Description

TECHNICAL FIELD

[0001] The application relates to a freezing carrier rod, in particular to a vitrification freezing carrier rod. BACKGROUND

[0002] The most widely used vitrification freezing carrier rod on the market is a semi-closed structure, which is usually composed of a carrier sheet, a handle and a sleeve, wherein the carrier sheet and the handle are usually bonded by medical adhesive. With more and more patients choosing to place embryos in a liquid nitrogen environment at-196 DEG C for long-term freezing, some embryos will be frozen for more than 10 years. This is extremely strict for the material requirements of the vitrification freezing carrier rod, and the selection of low-temperature resistant plastic materials and adhesives becomes the core factor to be considered for the product. For plastic materials, there are medical materials on the market that have been verified to be resistant to low temperature, but for adhesives, there is no medical adhesive on the market that can claim to be resistant to-196 DEG C environment for a long time. The semi-closed freezing carrier rod product currently in use also does not guarantee that it can withstand the liquid nitrogen environment for more than 10 years. With the popularization of embryo freezing technology, the number and freezing time of embryo freezing will also increase year by year. At present, some embryos will be frozen in liquid nitrogen environment for more than 10 years or even decades, which is more stringent for the requirements of the bonding adhesive. The bonding design of the handle and the carrier sheet will cause the bonding of the adhesive to fail due to the embrittlement effect of long-term liquid nitrogen freezing, resulting in the loss of embryos on the carrier sheet.

[0039] In the following, only some exemplary embodiments are described briefly. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0040] Figures 1-3 A structural diagram of a vitrification frozen slide rod 100 is shown according to an embodiment of the present application. As shown in the figure, the frozen slide rod 100 can include: Figures 1-3

[0041] a handle 110;

[0042] a connecting block 120, which is arranged on the handle 110;

[0043] a slide glass 130, which has a clamping hole 131 adapted to the connecting block 120, and when the slide glass 130 is arranged on the handle 110, the connecting block 120 passes through the clamping hole 131.

[0044] ​In the embodiment, in the initial state, the handle 110 is not in contact with the slide 130. When installing, the clamping hole 131 on the slide 130 is matched with the connecting block 120. After the connecting block 120 passes through the clamping hole 131, the slide 130 is pulled, the connecting block 120 slides along the clamping hole 131, and then the slide 130 is clamped into the gap of the connecting block 120, and then the handle 110 is preliminarily physically connected with the slide 130.

[0045] By setting the clamping hole 131 matched with the connecting block 120 on the slide 130, when the slide 130 is installed on the handle 110, the connecting block 120 and the clamping hole 131 are preliminarily connected, when the slide 130 is connected with the handle 110, the slide 130 is clamped into the gap of the connecting block 120, and then the handle 110 is preliminarily physically connected with the slide 130, which avoids the situation that the handle 110 and the slide 130 are separated due to the invalidation of the glue caused by liquid nitrogen, provides double insurance for the connection between the slide 130 and the handle 110, and reduces the risk that the slide 130 is separated from the handle 110 due to the invalidation of the connecting glue caused by long-term liquid nitrogen freezing, thereby causing the loss of embryos.

[0046] As shown in FIG. 1, Figures 2-3 in an embodiment,

[0047] The cross section of the connecting block 120 is an inverted stepped structure or an inverted "L" shaped structure.

[0048] In the embodiment, the connecting block 120 is set as an inverted stepped structure or an L-shaped structure, so that a gap is formed between the connecting block 120 and the handle 110. When the slide 130 is connected with the handle 110, the connecting block 120 passes through the clamping hole 131 first, and then the slide 130 is pulled, so that part of the slide 130 is located in the gap between the connecting block 120 and the handle 110.

[0049] Further, the gap between the connecting block 120 and the handle 110 is the same as the thickness of the slide 130. When the slide 130 is installed on the handle 110, the two sides of the slide 130 are respectively attached to the connecting block 120 and the handle 110, thereby increasing the friction force of the two sides of the slide 130 located inside the handle 110 when the slide 130 is installed, so that the connection between the slide 130 and the handle 110 is more stable.

[0050] As shown in FIG. 1, Figure 3 in an embodiment,

[0051] The handle 110 has a notch 111 at the connection with the slide 130, and the connecting block 120 is located in the notch 111.

