Description

Respiratory tube support capable of locking

Technical Field

The invention relates to the technical field of medical instruments, in particular to a lockable respiratory tube support.

Background

For deeply unconscious/anesthetized patients, ventilators are essential devices to sustain their lives. Wherein, the breathing machine drives the unconscious patient to breathe through inserting the breathing tube in patient's oral trachea mainly. When the patient is in a deep coma/anesthesia process, the upper and lower jaws of the patient are often involuntarily bitten together, so that the breathing tube is bitten off. Therefore, in the actual operation process, a relatively hard plastic bracket is often sleeved on the breathing tube, so that the patient is occluded on the bracket. During the use process, we find that: although the support can effectively prevent a patient from biting off the breathing tube, the support is placed in the mouth of the patient and causes certain discomfort to the patient, so that when the patient is in a coma state, the support is involuntarily propped against the support by the tongue, and the support is separated from the upper jaw and the lower jaw of the patient. Therefore, to solve this problem, the conventional method adopts the following schemes: the bracket is fixedly connected with two connecting ropes which are respectively articulated with the ears of the patient, so that when the bracket is plugged between the upper jaw and the lower jaw of the patient, the bracket is fixed with the head of the patient through the connecting ropes, and the bracket is prevented from being separated along with the propping of the tongue of the patient. However, this method still has a certain disadvantage because the length of the connecting rope is fixed in this method, and the distance from the ear to the oral cavity of each patient is different, so it is difficult to ensure that the connecting rope is in a tight state when the bracket is between the upper and lower jaws of the patient. Meanwhile, in order to ensure that the strength of the connecting rope can withstand the unconscious propping action of a patient for many times, the connecting rope is mainly a plastic rope with certain hardness, and the length of the connecting rope is difficult to shorten in a knotting mode.

Disclosure of Invention

In summary, the technical problems solved by the present invention are: the breathing tube support has the advantages that the length of the connecting rope extending out of the support body can be adjusted and locked, so that the breathing tube support can be suitable for different patients, and the connecting rope is in a tight state when the breathing tube support is used.

The scheme adopted by the invention for solving the technical problems is as follows:

a lockable respiratory tube support comprises a support body in a cuboid shape, wherein the top of the support body is provided with respiratory tube clamping grooves which extend along the length direction of the support body and penetrate through the front end and the rear end of the support body, the respiratory tube support also comprises two groups of connecting components which are symmetrically arranged on the left side and the right side of the support body, each group of connecting components comprises a hanging lug, a connecting rope and a locking connecting mechanism, the locking connecting mechanism mainly comprises a containing cylinder and at least three rotary cylinders, the left side and the right side of the support body are respectively concavely provided with containing grooves which extend along a first direction and are sealed at two ends, each containing cylinder and each rotary cylinder can be arranged and contained in the containing grooves in a rotating way around the axis of the containing cylinder along the first direction, the rotating center lines of the containing cylinder and each rotary cylinder are perpendicular to the first direction, and the containing cylinder and each rotary cylinder can slide back and forth along the extending direction, one end of the connecting rope is connected with the hanging lug, the other end of the connecting rope sequentially penetrates through the rotary drums and is fixedly connected with the storage drum after being wound on the storage drum, the locking and connecting mechanism further comprises an elastic element which is used for enabling the storage drum and the rotary drums to slide along the extending direction of the storage groove and to be mutually extruded together so as to clamp the connecting rope, and the storage drum can be abutted against the end face of the storage groove under the action of the elastic element.

Further, the first direction is the length direction of the bracket body.

Furthermore, the accommodating groove is internally provided with a sliding groove which extends in parallel along the extending direction of the accommodating groove, and the end parts of the accommodating cylinder and the rotary cylinder extend into the sliding groove to be in sliding fit with the sliding groove.

Furthermore, the elastic element is a compression spring, the compression spring is accommodated in the accommodating groove and is positioned on one side of the rotary drum, which is far away from the accommodating cylinder, and two ends of the compression spring are respectively abutted with the end face of the sliding groove and the periphery of the adjacent rotary drum.

The end of the compression spring is abutted against the periphery of the rotary drum through the shifting piece, and the shifting piece is in sliding fit with the accommodating groove and forms a handheld part extending out of the accommodating groove.

Furthermore, an annular groove for the connection rope to pass through is concavely arranged on the periphery of the rotary drum abutted to the poking sheet.

