plays a role of shaping the bending body, and at the same time, the embedded body relies on its own elastic force to balance the negative pressure suction, so that the telescopic guide ring can adaptively adjust the degree of curvature according to the size of the negative pressure value, so that the adaptive tracheal dilator can adapt to the trachea of ​​adults and children.

[0010] As another improvement of the present application, the bending body is an annular porous structure, and the bending body is made of elastic material. In order to allow the gas between the two telescopic layers to be sucked away, the bending body adopts a porous structure to make the internal parts of the adaptive tracheal dilator connected. The elastic force of the bending body can make the adaptive tracheal dilator quickly restore its shape after the negative pressure disappears, effectively preventing the adaptive tracheal dilator from scratching the trachea when the suction tube is pulled out.

[0011] As another improvement of the present application, a scale line is provided on the side wall of the end of the suction tube away from the sputum storage tube, and the scale line has a scale range of 0-30 cm. In view of the different requirements for the insertion depth of nasal and oral suction, the scale line marking directly reminds the operator whether the depth meets the operation requirements, effectively avoiding the situation where the suction tube is inserted too shallowly and the sputum is not suctioned properly, and the suction tube is inserted too deeply, aggravating the patient's mucosal damage.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] (1) This scheme adds a miniature camera to the existing suction device for visual operation. Under the visual operation, the airway condition is clear at a glance, and the condition of the patient's nasal cavity and airway can be observed in real time, effectively avoiding the problem of mucosal damage caused by blind suction. At the same time, it also avoids repeated suction at the same site. It is highly targeted and can directly avoid damaged sites. In addition, the cooperation of the dropper can effectively improve the patient's discomfort. In addition, an adaptive tracheal dilator is added to the front end of the suction tube to dilate the trachea, which further effectively helps suction. The negative pressure suction effect allows the adaptive tracheal dilator to expand adaptively with the size of the negative pressure value, so that it can adapt to the trachea of ​​adults and children, effectively avoiding damage to the trachea of ​​children, and realizing the visual operation of suction. It can effectively improve the suction efficiency and can also adaptively adapt to the trachea of ​​adults and children.

[0014] (2) The adaptive tracheal dilator includes two inner and outer telescopic layers, and the two inner and outer telescopic layers enclose a closed space. The two telescopic layers themselves have elasticity. In the initial state, the telescopic layers are freely stretched out. At this time, the adaptive tracheal dilator does not dilate the trachea. When suctioning begins, the suction effect of negative pressure draws out the air in the closed space enclosed by the two telescopic layers. Under the action of this negative pressure, the telescopic layers contract and the adaptive tracheal dilator expands. At this time, the adaptive tracheal dilator has a dilating effect on the trachea.

[0015] (3) The telescopic layer is an annular corrugated structure, and the telescopic layer is made of medical elastic silicone. The annular corrugated structure enables the telescopic layer to be telescopic. The telescopic layer is in an extended state in the initial state, and the adaptive tracheal dilator does not dilate the trachea at this time. In the negative pressure state, the telescopic layer is in a contracted state, and the adaptive tracheal dilator dilates the trachea at this time. The use of medical silicone ensures that the adaptive tracheal dilator will not damage the trachea in the morning.

[0016] (4) The interior of the telescopic layer is fixedly connected with a plurality of telescopic guide rings, the telescopic guide rings include a bending body, and the inner wall of the bending body is fixedly inlaid with a plurality of groups of embedded bodies distributed around with equal intervals. The telescopic guide rings play a role in guiding the bending. The elastic force of the bending body allows it to bend but not be flattened. In this way, when negative pressure is generated, the enclosed space surrounded by the two telescopic layers will not become deflated due to the gas being sucked away. Under the action of negative pressure, the two telescopic layers contract and squeeze each other in order to empty the internal gas. At this time, the bending body bends along the radial direction, so that the adaptive tracheal dilator contracts and expands, thereby playing a role in expanding the trachea. The embedded body plays a role in shaping the bending body. At the same time, the embedded body relies on its own elastic force to balance the negative pressure suction. In this way, the telescopic guide ring can adaptively adjust the degree of curvature according to the size of the negative pressure value, so that the adaptive tracheal dilator can adapt to the trachea of ​​adults and children.

