Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, in particular to a breathing machine pipeline anti -drop device. BACKGROUND

[0002] In medical breathing auxiliary equipment, the use of breathing machine is very important, can be used for treating respiratory failure patients, provides positive pressure ventilation for them to help complete gas exchange. For patients with respiratory depression caused by nervous system diseases, can replace autonomous breathing to avoid complications such as brain damage. After cardiopulmonary resuscitation, it can help maintain respiratory function and promote heart and lung function recovery. However, the existing breathing machine pipeline anti-drop device still has some problems, for example, the patent with the announcement number CN219110532U discloses a breathing machine connecting pipe connecting mechanism that prevents falling off, on the one hand, the spring in the device is the key component for realizing the automatic clamping of the clamping head. But due to the spring, after long-term use or frequent operation, it is most likely that the elasticity will weaken, fatigue or even break. Once the spring fails, the clamping head may not be able to normally clamp into the clamping groove, resulting in the loss of the anti-falling function of the connecting mechanism. In addition, the edges of the clamping head and the clamping groove may be worn during frequent plugging and unplugging, affecting the tightness of the clamping and the use of the breathing machine. On the other hand, the connecting structure of the device is relatively complex, it needs to pull the sliding sleeve, use the spring force to make the clamping head pass through the perforation and clamp with the clamping groove, and also includes multiple steps such as pre-clamping of the clamping ring and the inner wall to realize the connection and anti-falling function. In actual clinical operation, especially in emergency situations, the operator needs to be skilled and quick and accurate, and every second is crucial in emergency scenes such as rescuing patients, and complex or unskilled operation is easy to affect the timely use of the breathing machine, thereby affecting the treatment. CONTENT OF THE UTILITY MODEL

[0003] (I) The technical problem solved

[0004] In view of the limitations of the existing breathing machine pipeline anti-falling device, the utility model aims at providing a breathing machine pipeline anti-falling device, through the magnetic connection of the breathing pipe, the connecting pipe and the socket pipe, plus the clamping of the rotating socket pipe rear block and the clamping groove, multiple connection modes are formed, even if one of the connection modes is disturbed by external force, another connection mode can guarantee the connection stability of the pipeline, greatly reducing the risk of pipeline falling off. The use of the safety clamp further enhances the fastening force of the connection, making the connection between the pipelines more secure. Especially for those who may be subjected to greater external force, such as patients who are restless in the hospital bed or need to move their bodies simply, the safety clamp can prevent the pipeline from falling off accidentally. Moreover, medical staff only need to perform basic operations such as insertion, rotation and clamping of the safety clamp, without complex multi-component cooperative operation, reducing the requirement for operation proficiency, even in emergency situations, the pipeline connection and fixation can be completed relatively quickly, ensuring the timely use of the breathing machine and the treatment of the patient.

[0006] To achieve the above object, the utility model provides the following technical scheme: a breathing machine pipeline anti-falling device, including breathing pipe, connecting pipe and socket pipe connecting breathing pipe and connecting pipe, socket pipe is divided into breathing section and connecting section, breathing section and connecting section are fixedly connected with connecting platform in the middle, the both sides of connecting platform are provided with inner annular magnet respectively, wherein, the side close to breathing pipe is breathing pipe inner annular magnet, the side close to connecting pipe is connecting pipe inner annonal magnet, the side close to socket pipe of breathing pipe is provided with breathing pipe outer annular magnet, the side close to socket pipe of connecting pipe is provided with connecting pipe outer annular magnet. Breathing pipe and connecting pipe are connected through socket pipe, here, the breathing pipe is the pipe connecting breathing machine, and the connecting pipe is the pipe connecting patient, and the socket pipe connects the breathing pipe and the connecting pipe together, avoids the falling off of the breathing pipe and the connecting pipe, and influences the use of breathing machine, specifically, the breathing pipe outer annular magnet on the breathing pipe corresponds with the breathing pipe inner annular magnet on the connecting platform, and the connecting pipe outer annular magnet on the connecting pipe corresponds with the connecting pipe inner annular magnet on the connecting platform, that is to say, the breathing pipe and the connecting pipe are magnetically connected with the socket pipe, since the inner annular magnet is arranged on the connecting platform, and the outer annular magnet on the breathing pipe and the connecting pipe is magnetically connected with the inner annular magnet, therefore, the breathing pipe and the connecting pipe are inserted into the socket pipe and connected with the connecting platform closely, and the socket pipe is communicated in the middle.

