Description

Technical Field

[0001] This utility model relates to the field of lactation care device technology, specifically to a dual-purpose reusable sterile lactation probe. Background Technology

[0002] Blocked milk ducts during lactation are a common clinical nursing problem. Milk stasis not only causes breast engorgement and nipple redness and swelling in postpartum women, but if not cleared in time, it can also easily induce acute mastitis, seriously affecting the smooth progress of breastfeeding. Currently, there are no special probes designed specifically for clearing milk ducts in clinical practice. Most breast milk ducts are cleared by professionals using nursing techniques, which relies entirely on the clinical experience of medical staff. Ordinary medical needles are used to clear milk ducts, which also rely on the clinical experience of medical staff. These instruments are not differentiated by specifications and are mostly designed with a single diameter, which cannot adapt to the individual differences in the thickness of different postpartum women's milk ducts. At the same time, there are some existing technologies related to milk duct clearing, such as the bidirectional milk-clearing stick disclosed in the existing patent technology (patent number: TWM522725U) and the milk-clearing glove disclosed in the existing patent technology (patent number: TWM462601U). However, the above-mentioned technologies or products still have room for improvement in meeting the clinical needs of precise, efficient and safe milk clearing. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-purpose, reusable, sterile lactation probe that can be used for lactation procedures, meeting diverse clinical needs, and offering high efficiency in removing blockages while being easy to operate.

[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: a dual-purpose reusable sterile lactation probe, including a needle hub, a second needle body connected to the needle hub, and a first needle body also connected to the needle hub. The end of the first needle body away from the needle hub is a blunted first needle tip, and the end of the second needle body away from the needle hub is a sharpened second needle tip. Graduation lines are provided along the axial direction on the outer wall of the first needle body. This utility model achieves lactation unblocking operations through the second needle body and the second needle body connected by the needle hub. The blunted first needle tip of the first needle body is used to safely unblock the mammary ducts, avoiding damage to the mammary duct mucosa. The sharpened second needle tip of the second needle body is used to pierce the small white spot or scab at the nipple opening to break the skin and unblock the duct. No instrument replacement is required, thus improving the efficiency of lactation unblocking operations. Simultaneously, the axially arranged graduation lines on the outer wall of the first needle body allow the operator to control the insertion depth of the needle body, avoiding damage to breast tissue caused by excessive insertion, and improving operational accuracy and safety.

[0005] According to one embodiment of this utility model, the needle hub and the first needle body are detachably assembled, and the needle hub and the second needle body are detachably assembled. Through the flexible disassembly and replacement of the first and second needle bodies, the entire assembly does not need to be scrapped if a single component is damaged, effectively reducing the cost of use. More importantly, different specifications of the first and second needle bodies can be matched according to the clinical needs of lactation, adapting to the individual differences in the thickness of the mammary ducts of different patients, improving clinical adaptability. Furthermore, the detachable structure facilitates comprehensive cleaning and high-temperature sterilization of the needle hub, the first needle body, and the second needle body.

[0006] According to one embodiment of the present invention, the outer wall of the first needle body is provided with annular marking rings spaced along its axial direction. Each marking ring is distinguished by a different color, which can form a dual indication with the scale line. The color marking is more intuitive and eye-catching, which can help the operator quickly judge the insertion depth of the first needle body and avoid damage to the mammary ducts due to improper control caused by visual errors.

[0007] According to one embodiment of the present invention, the needle holder has a second needle hole for installing the second needle body, which is used to realize the positioning and assembly of the second needle body and the needle holder, and to ensure the coaxiality of the second needle body after assembly.

[0008] According to one embodiment of the present invention, the needle holder has a first needle hole for installing the first needle body, which is used to realize the positioning and assembly of the first needle body and the needle holder, and to ensure the coaxiality of the first needle body after assembly.

[0009] According to one embodiment of the present invention, a first through hole is provided on the side of the needle holder, and the first through hole is connected to a first needle hole on the needle holder; a third needle hole is provided along the axial direction of the first needle body, penetrating both ends of the first needle body. When the first needle body is connected to the needle holder, the third needle hole is connected to the first through hole, thus forming a through-type air passage structure. With the help of external force to form negative pressure, the small white dots blocking the nipple can be adsorbed and removed without the need for additional tools.

