Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a fluid connecting device and a ventilation device. Background Art

[0002] Positive Airway Pressure (PAP) has been used as a means of treating the occurrence of obstructive sleep apnea. The patient is connected to positive pressure air provided by a nasal mask or nasal cannula. The pressure of the air supply source for the patient to breathe is higher than atmospheric pressure. Studies have found that the application of positive airway pressure provides a mechanism that can be described as a "pneumatic splint" to support and stabilize the upper airway, thereby eliminating the occurrence of upper airway obstruction. The application of positive airway pressure can effectively eliminate snoring and obstructive sleep apnea. Current sleep apnea machines can be equipped with heating pipes, which are respectively connected to the air outlet connector of the sleep apnea machine and the breathing mask / nasal plug. The heating pipes can heat the gas inhaled into the user's lungs, on the one hand to avoid condensation of water droplets in the pipe, and on the other hand to prevent the user from inhaling cold gas and causing discomfort.

[0003] Currently, the air outlet connector of a sleep apnea machine is only used to connect the air circuit of the heating pipeline, while the electrical connection of the heating pipeline is generally set at other positions of the ventilator, so that the pipeline connection and the line connection require two actions.

DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0041] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0042] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0043] As can be seen from the background technology, the air outlet connector in the current ventilator is only used to connect the air path of the heating pipeline, and the electrical connector of the heating pipeline is additionally set at other positions of the ventilator. The reason is that the heating circuit of the heating pipeline is difficult to lay out, especially when the air outlet connector needs to be rotated, the heating circuit is prone to problems such as wire entanglement due to rotation.

[0044] The fluid connection device in the embodiment of the present invention includes an air outlet joint and a joint mounting seat that can be docked. The electrical connector is arranged on the air outlet joint, and a winding space is constructed on the air outlet joint. The heating circuit led out from the ventilation equipment can be accommodated in the winding space and connected to the electrical connector. Since the winding space is constructed on the air outlet joint, the problem of difficult layout of the heating circuit of the heating pipeline is well solved, so that the electrical connector can be set on the air outlet joint, and when the air outlet joint is rotated, the heating circuit will no longer have problems such as wire entanglement due to rotation.

[0045] This embodiment provides a fluid connection device that can be used as a docking connection component for a fluid medium transmission pipeline to facilitate the transmission of fluid media (such as from one device or system to another device or system) and enable the utilization of the fluid medium; wherein the fluid medium includes but is not limited to gaseous media such as oxygen and anesthetic mixed gas, and liquid media such as physiological saline and liquid drugs. It can be used in ventilation equipment, and ventilators are only one specific application object of the fluid connection device. It can also be used in other devices or instruments that require the transmission of gaseous or liquid fluid media, such as high-flow oxygen therapy devices.

[0046] refer to Figures 1 to 14 The fluid connection device in this embodiment includes an air outlet connector 100 and a connector mounting seat 200 , and the air outlet connector 100 is docked with the connector mounting seat 200 .

[0047] In this embodiment, the gas outlet connector 100 includes a mounting pipe 112, a docking pipe 111, and a connecting pipe 120. The connecting pipe 120 can be connected to an external heating pipeline.

[0048] In this embodiment, the installation tube 112 , the butt joint tube 111 and the connection tube 120 may be integrally formed.

[0049] The butt joint 111 is nested within the mounting tube 112, and one end of the butt joint 111 is connected to the connecting tube 120, while the other end can be docked with the assembly carrier to transport the fluid medium at the assembly carrier end to the external heating pipeline. The assembly carrier in this embodiment can be formed in an integral manner on the ventilation device (such as a ventilator), or can be assembled and fixed to the ventilation device in a detachable manner, mainly serving as a fixed carrier for the outlet connector 100 or as a pipeline connecting the outlet connector 100 and the air system of the ventilator.

[0050] The cavity between the mounting tube 112 and the docking tube 111 forms the winding space 150, and the outlet connector 100 is provided with an electrical connector. The electrical connector can be understood as a terminal block, and the patient's circuit connection needs to be connected to the heating circuit through this electrical connector. The heating circuit leading from the ventilation device is stored in the winding space 150 and connected to the electrical connector. The heating circuit is laid out within the winding space 150, thereby integrating the heating circuit with the outlet connector 100, making it easier for users to install and use. Especially when the patient's circuit uses an integrated heating circuit, a single action is required to complete the pipe and circuit connection.

[0051] The butt joint pipe 111 and the connecting pipe 120 in this embodiment are connected to form a bend as a whole. It can be understood that the axis of the butt joint pipe 111 and the connecting pipe 120 form an obtuse angle, and the axis angle can be between 110° and 175°. For example, the axis angle of the butt joint pipe 111 and the connecting pipe 120 in this embodiment to form a bend as a whole is 135°.

[0052] The mounting tube 112 forms an arc section 1121 at the connection between the butt tube 111 and the connecting tube 120. The electrical connector is arranged at the outer bend of the arc section of the mounting tube 112, so that sufficient space is reserved as a winding space 150, and the heating circuit led out from the ventilation equipment can be better accommodated in the winding space 150.

