Description

Technical Field

[0001] This utility model relates to the field of medical and nursing equipment, and in particular to an indwelling tube nasal fixation device. Background Technology

[0002] An indwelling catheter is a tube used in medical settings to maintain a passage or guide fluid for an extended period. It is commonly used in various medical procedures and treatments, and can be classified into several types depending on the purpose and location of use.

[0003] The fixation of the indwelling catheter is crucial. Its main purpose is to ensure that the catheter is stable inside or outside the patient's body to prevent displacement, twisting, or dislodgement, thereby ensuring the effectiveness and safety of the treatment.

[0004] Currently, existing nasal fixation devices for indwelling catheters have some shortcomings: some fixation devices use ear loops and adhesive tape to fix the catheter. However, ear loops may press on the indwelling catheter when the patient is lying down, and the bridge of the nose becomes oily due to sweat, which reduces the adhesion of the adhesive tape. Therefore, a new nasal fixation device for indwelling catheters is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a nasal fixation device for indwelling tubes, which aims to improve the problems of existing ear-hook type devices that may press on the indwelling tube when the patient is lying down, and the nasal bridge area becoming greasy due to sweat, thus reducing the adhesion effect of the tape.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a nasal fixation device for an indwelling tube, including a nasal support rod, wherein two sets of nasal support rods are provided, and a connecting rubber seat is fixedly connected between the two sets of nasal support rods. An adjustment mechanism is provided on the outer sidewall of the left nasal support rod, and a fixing component is provided at the bottom end of both sets of nasal support rods.

[0007] The adjusting mechanism includes a fixed block, a winding shaft rotatably connected to the inner wall of the fixed block, a connecting belt wound around the surface of the winding shaft, a top plate fixedly connected to the top of the outer wall of the fixed block, a rotating block rotatably connected to the top of the outer wall of the top plate, and a wedge elastically connected to the inner wall of the rotating block via a return spring.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a fixing sleeve, and the inner wall of the fixing sleeve is elastically connected to a pressing block by a limiting spring.

[0010] As a further description of the above technical solution:

[0011] The connecting strip passes through and is slidably connected to the inner wall of the fixed block, and the end of the connecting strip away from the take-up shaft is fixedly connected to the outer wall of the nose support rod on the right side.

[0012] As a further description of the above technical solution:

[0013] The rotating block is fixedly connected to the rotation center axis of the take-up shaft, and the wedge block is slidably connected to the inner wall of the rotating block.

[0014] As a further description of the above technical solution:

[0015] One end of the reset spring is fixedly connected to the surface of the wedge block, and the other end of the reset spring is fixedly connected to the inner wall of the rotating block.

[0016] As a further description of the above technical solution:

[0017] The surface of the top plate is provided with a slot, and the bottom end of the outer wall of the wedge block is engaged with the inner wall of the slot.

[0018] As a further description of the above technical solution:

[0019] The fixing sleeve is fixedly connected to the bottom end of the outer wall of the nose support rod, and the clamping block is slidably connected to the inner side wall of the fixing sleeve.

[0020] As a further description of the above technical solution:

[0021] One end of the limiting spring is fixedly connected to the inner side wall of the fixed sleeve, and the other end of the limiting spring is fixedly connected to the outer side wall of the clamping block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the length of the connecting belt can be flexibly adjusted according to the head circumference of different patients through the cooperation of the winding shaft and the connecting belt. With the help of the fixing action of the wedge and the top plate slot, it can be accurately and stably fixed in the appropriate position, ensuring that the device fits the patient's head. This allows the two sets of nasal support rods to fit against the bridge of the nose to support the indwelling tube, avoiding the problem of oil easily getting on the bridge of the nose and resulting in insufficient fixation, which is a problem with the traditional use of tape.

[0024] 2. In this utility model, the fixing component utilizes the synergy of the clamping block and the limiting spring to reliably fix the indwelling tube. When the indwelling tube is inserted into the fixing sleeve, it can be prevented from falling out by the automatic clamping of the clamping block, and damage to the indwelling tube caused by excessive squeezing is avoided. This ensures the accurate position and normal function of the indwelling tube in the nasal cavity and meets the strict requirements of medical care for the fixation of the indwelling tube in the nose.

[0031] 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 protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a nasal fixation device for an indwelling tube, including a nasal support rod 1. Two sets of nasal support rods 1 are provided, and a connecting rubber seat 2 is fixedly connected between the two sets of nasal support rods 1. By providing connecting rubber seats 2 for the two sets of nasal support rods 1, the entire device can be placed on the patient's nasal bridge, thereby supporting the entire nasal support rod 1. An adjustment mechanism 4 is provided on the outer sidewall of the left nasal support rod 1, and a fixing component 3 is provided at the bottom end of both sets of nasal support rods 1.

