Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a device for preventing patients from adjusting oxygen flow by themselves. Background Art

[0002] During the process of emergency medical rescue, oxygen inhalation is basically required as an auxiliary treatment. The sources of oxygen for medical rescue are generally divided into two categories. The first is centralized oxygen supply, which is the hospital's integrated oxygen source. The patient takes it directly from the equipment. This is also the use of oxygen in fixed places. The second is decentralized oxygen supply, such as 120 emergency treatment or the transfer of patients within the hospital. Patients cannot use centralized oxygen supply and can only use oxygen cylinders. There are several types of decentralized oxygen cylinders. Large-capacity oxygen cylinders have special trailers, while small-capacity oxygen cylinders are basically carried on the body or in the car. An oxygen control valve is set on the oxygen cylinder, and the oxygen flow and value are adjusted and viewed through the oxygen control valve. When the oxygen control valve adjusts the oxygen flow, it is operated by turning the adjustment knob on the oxygen control valve.

[0003] Currently, when patients receive oxygen therapy through oxygen cylinders, they are often unconscious or adjust the oxygen flow they need to inhale on their own initiative. If patients adjust the required oxygen flow on their own, there will undoubtedly be certain risks to their own treatment. Therefore, in order to avoid patients adjusting the oxygen flow on their own, causing discomfort to patients and even more serious situations, this device provides a device to prevent patients from adjusting the oxygen flow on their own. Utility Model Content

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a device for preventing patients from adjusting the oxygen flow rate by themselves, so as to solve the above-mentioned technical problems.

[0005] The embodiment of the present utility model adopts the following technical solution: it includes a fixing mechanism for being sleeved and fixed on the outside of the required oxygen control valve and a limiting mechanism for limiting the rotation of the adjusting knob on the oxygen control valve. The fixing mechanism is sleeved on the outside of the required oxygen control valve by a threaded connection. Two limiting mechanisms are provided, and the two limiting mechanisms are symmetrically arranged on the fixing mechanism. The ends of the two limiting mechanisms both abut against the bottom of the adjusting knob on the oxygen control valve for adjusting the oxygen flow. The two limiting mechanisms are moved to abut against and release the bottom of the adjusting knob by rotating the thread.

[0006] Furthermore, the fixing mechanism includes a fixing ring, a fixing block, a fixing bolt and a fixing nut. The fixing ring is set in an unclosed state and is made of rubber. The fixing ring can be sleeved on the outside of the required oxygen control valve through the unclosed part. There are two fixing blocks, and the two fixing blocks are symmetrically arranged on the fixing ring. The unclosed part of the fixing ring is symmetrically provided with two protrusions and the two protrusions are both provided with through holes. The end of the fixing bolt is provided with an external thread, and the middle part of the fixing bolt passes through the two protrusions and is rotatably connected to the corresponding protrusion. The fixing nut is sleeved on the end of the fixing bolt and is threadedly connected.

[0007] Furthermore, the two limiting mechanisms each include a limiting bolt, a limiting nut and a limiting adjustment handle, the limiting bolt being arranged at the upper end of the corresponding fixed block, the upper end of the limiting bolt being provided with an external thread, the distance between the upper end of the limiting bolt and the bottom of the adjusting knob being two-thirds of the height of the limiting nut, the limiting nut being sleeved on the upper end of the limiting bolt and threadedly connected, the limiting adjustment handle being arranged at the side end of the limiting nut, the limiting adjustment handle being arc-shaped and located at the bottom of the adjusting knob, and the bottom diameter of the adjusting knob being larger than the arc diameter of the limiting adjustment handle.

[0008] Furthermore, the fixing block in the fixing mechanism is set as one, and the fixing block is set at the side end of the fixing ring and is set at ninety degrees to the fixing ring. A slot is provided on the inner side of the fixing block, and the inner diameter of the slot is larger than the outer diameter of the connecting shaft for connecting and adjusting the transmission with the adjusting knob.

[0009] Furthermore, the two limiting mechanisms are symmetrically arranged on the fixing block and face the bottom of the adjusting knob.