[0010] According to one embodiment of this utility model, a pressing sleeve for sealing the first through hole is sleeved on the outside of the needle hub. When the pressing sleeve is deformed under pressure, it can expel the gas inside the third needle hole and the first through hole. The pressing sleeve is an integrally molded structure of elastic material. The pressing part is formed at the position opposite to the first through hole. The pressing sleeve seals the first through hole, and the pressing sleeve can be deformed under external force and elastically restored after the external force is removed. When the pressing part is deformed under pressure, some of the gas inside the third needle hole and the first through hole is discharged through the first through hole. In this way, during the lactation process, the operator first presses to expel some of the gas inside the third needle hole and the first through hole to carry out the lactation operation. If the operator finds a small white spot blocking the mammary duct at the nipple, he can release the pressing sleeve to allow the end of the first needle body to absorb the small white spot for easy removal.

[0011] According to one embodiment of the present invention, the needle holder is a rotating structure, which is convenient to adapt to the operator's hand grip posture, improve grip comfort and control during operation, and the rotating structure facilitates cleaning and high-temperature sterilization.

[0012] According to one embodiment of the present invention, the first needle tip at the end of the first needle body away from the needle hub is an elliptical blunt structure. Compared with a sharp structure, it can reduce the contact pressure with the mammary duct mucosa, and can effectively avoid scratching or puncturing the mammary duct tissue during insertion and unblocking, thereby improving the safety of the lactation unblocking operation.

[0013] According to one embodiment of this utility model, the needle holder surface is provided with a knurled surface. The knurled surface has a mesh knurled structure, a straight knurled structure, or a diagonal knurled structure, and the knurled pattern is evenly and densely distributed to increase the friction of the operator's hand when holding it, and to avoid slipping and dropping the hand due to sweaty hands or force during the lactation procedure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a double needle structure, with a blunt tip for safely unblocking the mammary ducts and a pointed tip for piercing small white spots, eliminating the need to replace instruments and improving the efficiency of the lactation procedure. Furthermore, the first needle body is equipped with a scale line and a colored ring mark to form a dual depth indicator, which, together with the elliptical blunt needle, controls the insertion depth and avoids damage to the mammary tissue. In addition, the needle hub and needle body are detachable, thus eliminating cleaning dead corners, supporting high-temperature sterilization and reuse, and allowing individual replacement of damaged parts, significantly reducing the cost of use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1:

[0031] As shown in the attached figure Figure 1 - Appendix Figure 6 As shown, a dual-purpose reusable sterile lactation probe includes a needle hub 10, a second needle body 30 connected to the needle hub 10, and a first needle body 20 connected to the needle hub 10. The end of the first needle body 20 away from the needle hub 10 is a blunted first needle tip 21, and the end of the second needle body 30 away from the needle hub 10 is a sharpened second needle tip. Scale lines 23 are provided on the outer wall of the first needle body 20 along its axial direction. This invention utilizes a second needle body 30 and a first needle body 20 connected by a needle hub 10 to perform a lactation procedure. The blunted first needle tip 21 of the first needle body 20 is used to safely unblock the mammary ducts and avoid damage to the mammary duct mucosa. The sharpened second needle tip of the second needle body 30 is used to pierce the small white spot or scab at the nipple opening to break the skin and unblock the duct. This eliminates the need to change instruments, thereby improving the efficiency of the lactation procedure. At the same time, the graduation line 23 axially set on the outer wall of the first needle body 20 allows the operator to control the insertion depth of the needle body, avoiding damage to the mammary tissue caused by excessive insertion, and improving the accuracy and safety of the operation.

[0032] The needle hub 10 and the first needle body 20 are detachable, and the needle hub 10 and the second needle body 30 are detachable. Through the flexible disassembly and replacement of the first needle body 20 and the second needle body 30, the entire unit does not need to be scrapped if a single component is damaged, which effectively reduces the cost of use. More importantly, different specifications of the first needle body 20 and the second needle body 30 can be matched according to the clinical needs of lactation, adapting to the individual differences in the thickness of the mammary ducts of different patients, improving clinical adaptability. Furthermore, the detachable structure facilitates the comprehensive cleaning and high-temperature sterilization of the needle hub 10 and the first needle body 20 and the second needle body 30.

[0033] See appendix Figure 2 As shown, the outer wall of the first needle body 20 is provided with annular marking rings 22 spaced along its axial direction. Each marking ring 22 is distinguished by a different color, which can form a dual indication with the scale line 23. The color marking is more intuitive and eye-catching, which can help the operator quickly judge the insertion depth of the first needle body 20 and avoid damage to the mammary ducts due to improper control caused by visual errors.

