Description

Technical Field

[0001] This utility model relates to an ice pop, and more particularly to an ice pop used for cold testing of dental pulp vitality. Background Technology

[0002] Pulp vitality testing is a core method for assessing the health of dental pulp. Cold testing, the most commonly used clinical method for pulp temperature testing, involves placing a cold stimulus below 10°C on the surface of the tooth crown and judging the pulp condition based on the tooth's response to the cold stimulus.

[0003] Currently, homemade popsicles are commonly used for cold testing in clinical practice. However, their production process typically involves simply filling a cylindrical plastic mold with distilled water into an open end, freezing it, and then using it. This method lacks effective sealing during filling, making aseptic operation impossible. It only meets general cleaning requirements but falls short of the aseptic standards used in medical procedures.

[0004] Furthermore, once the end of the homemade popsicle is consumed, the subsequent popsicles are frozen together with the plastic shell and are difficult to separate. It is necessary to wait for the outer layer of the popsicle to melt before it can be pushed, which increases the detection time. Utility Model Content

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Embodiments of this utility model: such as Figures 1-4 As shown, an ice stick for cold testing of dental pulp vitality includes a cylindrical tube 1. Multiple annular protrusions 2 are evenly spaced on the inner wall of the cylindrical tube 1. In this embodiment, two annular protrusions 2 are preferably provided. One end of the cylindrical tube 1 is provided with an end cap 3. The cylindrical tube 1 is filled with sterile distilled water.

[0022] The end of the cylindrical tube 1 furthest from the end cap 3 is a closed end. During production, sterile distilled water is first injected through a dedicated filling channel (not shown in the figure) on the end cap 3. Then, a heat-sealing process is used to fuse and seal the end cap 3, permanently sealing the filling channel and completely encapsulating the distilled water within the cylindrical tube 1. Subsequently, the product undergoes terminal sterilization treatment such as irradiation or ethylene oxide to ensure it reaches a sterile state.

[0023] After the hospital purchases this product, it freezes it in the refrigerator. The sterile distilled water turns into ice pillars. When using it, take it out of the refrigerator, open the end cap 3, and use it. After the end of the ice pillar 8 melts and shortens, break the ice pillar 8 at the position with the annular protrusion 2, squeeze out the ice pillar 8 to the required length, and continue to use it.

[0024] Because multiple annular protrusions 2 are provided on the inner wall of the cylindrical tube 1, multiple annular grooves are formed on the ice column 8 after the sterile distilled water freezes into ice columns. This makes it easy to break the ice column 8 into multiple segments, which facilitates the compression and movement of the ice column 8, solving the problem that the ice column cannot be compressed when frozen together with the outer packaging in the existing technology.

[0025] Specifically, two wing plates 4 are provided on the outer wall of the cylindrical tube 1, and the two wing plates 4 are symmetrically distributed with respect to the axis of the cylindrical tube 1. Preferably, each of the two wing plates 4 is provided with multiple triangular notches 7, and the position of the triangular notches 7 is opposite to the position of the annular boss 2. In this embodiment, each wing plate 4 has two triangular notches 7.

[0026] In this embodiment, the wall thickness of the cylindrical tube 1 is preferably 2mm, and the thickness of the wing plate 4 is preferably 3mm. By setting the wing plate 4, it is convenient for the fingers to apply circumferential rotational force to the cylindrical tube 1, which makes it easy to separate the inner wall of the cylindrical tube 1 from the ice column 8 and prevent them from sticking together and being unable to be squeezed.

[0027] The cylindrical tube 1, the annular boss 2, the end cap 3, and the wing plate 4 are all made of low-density polyethylene (LDPE). This material has excellent flexibility, chemical inertness, low moisture permeability, and can be sterilized by radiation or ethylene oxide. Furthermore, using this material has the advantage of low cost.

[0028] Furthermore, the end cap 3 is a rectangular plate structure, and an annular groove 5 is machined on the outer wall of the end where the cylindrical tube 1 connects to the end cap 3.

[0029] By machining the annular groove 5, the end of the cylindrical tube 1 can be easily torn off by rotating the end cap 3 during use, thus allowing the icicle 8 to leak out. Preferably, the depth of the annular groove 5 is 1 mm, that is, the depth of the annular groove 5 is half the wall thickness of the cylindrical tube 1.

[0030] Preferably, it also includes an insulating outer jacket 6, which is a cylindrical jacket, and the length of the insulating outer jacket 6 is two-thirds of the length of the cylindrical tube 1. The insulating outer jacket 6 is made of insulating cotton.

[0031] An insulating jacket 6 is placed over the cylindrical tube 1, preventing doctors from getting frostbite when holding the tube 1. Furthermore, the insulating jacket 6 slows down the melting of the icicle 8 inside, making the icicle 8 more durable.

[0032] The method of using this utility model is as follows: When using it, take it out of the refrigerator and then insert its tail end into the thermal insulation jacket 6. After inserting it into place, one-third of it is outside the thermal insulation jacket 6. It should be noted that the thermal insulation jacket 6 is a reusable product, while the rest is for single use and should be discarded after use.

[0033] Rotate the end cap 3, and the end of the cylindrical tube 1 breaks off at the position with the annular groove 5, exposing the end of the ice column 8. The dentist holds the product and places the end face of the ice column 8 against the patient's tooth. The tooth surface to be tested is dried with a cotton ball. The dentist holds the product and places the end face of the ice column 8 against the middle of the labial (buccal) surface of the tooth to be tested, near the cervical 1 / 3 area, observing the patient's reaction and recording any pain, sensitivity, or other discomfort. If the patient reacts, or if there is no reaction after 15 seconds of testing, the test can be stopped.

[0034] As the ice column 8 is used, its end will melt. The cylindrical tube 1 will then rotate circumferentially via the wing plate 4, separating it from the ice column 8. The ice column 8 will then be broken off at the location with the triangular notch. It should be noted that although the ice column 8 is broken, the cylindrical tube 1 will not break. The ice column 8 will then be squeezed to expose the desired length for further testing. This process continues until the entire ice column 8 is consumed.

[0035] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
