The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The specific structure of the pipe-setting rotation measuring mechanism according to the embodiment of the present invention will be described with reference to fig. 1 to 3.
As shown in fig. 1-3, the utility model discloses a put a tub rotation measuring mechanism includes casing 1, rotating assembly 2, locating part 3, trigger 4 and response piece 5, inject installation cavity 14 in the casing 1, rotating assembly 2 rotationally establishes in installation cavity 14, inject in rotating assembly 2 and put the pipe passageway 2a, it is configured to hold the simulation medical tube to put pipe passageway 2a, locating part 3 links to each other or locating part 3 and rotating assembly 2 integrated into one piece with rotating assembly 2, locating part 3 ends to support on the simulation medical tube, drive rotating assembly 2 through locating part 3 when the simulation medical tube rotates and rotate, trigger 4 establishes in installation cavity 14, response piece 5 establishes in installation cavity 14. The rotating assembly 2 is provided with a driving protrusion 221, and when the rotating assembly 2 rotates, the driving protrusion 221 can drive the triggering part 4 to trigger the sensing part 5.
It can be understood that, in the actual use process, the operator penetrates the simulated medical tube into the tube inserting channel 2a, the limiting member 3 will be stopped against the simulated medical tube, and if the operator rotates the simulated medical tube at this time, the simulated medical tube will drive the limiting member 3 and the rotating assembly 2 connected with the limiting member 3 to rotate, so that the driving protrusion 221 on the rotating assembly 2 drives the triggering member 4 to move, and the triggering member 4 triggers the sensing member 5. Therefore, the control system electrically connected with the sensing piece 5 can sense that the operator rotates the simulated medical tube. On the contrary, if the operator inserts or extracts the simulated medical tube into or from the tube insertion channel 2a only along the axial direction of the tube insertion channel 2a after inserting the simulated medical tube into the tube insertion channel 2a, the limiting member 3 will not rotate, and the corresponding rotating assembly 2 and the corresponding trigger member 4 will not move, that is, the sensing member 5 will not be triggered at this time, and then the control system of the device can determine that the operator does not rotate the simulated medical tube, that is, the operation of the operator does not meet the investigation requirement. The utility model discloses whether the operator rotates simulation medical treatment pipe is judged to the form that well adoption trigger 4 triggered response piece 5, and such structure is very simple and circuit logic is also very simple to put tub rotation measuring mechanism's manufacturing cost has been reduced. In addition, because the limiting part 3 is stopped against the simulated medical tube, the limiting part 3 can be better driven to rotate when the medical tube is put to rotate, and the measurement reliability of the tube-putting rotation measuring mechanism is ensured.
The utility model discloses put a tub rotation measuring mechanism owing to have and end to support locating part 3 on simulation medical treatment pipe, can drive locating part 3 and runner assembly 2 when having guaranteed better that simulation medical treatment rotates and rotate to put tub rotation measuring mechanism's measurement reliability has been guaranteed better. In addition, the judgment on the rotation of the simulated medical tube is realized by adopting the mode that the triggering part 4 triggers the sensing part 5, so that the mechanical mechanism and the control logic of the tube placing rotation measuring mechanism are simplified, and the production cost of the tube placing rotation measuring mechanism is reduced.
It should be noted that, in the present invention, the limiting member 3 is connected to the rotating assembly 2 or the limiting member 3 is integrally formed with the rotating assembly 2. That is, the limiting member 3 and the rotating component 2 may be two separate parts, and the limiting member 3 may also be a part of the rotating component 2.
