Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic medical instruments, and in particular to an automatic probe replacement device for a rebound tonometer and a method for automatically aligning and filling the probe using the automatic probe replacement device. Background Art

[0002] As a commonly used intraocular pressure measuring instrument, the rebound tonometer has the advantages of being easy to operate, easy to carry, and not requiring anesthesia. Its working principle is based on electromagnetic induction. The probe is magnetized through the induction coil and driven to pop out. After the probe head contacts the eyeball, it decelerates and rebounds. At this time, the voltage change of the induction coil is detected, and a specific algorithm is used to convert the electrical signal parameters into intraocular pressure values. Traditional rebound tonometers require manual replacement of the probe, which not only increases the workload of the operator, but also poses a risk of cross-infection. In addition, the manual replacement of the probe is prone to problems such as unstable probe installation and inaccurate positioning, which in turn affects the accuracy of the measurement results. Summary of the Invention

[0003] In view of this, in order to solve the above-mentioned problems of manual replacement and filling of the traditional rebound tonometer, and to improve the efficiency of intraocular pressure measurement, on the one hand, the present invention provides an automatic probe replacement device for a rebound tonometer. By packaging a large number of probes in a probe blister packaging plate, the automatic probe feeding device automatically unfolds the packaging, and the automatic probe alignment filling device automatically adsorbs and launches the probes, the function of automatic probe replacement is realized. It not only eliminates the problems of heavy workload and cross-infection risk caused by traditional manual operation, but also saves the operator's time and improves work efficiency.

[0053] like Figure 1 As shown, the present invention provides an automatic probe replacement device for a rebound tonometer, comprising:

[0054] A probe blister pack plate 1 stores a plurality of probes 7 thereon. Figures 2-4As shown, the present application provides a specific embodiment of a probe blister packaging plate 1, which is preferably sealed by two layers of packaging sheets using a laminating process, and the strength and toughness of the two layers of packaging sheets should meet the following requirements: not broken by the tear of the roller, plastic bending to adapt to the surface of the roller arc, folding and stacking to facilitate the storage of waste packaging plates. One of the layers of the probe blister packaging plate 1 is provided with a plurality of protruding parts at equal intervals as the probe blister 10 that can store the probe 7, and the probe 7 is sealed inside the probe blister 10.

[0055] The probe automatic feeding device is used to tear the probe blister packaging plate 1 and expose the probe 7, so that the probe 7 is automatically fed in order and quantitatively. Figure 2 、 4 As shown, the present application provides a specific embodiment of a probe automatic feeding device, which includes a pair of probe conveying rollers 2 distributed on both sides of the probe blister packaging plate 1, and the rollers are driven to rotate by a first driving device (preferably a stepping motor). The probe conveying roller 2 is provided with a positioning spike 12 for inserting into the positioning hole 9. In order to facilitate the probe 7 automatic feeding device to tear the probe blister packaging plate 1 to fully expose the probe 7, and to facilitate the cooperation with the probe automatic feeding device to automatically feed the probe 7 in order and quantitatively. In the present application, a plurality of pairs of positioning holes 9 are provided on both long sides of the probe blister packaging plate 1, and the plurality of pairs of positioning holes 9 are arranged at equal intervals, and the interval is kept corresponding to the plurality of probe blisters 10. Each probe blister 10 is sealed with one probe 7 inside. The top side of the probe blister packaging plate 1 is a packaging plate opening structure 11 for easy positioning, which is formed by keeping a proper gap between the two layers of packaging structures, and the texture is relatively hard to facilitate the installation of the probe blister packaging plate 1 on the probe conveying roller 2. The probe conveying roller 2 is driven by a stepping motor, and whenever the probe 7 automatic filling is needed, the stepping motor drives the probe conveying roller 2 to rotate by an arc of the interval of the positioning hole 9, so that the probe 7 inside the probe blister 10 is exposed, and then the above-mentioned probe 7 adsorption and automatic filling is completed.

[0056] The probe conveying roller 2 is preferably a cylindrical body, and a circle of positioning spikes 12 is arranged near the upper and lower bottom surfaces of the cylinder, and the positioning spikes 12 are preferably a plurality of small conical or cylindrical protrusions. The interval of the positioning spikes 12 is the same as the interval of the plurality of positioning holes 9 on the probe blister packaging plate 1, and the number of the circle of positioning spikes 12 is determined by the diameter of the probe conveying roller 2 and the interval of the plurality of positioning holes 9. The positioning spike 12 is inserted into the positioning hole 9, and the positioning spike 12 can tear open the two layers of packaging sheets of the probe blister packaging plate 1 when the roller rotates. The probe conveying roller 2 is preferably a pair of rollers that work simultaneously and rotate in opposite directions. Figure 4From the perspective shown, the left roller is rotated counterclockwise, the right roller is rotated clockwise, and the positioning prongs 12 between the two rollers need to be kept facing each other.