[0007] Preferably, the breathing section and the connecting section are both double-layered, divided into an inner layer and an outer layer, the distance between the inner layer and the outer layer is the width of the connecting platform, and the breathing tube and the connecting tube are respectively arranged in the middle of the inner layer and the outer layer. In order to facilitate the magnetic connection of the breathing tube, the connecting tube and the sleeve pipe, and at the same time prevent them from falling off, the sleeve pipe is provided with double layers, the inner layer and the outer layer sandwich the breathing tube and the connecting tube, and the width of the connecting platform is reserved in the middle, that is, the position of the close connection of the breathing tube, the connecting tube and the sleeve pipe is reserved, which can be understood as that a circular ring is formed between the inner layer and the outer layer, and the breathing tube and the connecting tube are closely connected with the inner annular magnet on the connecting platform after entering the circular ring. Specifically, taking the breathing tube as an example, that is, the outer wall of the inner layer of the sleeve pipe is closely combined with the inner wall of the breathing tube, and the outer wall of the breathing tube is closely combined with the inner wall of the outer layer, and the connecting tube is the same.

[0008] It should be noted that the outer wall surface of the inner layer and the inner wall surface of the outer layer, that is, the contact area with the breathing tube and the connecting tube, is provided with anti-skid lines.

[0009] Preferably, the outer layer of the breathing section is annularly provided with a plurality of first annular clamping grooves on the inner wall of the side close to the connecting platform, and the outer layer of the connecting section is annularly provided with a plurality of second annular clamping grooves on the inner wall of the side close to the connecting platform. A plurality of first annular clamping blocks are annularly fixed on the outer wall of the side close to the sleeve pipe of the breathing tube, and a plurality of second annular clamping blocks are annularly fixed on the outer wall of the side close to the sleeve pipe of the connecting tube, the plurality of first annular clamping blocks correspond to the first annular clamping grooves one by one, and the plurality of second annular clamping blocks correspond to the second annular clamping grooves one by one. The first annular clamping blocks on the breathing tube correspond to the first annular clamping grooves of the outer layer of the breathing section of the sleeve pipe one by one, that is, the first annular clamping blocks can be clamped into the first annular clamping grooves, and the second annular clamping blocks can also be clamped into the second annular clamping grooves, which is equivalent to a locking mechanism, which is provided with a ring, so that the connection of the breathing tube, the connecting tube and the sleeve pipe is more close. More specifically, when the breathing tube enters between the outer layer and the inner layer and is close to the connecting platform, a plurality of first annular clamping blocks on the breathing tube will be in contact with the first annular clamping grooves, then the first annular clamping blocks will be clamped into the first annular clamping grooves and clamped by rotating the breathing tube or the sleeve pipe, and the connection of the second annular clamping blocks on the connecting tube and the second annular clamping grooves is the same. Whether the clamping is connected can be determined by pulling the breathing tube and the connecting tube outward to check whether they will move, the specific arrangement and connection mode of the annular clamping blocks and the annular clamping grooves are adopted by conventional technology, so they are not described in detail.

[0010] Preferably, the breathing section is fixedly connected with a first safety clip on the side away from the connecting platform, and the connecting section is fixedly connected with a second safety clip on the side away from the connecting platform. A part of the first safety clip is fixedly connected with the breathing section, and the other part contacts the breathing tube, which is equivalent to clamping the sleeve connecting pipe and the breathing tube together. The second safety clip clamps the sleeve connecting pipe and the connecting pipe together. The first safety clip is internally provided with a spiral pattern corresponding to the outer wall of the breathing tube, and the second safety clip is internally provided with a spiral pattern corresponding to the outer wall of the connecting pipe. The specific structural design and connection mode of the first safety clip and the second safety clip adopt conventional technology, and therefore will not be described in detail.

