Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a ventilator assist device for the care of critically ill patients. Background Technology

[0002] Ventilators for critical care patients are mainly used to assist or replace patients' spontaneous breathing function in order to maintain or improve patients' gas exchange and ventilation functions. In the intensive care unit, ventilators are widely used for respiratory failure caused by various serious illnesses. Ventilator-assisted devices for critical care patients refer to a series of equipment and tools used in conjunction with ventilators in the intensive care unit to better support and manage patients' respiratory function.

[0003] The ventilator includes an oxygen delivery tube for delivering oxygen to the patient. This tube needs to be replaced frequently to ensure its sterility and safety. During use, the oxygen delivery tube connects to the output end of the oxygen delivery tube on the ventilator. When replacing it, the original tube must be removed and replaced with a new one. During this replacement process, airborne bacteria can adhere to the connection between the oxygen delivery tube and the oxygen delivery tube, which is detrimental to maintaining a sterile environment for the tube. Cleaning this connection will affect the ventilator's lifespan. Utility Model Content

[0004] This utility model provides a ventilator-assisted device for the care of critically ill patients to solve the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: it includes an air guide tube with two output ends. The air guide tube consists of an output tube connected to the oxygen output end of a ventilator and two branch tubes whose output ends are connected to an oxygen delivery tube. The output end of the output tube is connected to the input end of the two branch tubes. A valve is provided at the connection between the output tube and the two branch tubes. A connection mechanism for fixing the oxygen delivery tube is provided on the output end of the branch tube, ensuring that the two branch tubes can be used alternately, which is more convenient when used in conjunction with the oxygen delivery tube.

[0006] Furthermore, the connecting mechanism includes a fixed pipe threaded to the output end of the branch pipe and a pushing pipe connected to the outer wall of the fixed pipe. The outer wall of the fixed pipe is provided with a threaded part one, and the inner wall of the pushing pipe is provided with a threaded part two. The threaded part one and the threaded part two are connected, so that the connecting mechanism is movably connected to the output end of the branch pipe, which facilitates disassembly and maintenance.

[0007] Furthermore, the connecting mechanism also includes a connecting pipe connected to the output end of the fixed pipe and a tightening ring plate. The tightening ring plate has a tapered shape, and an annular fixed pipe corridor is formed between the inner wall of the tightening ring plate and the outer wall of the connecting pipe. An annular abutment protrusion is provided on the end of the connecting pipe near the fixed pipe, wherein the fixed corridor protects the connection between the oxygen delivery pipe and the connecting pipe.

[0008] Furthermore, the connecting mechanism also includes an annular groove on one end of the push tube and several extrusion plates connected in the annular groove. Several extrusion channels are provided on the inner side wall of the tightening ring plate. The end of the extrusion plate away from the push tube extends into the solid pipe gallery and is slidably connected to the extrusion channel. By rotating the push tube, the oxygen delivery pipe can be connected and fixed.

[0009] Furthermore, a filter screen is movably connected to the output end of the fixed pipe, thereby reducing the cleaning intensity of the branch pipe and the output pipe.

[0010] Furthermore, a protective cover is movably attached to the end of the connecting pipe away from the fixed pipe to ensure that the branch pipe is not contaminated by the outside when it is not in use.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] This invention features an air delivery tube installed at the output end of the oxygen delivery pipeline of a ventilator. When in use, this air delivery tube directly connects a new oxygen delivery tube to the output end of another cleaned branch tube. At this time, the used branch tube can be cleaned, ensuring that the two branch tubes can be used alternately. This makes the process more convenient, eliminating the need for additional cleaning of the oxygen delivery tube and its connection point each time the tube is changed. It shortens the time required for tube replacement, does not affect the ventilator's operating time, and maintains a sterile and pure environment inside the oxygen delivery tube without compromising its usability.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The following is in conjunction with the appendix Figure 1-6 The technical solutions provided by each embodiment of this utility model are described in detail below.