[0053] The arcuate end of the mounting tube 112 forms an end surface platform 130, the surface of which is perpendicular to the axial direction of the connecting tube 120. A recess 131 is defined in the end surface platform 130, and the electrical connector is mounted in the recess 131. The electrical connector is mounted in the recess 131, protecting it from bumps and ensuring safety after connection.

[0054] The mounting tube 112 includes a straight section 1121 away from the tube body of the connecting tube 120 and an arc section 1122 extending toward the connecting tube 120. The straight section 1121 and the arc section 1122 are connected. The end of the straight section 1121 is used to form a fixed connection with the assembly carrier, and the end of the arc section 1122 forms the end face platform 130.

[0055] The end surface platform 130 is formed by the end surface platform 130 located at the inner bend of the gas outlet connector 100 and the end surface platform 130 located at the outer bend. The recessed portion 131 is located on the center line of the end surface platform 130 located at the outer bend.

[0056] In this embodiment, the connector mounting base 200 includes: a base body, an air outlet pipe 211 connected to a fluid source, and a wire hole 220 for leading out the heating circuit. The mounting tube 112 forms a rotational connection with the base body within a preset angle. The butt joint 111 is sealed and docked with the air outlet pipe 211, and the wire hole 220 corresponds to the winding space 150 located between the mounting tube 112 and the butt joint 111. The purpose of the sealed docking is electrical isolation. The air outlet pipe 211 and the butt joint 111 are sealed and docked for ventilation. The isolated winding space 150 is used for wiring. Therefore, the winding space 150 does not form an oxygen-rich environment, and the heating circuit does not generate electric sparks, thereby ensuring the safety of the ventilation equipment. In addition, because the wire hole 220 corresponds to the winding space 150 located between the mounting tube 112 and the butt joint 111, the heating circuit has a rotation margin and can be wound along the butt joint 111 to avoid tangling. Therefore, when the air outlet connector 100 is rotated, there will be no tangling or other problems.

[0057] The air outlet pipe 211 in this embodiment is an L-shaped air outlet pipe 211 , and the L-shaped air outlet pipe 211 can be connected to the base 302 in an integrally formed manner.

[0058] In this embodiment, the base is a socket seat 201, which has a socket wall with an elastic snap-fit ​​position 213 near the base. The mounting tube 112 includes a radially outwardly extending snap-fitting convex surface 113. The mounting tube 112 is inserted into the socket seat 201, and the snap-fitting convex surface 113 cooperates with the elastic snap-fitting position 213 to secure the outlet connector 100 to the connector mounting seat 200. The mounting tube 112 can also rotate relative to the socket seat 201.

[0059] The mounting tube 112 is further provided with a limiting convex surface 114 extending radially outward. The limiting convex surface 114 cooperates with the housing 300 of the ventilation device to fix the air outlet connector 100 to prevent the locking convex surface 113 and the elastic locking position 213 from being unlocked when the heating pipeline is plugged in or out.

[0060] In this embodiment, the housing 300 of the ventilation device has a lip 301 that can correspond to the limiting convex surface 114 and is used to limit the limiting convex surface 114 .

[0061] In this embodiment, the joint mounting base 200 further includes a ring body 212 surrounding the air outlet pipe 211 . The ring body 212 is used to install a seal. The seal has a fixing ring sleeved on the ring body 212 and a free end extending toward the inside of the ring body 212 .

[0062] The seal 400 is fixed by the cover 401 (preferably) or by bonding to the ring 212, wherein when the seal 400 is fixed by the cover, it is fixed inside the connector mounting seat 200, and the ring 212 is fixed by a cover screw mounting column 402 provided on the periphery thereof.

[0063] The inner diameter of the butt joint 111 is larger than the outer diameter of the air outlet pipe 211 and smaller than the inner diameter of the ring body 212. When the butt joint is formed, the butt joint 111 is inserted between the ring body 212 and the air outlet pipe 211, and the free end of the seal is tightly against the outer wall of the butt joint 111 to form a seal.

[0064] The mounting tube 112 also includes a raised rib extending radially along the outer wall of the mounting tube 112, and a corresponding limiting rib is provided on the slot wall. The raised rib cooperates with the limiting rib to limit the rotation angle between the mounting tube 112 and the slot seat 201, and can limit the rotation angle between the mounting tube 112 and the slot seat 201 to a preset angle. In this embodiment, the preset angle is within a range of 180° above the horizontal central axis.

[0065] This embodiment also provides a ventilation device, such as a ventilator, high-flow oxygen therapy device, or anesthesia machine that needs to be connected to a fluid source (such as an oxygen cylinder, an oxygen supply center, an anesthesia vaporizer, etc.) before use. The ventilation device includes a gas source input device, a gas pressurizing device, a humidifying device, the above-mentioned fluid connecting device, and a heating pipeline. The gas source input device, the gas pressurizing device, the humidifying device, the fluid connecting device, and the heating pipeline are connected in sequence, wherein the air inlet end of the connector mounting seat 200 can be connected to the humidifying device. When the ventilation device is a high-flow oxygen therapy device, the gas source input device also includes an oxygen input device, and the air outlet connector 100 and the connector mounting seat 200 in the fluid connecting device can be adjusted as needed, that is, the mounting tube 112 and the seat body can form a rotational connection within a preset angle without generating a twisting phenomenon.

[0066] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art can make several simple deductions, modifications or substitutions based on the concept of the present invention.
