Description

Technical Field

[0001] This utility model relates to the field of human necessities, and more particularly to the field of medical auxiliary equipment, specifically a tracheostomy tube restraint device. Background Technology

[0002] A tracheotomy involves cutting open the cervical trachea and inserting a tracheostomy tube. It is a common procedure to relieve respiratory distress caused by laryngeal origin, respiratory dysfunction, or lower respiratory tract secretions. The tracheostomy tube is secured around the patient's neck with a tracheostomy tube fixation strap. This strap can sometimes cause neck skin complications such as eczema, ulcers, and even erosion and bleeding, increasing patient suffering, the infection rate of the tracheostomy wound, and even potentially leading to lung infections that could endanger the patient's life.

[0003] Currently, in clinical practice, tracheostomy tubes are secured by wrapping a gauze strap or cotton rope around the back of the neck, passing it through the fixation hole in the front of the neck, and tying a knot with a tightness of about one finger's width. This type of fixation has the following problems during use:

[0004] 1. The fixation straps at both ends are secured by knots, making replacement very inconvenient and preventing easy adjustment of the tightness of the tracheostomy tube fixation straps. If the straps are too loose during use, the tracheostomy tube may dislodge completely or partially; if the straps are too tight, it can cause pressure sores or skin damage on the neck. Furthermore, some patients with extensive burns undergoing tracheostomy experience significant neck effusion and increasing swelling. While the swelling gradually subsides after 72 hours, frequent adjustments to the tracheostomy tube fixation straps are necessary during this period, placing a heavy workload on medical staff.

[0005] 2. Because the existing fixation straps use gauze straps or ordinary cotton ropes, these materials can become damp and hard when exposed to the patient's exudate or sweat, which can easily lead to infection and swelling, affecting the patient's comfort.

[0006] 3. It is impossible to intuitively know the tightness of the fixation belt. For patients with neck swelling, it is also impossible to quantify and record the tightness of the fixation belt and the frequency of adjustment, making it difficult to intuitively adjust and record the tightness of the fixation belt. Utility Model Content

[0007] The purpose of this utility model is to provide a tracheostomy tube restraint device, which solves the technical problems in the prior art such as inconvenient adjustment of the tension of the fixing strap, easy soaking of the fixing strap by seepage and sweat leading to dampness, infection and swelling, and inability to intuitively know the tension of the fixing strap.

[0008] A tracheostomy tube restraint device includes a housing, a sleeve extending through the front and rear of the housing, and a circular wheel core inside the housing. The inner ring of the wheel core is coaxially rotatably connected to the outer ring of the sleeve. A first gear is coaxially fixed on the front side of the wheel core. Two or more pin holes are formed around the axis of the wheel core on the front side of the wheel core, the perpendicular distance between the central axis of the pin holes and the central axis of the wheel core is greater than the perpendicular distance between the outer circumference of the first gear and the axis of the wheel core. A binding rope is included. A first opening is formed on one side of the outer circumference of the housing, and a locking device is formed on the other side of the outer circumference. The device includes a groove; one end of the binding rope is provided with a buckle, which is detachably engaged with the groove; a winding groove is formed around the outer circumference of the wheel core, and the other end of the binding rope passes through the first opening and is fixedly connected in the winding groove; it includes a deflector and a second gear, which are coaxially fixedly connected by a rotating shaft; the rotating shaft is rotatably connected to the second opening; the second gear is meshed with the first gear, and an axial through hole is coaxially formed in the deflector, the rotating shaft, and the second gear; it includes a pin, which is slidably connected to the axial through hole, and the front end of the pin is inserted into the pin hole.

[0009] Furthermore, the pin includes a front section and a rear section, the diameter of the front section is smaller than the diameter of the rear section, and the rear section is slidably connected to the axial through hole; a limiting ring is coaxially provided at the outer end of the axial through hole, the diameter of the limiting ring is smaller than the diameter of the rear section and larger than the diameter of the front section, and the outer edge of the rear section abuts against the inner side of the limiting ring.

[0010] Furthermore, it includes two or more anti-slip mats, one side of which is connected to the binding rope via a rope groove, and the other side of which abuts against the neck of the human body.

[0011] Furthermore, the anti-slip mat is made of silicone.