Furthermore, a through hole for the connecting rope to pass through is formed in the plectrum.

Furthermore, the number of the sliding grooves is two, and the two sliding grooves are symmetrically arranged on the side walls of the containing groove along the extending direction of the containing groove.

Furthermore, the connecting rope is in a belt shape, a plurality of convex buckling pieces are arranged on the inner surface and the outer surface of the part of the connecting rope extending into the containing groove, the plurality of buckling pieces are alternately distributed on the inner surface and the outer surface of the connecting rope along the length direction of the connecting rope, and the buckling pieces are made of elastic materials.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

(1) the length of the connecting rope extending out of the support body can be adjusted by arranging the storage barrel, so that the connecting rope is suitable for different patients, the rotating barrel is matched to clamp the connecting rope, the length of the connecting rope extending out of the support body is locked, the head of the patient and the support body are relatively fixed during use, and the situation that the support body is accidentally pushed out of the space between the upper jaw and the lower jaw due to coma of the patient is avoided.

(2) When each rotary drum extrudes and clamps the connecting rope, the wrap angle between the connecting rope and the rotary drum is increased. The friction to which the connecting cord is subjected is therefore also increased, so that the locking effect on the connecting cord when the drums are pressed against one another is further optimized.

Example 1

As shown in fig. 1 to 5, the lockable respiratory tube support provided in this embodiment 1 includes a support body 1 in a rectangular shape, the top of the support body 1 is provided with respiratory tube slots 2 extending along a length direction thereof and penetrating through front and rear ends thereof, and further includes two sets of connecting components symmetrically disposed on left and right sides of the support body 1, each set of connecting components includes a hanging lug 12, a connecting rope 3 and a locking connecting mechanism, the locking connecting mechanism is mainly composed of a storage cylinder 5 and at least three rotary drums 6, the left and right sides of the support body 1 are respectively concavely provided with storage grooves 4 extending along a first direction and having two closed ends, each storage cylinder 5 and each rotary drum 6 are sequentially rotatably arranged around an axis thereof along the first direction and are accommodated in the storage grooves 4, and rotation center lines of the storage cylinder 5 and each rotary drum 6 are perpendicular to the first direction, the receiving cylinder 5 and each rotary cylinder 6 can slide back and forth along the extending direction of the receiving groove 4 and are extruded together, one end of the connecting rope 3 is connected with the hanging lug 12, the other end of the connecting rope sequentially passes through each rotary cylinder 6 and is fixedly connected with the receiving cylinder 5 after being wound on the receiving cylinder 5, the locking connecting mechanism further comprises an elastic element which is used for enabling the receiving cylinder 5 and the rotary cylinder 6 to slide along the extending direction of the receiving groove 4 and be extruded together so as to clamp the connecting rope 3, and the receiving cylinder 5 can be abutted against the end face of the receiving groove 4 under the action of the elastic element.

Specifically, when the present embodiment 1 is used, the breathing tube is firstly clamped in the breathing tube clamping groove 2, and then the bracket body 1 is inserted into the mouth of the patient and positioned between the upper jaw and the lower jaw; at this time, the connecting rope 3 is continuously pulled out from the storage cylinder 5, and the elastic element is compressed, so that the gaps among the rotary drums 6 and between the storage cylinder 5 and the rotary drums 6 are enlarged, the connecting rope 3 can normally pass through, and the length of the connecting rope 3 extending out of the bracket body 1 is adjusted.

When the part of the connecting rope 3 pulled out of the accommodating groove 4 reaches a proper length, the elastic element is reset, and the rotary drums 6 are mutually extruded together under the driving of the elastic element to clamp the connecting rope 3, so that the connecting rope 3 is locked. At this time, the length of the connecting rope 3 extending out of the receiving groove 4 and the bracket body 1 is fixed, and the bracket body 1 does not extend

It will be appreciated that, as the connecting cord 3 passes around the respective drums 6 in turn, the wrap angle between the connecting cord 3 and the drums 6 increases as the respective drums 6 are pressed against each other. The friction to which the connecting cord 3 is subjected is therefore also increased, so that the locking effect on the connecting cord 3 when the drums 6 are pressed against one another is further optimized.