In some embodiments, as shown in fig. 3, there are two triggering members 4 and two sensing members 5, two triggering members 4 are axisymmetric with respect to the rotation axis of the rotating assembly 2, and two sensing members 5 are axisymmetric with respect to the rotation axis of the rotating assembly 2. It will be appreciated that in practice the operator may rotate the dummy tube in different directions, and therefore the trigger member 4 and sensing member 5 are provided in two, with two trigger members 4 being axisymmetric about the axis of rotation of the rotating assembly 2 and two sensing members 5 being axisymmetric about the axis of rotation of the rotating assembly 2. Therefore, no matter the operator rotates the simulated medical tube clockwise or counterclockwise, the driving protrusion 221 on the rotating assembly 2 can drive one triggering part 4 to rotate, so that the triggering part 4 triggers the sensing part 5. That is, the control system electrically connected to the sensing member 5 can sense whether the operator rotates the dummy medical tube in any direction. Therefore, the user needs are well met.
In some specific embodiments, as shown in fig. 3, the driving protrusions 221 are plural, and the plural driving protrusions 221 are uniformly spaced along the circumferential direction of the rotating assembly 2. It will be appreciated that if there is only one drive protrusion 221, it may cause the operator to rotate a large angle to sense that the control system electrically connected to the sensing member 5 has rotated the simulated medical tube, which may reduce the user experience to some extent. Therefore, in the embodiment of the utility model, the drive protrusion 221 is a plurality of, and the rotation of simulating medical treatment pipe can be sensed to the control system who is connected with response piece 5 electricity when the operator rotates relatively less angle like this to user's user demand has been satisfied betterly.
In some embodiments, as shown in fig. 2 to 3, the rotating assembly 2 includes a rotating member 21 and a rotating member 22, a fitting hole 211 is provided on a peripheral wall of the rotating member 21, the limiting member 3 is rotatably provided in the fitting hole 211, a rotation axis of the limiting member 3 is perpendicular to a rotation axis of the rotating member 21, a part of the limiting member 3 extends into the tube placing passage 2a and abuts on the simulated medical tube, the rotating member 22 is connected to one end of the rotating member 21, and a driving protrusion 221 is provided on an outer peripheral surface of the rotating member 22. It can be understood that, since the operator can not only rotate the simulated medical tube during the actual operation, but also insert or extract the simulated medical tube along the tube insertion channel 2a, in the embodiment, the limiting member 3 can rotate relative to the rotating member 21, and the rotation axis of the limiting member 3 is perpendicular to the rotation of the rotating member 21, so that when the operator inserts or extracts the simulated medical tube along the axial direction of the tube insertion channel 2a, the limiting member 3 can rotate under the action of the simulated medical tube, that is, the limiting member 3 does not interfere with the normal insertion and extraction of the simulated medical tube. When the operator rotates the simulated medical tube, the limiting part 3 is stopped against the simulated medical treatment, and the rotation axis of the limiting part 3 is perpendicular to the rotation of the rotating part 21, so that the limiting part 3 does not rotate relative to the simulated medical tube, but the rotating part 21 is driven to rotate under the action of the simulated medical tube. Therefore, the limiting part 3 can stably drive the rotating part 21 and the simulation medical tube to rotate simultaneously when the simulation medical tube rotates, and adverse effects of the limiting part 3 on the simulation medical tube when the simulation medical tube is inserted or pulled out are avoided. And with the rotating assembly 2 split into rotating member 21 and rotation piece 22, set up locating part 3 on the rotating member 21, be equipped with drive protruding 221 on the rotation piece 22, can make the structure of two spare parts simple relatively like this to reduce rotating assembly 2's manufacturing cost. Of course, in other embodiments of the present invention, the rotating assembly 2 may be a complete component, and the limiting member 3 and the driving protrusion 221 are both disposed on the complete component.
In some specific embodiments, there are three fitting holes 211, the three fitting holes 211 are uniformly distributed along the circumferential direction of the rotating member 21, and one limiting member 3 is fitted in each fitting hole 211. It can be understood that, the locating part 3 is three, and can guarantee well that the locating part 3 drives the effect that revolving part 21 rotated along the circumferential direction evenly distributed of revolving part 21, has avoided when simulation medical treatment pipe rotates, and the condition that revolving part 21 does not rotate takes place to put pipe rotation measuring mechanism's measurement reliability has been improved. Of course, in other embodiments of the present invention, the number of the limiting members 3 may not be limited to three in this embodiment, but may be other numbers according to actual needs.