[0024] This utility model provides a ventilator support device for critically ill patients, including an air delivery tube 1 with two output ends. The air delivery tube 1 consists of an output tube 2 connected to the oxygen output end of the ventilator and two branch tubes 3 whose output ends are connected to the oxygen delivery tube. The output end of the output tube 2 is connected to the input end of the two branch tubes 3. In use, the output tube 2 is first connected to the existing oxygen delivery tube of the ventilator, so that the oxygen output from the ventilator enters the output tube 2. Then, the oxygen enters the two branch tubes 3 connected to the output end of the output tube 2, and is finally delivered by the oxygen delivery tubes 3. The output end is connected to the oxygen supply tube, and one end of the oxygen supply tube is connected to the patient's oxygen mask. Since only one oxygen supply tube is used for oxygen delivery at a time, in order to ensure that oxygen is output from one branch pipe 3 to the oxygen supply tube, a valve 4 is provided at the connection between the output pipe 2 and the two branch pipes 3. The valve 4 is preferably an electromagnetic three-way valve 4, which is intended to facilitate electrical control and operation during use. The valve 4 can control the connection status between the two branch pipes 3 and the output pipe 2. When one branch pipe 3 is in use, the other branch pipe 3 can be cleaned.

[0025] When the oxygen delivery tube needs to be replaced, the new oxygen delivery tube is directly connected to the output end of another cleaned branch tube 3. At this time, the used branch tube 3 can be cleaned, thus ensuring that the two branch tubes 3 can be used alternately. Compared with the implementation method in the prior art, the implementation method in this utility model is more convenient. It does not require additional cleaning of the oxygen delivery tube and the connecting pipe opening each time the oxygen delivery tube is replaced, shortening the time for replacing the oxygen delivery tube. While not affecting the use of the oxygen delivery tube, it ensures a sterile and pure environment inside the fittings used for oxygen delivery. In order to make it easier to connect the oxygen delivery tube to the output end of the branch tube 3, a connecting mechanism 5 for fixing the oxygen delivery tube is provided on the output end of the branch tube 3.

[0026] The connecting mechanism 5 specifically includes a fixed pipe 6 threaded to the output end of the branch pipe 3 and a pushing pipe 7 connected to the outer wall of the fixed pipe 6. The outer wall of the fixed pipe 6 is provided with a first threaded part 601, and the inner wall of the pushing pipe 7 is provided with a second threaded part 701. The first threaded part 601 and the second threaded part 701 are connected. When connecting the connecting mechanism 5 to the branch pipe 3, the fixed pipe 6 is first threaded to the output end of the branch pipe 3, and then the first threaded part 601 on the pushing pipe 7 is aligned with the second threaded part 701 on the fixed pipe 6, thereby threading the pushing pipe 7 onto the fixed pipe 6. This facilitates the disassembly of the entire connecting mechanism 5 and makes subsequent cleaning and maintenance easier.

[0027] In order to fix the oxygen delivery tube to the connecting mechanism 5, the connecting mechanism 5 mentioned above also includes a connecting tube 8 connected to the output end of the fixed tube 6 and a tightening ring plate 9. The tightening ring plate 9 has a tapered shape, and its inner diameter gradually decreases from the direction of the fixed tube 6 to the direction away from the fixed tube 6. An annular tube gallery 10 is formed between the inner side wall of the tightening ring plate 9 and the outer side wall of the connecting tube 8. An annular abutment protrusion 11 is provided on the end of the connecting tube 8 near the fixed tube 6. The connecting mechanism 5 also includes an annular groove 12 opened on one end of the pushing tube 7 and several extrusion plates 13 connected in the annular groove 12. Several extrusion slides 14 are opened on the inner side wall of the tightening ring plate 9. The end of the extrusion plate 13 away from the pushing tube 7 extends into the tube gallery 10 and is slidably connected to the extrusion slide 14.

[0028] In use, one end of the oxygen delivery tube is inserted into the fixed tube gallery 10 until it contacts the abutment protrusion 11. Then, the push tube 7 is rotated. When the push tube 7 is rotated, its threaded part 701 rotates on the threaded part 601. When the push tube 7 pushes the extrusion plate 13 forward, the end of the extrusion plate 13 away from the fixed tube 6 will gradually move down under the guidance of the extrusion slide 14 in the tightening ring plate 9 until the oxygen delivery tube sleeved on the connecting tube 8 is fixed.

[0029] Preferably, in order to reduce the cleaning intensity of the branch pipe 3 and the output pipe 2, a filter screen 15 is movably connected to the output end of the fixed pipe 6. That is, the filter screen 15 is set on the output end of the branch pipe 3. When the fixed pipe 6 is removed, the filter screen 15 can also be removed, which is convenient for disassembly and installation.

[0030] Preferably, in order to ensure that the branch pipe 3 is not contaminated when it is not in use, a protective cover 16 is movably attached to the end of the connecting pipe 8 away from the fixed pipe 6.

[0031] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