[0052] In this embodiment, the end of the handle 110 connected to the carrier 130 has a notch 111. When the carrier 130 is connected to the handle 110, the carrier 130 is first placed into the notch 111 so that the center line of the carrier 130 and the handle 110 coincides. When the carrier 130 abuts against the innermost side of the notch 111, the locking hole 131 on the carrier 130 corresponds to the position of the connecting protrusion 120. The carrier 130 is pressed down so that the connecting protrusion 120 passes through the locking hole 131 and the carrier 130 is pulled outward. Thus, part of the carrier 130 is located between the connecting protrusion 120 and the handle 110, thereby completing the connection between the carrier 130 and the handle 110. The design of the notch 111 facilitates the positioning of the carrier 130 when it is installed with the handle 110.

[0053] Furthermore, the gap between the outer side of the connecting protrusion 120 and the top wall of the notch 111 is greater than the thickness of the carrier 130, so that the carrier 130 can be inserted into the notch 111 from above the connecting protrusion 120, thereby allowing the carrier 130 to abut against the deepest part of the notch 111.

[0054] Furthermore, by passing the connecting protrusion 120 through the card hole 131, the carrier 130 can be positioned by the connecting protrusion 120, thereby facilitating the alignment of the center line of the carrier 130 with the center of the handle 110.

[0055] like Figures 2-3 As shown, in one embodiment, it further includes:

[0056] The adhesive layer 140 is positioned at the notch 111 after the connecting protrusion 120 passes through the locking hole 131.

[0057] In this embodiment, the adhesive layer 140 is glue. When the connecting protrusion 120 passes through the locking hole 131 and the carrier 130 is pulled, the carrier 130 is engaged between the handle 110 and the connecting protrusion 120. Then, the glue is applied into the notch 111 to fix the connection between the carrier 130 and the handle 110. After the glue in the notch 111 solidifies, the adhesive layer 140 is formed.

[0058] like Figure 1 As shown, in one embodiment, it further includes:

[0059] Sleeve 150 is detachably mounted on handle 110.

[0060] In this embodiment, the sleeve 150 is detachably mounted on the handle 110. When the sleeve 150 is mounted on the handle 110, the carrier 130 is located inside the sleeve 150, thereby protecting the carrier 130 when not in use.

[0061] like Figures 1-3As shown, in one embodiment,

[0062] The handle 110 has a protrusion 112 that fits into the interface of the sleeve 150.

[0063] In this embodiment, the handle 110 is provided with a protrusion 112, and the sleeve 150 is sleeved on the protrusion 112 at the interface between the handle 110 and the sleeve 150.

[0064] Furthermore, the diameter of the end of the protrusion 112 facing the sleeve 150 is smaller than the diameter of the end of the protrusion 112 away from the sleeve 150.

[0065] Understandably, the cross-section of the protrusion 112 is an isosceles trapezoidal structure. The sleeve 150 is fitted onto the end of the protrusion 112 with the smallest diameter. The sleeve 150 is fixed to the protrusion 112 by gradually increasing the diameter of the protrusion 112, which makes it easier to fix the sleeve 150 to the handle 110.

[0066] like Figures 2-3 As shown, in one embodiment,

[0067] When the carrier 130 is placed on the handle 110, the center line of the carrier 130 coincides with the center line of the handle 110.

[0068] In this embodiment, when the carrier 130 is installed on the handle 110, the center line of the carrier 130 coincides with the center line of the handle 110, which facilitates the use of the carrier 130 and the handle 110. At the same time, the coincidence of the center line of the carrier 130 with the center line of the handle 110 also facilitates the installation of the carrier 130 on the handle 110, simplifying the installation process of the carrier 130 on the handle 110.

[0069] like Figure 2 As shown, in one embodiment,

[0070] One end of the 131 slot is arched.

[0071] In this embodiment, the end of the card hole 131 facing the inside of the notch 111 is set in the shape of an arch, and the other end is rectangular. The shape of one end of the connecting protrusion 120 is adapted to the shape of the card hole 131, so as to facilitate the positioning of the connecting protrusion 120 when it passes through the card hole 131.

[0072] Furthermore, one end of the card hole 131 can also be in the shape of a triangle or other irregular shapes, so as to facilitate the positioning between the carrier 130 and the connecting protrusion 120.