[0011] Preferably, the diameter of the breathing section is greater than the diameter of the connecting section. This is because the diameter of the breathing tube itself is greater than the diameter of the connecting pipe. Therefore, the diameter of the breathing section connected with the breathing tube is slightly greater than the diameter of the breathing tube, and the diameter of the connecting section connected with the connecting pipe is slightly greater than the diameter of the connecting pipe. In this way, when connected, the breathing tube can be smoothly inserted into the breathing section, and due to the small difference in diameter, after insertion, the breathing tube can be in close contact with the inner wall of the breathing section through the moderate interference fit therebetween, effectively preventing gas leakage and loosening, falling off and other adverse phenomena when subjected to external force pulling or shaking. Similarly, the diameter of the connecting section is slightly greater than the diameter of the connecting pipe, and when the connecting pipe is inserted into the connecting section, it can be tightly fitted to the inner wall of the connecting section. This tight fit not only ensures the sealing of the gas in the pipeline transmission process, but also enhances the stability of the entire connecting structure. Even under the action of external force that may be generated by the patient turning over or moving, the reliable connection between the breathing tube, the connecting pipe and the sleeve connecting pipe can still be maintained, thereby providing a strong guarantee for the normal operation of the breathing machine and the safe use of the patient.

[0012] (Three) beneficial effects

[0013] (1) By arranging the inner annular magnet of the breathing tube, the outer annular magnet of the breathing tube, the inner annular magnet of the connecting pipe and the outer annular magnet of the connecting pipe, when the breathing tube and the connecting pipe are connected with the sleeve connecting pipe, the attractive force between the magnets can prevent the pipes from falling off due to external force pulling, twisting and other conditions during use from multiple angles. This magnetic connection provides an additional fixing force, enhancing the stability of the entire pipeline connection. In addition, the clamping of the first safety clip and the second safety clip provides an additional fixing force for the pipeline connection. Combined with the magnet adsorption and the cooperation of the annular clamping block and the clamping groove, a multiple protection mechanism is formed, greatly reducing the risk of the pipeline falling off during use.

[0014] (2) The first annular clamping block on the breathing tube and the first annular clamping groove on the outer layer of the breathing section, and the second annular clamping block on the connecting tube and the second annular clamping groove on the outer layer of the connecting section correspond one by one. This makes the breathing tube and the connecting tube after being inserted into the sleeve pipe, can be further fixed in position through the cooperation of the annular clamping block and the clamping groove, limit the displacement of the pipeline in the axial and radial direction, effectively prevent the loosening and falling of the pipeline, provide double protection for the safety of the patient during using the breathing machine.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described below with reference to the accompanying drawings in the embodiments of the utility model. Figure 1 - the accompanying drawings Figure 6 The technical solutions in the embodiments of the utility model will be described below with reference to the accompanying drawings in the embodiments of the utility model.

[0023] Embodiment one: as Figure 1The utility model discloses a first specific embodiment provides a breathing machine pipeline anti -drop device, including breathing pipe 1, connecting pipe 2 and the sleeve pipe 3 of connecting breathing pipe 1 and connecting pipe 2, sleeve pipe 3 is divided into breathing section 31 and connecting section 32, and the middle fixed connection of breathing section 31 and connecting section 32 has connecting platform 33, and the both sides of connecting platform 33 are provided with inner annular magnet 4 respectively, wherein, the side of breathing pipe 1 is breathing pipe inner annular magnet 41, and the side of connecting pipe 2 is connecting pipe inner annular magnet 42, and the side top of breathing pipe 1 near sleeve pipe 3 is provided with breathing pipe outer annular magnet 11, and the side top of connecting pipe 2 near sleeve pipe 3 is provided with connecting pipe outer annular magnet 21. Breathing pipe 1 and connecting pipe 2 and sleeve pipe 3 form magnetic connection. This magnetic connection provides adsorption in multiple directions, can effectively resist the tensile force, torque and other external force effect that pipeline is subjected to in the use process, and the attraction between magnet can prevent the pipeline from easily falling off sleeve pipe 3, ensure the stability of breathing machine pipeline connection. Inner annular magnet 4 is distributed on the both sides of connecting platform 33, and cooperates with outer annular magnet, functions from the interface of pipeline connection and the position close to the interface simultaneously, make breathing pipe 1 and connecting pipe 2 can be more firmly connected with sleeve pipe 3, and simultaneously, only need to make breathing pipe 1 and connecting pipe 2 close to sleeve pipe 3 when installing, and magnet will automatically adsorb and preliminarily fix the position of pipeline. Medical staff does not need to carry out complicated screwing, clamping and other operations, saves installation time, especially in the emergency medical situation, quickly and accurately connect pipeline is very important.