[0033] Reference Figure 1 - Figure 3The adjustment mechanism 4 includes a fixed block 41, with a winding shaft 42 rotatably connected to the inner wall of the fixed block 41. A connecting strap 5 is wound around the surface of the winding shaft 42, passing through and slidably connected to the inner wall of the fixed block 41. A slot is provided on the side wall of the fixed block 41, allowing the connecting strap 5 to pass through the interior of the fixed block 41 and be wound onto the surface of the winding shaft 42. When the entire device is worn on the patient's head, the winding of the connecting strap 5 can be adjusted by rotating the winding shaft 42, allowing the device to be adjusted according to different patients' head circumferences. The end of the connecting strap 5 away from the winding shaft 42 is fixedly connected to the outer wall of the right nasal support rod 1. A top plate 43 is fixedly connected to the top of the outer wall of the fixed block 41, and a rotating block 44 is rotatably connected to the top of the outer wall of the top plate 43. The inner wall of the rotating block 44 is open to the surface of the winding shaft 42. A wedge block 46 is elastically connected to a return spring 45. One end of the return spring 45 is fixedly connected to the surface of the wedge block 46, and the other end is fixedly connected to the inner wall of the rotating block 44. The function of the return spring 45 is to automatically reset the wedge block 46 after it is squeezed and manually pushed upward. The rotating block 44 is fixedly connected to the rotation center axis of the winding shaft 42. The wedge block 46 passes through and slides on the inner wall of the rotating block 44. A slot is provided on the surface of the top plate 43. The bottom end of the outer wall of the wedge block 46 engages with the inner wall of the slot. The engagement between the two can fix the wedge block 46 at multiple positions on the surface of the top plate 43 as it stays with the rotating block 44, thus facilitating the fixing of multiple lengths after the winding shaft 42 drives the connecting belt 5 to be wound.

[0034] Reference Figure 1 and Figure 4 The fixing component 3 includes a fixing sleeve 31. The inner wall of the fixing sleeve 31 is elastically connected to a pressing block 33 via a limiting spring 32. One end of the limiting spring 32 is fixedly connected to the inner side wall of the fixing sleeve 31, and the other end of the limiting spring 32 is fixedly connected to the outer side wall of the pressing block 33. The surface of the pressing block 33 is provided with a slope. By providing its slope, the indwelling tube can be inserted into the interior of the fixing sleeve 31 from the bottom slope of the pressing block 33, thereby squeezing the pressing block 33 to move on the inner wall of the fixing sleeve 31 and compressing the limiting spring 32. Thus, the pressing block 33 is subjected to the elastic action of the limiting spring 32, thereby pressing the indwelling tube that passes through the interior of the fixing sleeve 31. The fixing sleeve 31 is fixedly connected to the bottom end of the outer wall of the nasal support rod 1, and the pressing block 33 is slidably connected to the inner side wall of the fixing sleeve 31.

[0035] Working principle: When fixing the catheter, first manually move the wedge 46 upwards. The wedge 46 slides upwards on the inner wall of the rotating block 44, stretching the return spring 45 and disengaging it from the slot of the top plate 43, thus releasing the restriction on the rotation of the rotating block 44 (i.e., the winding shaft 42). Then, rotate the rotating block 44. Since the rotating block 44 is fixedly connected to the rotation center axis of the winding shaft 42, the winding shaft 42 will rotate synchronously, performing winding or unwinding operations on the connecting band 5. If the length of the connecting band 5 needs to be shortened to accommodate patients with smaller head circumferences, the winding shaft 42 winds up the connecting band 5; if... To extend the length, rotate the unwinding mechanism in the opposite direction. Once the connecting band 5 is adjusted to the appropriate length, release the wedge 46. The wedge 46 will reset under the elastic restoring force of the return spring 45, and its outer bottom end will be inserted into the corresponding slot on the surface of the top plate 43, fixing the position of the rotating block 44 (winding shaft 42) and thus fixing the length of the connecting band 5. This ensures that the device can be stably worn on the patient's head without affecting the effectiveness and patient comfort due to the connecting band 5 being loose or too tight. Then, place the two sets of nasal support rods 1 on the patient's nasal bridge through the connecting rubber seat 2 for support.

[0036] When fixing the indwelling tube, insert the indwelling tube into the fixing sleeve 31 from the inclined surface at the bottom of the clamping block 33. Due to the inclined surface design of the clamping block 33, the indwelling tube will squeeze the clamping block 33 during insertion, causing the clamping block 33 to slide outward on the inner wall of the fixing sleeve 31 and compress the limiting spring 32. After the indwelling tube has completely passed through the fixing sleeve 31, the clamping block 33 will return to its original position under the elastic restoring force of the limiting spring 32. Its inner wall will apply pressure to the indwelling tube, firmly fixing the indwelling tube inside the fixing sleeve 31, preventing the indwelling tube from shaking, shifting or falling out during use, ensuring the stability of the indwelling tube in the nasal cavity, and ensuring the smooth progress of treatment or nursing. When it is necessary to remove the indwelling tube, simply pull the indwelling tube outward to overcome the pressure of the clamping block 33, and the indwelling tube can be pulled out from the fixing sleeve 31. The operation is simple and convenient, making it easy for medical staff to operate and maintain the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