[0010] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0011] The utility model adopts common bolts and nuts as components of the two limiting mechanisms and the fixing mechanism, which are low in cost and can be adapted to adjusting knobs of different types and in different directions, and can play a role of limiting resistance to the adjusting knobs. At the same time, the two limiting mechanisms are relatively secretive, so that personnel can see them as a fixed device, which is easy to operate and not easy to damage, thus preventing the patient's family from arbitrarily adjusting the oxygen control valve and affecting the patient's normal treatment.

[0012] When medical staff need to adjust the oxygen flow by turning the adjustment knob, they only need to turn the two limit adjustment handles outward. After the two limit adjustment handles are turned, the corresponding limit nuts will be driven to rotate on the upper ends of the corresponding limit bolts, and the corresponding limit nuts will be moved toward the bottom of the adjustment knob through rotation, thereby disengaging the upper ends of the two limit nuts from the bottom of the adjustment knob. At this time, the medical staff can adjust the oxygen flow by turning the adjustment knob;

[0013] After the medical staff has adjusted the oxygen flow, they only need to move the two limit adjustment handles toward the inside of the adjustment knob to drive the corresponding limit nuts to rotate, and the corresponding limit nuts will move toward the bottom of the adjustment knob through rotation, so that the upper ends of the two limit nuts will re-contact the bottom position of the adjustment knob to limit the adjustment knob, avoiding the patient's family from arbitrarily adjusting the oxygen control valve and affecting the patient's normal treatment.

[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by patients of ordinary skill in the art without making any creative efforts are within the scope of protection of the present invention.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the present utility model provides a device for preventing patients from adjusting the oxygen flow rate by themselves, comprising a fixing mechanism 1 for being sleeved and fixed on the outside of a desired oxygen control valve and a limiting mechanism 2 for limiting the rotation of an adjusting knob 3 on the oxygen control valve. The fixing mechanism 1 is sleeved on the outside of the desired oxygen control valve by a threaded connection. Two limiting mechanisms 2 are provided, and the two limiting mechanisms 2 are symmetrically arranged on the fixing mechanism 1. The ends of the two limiting mechanisms 2 both abut against the bottom of the adjusting knob 3 on the oxygen control valve for adjusting the oxygen flow rate. The two limiting mechanisms 2 are moved by rotating the thread to abut against and release the bottom of the adjusting knob 3.

[0025] The two limiting mechanisms 2 and the fixing mechanism 1 in this device are both made of common bolts and nuts, which are low in cost and can be adapted to adjusting knobs 3 of different types and in different directions, and can play a role in limiting the adjusting knobs 3. At the same time, the two limiting mechanisms 2 are relatively secretive, so that people can see them as a fixed device. They are easy to operate and not easy to damage, which prevents the patient's family from arbitrarily adjusting the oxygen control valve and affecting the patient's normal treatment.

[0026] The device can also be fixed to the atomization port on the oxygen cylinder to seal the atomization port, thereby avoiding arbitrary adjustment and affecting the normal treatment of the patient.

[0027] In a further preferred embodiment of the present invention, Figure 1As shown, for the adjustment knob 3 having the same angle as the horizontal plane and being arranged upward, the fixing mechanism 1 includes a fixing ring 11, a fixing block 12, a fixing bolt 13 and a fixing nut 14. The fixing ring 11 is set in an unclosed state. The fixing ring 11 is made of rubber. The fixing ring 11 can be sleeved on the outside of the required oxygen control valve through the unclosed portion. There are two fixing blocks 12, and the two fixing blocks 12 are symmetrically arranged on the fixing ring 11. The unclosed portion of the fixing ring 11 is symmetrically provided with two protrusions 111, and the two protrusions 111 are both provided with through holes. The end of the fixing bolt 13 is provided with an external thread, and the middle part of the fixing bolt 13 passes through the two protrusions 111 and is rotatably connected to the corresponding protrusion 111. The fixing nut 14 is sleeved on the end of the fixing bolt 13 and is threadedly connected.

[0028] When fixing the device to the outside of the required oxygen control valve, first, the unclosed end of the fixing ring 11 is passed through the outside of the oxygen control valve and sleeved on the rod body. Then, the position of the fixing ring 11 is moved so that the upper ends of the two limit mechanisms 2 are both strongly against the adjusting knob 3 for adjusting the oxygen flow on the oxygen control valve. At this time, the end of the fixing bolt 13 is passed through the corresponding through holes on the two protrusions 111, and then the fixing nut 14 is threadedly connected to the end of the fixing bolt 13 and tightened.