[0024] Breathing section 31 and connecting section 32 are both double-layered, divided into inner layer 34 and outer layer 35, and the distance between the inner layer 34 and the outer layer 35 is the width of the connecting platform 33, and the breathing pipe 1 and the connecting pipe 2 are respectively arranged in the middle of the inner layer 34 and the outer layer 35. The double-layered setting of the breathing section 31 and the connecting section 32 can effectively isolate and protect the breathing pipe 1 and the connecting pipe 2, and can avoid the mutual friction and extrusion of the two pipes, thereby reducing the wear of the pipes. In addition, the distance between the inner layer 34 and the outer layer 35 is the width of the connecting platform 33, which ensures that the breathing pipe 1 and the connecting pipe 2 can be accurately positioned when connected to the connecting platform 33, facilitating smooth magnetic connection and clamping.

[0025] The outer layer 35 of the breathing section 31 is annularly provided with a plurality of first annular clamping grooves 310 on the inner wall of the side close to the connecting platform 33, and the outer layer 35 of the connecting section 32 is annularly provided with a plurality of second annular clamping grooves 320 on the inner wall of the side close to the connecting platform 33. The first annular clamping grooves 310 and the second annular clamping grooves 320 can be used to further fix the breathing tube 1 and the connecting tube 2. When the breathing tube 1 and the connecting tube 2 are respectively installed between the inner and outer layers of the breathing section 31 and the connecting section 32, the annular clamping grooves can clamp the pipes to prevent the pipes from moving in the axial direction, so that the pipes can be more stably placed in the specified position, avoiding loosening of the pipes due to accidental pulling or vibration of the equipment. In addition, the design of the annular clamping grooves can work with other components such as magnetic connection, safety clamp, etc. That is, the magnetic connection mainly provides the adsorption force between the pipes, the safety clamp provides additional clamping force, and the annular clamping groove limits the displacement of the pipes from another angle. The combination of multiple connection methods forms a more stable connection system, further reducing the risk of pipe falling off.

[0026] The breathing tube 1 is annularly fixed with a plurality of first annular clamping blocks 12 on the outer wall of the side close to the sleeve pipe 3, and the connecting tube 2 is annularly fixed with a plurality of second annular clamping blocks 22 on the outer wall of the side close to the sleeve pipe 3. The plurality of first annular clamping blocks 12 correspond to the first annular clamping grooves 310 one by one, and the plurality of second annular clamping blocks 22 correspond to the second annular clamping grooves 320 one by one. The design of one-to-one correspondence between the annular clamping blocks and the annular clamping grooves can realize the precise butt joint between the breathing tube 1, the connecting tube 2 and the sleeve pipe 3. When the clamping blocks are embedded in the clamping grooves, the rotation of the pipes can be effectively limited in the circumferential direction, so that the breathing tube 1 and the connecting tube 2 can be stably fixed in the sleeve pipe 3, preventing them from rotating, thereby ensuring the stability of the pipe connection. Moreover, the cooperation of the clamping blocks and the clamping grooves greatly enhances the anti-falling ability of the pipes. They constrain the pipes in the axial and circumferential directions, forming a stable connection structure that can withstand greater tension and reduce the possibility of accidental pipe falling. When installing the breathing tube 1 and the connecting tube 2, the corresponding relationship between the clamping blocks and the clamping grooves can help medical staff quickly and accurately install the pipes into the sleeve pipe 3. Medical staff only need to align the clamping blocks with the clamping grooves and then gently push them in to complete the installation of the pipes. This clear installation method can improve work efficiency, especially in the case of emergency rescue and other situations that require quick connection of pipes.

[0027] The first safety clip 5 is fixedly connected to the side of the breathing section 31 away from the connecting platform 33, and the second safety clip 6 is fixedly connected to the side of the connecting section 32 away from the connecting platform 33. After the breathing tube 1 and the connecting tube 2 are connected to the sleeve pipe 3 through magnetic connection, block and slot connection, or other methods, the safety clips further reinforce the connection. Then when the patient is in a state of unconsciousness and moves violently, or the device is accidentally bumped or shaken, these situations may generate a large pulling force or impact force on the pipe connection. The safety clips can effectively prevent the pipe from falling off due to these external forces, thereby ensuring the continuity of the patient's breathing. In addition, during normal use of the device, even without a large external force, the pipe may also produce slight shaking due to air flow, gravity, and other factors. The first safety clip 5 and the second safety clip 6 can limit this shaking, so that the pipe remains in a relatively stable state, thereby reducing the risk of connection loosening due to shaking, and also improving the comfort of the patient's use.