[0017] (5) The bending body is a ring-shaped porous structure, and the bending body is made of elastic material. In order to allow the gas between the two telescopic layers to be sucked away, the bending body adopts a porous structure to make the internal parts of the adaptive tracheal dilator connected. The elastic force of the bending body can make the adaptive tracheal dilator quickly restore its shape after the negative pressure disappears, effectively preventing the adaptive tracheal dilator from scratching the trachea when the suction tube is pulled out.

[0018] (6) A scale line is set on the side wall of the suction tube away from the sputum storage tube, and the scale line range is 0-30cm. In view of the different insertion depth requirements for nasal and oral suction, the scale line mark directly reminds the operator whether the depth meets the operation requirements, effectively avoiding the situation where the suction tube is inserted too shallowly and the sputum is not sucked in place, and the suction tube is inserted too deeply, which aggravates the patient's mucosal damage.

DETAILED DESCRIPTION

[0029] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0030] A disposable visual suction device, see Figure 1 , 2 and Figure 3 , including a sputum storage tube 1, the upper end of the sputum storage tube 1 is connected with a negative pressure connecting tube 2 and a sputum suction tube 3, and the negative pressure connecting tube 2 is connected with the negative pressure device, and a scale line 9 is also arranged on the side wall of the end of the sputum suction tube 3 away from the sputum storage tube 1, and the scale range of the scale line 9 is 0-30cm, and the requirements for the insertion depth of nasal and oral sputum suction are different, and the scale line 9 is used to directly remind the operator whether the depth meets the operation requirements, effectively avoiding the situation that the sputum suction tube 3 is inserted too shallowly and the sputum suction is not in place and the sputum suction tube 3 is inserted too deeply, which aggravates the patient's mucosal damage, and a medicine drop port 4 is opened on the side wall of the end of the sputum suction tube 3 away from the sputum storage tube 1, and a medicine dropper 5 is penetrated inside the sputum suction tube 3, and the medicine dropper 5 extends from the inside of the sputum suction tube 3 through the medicine dropper port 4 to the outside, and an adaptive tracheal dilator 6 is connected to the end of the sputum suction tube 3 away from the sputum storage tube 1;

[0031] See also Figure 4 , 5 , 6 and Figure 7 The adaptive tracheal dilator 6 includes two inner and outer telescopic layers 601, and the inner and outer telescopic layers 601 enclose a closed space. The two telescopic layers 601 have elasticity. In the initial state, the telescopic layers 601 are freely stretched. At this time, the adaptive tracheal dilator 6 does not dilate the trachea. When sputum suction begins, the suction effect of negative pressure draws out the air in the closed space enclosed by the two telescopic layers 601. Under the action of this negative pressure, the telescopic layers 601 contract to expand the adaptive tracheal dilator 6. At this time, the adaptive tracheal dilator The expander 6 has an expansion effect on the trachea. The expansion layer 601 is an annular corrugated structure, and the expansion layer 601 is made of medical elastic silicone. The annular corrugated structure enables the expansion layer 601 to expand and contract. The expansion layer 601 is in an expanded state in the initial state. At this time, the adaptive tracheal expander 6 does not expand the trachea. In the negative pressure state, the expansion layer 601 is in a contracted state. At this time, the adaptive tracheal expander 6 expands the trachea. The use of medical silicone ensures that the adaptive tracheal expander 6 will not damage the trachea in the morning.

[0032] See also Figure 3, and a ventilation connection plate 8 is fixedly connected between the upper end of the adaptive tracheal dilator 6 and the sputum suction tube 3, the interior of the ventilation connection plate 8 is connected to the interior of the adaptive tracheal dilator 6, and the side wall of the ventilation connection plate 8 is provided with a plurality of vent holes 801 which are equally spaced and distributed around and connected to the interior of the sputum suction tube 3, the interior of the sputum suction tube 3 is also penetrated by a miniature camera 7, and the miniature camera 7 passes through the interior of the sputum suction tube 3 and extends to the front end of the adaptive tracheal dilator 6, the miniature camera 7 is located in the middle position of the adaptive tracheal dilator 6, and the miniature camera 7 is bonded to the inner wall of the sputum suction tube 3 through a bracket (the bonding connection is to facilitate the miniature camera 7 from The sputum suction tube 3 is taken out to facilitate replacement of a new sputum suction tube 3), the medicine dropper 5 and the miniature camera 7 are both inserted through the lower end of the sputum storage tube 1, and the lower end side wall of the sputum storage tube 1 is fixedly inlaid with a sealing penetration sleeve matching the medicine dropper 5 and the miniature camera 7. The function of the sealing penetration sleeve is to tightly wrap the medicine dropper 5 and the miniature camera 7 when they are inserted, so as to achieve sealing at the insertion point to avoid air leakage and insufficient negative pressure. The specific structure of the sealing penetration sleeve is a circular rubber diaphragm, and a perforation is provided on the circular rubber diaphragm. After the medicine dropper 5 and the miniature camera 7 are inserted through the perforation, the circular rubber diaphragm relies on its own elastic force to tightly wrap the medicine dropper 5 and the miniature camera 7.

