In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, 2 and 3, the present embodiment provides an invasive pressure measuring device. The invasive pressure measuring device comprises a liquid storage bottle 1, a dropper 2, a fixing device and a syringe (not shown). One end of the dropper 2 is inserted into the liquid storage bottle 1 to be communicated with the liquid storage bottle 1, and the other end is communicated with the vein of the human body through the injector, thereby carrying out invasive pressure measurement on the patient. The liquid storage bottle 1 and the dropper 2 are generally matched for use, and in the same sleeve with the invasive pressure measuring device, the diameter of the neck part of the dropper 2 and the diameter of the neck part of the corresponding liquid storage bottle 1 are in a unified and corresponding standard. The fixing device is used for stabilizing the connection between the dropper 2 and the liquid storage bottle 1 and preventing the dropper 2 and the liquid storage bottle 1 from being loosened relatively or separated from each other.
The fixing device includes: the telescopic mechanism 5, two relatively parallel telescopic mechanisms 7 and two locking mechanisms 16 corresponding to the two telescopic mechanisms 7 respectively.
The tight mechanism 5 of cover is installed between liquid storage bottle 1 and burette 2. The tight mechanism 5 of cover includes upper connecting band 3, lower connecting band 4, two magic subsides 6. The upper connecting band 3 is sleeved on the bottleneck part of the liquid storage bottle 1. The lower connecting band 4 is sleeved on the tube neck part of the dropper 2. Go up connecting band 3 and lower connecting band 4 parallel arrangement each other, and the inner wall all is provided with anti-skidding coating, when two connecting bands cooperate with stock solution bottle 1, burette 2 respectively, protective coating multiplicable two connecting bands respectively with stock solution bottle 1, the frictional force between burette 2 to promote the stability of connecting. The head end and the tail end of the upper connecting belt 3 and the lower connecting belt 4 are respectively connected through two magic tapes 6. The upper connecting band 3 and the lower connecting band 4 may be made of a material having flexibility but not easily elastically deformed, and in this embodiment, the upper connecting band 3 and the lower connecting band 4 may be made of nylon cloth having a certain thickness, and have good wear resistance.
In this embodiment, each of the magic tapes 6 includes a female tape portion and a male tape portion, and the female tape portion and the male tape portion are engaged with each other. The head end and the tail end of the upper connecting belt 3 are respectively connected with the female adhesive part and the sub adhesive part of one of the magic tapes 6. The head end and the tail end of the lower connecting belt 4 are respectively connected with the female sticking part and the sub sticking part of the other magic tape 6. When in use, the female part and the sub-part of each magic tape 6 can be bonded together and can be torn to separate. Thereby when the upper connecting band 3 is hitching the bottleneck portion of the liquid storage bottle 1, the corresponding female part and the corresponding male part of the magic tape 6 can be bonded, so that the upper connecting band 3 is fixed with the liquid storage bottle 1. Similarly, the lower connecting band 4 and the dropper 2 can be fixed. The circumference of the connecting belt can be conveniently controlled in a mode of the magic tape 6; and then the upper connecting belt 3 and the lower connecting belt 4 can be matched with the liquid storage bottle 1 and the dropper 2 in kits with different specifications, and the universal liquid storage bottle has higher universality.
As shown in fig. 4 and 5, two telescoping mechanisms 7 are symmetrically disposed between the upper connecting belt 3 and the lower connecting belt 4 for adjusting the distance between the upper connecting belt 3 and the lower connecting belt 4.
Each telescopic mechanism 7 comprises a slide rail 71 and a serrated plate 72, one end of the slide rail 71 is fixed on the outer side of the upper connecting belt 3, in this embodiment, the slide rail 71 and the serrated plate 72 can be made of hard plastic materials, so that deformation is not easy to occur, and the texture is light. The slide rail 71 and the upper connecting belt 3 are of an integrated structure. One side of the slide rail 71 near the bottom is provided with a strip-shaped through opening 76. One end of the serrated plate 72 is fixed on the outer side of the lower connecting band 4, and in this embodiment, the serrated plate 72 and the lower connecting band 4 are integrated. One end of the serrated plate 72, which is far away from the lower connecting belt 4, extends into the inner wall of the slide rail 71, and the two telescopic mechanisms 7 can be respectively adjusted by adjusting the distance of the serrated plate 72 extending into the slide rail 71, so that the distance between the upper connecting belt 3 and the lower connecting belt 4 can be adjusted. One side of the sawtooth plate 72 close to the claw 75 is provided with a plurality of equidistant sawteeth, and an included angle a is formed between the non-stressed surface of the sawteeth and the extending direction of the sawtooth plate 72. The angle a is between 30 ° and 40 °. In other embodiments, the size of each sawtooth can be adjusted within a certain range according to the actual sizes of the daily dropper 2 and the liquid storage bottle 1. Correspondingly, in a certain range, the smaller the corresponding size of each saw tooth is, the higher the adjustment precision of the distance between the upper connecting band 3 and the lower connecting band 4 is; the larger the relative size of each serration, the more secure and stable the engagement of the locking mechanism 16 with the serration plate 72.