[0057] As shown in the figure, Figure 2 In the present application, a probe positioning baffle 8 is further arranged above the probe automatic feeding device, which is preferably a streamlined sheet structure, and preferably 2, respectively above the probe conveying roller 2, and spatially face-to-face distributed.

[0058] The packaging plate opening structure 11 of the probe blister packaging plate 1 first contacts the probe conveying roller 2, and the positioning hole 9 on the packaging plate opening structure 11 is preferentially matched with the positioning prong 12, so that the subsequent positioning hole 9 is matched with the subsequent positioning prong 12 one by one, thereby ensuring that the subsequent probe blister packaging plate 1 can be unrolled with the rotation of the probe conveying roller 2.

[0059] The present application can realize the sealing of a large number of probes 7 and the sterile storage of a large number of probes through the design of the probe blister packaging plate 1. In cooperation with the probe automatic feeding device and the probe automatic alignment filling device, the probe 7 can be opened and replaced automatically as needed, completely avoiding touching the probe 7, and ensuring the seamless connection of the automatic feeding, alignment and filling process of the probe 7.

[0062] Efficient and ready-to-use: The probe blister 10 seals and stores a large number of probes 7, and the device realizes seamless connection of "tearing and sealing - conveying - filling", greatly improving the replacement efficiency.

[0063] Reliable structure design: double rollers rotate in opposite directions + hard opening guide design, which ensures stable traction and unrolling of the packaging plate and reduces the failure rate.

[0064] In summary, the present application automatically replaces manual operation through the probe automatic feeding device, realizes precise, stable and fast probe conveying, and significantly improves efficiency, precision, safety and reliability. It meets the needs of high-difficulty scenes such as miniaturized operation and dangerous environment operation. Through the combination of mechanical interlocking design of packaging hole-roller prong and precise driving of step motor, the core pain point of sterile and automatic replacement of medical probes is solved, and efficiency and safety are considered.

[0065] A magnetic attraction device 3 is used to attract the exposed probe 7. The magnetic attraction device 3 is preferably an electromagnet, preferably located at the top end of the internal structure of the tonometer.

[0066] A probe tip constraint structure 4 is arranged below the magnetic attraction device 3 (preferably close to the lower part of the electromagnet), used to make the tail end of the attracted probe 7 stand up. As shown in the figure, the present application provides a specific embodiment of the probe tip constraint structure 4, as follows: Figure 5

[0067] The probe tip constraint structure 4 is preferably a cuboid, with a first constraint baffle 19 at one end (the right end), a second constraint baffle 20 (e.g. a protrusion) near the first constraint baffle 19 (the left end), and a third constraint groove 21 (used to make the tail end of the probe 7 stand up) on one side of the long edge of the second constraint baffle 20. The probe 7 is attracted by the electromagnet and stands up, the head of the probe 7 is blocked by the first constraint baffle 19 and cannot slide to the right, the tail of the probe 7 is made to stand up by the second constraint baffle 20, and the middle of the probe 7 is constrained by the third constraint groove 21 and cannot slide to the left or right. The electromagnet is always powered on, so that the probe 7 always has its tail end standing down and its head close to the groove near the first constraint baffle 19. When the tail end of the probe 7 is attracted by the probe launching tube 5 with alignment function, the electromagnet is powered off and loses its magnetism, and the probe 7 will naturally slide into the probe launching tube 5 with alignment function.

[0068] A probe automatic alignment and filling device is used to collect or launch probes.

[0069] As shown in the figure, the present application provides a specific embodiment of the probe automatic alignment and filling device, as follows: Figure 6

[0070] The probe automatic alignment and filling device includes:

[0071] A probe launching tube holder 6 is driven by a second driving device, so that it has axial freedom. The second driving device is preferably a linear motor 15. A linear motor 15 is preferably installed, spatially above the probe positioning baffle 8 and below the probe tip constraint structure 4.

[0072] A probe launching tube 5 with alignment function is installed inside the probe launching tube holder 6, with a driving coil 16 for launching probes and a time division multiplexing coil 17 for measuring rebound speed and recovering probes 7 wound thereon.

[0073] The launch port of the probe launching tube 5 with alignment function is preferably a horn-shaped probe attraction port 18.