[0012] Furthermore, an observation window is provided on the front side of the housing, and scale markings are provided on the front side of the wheel core around the axis.

[0013] Furthermore, the sleeve is provided with anti-slip texture.

[0014] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0015] 1. This utility model allows for convenient adjustment and fixation of the strap tension by inserting and removing the pin and rotating the dial. Compared to the knotted rope fixation method, it is easier to find the most comfortable tension for the patient. At the same time, it significantly improves nursing efficiency in clinical scenarios that require frequent tension adjustments (such as burns) and greatly reduces the nursing pressure on medical staff. In emergency situations (such as patient suffocation or resuscitation), the pin can be pulled out and the strap can be pulled out from the first opening to loosen it, thus facilitating quick removal.

[0016] 2. The anti-slip mat of this utility model can leave a certain gap between the rope and the neck. The silicone material can also prevent it from being soaked by liquids such as skin secretions, thereby preventing the rope from damaging and infecting the patient's neck skin, while improving comfort.

[0017] 3. This utility model allows observation of the scale markings on the wheel core through an observation window. Changes in the scale markings can indicate the tightness of the binding rope, thus facilitating observation, adjustment, and recording. Attached Figure Description

Detailed Implementation

[0027] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0028] Example 1

[0029] like Figures 1 to 7 As shown, this embodiment provides a tracheal tube restraint device.

[0030] It includes a housing 1, and a sleeve 101 that runs through the center of the housing 1. The sleeve 101 is integrally formed with the housing 1. The inner sidewall of the sleeve 101 is provided with anti-slip texture. The inner ring of the sleeve 101 is fitted over the gas cutting tube to prevent the gas cutting tube from shifting or slipping.

[0031] In the forward view, a first opening 104 is provided on the right side of the outer periphery of the housing 1, and a slot 103 is provided on the left side; a second opening 105 is provided on the right side of the front side of the housing 1; both the first opening 104 and the second opening 105 are connected to the inner cavity of the housing 1.

[0032] The housing 1 contains a circular wheel core 5. The inner ring of the wheel core 5 is coaxially and rotatably connected to the outer ring of the sleeve 101. The housing 1 also provides space for the wheel core 5 to rotate, thus allowing the wheel core 5 to rotate within the housing 1 via the sleeve 101. A rope groove 503 is formed around the axis of the wheel core 5, and the binding rope 2 is wound within the rope groove 503. A first gear 501 is coaxially mounted on the front side of the wheel core 5. More than thirty pin holes 502 are evenly distributed around the axis on the front side of the wheel core 5. The vertical distance between the central axis of the pin holes 502 and the central axis of the wheel core 5 is greater than the vertical distance between the outer circumference of the first gear 501 and the central axis of the wheel core 5. These pin holes 502, when inserted into the pins, position and fix the wheel core 5, thereby preventing it from rotating.

[0033] The device includes a binding rope 2, one end of which is equipped with a buckle 201. The buckle 201 is detachably engaged with a slot 103. Specifically, the buckle 201 is a cylinder with four spring beads mounted around its axis. The slot 103 is a cylindrical groove with four corresponding holes on its sidewall for the four spring beads. When the buckle 201 is inserted into the slot 103, the spring beads are engaged in the holes for secure connection. When the buckle is removed, the spring beads sink out of the holes. This type of engagement design is a conventional technology, and its principle and details will not be elaborated here. The other end of the binding rope 2 passes through the first opening 104 and is fixed in the winding groove 503. When the wheel 5 rotates, the binding rope 2 winds around the winding groove 503 along with the wheel 5, thus changing the length of the binding rope 2 by winding it up.

[0034] The device includes a dial 3 and a second gear 6, which are coaxially fixed together via a rotating shaft 8. The rotating shaft 8 passes through a second opening 105 and is rotatably connected to the housing 1. The second gear 6 meshes with a first gear 501. Therefore, rotating the dial 3 will drive the second gear 6 to rotate, which in turn drives the first gear 501 to rotate, and the first gear 501 drives the wheel core 5 to rotate, thus achieving the effect of winding up the binding rope 2. The dial 3 is located outside the housing 1, and the second gear 6 is located inside the housing 1, specifically between the inner side of the housing 1 and the front side of the wheel core 5. An axial through hole 9 is coaxially opened inside the rotating shaft 8.