In some alternative embodiments, the position-limiting member 3 is a roller. The outer peripheral surface of the limiting part 3 is a cambered surface, so that the adverse effect of the limiting part 3 on the simulation medical tube when the simulation medical tube is inserted or pulled out can be further reduced, and the influence of the tube placing rotation measuring mechanism on the normal insertion and pulling-out of the simulation medical tube can be reduced to the maximum extent. Of course, in other embodiments of the present invention, the cross-sectional shape of the limiting member 3 may also be formed into other arbitrary shapes, such as an oval shape, a square shape, and the like, and is not limited to the circular shape of the embodiment.
In some alternative embodiments, as shown in fig. 2 to 3, the rotating member 22 is provided with a fitting hole 222, one end of the rotating member 21 is fitted in the fitting hole 222, and both the inner peripheral wall of the fitting hole 222 and the rotating member 21 are provided with rotation preventing planes. It can be understood that, when the simulated medical tube rotates, the simulated medical tube can drive the rotating member 21 to rotate through the limiting member 3, the rotating member 21 needs to drive the rotating member 22 to rotate synchronously therewith, and the driving protrusion 221 on the rotating member 22 can drive the triggering member 4 to rotate. Therefore, it is necessary to ensure that the rotating member 21 and the rotating member 22 do not rotate relatively, in this embodiment, since the inner peripheral wall of the assembling hole 222 and the rotating member 21 are both provided with the anti-rotation planes, the relative rotation between the rotating member 21 and the rotating member 22 is better avoided, and thus the measurement reliability of the tube-setting rotation measuring mechanism of this embodiment is ensured. Of course, in other embodiments of the present invention, the fitting hole 222 may be directly formed as a polygonal hole such as a square hole, and the end of the corresponding rotating member 21 extending into the fitting hole 211 is formed as a polygonal shaft such as a square shaft, or the rotating member 21 and the rotating member 22 are prevented from rotating relative to each other by a radial pin.
In some embodiments, the rotating shaft of the triggering member 4 is provided with a return elastic member (not shown), and the return elastic member is configured to drive the triggering member 4 to move in a direction away from the sensing member 5. It will be appreciated that when the drive projection 221 is disengaged from the trigger 4, the trigger 4 needs to return to its original position to await the next trigger. In this embodiment, the rotating shaft of the triggering member 4 is provided with a resetting elastic member, so that when the driving protrusion 221 drives the triggering member 4 to rotate to trigger the sensing member 5, the resetting elastic member deforms and stores energy, and when the simulated medical tube continues to rotate to separate the triggering member 4 from the driving protrusion 221, the triggering member 4 returns to the original position under the action of the resetting elastic member to wait for the next triggering. Therefore, the automatic reset of the trigger piece 4 is better realized, and the function that the pipe placing rotation measuring mechanism of the embodiment can repeatedly measure the rotation is realized.
In some embodiments, as shown in fig. 2, the housing 1 includes a front shell 11, a rear cover 12 and an intermediate plate 13, the rear cover 12 is fastened to the front shell 11 to form a mounting cavity 14, the intermediate plate 13 is fitted to the front shell 11, the intermediate plate 13 divides the mounting cavity 14 into a first sub-cavity 141 and a second sub-cavity 142, one end of the rotating assembly 2 is located in the first sub-cavity 141, the other end of the rotating assembly passes through the intermediate plate 13 to enter the second sub-cavity 142, and the triggering element 4 and the sensing element 5 are located in the second sub-cavity 142. It can be understood that the triggering element 4 and the sensing element 5 are located in the second sub-cavity 142, so that the triggering element 4 and the sensing element 5 can be better protected, and the measurement reliability of the pipe placing rotation measuring mechanism can be ensured.