[0033] Based on Example 1, please refer to Figure 7 , 8 The telescopic layer 601 is internally fixedly connected with a plurality of telescopic guide rings 602, the telescopic guide rings 602 include a curved body 6021, and the inner wall of the curved body 6021 is fixedly inlaid with a plurality of embedded bodies 6022 (preferably made of polyurethane elastic material, and other materials can also be selected according to actual needs) that are equally spaced and distributed around. The telescopic guide rings 602 play a role in guiding the bending, and the elastic force of the curved body 6021 makes it only bendable and cannot be flattened. In this way, when negative pressure is generated, the enclosed space enclosed by the two layers of telescopic layers 601 will not become deflated due to the gas being sucked away. Under the action of negative pressure, the two telescopic layers 601 contract and squeeze each other to exhaust the gas inside. At this time, the bending body 6021 bends along the radial direction, so that the adaptive tracheal dilator 6 contracts and expands, thereby expanding the trachea. The embedded body 6022 plays a role in shaping the curved body 6021. At the same time, the embedded body 6022 relies on its own elastic force to balance the negative pressure suction force. In this way, the telescopic guide ring 602 can adaptively adjust the curvature according to the size of the negative pressure value, so that the adaptive tracheal dilator 6 can adapt to the trachea of ​​adults and children;

[0034] See also Figure 8The bending body 6021 is an annular porous structure, and the bending body 6021 is made of elastic material (rubber material is preferred, and other materials can also be selected according to actual needs). In order to allow the gas between the two telescopic layers 601 to be sucked away, the bending body 6021 adopts a porous structure to make the internal parts of the adaptive tracheal dilator 6 connected. The elastic force of the bending body 6021 can make the adaptive tracheal dilator 6 quickly restore its shape after the negative pressure disappears, effectively avoiding the adaptive tracheal dilator 6 from scratching the trachea when the suction tube 3 is pulled out.

[0035] The working principle of this solution is as follows: before use, the negative pressure connecting tube 2 is connected to the negative pressure device, and then the medicine dropper 5 and the micro camera 7 are inserted into the sputum suction tube 3, and the medicine dropper 5 is passed out from the medicine dropper port 4. When starting to suction sputum, the sputum suction tube 3 is inserted into the trachea through the mouth or nose, and the negative pressure device is started to start suctioning sputum. Under the suction force of negative pressure, the sputum is sucked into the sputum storage tube 1. Medical staff can understand the situation in the airway with the help of the micro camera 7, avoid damaged parts, and facilitate accurate sputum suction. The negative pressure value is adjusted according to the size of the trachea of ​​adults and children, and the negative pressure value is automatically adjusted according to the size of the negative pressure value. The adaptive tracheal dilator 6 can adaptively expand to expand the trachea, effectively improve the efficiency of sputum suction, and can effectively remove large pieces of sticky sputum. The adaptive tracheal dilator 6 is in a freely stretched state in the initial state, and under the negative pressure suction, the enclosed space surrounded by the two telescopic layers 601 will not become deflated due to the gas being sucked away. Under the action of negative pressure, the two telescopic layers 601 contract and squeeze each other to empty the internal gas. At this time, the bending body 6021 bends along the radial direction, so that the adaptive tracheal dilator 6 can contract and expand, thereby playing a role in expanding the trachea.

[0036] The above description is only the best implementation mode adopted by the present invention in combination with current practical needs, but the protection scope of the present invention is not limited thereto.