[0035] It includes a pin 4, which includes a front section 401 and a rear section 402. The diameter of the front section 401 is smaller than the diameter of the rear section 402. The rear section 402 is set in the axial through hole 9 and is slidably connected to the rotating shaft 8, so that the pin 4 can be inserted and removed back and forth. The front end of the pin 4 is inserted into the pin hole 502. After the pin 4 is inserted into the pin hole 502, it can fix the position of the wheel core 5 and stop the wheel core 5 from rotating, thereby fixing the tightness of the binding rope 2. After the pin 4 is pulled out of the pin hole 502, the wheel core 5 can rotate freely. By inserting and removing the pin 4 and rotating the dial 3, this embodiment can easily adjust and fix the tightness of the strap. Compared with the knotted rope fixing method, it is easier to find the most comfortable tightness of the strap 2 for the patient. At the same time, it significantly improves the nursing efficiency in clinical scenarios that require frequent adjustment of tightness (such as burns) and greatly reduces the nursing pressure on medical staff. In emergency situations (such as patient suffocation, resuscitation, etc.), the pin 4 can be pulled out and the strap 2 can be pulled out from the first opening 104 to loosen it, thereby facilitating quick removal.

[0036] A limiting ring 301 is coaxially provided on the outer edge of the axial through hole 9. The limiting ring 301 is sleeved with the front section 401. The diameter of the limiting ring 301 is smaller than the diameter of the rear section 402 and larger than the diameter of the front section 401. The outer edge of the rear section 402 abuts against the inner side of the limiting ring 301, thereby restricting the rear section 402 of the pin 4 within the axial through hole 9 and preventing the pin 4 from coming out of the rotating shaft 8.

[0037] The device includes two anti-slip pads 7, made of soft silicone. The two pads 7 are positioned on the left and right sides of the neck, respectively. One side of each pad 7 is secured to the strap 2 via a groove with a partially or fully circular cross-section, while the other side rests against the neck. The anti-slip pads 7 create a gap between the strap 2 and the neck, and the silicone material prevents it from being soaked in skin secretions or other liquids, thus avoiding skin damage and infection caused by the strap 2, while also improving comfort.

[0038] How to use this embodiment:

[0039] 1. Pull the binding rope 2 out of the first opening 104 to make it as loose as possible, then put the cannula 101 on the tracheostomy tube, and put the binding rope 2 around the patient's neck.

[0040] 2. Rotate the dial 3. The dial 3 drives the pin 4 to rotate, the pin 4 drives the second gear 6 to rotate, and the second gear 6 drives the first gear 501 to rotate. This allows the dial 3 to drive the wheel core 5 to rotate, slowly tightening the binding rope 2 so that the tightness of the binding rope 2 meets the relevant clinical requirements for tracheostomy tube fixation (e.g., a spacing of one finger, which varies from region to region).

[0041] 3. Push the pin 4 into the housing 1. The pin 4 is inserted into the corresponding pin hole 502 to fix the wheel core 5 and prevent the wheel core 5 from rotating, thereby locking the current tightness.

[0042] 4. To untie, pull out the pin and pull out the rope 2 from the first opening 104 to achieve quick untying.

[0043] Example 2

[0044] like Figure 8 As shown, this embodiment is a preferred solution of Embodiment 1.

[0045] An observation window 102 is provided on the front side of the housing 1. The front side of the wheel core 5 is marked with graduations around its axis. These graduations can be scales, numbers, or a combination of both. The distance between the graduations and the central axis of the wheel core 5 is the same as the distance between the observation window 102 and the central axis of the wheel core 5. This allows the graduations on the wheel core 5 to be observed through the observation window 102. Changes in the graduations indicate the tightness of the binding rope 2, facilitating observation, adjustment, and recording. In some patients with extensive burns undergoing tracheotomy, there is significant neck effusion and increasing neck swelling. After 72 hours, the neck swelling gradually subsides. During this period, it is necessary to frequently adjust the tightness of the tracheostomy tube fixation strap and record the changes in tightness to help medical staff understand the swelling changes.
