Description

Technical Field

[0001] The utility model relates to a suction tube, in particular to a suction tube with a function of sucking smoke. Background Technique

[0002] During the operation, an electric scalpel is often used to burn and cut the diseased tissue of the patient. At this time, a large amount of smoke will be generated. First, it will affect the line of sight of medical staff. Second, after inhaling a large amount of smoke, it is not conducive to the physical health of medical staff. A suction tube is needed to suck out the smoke.

[0003] For example, a negative pressure surgical suction tube with the publication number of CN205073021U disclosed in the Chinese patent can quickly suck out smoke. Its characteristics are as follows: it includes a cylindrical suction tube body. One end of the suction tube body is a suction port. A flared drainage cover is sleeved on the outer surface of the suction tube body. The drainage cover is an opening with a gradually expanding type with smooth transition and is tightly sleeved on the outer surface of the suction tube body and slides up and down along the suction tube body. The smoke can be sucked when the bell mouth is pulled to the bottommost end.

[0004] When the above-mentioned existing negative pressure surgical suction tube that can quickly suck out smoke is used, some problems are found. First, when using the drainage cover to suck out smoke, the drainage cover will be stuck at the outermost edge of the suction port to prevent the drainage cover from falling off. However, during use, the drainage cover will slide backward, and medical staff need to press it down to hold the drainage cover. Second, when the drainage cover is pulled up to expose the port to suck the liquid, the drainage cover has no limit and will slide down to the end of the suction tube. During use, medical staff need to slowly smooth it to the port of the suction tube, which consumes a lot of precious operation time. Content of the Utility Model

[0005] The purpose of the utility model is to provide a suction tube with a function of sucking smoke and gas to solve the existing problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A suction tube with a function of sucking smoke and gas includes a rigid suction tube. A smoke exhaust cover is slidably sleeved on the rigid suction tube. A flared suction head is fixedly installed at one end of the rigid suction tube. A suction hose is arranged at the other end of the rigid suction tube. A rubber conical limiting block is fixedly installed on the suction hose. A connection through hole is opened on one side of the smoke exhaust cover, and a rubber ring is fixedly installed in the connection through hole.

[0007] Specifically, when the smoke exhaust hood drives the rubber ring to slide onto the horn-shaped suction head, the rubber ring will be stuck on the horn-shaped suction head. Apply a certain downward pressure to deform the rubber ring. Thus, due to friction, the smoke exhaust hood will be stuck on the horn-shaped suction head. Move the rigid suction tube to drive the horn-shaped suction head to move. The movement of the horn-shaped suction head can drive the smoke exhaust hood to move. There is no need for manual operation to keep the smoke exhaust hood at the end of the horn-shaped suction head. The rubber conical limit block will limit the further backward movement of the smoke exhaust hood. Thus, the smoke exhaust hood can only slide on the rigid suction tube and the suction hose between the rubber conical limit block and the horn-shaped suction head.

[0008] Preferably, a connector is fixedly installed at the other end of the rigid suction tube.

[0009] Specifically, the suction hose is connected through the connector.

[0010] Preferably, the outer diameter of the connector is slightly larger than the inner diameter of the connector.

[0011] Specifically, by making the outer diameter of the connector slightly larger than the inner wall of the connector, the suction hose can be sleeved on the connector to connect the rigid suction tube and the suction hose together.

[0012] Preferably, the horn-shaped suction head is integrally in the shape of a horn, and the outer diameter of the port is slightly larger than the outer diameter of the end.

[0013] Specifically, by designing the horn-shaped suction head to gradually expand towards the port, the outer diameter of the port is slightly larger than the outer diameter of the end. Thus, the rubber ring can move at the end of the horn-shaped suction head. During the gradual outward movement, it will be stuck at the middle position of the horn-shaped suction head. Thus, the smoke exhaust hood is fixed on the horn-shaped suction head.

[0014] Preferably, the outer diameter of the port of the horn-shaped suction head is larger than the inner diameter of the rubber ring.

[0015] Specifically, by the outer diameter of the port of the horn-shaped suction head being larger than the inner diameter of the rubber ring, it is avoided that the smoke exhaust hood slips off from the horn-shaped suction head.

[0016] Preferably, the maximum outer diameter of the rubber conical limit block is larger than the inner diameter of the rubber ring.

[0017] Specifically, by the maximum outer diameter of the rubber conical limit block being larger than the inner diameter of the rubber ring, it is avoided that the smoke exhaust hood slides towards the end through the rubber conical limit block.

[0018] Preferably, both the rigid suction tube and the horn-shaped suction head are made of rigid materials.

[0019] Specifically, by making the rigid suction tube and the horn-shaped suction head of rigid materials, it is convenient to grasp and adjust the position.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] 1. By designing the horn-shaped suction head as a horn shape and making the inner diameter of the rubber ring smaller than the maximum outer diameter of the horn-shaped suction head, when the smoke exhaust hood drives the rubber ring to slide onto the horn-shaped suction head, the rubber ring will get stuck on the horn-shaped suction head. Applying a certain downward pressure causes the rubber ring to deform, and thus due to friction, the smoke exhaust hood will be stuck on the horn-shaped suction head. Compared with the existing device, there is no need for manual operation to keep the smoke exhaust hood at the end of the horn-shaped suction head.