Meanwhile, more importantly, in the traditional mode, although the length of the connecting rope 3 can be knotted, the purpose of shortening the length of the connecting rope 3 extending out of the bracket body 1 is achieved. But after knotting the connecting string 3 is fixed with respect to the stent body 1. The connecting string 3 is easily broken when the force of pushing against the tongue of the patient is large. In the embodiment 1, the length of the connecting rope 3 is not completely fixed, and if the pushing force of the tongue of the patient is too large, the connecting rope 3 can still extend out of the receiving cylinder 5 against the clamping action of the rotary cylinder 6 and the friction force thereof. Therefore, the present embodiment 1 can effectively avoid the occurrence of the breakage of the connecting cord 3.

More specifically, in the embodiment 1, the first direction is a length direction of the stent body 1, and the number of the rotating cylinders 6 is specifically 3, so as to reduce the manufacturing cost.

In this embodiment 1, the specific structure for realizing the function that the drum 6 and the storage cylinder 5 can rotate around their axes and can slide along the extending direction of the storage tank 4 is as follows: the accommodating groove 4 is internally provided with a sliding groove 7 which extends in parallel along the extending direction, and the end parts of the accommodating cylinder 5 and the rotary drum 6 extend into the sliding groove 7 to be in sliding fit with the sliding groove 7. More specifically, the number of the sliding grooves 7 is two, so that the two ends of the storage barrel 5 and the two ends of the drum 6 can respectively and slidably extend into the sliding grooves. In addition, in this embodiment 1, the elastic element is a compression spring 8, the compression spring 8 is accommodated in the accommodating groove 4 and is located on the side of each drum 6 away from the accommodating cylinder 5, and both ends of the compression spring 8 respectively abut against the end surface of the sliding groove 7 and the outer periphery of the adjacent drum 6, so as to realize the function of pressing each drum 6 against each other and abutting the accommodating cylinder 5 against the end of the accommodating groove 4 as the drum 6 moves. It is to be noted that it is obvious to those skilled in the art that the prior art has an existing structure which can realize the same function of the above structure without creative efforts. Meanwhile, in order to improve the movement stability of the drum 6 and/or the storage tube 5, in the present embodiment 1, the number of the sliding grooves 7 is two, and the two sliding grooves 7 are symmetrically arranged on the side walls of the accommodating groove 4 along both sides of the extending direction thereof.

In the present embodiment 1, the user releases the limiting function of the connection cord 3 passing through the drum 6 and the storage tube 5 mainly by compressing the elastic element. In a preferred embodiment, in embodiment 1, a dial 9 is further included, the dial 9 is fixedly connected to an end of the compression spring 8, the end of the compression spring 8 is abutted to the drum 6 through the dial 9, the dial 9 is in sliding fit with the accommodating groove 4 and forms a handheld portion extending out of the accommodating groove 4, and the dial 9 is further provided with a through hole 10 for the connection rope 3 to pass through. The advantages of this arrangement are: the user only needs to drive the end of the compression spring 8 to move by pushing or pulling the hand-held part on the shifting piece 9, so as to contact or open the limit of the connecting rope 3.

Further, in order to prevent the connecting rope 3 from being displaced and jammed into the sliding groove 7 during use, in the present embodiment 1, as a preferred embodiment, an annular groove for the connecting rope 3 to pass through is concavely provided on the outer circumference of the drum 6 abutting against the pick 9. As shown in fig. 2, the portions of the drum 6 and the storage tube 5 inserted into the sliding grooves 7 are both in the shape of a circular shaft, and the diameters thereof are matched with the sliding grooves 7, so that the drum 6 and the storage tube 5 can rotate around their axes.

Example 2

Example 2 is substantially the same as example 1, and the main difference between the two is the connecting cord 3. In embodiment 1, the connecting cord 3 is held between the respective storage tubes 5, and is restrained by the frictional force applied thereto from the drum 6. In order to further improve the position-limiting stability of the connection rope 3 in the locked state, as shown in fig. 6, in embodiment 2, the connection rope 3 is in a belt shape, and a plurality of protruding fastening pieces 11 are disposed on the inner and outer surfaces of a portion of the connection rope 3 extending into the receiving groove 4, the plurality of fastening pieces 11 are alternately distributed on the inner and outer surfaces of the connection rope 3 along the length direction of the connection rope 3, and the fastening pieces 11 are made of an elastic material. In the locked state, if the pushing force of the patient's tongue against the frame body 1 is too large, so that the connecting rope 3 is pulled out from the receiving cylinder 5 and moves in each gap, the buckle piece 11 can push against the rotary cylinder 5 along with the movement of the connecting rope 3, and the continuous extension of the connecting rope 3 is blocked.