[0074] ​​The probe automatic alignment filling device is used as a probe launching and recovering system of the rebound tonometer, generally adopts an electromagnetic coil driving mode, and the automatic alignment of the probe also adopts a filling electromagnetic coil driving mode. The driving coil 16 is used for generating a magnetic field when current passes through the driving coil 16 and pushing the magnetized probe 7 forward to pop out. The function of the time division multiplexing coil 17 is divided into two stages: one is to detect the rebound movement of the probe 7 after hitting the cornea, and the rebound speed is measured through electromagnetic induction principle; the other is to switch to a recovery mode of a large current, and the probe 7 is recovered to the launching point (including recovering the probe after hitting and rebounding, and also including actively sucking the new probe into the probe launching point).

[0075] In the application, the waste packaging plate storage cabin is preferably provided with two (a first waste packaging plate storage cabin 13 and a second waste packaging plate storage cabin 14) and is located below the probe conveying roller 2, and is used for storing the waste probe blister packaging plate 1 after the probe 7 is taken out.

[0076] The working principle of the application is as follows:

[0077] The probe blister packaging plate 1 is clamped between a pair of probe conveying rollers 2, the probe blister packaging plate 1 is fixed by the positioning spike 12 on the probe conveying roller 2 through the packaging plate opening structure 11, the probe conveying roller 2 is driven to rotate by the stepping motor of the probe conveying roller 2, and the two layers of thin packaging sheets of the probe blister packaging plate 1 are torn and unfolded, the probe 7 in the probe blister 10 is exposed, at this time, the magnetic attraction device 3 is electrified and the probe 7 is attracted, the probe 7 attracted is constrained by the probe tail end constraint structure 4, the tail end of the probe 7 is lifted and waits to be filled into the probe launching tube 5 with alignment function. The probe launching tube 5 with alignment function is driven by the linear motor 15 and has only one axial degree of freedom, when the probe launching tube 5 with alignment function moves close to the tail end of the probe 7, the probe launching tube 5 with alignment function starts the attraction mode, at the same time, the electromagnet is de-energized, the probe 7 freely falls due to gravity and is automatically filled into the probe launching tube 5 due to the attraction of the probe launching tube 5 with alignment function, finally, the linear motor can continue to drive the probe launching tube 5 with alignment function to move forward to the launching end of the rebound tonometer, at the same time, the probe launching tube 5 with alignment function switches to the launching mode and is ready to launch the probe 7.

[0078] On the other hand, the application also provides a probe automatic alignment filling method based on the above-mentioned automatic probe replacement device for the rebound tonometer, comprising the following steps:

[0079] Step one: the probe launching tube fixer 6 retreats

[0080] When the rebound tonometer emits a probe, first, the drive coil 16: the current is turned on to eject the previous used probe. Then, the probe launching tube holder 6 retreats from the current launching position by a distance of one probe length, as shown in Figure 7 Step 1, so as to provide sufficient space for the new probe 7 to be filled to be adsorbed by the electromagnet above. The retreat of the probe launching tube holder 6 is driven by the linear motor 15.

[0081] Step 2: actively suck in the new probe. The probe launching tube holder 6 moves forward to the position shown in Figure 7 Step 2, which requires the tail of the probe 7 to fully extend into the probe adsorption inlet 18 and partially extend into the inside of the time-division multiplexing coil 17. Therefore, the horn-shaped design of the probe adsorption inlet 18 can make the tail of the probe 7 extend into the inside of the time-division multiplexing coil 17 as much as possible. At this time, the time-division multiplexing coil 17 is turned on with current, while the electromagnet stops current, so as to fill the probe 7 into the probe launching tube 5 with alignment function. The current of the time-division multiplexing coil 17 is sufficient to fully suck the probe 7 into the inside of the probe launching tube 5 with alignment function, so that the probe 7 is at the launching point. The process of moving the probe launching tube holder 6 forward to the position shown in Figure 7 Step 2 is driven by the linear motor 15.

[0082] Step 3: the probe launching tube holder 6 moves forward and prepares to launch. After the probe 7 is filled, the probe launching tube holder 6 moves forward to the position shown in Figure 7 Step 3, at which time the time-division multiplexing coil 17 stops current and switches to inductive mode, and the drive coil 16 is turned on with launch current to launch the new probe, and then the time-division multiplexing coil 17 detects the rebound speed of the probe to complete one measurement of intraocular pressure.

[0083] The above is only the preferred specific embodiment of the present application. However, the protection scope of the present application is not limited to this; any person skilled in the art within the technical scope disclosed by the present application; according to the technical solution and improvement concept of the present application, equivalent replacement or change; should be covered in the protection scope of the present application.