[0028] The diameter of the breathing section 31 is larger than the diameter of the connecting section 32. This difference in diameter helps to optimize the internal structure of the sleeve pipe 3, providing a more reasonable spatial layout for the connection of the breathing tube 1 and the connecting tube 2. The larger breathing section 31 can provide sufficient accommodation space for the breathing tube 1, avoiding excessive compression or deformation of the breathing tube 1 in the sleeve pipe 3, thereby ensuring the normal function of the breathing tube 1. At the same time, the smaller connecting section 32 can more closely fit the connecting tube 2, enhancing the stability of the connection. That is, when using magnetic connection or clamping, etc., this different diameter design can make the connection components more effectively function at the appropriate pipe diameter position. And during gas delivery, the larger diameter of the breathing section 31 can reduce the flow rate of gas in the breathing tube 1, reducing the resistance of gas flow, and the larger pipe diameter provides a more spacious passage for gas, making the patient's breathing more smooth. The relatively smaller diameter of the connecting section 32 when connected to other devices can be adjusted according to the requirements of the device and the gas flow demand, achieving reasonable gas distribution and delivery in the entire pipe system, which helps to improve the safety and effectiveness of respiratory therapy.

[0029] Working principle: First, insert the breathing tube 1 into the breathing section 31 of the sleeve pipe 3, because the breathing section 31 is a double-layer structure, the breathing tube 1 will enter the space between the inner layer 34 and the outer layer 35, at the same time, insert the connecting tube 2 into the connecting section 32 of the sleeve pipe 3, which is also located between the inner layer 34 and the outer layer 35 of the connecting section 32. When the pipeline is inserted into the appropriate position, slightly rotate the sleeve pipe 3, the first annular clamping block 12 will be embedded in the first annular clamping groove 310, and the second annular clamping block 22 will be embedded in the second annular clamping groove 320. The matching structure of the clamping groove and the clamping block restricts the axial and radial movement of the breathing tube 1 and the connecting tube 2 in the sleeve pipe 3, so that the pipeline is preliminarily fixed in the sleeve pipe 3, and the stability of the pipeline connection is preliminarily ensured. At the same time, the breathing tube outer annular magnet 11 near the top end of the breathing tube 1 on one side of the sleeve pipe 3 is attracted to the breathing tube inner annular magnet 41 on one side of the connecting platform 33 of the breathing section 31 of the sleeve pipe 3, and the connecting tube outer annular magnet 21 near the top end of the connecting tube 2 on one side of the sleeve pipe 3 is attracted to the connecting tube inner annular magnet 42 on one side of the connecting platform 33 of the connecting section 32 of the sleeve pipe 3, preventing the pipeline from falling off from multiple directions; Finally, a part of the first safety clamp 5 is fixedly connected with the breathing section 31, and the other part contacts the breathing tube 1, tightly clamping the breathing section 31 of the sleeve pipe 3 and the breathing tube 1 together, similarly, the second safety clamp 6 clamps the connecting section 32 of the sleeve pipe 3 and the connecting tube 2 together, at this time, the breathing machine can work, and the gas is transmitted from the breathing tube 1 to the connecting tube 2 through the sleeve pipe 3.

[0030] Example two: when encountering an emergency situation that requires rapid disassembly of the pipeline, such as an emergency replacement of the breathing equipment due to a sudden condition of the patient. First, loosen the first safety clamp 5 and the second safety clamp 6 respectively, then rotate the sleeve pipe 3 in the opposite direction, so that the first annular clamping block 12 is separated from the first annular clamping groove 310, and the second annular clamping block 22 is separated from the second annular clamping groove 320, the breathing tube 1 is pulled out from the breathing section 31, and the connecting tube 2 is pulled out from the connecting section 32, thereby quickly realizing the separation of the pipeline, so as to carry out subsequent emergency operation.