Two locking mechanisms 16 are respectively provided on the two telescopic mechanisms 7 for locking the adjusted telescopic mechanisms 7. Each locking mechanism 16 comprises a pressing plate 73, a pawl 75, an elastic element 74. The anti-skidding line of equidistance is seted up to one side of keeping away from elastic element 74 of pressing plate 73, and the anti-skidding line has improved the frictional force between finger and the pressing plate 73 when using, has promoted the ease for use. The side of the pressing plate 73 facing the slide rail 71 is hinged to the slide rail 71 by a hinge. The elastic element 74 is arranged between the pressing plate 73 and the sliding rail 71 and used for supporting the pressing plate 73, and the elastic element 74 comprises a spring and two mounting blocks. Two ends of the spring are respectively fixed with the two mounting blocks, and the end faces of the two connecting blocks are respectively fixed with the sliding rail 71 and the pressing plate 73. The cross section of the end surface of the claw 75 is triangular corresponding to the saw teeth. The claw 75 has one end fixed to a side of the pressing plate 73 facing the serrated plate 72 and the other end passing through the bar-shaped through-hole 76 and engaging with the serrated plate 72. The width of the inner wall of the strip-shaped through opening 76 is slightly larger than the width of the end of the clamping jaw 75, so that the clamping jaw 75 can pass through the strip-shaped through opening 76 conveniently. And the distance of the serrated plate 72 extending into the slide rail 71 can be adjusted by pressing the pressing plate 73 in a direction pointing to the slide rail 71 by hand to disengage the claws 75 from the serrated plate 72 against the elastic force of the elastic members 74.
When one end of the claw 75 is engaged with the sawtooth at a certain position on the sawtooth plate 72, the sawtooth plate 72 is not easy to move in a direction away from the slide rail 71 because the force-bearing surface of the sawtooth on the sawtooth plate 72 is blocked by the claw 75. Conversely, whenever the operator moves the serrated plate 72 further close to the slide rail 71 by hand, the pawl 75 is also pushed up by the serrations of the serrated plate 72 against the elastic force of the elastic member 74 due to the non-forced surface of the serrations and engages with the serrations at the next place of the serrated plate 72. Through the locking mechanism 16, the sawtooth plate 72 has the characteristic of one-way movement, and the distance between the upper connecting belt 3 and the lower connecting belt 4 is gradually reduced when the sawtooth plate is used, so that the stability of the liquid storage bottle 1 and the dropper 2 in matching is gradually increased, and the safety performance of the invasive pressure measuring device is further improved. The length of the telescopic mechanism 7 is adjusted by the lock mechanism 16. In addition, the device is suitable for different distances between the dropper 2 with different specifications and the liquid storage bottle 1, the universality of the device is further improved, and meanwhile, the device is safe, stable, durable and environment-friendly.
The working principle is as follows: before the dropper 2 is inserted into the liquid storage bottle 1, both the two sawtooth plates 72 of the present device are in a state of being separated from the two slide rails 71. The upper connecting band 3 is sleeved on the neck of the liquid storage bottle 1 in sequence, and the lower connecting band 4 is fixed on the neck of the dropper 2. The angle between the bottle mouth of the liquid storage bottle 1 and the end part of the dropper 2 is aligned, so that the end part of each sawtooth plate 72 can be aligned with the opening part of the corresponding slide rail 71, and the two sawtooth plates 72 can be simultaneously inserted into the two slide rails 71. Thereafter, while inserting the dropper 2 into the liquid storage bottle 1, the two locking mechanisms 16 are controlled to be opened, i.e., the two pressing plates 73 are pressed simultaneously against the elastic forces of the two elastic members 74 with one hand, thereby allowing the two extension mechanisms 7 to be adjusted in length. At this time, the dropper 2 is moved close to the direction of the liquid storage bottle 1, the two sawtooth plates 7 further slide in the two slide rails 71 respectively until one end of the dropper 2 is inserted into the bottle mouth of the liquid storage bottle 1, and then the two pressing plates 73 are released, so that the two locking mechanisms 16 lock the two extending mechanisms 7 respectively, and the fixing device completes the initial fixing. At this time, a certain adjustable distance may still exist between the dropper 2 and the liquid storage bottle 1, and the two sawtooth plates 72 can be further moved into the slide rails 71 without pressing the pressing plate 73 during the movement. When the sawtooth plates 72 further slide in the corresponding slide rails 71, the sawtooth plates 72 automatically push up the pressing plate 73, and the distance between the upper connecting belt 3 and the lower connecting belt 4 is further reduced every time the sawtooth plates 72 are pushed up. Until the connection between the dropper 2 and the liquid storage bottle 1 tends to be in a more stable state, and the looseness is not easy to generate.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