[0029] In a further preferred embodiment of the present utility model, the two limiting mechanisms 2 each include a limiting bolt 21, a limiting nut 22 and a limiting adjustment handle 23, the limiting bolt 21 is arranged at the upper end of the corresponding fixing block 12, the upper end of the limiting bolt 21 is provided with an external thread, the distance between the upper end of the limiting bolt 21 and the bottom of the adjusting knob 3 is two-thirds of the height of the limiting nut 22, the limiting nut 22 is sleeved on the upper end of the limiting bolt 21 and threadedly connected, the limiting adjustment handle 23 is arranged at the side end of the limiting nut 22, the limiting adjustment handle 23 is arc-shaped and located at the bottom of the adjusting knob 3, and the bottom diameter of the adjusting knob 3 is larger than the arc diameter of the limiting adjustment handle 23;

[0030] When the medical staff needs to adjust the oxygen flow by turning the adjustment knob 3, they only need to turn the two limit adjustment handles 23 outward. After the two limit adjustment handles 23 are turned, the corresponding limit nuts 22 will be driven to rotate on the upper ends of the corresponding limit bolts 21, and the corresponding limit nuts 22 will be moved toward the bottom of the adjustment knob 3 through rotation, so that the upper ends of the two limit nuts 22 are out of contact with the bottom of the adjustment knob 3. At this time, the medical staff can adjust the oxygen flow by turning the adjustment knob 3;

[0031] After adjusting the oxygen flow, the medical staff only needs to turn the two limit adjustment handles 23 to the inner side of the adjustment knob 3, thereby driving the corresponding limit nuts 22 to rotate, and the corresponding limit nuts 22 will move toward the bottom of the adjustment knob 3 through rotation, so that the upper ends of the two limit nuts 22 will contact the bottom position of the adjustment knob 3 again, thereby limiting the adjustment knob 3, preventing the patient's family from arbitrarily adjusting the oxygen control valve and affecting the patient's normal treatment;

[0032] The two limiting mechanisms 2 and the fixing mechanism 1 both use common bolts and nuts, which are low in cost and can be adapted to adjusting knobs 3 of different types and in different directions. At the same time, the two limiting mechanisms 2 are concealed and are located at the bottom of the adjusting knob 3. The adjusting knob 3 can effectively block the field of vision, while the fixing mechanism 1 looks like a fixing screw at first glance. Therefore, when the patient or the patient's family adjusts the oxygen flow of the oxygen control valve at will, the patient cannot turn the adjusting knob 3 to adjust the oxygen flow, which prevents the patient's family from arbitrarily adjusting the oxygen control valve and affecting the patient's normal treatment. It also facilitates medical staff to operate very conveniently.

[0033] In a further preferred embodiment of the present invention, Figure 2 As shown, for the adjustment knob 3 to be arranged at a 90-degree angle to the horizontal plane, the fixing block 12 in the fixing mechanism 1 is provided as a single setting. The fixing block 12 is provided at the side end of the fixing ring 11 and is arranged at a 90-degree angle to the fixing ring 11. A card slot is provided on the inner side of the fixing block 12. The inner diameter of the card slot is larger than the outer diameter of the connecting shaft for connecting and adjusting the transmission of the adjustment knob 3. The two limiting mechanisms 2 are symmetrically provided on the fixing block 12 and face the bottom of the adjustment knob 3.

[0034] Due to the different layout and connection methods of the adjusting knob 3, there are generally two ways to adjust the knob 3, one is to be set at the same angle as the horizontal plane and to be upward, and the other is to be set at ninety degrees to the horizontal plane and to be sideways. By setting the fixing block 12 in the fixing mechanism 1 as one and setting it at ninety degrees to the fixing ring 11, the two limiting mechanisms 2 can be symmetrically set on the fixing block 12, so that the two limiting mechanisms 2 can be adapted to the other adjustment knob 3 set at ninety degrees to the horizontal plane, so that both layout and connection methods of the adjusting knob 3 can be used.

[0035] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of the claims of the present invention.