[0022] 2. By sliding the smoke exhaust hood backward, making the smoke exhaust hood get stuck on the rubber conical limit block, applying a certain downward pressure causes the rubber ring to deform, and thus due to friction, the smoke exhaust hood will be stuck on the rubber conical limit block, thereby fixing the smoke exhaust hood on the suction hose. This avoids the problem that during the operation, the movement of the suction hose drives the smoke exhaust hood to shake randomly, and at the same time avoids the situation where the smoke exhaust hood falls to the end of the suction hose and requires manual operation to slowly move the smoke exhaust hood to the front end.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Please refer to Figures 1-4, the present utility model provides a technical solution: a suction tube with a smoking gas function, which includes a rigid suction tube 1. A smoke exhaust hood 3 is slidably sleeved on the rigid suction tube 1. One end of the rigid suction tube 1 is fixedly installed with a horn-shaped suction head 101. At the other end of the rigid suction tube 1, a suction hose 2 is provided. A rubber conical limit block 201 is fixedly installed on the suction hose 2. A connection through hole 301 is opened on one side of the smoke exhaust hood 3, and a rubber ring 302 is fixedly installed in the connection through hole 301.

[0030] In this implementation scheme, by designing the horn-shaped suction head 101 to be horn-shaped, and the inner diameter of the rubber ring 302 is smaller than the maximum outer diameter of the horn-shaped suction head 101. When the smoke exhaust hood 3 drives the rubber ring 302 to slide onto the horn-shaped suction head 101, the rubber ring 302 will be stuck on the horn-shaped suction head 101. Applying a certain downward pressure causes the rubber ring 302 to deform. Thus, due to the frictional force, the smoke exhaust hood 3 will be stuck on the horn-shaped suction head 101. Moving the rigid suction tube 1 drives the horn-shaped suction head 101 to move. The movement of the horn-shaped suction head 101 can drive the smoke exhaust hood 3 to move. There is no need for manual operation to keep the smoke exhaust hood 3 at the end of the horn-shaped suction head 101. The rubber conical limit block 201 will limit the further backward movement of the smoke exhaust hood 3. As a result, the smoke exhaust hood 3 can only slide on the rigid suction tube 1 and the suction hose 2 between the rubber conical limit block 201 and the horn-shaped suction head 101, effectively avoiding the problem that the smoke exhaust hood 3 slides down to the end of the suction hose 2 and requires manual operation to slowly move the smoke exhaust hood 3 to the front end during use.

[0031] Among them, in order to achieve the purpose of connecting the rigid suction tube 1 and the suction hose 2, the following technical solution is adopted in this device: A connection head 102 is fixedly installed at the other end of the rigid suction tube 1, and the outer diameter of the connection head 102 is slightly larger than its inner diameter.

[0032] Since the whole suction hose 2 is a common medical hose, which is used to connect the negative pressure pump and the rigid suction tube 1, and the outer diameter of the connection head 102 is slightly larger than the inner wall of the connection head 102, the suction hose 2 can be sleeved on the connection head 102 to connect the rigid suction tube 1 and the suction hose 2 together.

[0033] Among them, in order to achieve the purpose of clamping the smoke exhaust hood 3, the following technical solution is adopted in this device: The horn-shaped suction head 101 is overall in a horn shape, and the outer diameter of the port is slightly larger than the outer diameter of the end.

[0034] By designing the horn-shaped suction head 101 to gradually expand towards the port, the outer diameter of the port is slightly larger than the outer diameter of the end. Thus, the rubber ring 302 can move at the end of the horn-shaped suction head 101. During the gradual outward movement, it will be stuck at the middle position of the horn-shaped suction head 101, thereby fixing the smoke exhaust hood 3 on the horn-shaped suction head 101.

[0035] Among them, in order to achieve the purpose of fixing the exhaust hood 3 to the suction hose 2, the present device is realized by the following technical solutions: the outer diameter of the port of the horn-shaped suction head 101 is greater than the inner diameter of the rubber ring 302, the maximum outer diameter of the rubber conical limit block 201 is greater than the inner diameter of the rubber ring 302, and both the rigid suction pipe 1 and the horn-shaped suction head 101 are made of rigid materials.

[0036] Since the outer diameter of the port of the horn-shaped suction head 101 is greater than the inner diameter of the rubber ring 302, it is avoided that the exhaust hood 3 slides off from the horn-shaped suction head 101. The maximum outer diameter of the rubber conical limit block 201 is greater than the inner diameter of the rubber ring 302, which prevents the exhaust hood 3 from sliding towards the end through the rubber conical limit block 201. At the same time, the rubber ring 302 can be stuck on the rubber conical limit block 201 to fix the exhaust hood 3 on the suction hose 2, avoiding the exhaust hood 3 from constantly shaking as the suction hose 2 moves, which interferes with the operation of medical staff. The rigid suction pipe 1 and the horn-shaped suction head 101 are made of rigid materials, which is convenient for grasping and adjusting the position.

[0037] The working principle and usage process of the present utility model: When in use, the end of the suction hose 2 needs to be connected to a negative pressure pump. Slide the exhaust hood 3 onto the horn-shaped suction head 101, and the rubber ring 302 will be stuck on the horn-shaped suction head 101. Apply a certain downward pressure to deform the rubber ring 302, so that due to friction, the exhaust hood 3 will be stuck on the horn-shaped suction head 101. At this time, moving the rigid suction pipe 1 through the horn-shaped suction head 101 can drive the exhaust hood 3 to move, thereby sucking the smoke generated during the operation. Slide the exhaust hood 3 backward so that the exhaust hood 3 is stuck on the rubber conical limit block 201. Apply a certain downward pressure to deform the rubber ring 302, so that due to friction, the exhaust hood 3 will be stuck on the rubber conical limit block 201, thereby fixing the exhaust hood 3 on the suction hose 2 and preventing the exhaust hood 3 from shaking randomly as the suction hose 2 moves during the operation.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
