Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, specifically an anti-collision buffer protection structure for an oxygen flow meter glass. Background Technology

[0002] The buoy-type oxygen inhaler, a key medical device that relies on the buoy principle to precisely regulate oxygen flow and provide patients with a continuous and constant oxygen supply, is explicitly classified as a Class II medical device. With its reliable performance and stable oxygen supply capability, it is widely used in numerous scenarios such as hospital emergency rooms, wards, research institutions, and factories and mines, playing an irreplaceable and vital role in emergency oxygen supply and hypoxia treatment, and is one of the important tools for safeguarding patients' lives and health.

[0003] In the buoy-type oxygen inhaler, the glass tube is a key component—the buoy flow meter. However, existing buoy flow meter glass tubes have significant shortcomings. In practical applications, whether during transport or daily use, the glass tube is highly susceptible to impact or drop due to limited operating space for medical staff, frequent equipment handling, or unintentional touches by patients. Upon such impact, the glass tube can shatter instantly due to direct force. This not only interrupts oxygen supply and affects the patient's treatment but also may cause secondary injuries to medical staff and patients due to flying glass shards.

[0004] What's even more challenging is that, due to the inherent properties of glass, broken glass tubes are difficult to repair and must be replaced entirely. Furthermore, glass tube breakage is quite common, requiring frequent replacements. This not only increases the workload and time costs of equipment maintenance but also leads to a significant increase in operating costs, placing a substantial financial burden on medical institutions.

[0005] Existing technologies have also developed methods to prevent breakage by improving the material, such as changing it to plastic or silicone. However, if high-precision readings, high temperature and high pressure resistance, or long-term monitoring are required, glass must still be used. Compared to glass, silicone and plastic have lower transparency, which may affect the observation of the float's position. Since changing the material of the glass tube is not actually used, this application, based on the problems encountered in the work and after counter-testing, has developed a glass anti-collision buffer protective sleeve for a float-type flowmeter and its installation structure. Utility Model Content

[0006] The purpose of this invention is to overcome the defects and shortcomings of the existing technology and provide an anti-collision buffer protection structure for oxygen flow meters, thus solving various problems existing in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An oxygen flow meter glass anti-collision buffer protection structure includes a protective sleeve, the bottom end of which is fitted and fixed on the base of the float-type flow meter. The side of the protective sleeve has an observation window corresponding to the distribution position of the scale lines on the flow meter glass tube. An elastic shock-absorbing sleeve is fitted outside the protective sleeve. The inner wall of the protective sleeve has a groove formed by multiple spaced-apart blocks arranged radially, and a buffer block is fitted in the groove.

[0009] The protective sleeve is made of plastic, and its bottom end is fixed to the base of the float flow meter by a snap-fit ​​sleeve. The snap-fit ​​sleeve includes upper and lower connecting pipes, and the connecting pipes have spaced tightening holes arranged radially upward around their circumference. A knob screw is installed in the tightening hole.

[0010] The outer circumferential surface of the upper connecting pipe is provided with a groove corresponding to the position of the scale line of the flow meter glass tube.

[0011] The observation window is a vertically oriented strip-shaped opening.

[0012] The strip-shaped opening has graduation lines distributed on one side, and the graduation lines correspond to the distribution positions of the graduation lines on the flow meter glass tube.

[0013] The elastic shock-absorbing sleeve includes a sleeve body made of rubber material, and an opening corresponding to the observation opening is provided on one side of the sleeve body.

[0014] The outer surface of the sleeve has multiple outwardly protruding rubber ribs, and the rubber ribs are integrally formed with the sleeve.

[0015] The depth of the slot is less than the distance between the inner wall of the protective sleeve and the outer wall of the flow meter glass tube.

[0016] The buffer block is a foam block or a rubber block, and both the inner and outer sides of the buffer block are arc-shaped surfaces that are in close contact with the outer wall of the flow meter glass and the inner wall of the protective sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The present invention has a reasonable structural design, which significantly improves the protection effect on the glass tube. An observation window opening is opened on the protective sleeve at the position corresponding to the scale line, so as to achieve the effect of direct observation and comprehensive protection.

[0019] 2. This application adds an elastic shock-absorbing sleeve to the outside of the protective sleeve, which can further enhance the shock absorption effect. When subjected to external impact, the rubber ribs will deform, absorb and disperse the impact energy, reduce the vibration transmitted to the protective sleeve and glass tube, and thus reduce the risk of the glass tube breaking due to vibration.

[0020] 3. The protective sleeve is fixed to the base, allowing medical staff to quickly and easily remove and install the protective sleeve, which facilitates regular and thorough cleaning of the glass tube;

[0021] In summary, this application utilizes a multi-layered structure with a combination of soft and hard materials. The outer layer is an elastic buffer layer, the middle layer is made of plastic, which is lightweight and low-cost, and the inner layer is also an elastic buffer layer. This creates a structure that can simultaneously resist initial impacts and absorb residual energy, thereby reducing the vibration transmitted to the flow meter and greatly improving the stability and safety of the glass tube.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] See appendix Figure 1-5 ;

[0031] An anti-collision buffer protection structure for an oxygen flow meter glass is characterized by: a protective sleeve 1, the bottom end of which is fitted and fixed to the base of a float-type flow meter 2; an observation window 3 on the side of the protective sleeve 1 corresponding to the distribution of the scale lines on the flow meter glass tube; an elastic shock-absorbing sleeve 4 fitted outside the protective sleeve 1; and a groove formed by multiple spaced-apart blocks 5 arranged radially on the inner circumference of the protective sleeve 1, in which buffer blocks 6 are fitted. No buffer blocks 6 are present at the position of the observation window. Through a multi-layered structure combining soft and hard materials, with an outer elastic buffer layer, a middle layer of lightweight and low-cost plastic material, and an inner elastic buffer layer, a structure is formed that can simultaneously resist initial impacts and absorb residual energy, thereby reducing the vibration transmitted to the flow meter.

[0032] Furthermore, the protective sleeve 1 is made of plastic, and its bottom end is fixed to the base of the float-type flowmeter by a snap-fit ​​sleeve 7. The snap-fit ​​sleeve 7 includes upper and lower connecting tubes, with spaced tightening holes 8 distributed radially upwards around the circumference of the connecting tubes, and a knob screw 9 installed in the tightening hole 8. The outer circumference of the upper connecting tube has a groove 10 corresponding to the position of the scale line on the flowmeter glass tube. The groove design avoids obstructing the bottom of the scale line position on the flowmeter glass tube, and while providing a secure connection, it also facilitates complete observation of the scale line. The protective sleeve can completely wrap the glass tube, providing it with all-round physical protection, effectively preventing the glass tube from breaking due to external forces such as collisions and scratches during daily use and transportation, greatly enhancing the glass tube's resistance to damage, ensuring the normal use of the oxygen inhaler and the patient's treatment safety. During installation, a snap-fit ​​sleeve facilitates the transition connection. The upper and lower connecting tubes accommodate various connection specifications. Both the upper section connects to the glass tube, and the lower section connects to the base, using knob screws. Disassembly and assembly are simple, requiring only the removal and installation of these screws, allowing medical personnel to quickly and easily remove and install the protective sleeve. This design simplifies and expedites operations when periodically cleaning the glass tube or replacing spare parts, saving time and labor costs and improving work efficiency. Especially in emergencies, it enables rapid maintenance and repair, ensuring the timely and normal use of the oxygen inhaler. Furthermore, the easily removable protective sleeve allows medical personnel to thoroughly clean the glass tube periodically, removing any dust, stains, and other impurities, ensuring clear graduations and improving measurement accuracy. It also allows for the timely detection of potential problems with the glass tube, such as minor cracks, enabling prompt replacement and preventing oxygen supply disruptions due to glass tube damage, thus ensuring the long-term stable operation of the equipment.

[0033] Furthermore, observation window 3 is a vertically oriented strip-shaped opening. The observation window opening is located on the protective sleeve at the corresponding scale line position, allowing medical personnel to clearly read the flow meter scale without removing the protective sleeve, facilitating real-time monitoring of oxygen flow. Scale lines 11 are distributed on one side of the strip-shaped opening, corresponding to the scale lines on the flow meter's glass tube. This scale line structure facilitates further precise observation of the position within the flow meter.

[0034] Furthermore, the elastic shock-absorbing sleeve 4 includes a sleeve body 41 made of rubber, with an opening 42 on one side corresponding to the observation opening 3. The elastic shock-absorbing sleeve is fitted over the protective sleeve, and this sleeve also has an opening corresponding to the observation opening, which does not affect the observation scale and further enhances the shock absorption effect. The remaining surfaces of the elastic shock-absorbing sleeve are distributed with spaced, integral rubber ribs. When subjected to external impact, these ribs deform, absorbing and dispersing the impact energy, reducing the vibration transmitted to the protective sleeve and the glass tube, thereby reducing the risk of the glass tube breaking due to vibration. In addition, the slots formed by the partitions inside the protective sleeve can hold foam or rubber clips. When the outer layer is impacted, these clips absorb the remaining energy, further reducing the vibration transmitted to the flow meter, providing multi-layered shock absorption protection for the glass tube, and greatly improving the stability and safety of the glass tube. Multiple outwardly protruding rubber ribs 43 are distributed on the outer surface of the sleeve body 41, and these ribs 43 are integrally formed with the sleeve body 41.

[0035] Furthermore, the depth of the groove 5 is less than the distance between the inner wall of the protective sleeve 1 and the outer wall of the flowmeter glass tube. The buffer block 6 is a foam block or a rubber block, and both its inner and outer surfaces are arc-shaped surfaces that fit tightly against the outer wall of the flowmeter glass tube and the inner wall of the protective sleeve 1. Through the structure of the buffer block, on the one hand, it provides direct buffering protection for the glass tube, and on the other hand, it is set in the space between the glass tube and the protective sleeve to absorb residual energy, thereby reducing the vibration transmitted to the flowmeter and greatly improving the stability and safety of the glass tube.

[0036] Therefore, through the aforementioned multiple protective measures, the occurrence of glass tube breakage due to impact, vibration, and other reasons is effectively reduced, extending the service life of the glass tubes and decreasing the frequency of replacement. This not only saves the cost of purchasing new glass tubes but also reduces maintenance and downtime costs caused by equipment failure, thereby lowering operating costs for medical institutions.

[0037] Furthermore, the protective cover design makes oxygen inhaler maintenance more convenient, ensuring the equipment remains in good operating condition, reducing downtime due to equipment damage, and improving equipment utilization. Medical institutions can make fuller use of existing oxygen inhaler resources to meet the treatment needs of more patients, thereby improving the efficiency and quality of medical services.

[0038] Furthermore, the comprehensive protective design avoids the risk of glass shards flying after the glass tube breaks, preventing secondary injuries to patients and medical staff and providing a safer treatment environment for patients. Especially in emergency situations such as first aid, it ensures the continuity and stability of oxygen supply, providing strong protection for patients' lives. The elastic shock-absorbing sleeve and rubber ribs reduce vibration and noise generated during equipment operation to a certain extent, creating a relatively quiet and comfortable treatment environment for patients, helping to alleviate their anxiety and improve their treatment experience and comfort.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