[0034] See appendix Figure 8 As shown, the needle holder 10 has a second needle hole 17 for installing the second needle body 30, which is used to realize the positioning and assembly of the second needle body 30 and the needle holder 10, and to ensure the coaxiality of the second needle body 30 after assembly.

[0035] See appendix Figure 8 As shown, the needle holder 10 has a first needle hole 16 for installing the first needle body 20, which is used to realize the positioning and assembly of the first needle body 20 and the needle holder 10, and to ensure the coaxiality of the first needle body 20 after assembly.

[0036] See appendix Figure 7 - Appendix Figure 9 As shown, a first through hole 15 is provided on the side of the needle holder 10, and the first through hole 15 is connected to the first needle hole 16 on the needle holder 10; the first needle body 20 is provided with a third needle hole 24 through both ends along its axial direction. When the first needle body 20 is connected to the needle holder 10, the third needle hole 24 is connected to the first through hole 15, thus forming a through air passage structure. With the help of external force to form negative pressure, the small white dots blocking the nipple can be adsorbed and removed without additional tools.

[0037] The needle holder 10 is fitted with a pressing sleeve 50 for sealing the first through hole 15. When the pressing sleeve 50 is pressed and deformed, the gas inside the third needle hole 24 and the first through hole 15 can be discharged. The pressing sleeve 50 is an integrally molded structure of elastic material. The pressing part is formed at the position opposite to the first through hole 15. The pressing sleeve 50 seals the first through hole 15, and the pressing sleeve 50 can be deformed under external force and elastically restored after the external force is removed. When the pressing part 51 is pressed and deformed, some of the gas inside the third needle hole 24 and the first through hole 15 is discharged through the first through hole 15. In this way, during the lactation process, the operator first presses to discharge some of the gas inside the third needle hole 24 and the first through hole 15 to carry out the lactation operation. If the operator finds a small white spot blocking the mammary duct at the nipple, he can release the pressing sleeve 50 so that the end of the first needle body 20 can absorb the small white spot and easily remove it.

[0038] It should be noted that the specific meaning of the white spots described in this case is as follows: White spots mostly form at the opening of the mammary ducts on the nipple. They are "plugs" formed by the concentration and coagulation of fat, protein and other components in milk, or by the proliferation of the stratum corneum of the nipple epidermis blocking the duct opening. They appear as small white or light yellow granules on the nipple and have a hard texture.

[0039] The needle holder 10 has a rotating structure to accommodate the operator's hand grip posture, improve grip comfort and control during operation, and the rotating structure facilitates cleaning and high-temperature sterilization.

[0040] The first needle tip 21 at the end of the first needle body 20 away from the needle hub 10 has an elliptical blunt structure. Compared with a sharp structure, it can reduce the contact pressure with the mammary duct mucosa, and can effectively avoid scratching or puncturing the mammary duct tissue during insertion and unblocking, thus improving the safety of the lactation unblocking operation.

[0041] The needle holder 10 has a knurled surface 11. The knurled surface 11 has a mesh knurled structure, a straight knurled structure, or a diagonal knurled structure, and the knurled pattern of the knurled surface 11 is evenly and densely distributed to increase the friction of the operator's hand when holding it, and to avoid slipping and dropping the hand due to sweaty hands or force during the lactation procedure.

[0042] Example 2:

[0043] The assembly methods of the needle holder 10 with the first needle body 20 and the second needle body 30 include, but are not limited to, threaded connection, snap-fit ​​connection, plug-in connection, magnetic connection and other detachable connection methods.

[0044] For the connection method, please refer to the appendix. Figure 4 As shown, the needle holder 10 has an assembly hole for assembling the first needle body 20 and the second needle body 30. The inner surface of the assembly hole has a first hole surface 12, which is a polygonal structure containing multiple planes. The assembly part of the first needle body 20 and the second needle body 30 that mates with the assembly hole is set as a polygonal structure that is adapted to the first hole surface 12.

[0045] For the connection method, please refer to the appendix. Figure 5 As shown, the needle holder 10 has an assembly hole for assembling the first needle body 20 and the second needle body 30. The inner surface of the assembly hole forms a second hole surface 13, which is a smooth circular transition surface. Correspondingly, the assembly part of the first needle body 20 and the second needle body 30 that mates with the assembly hole is set as a circular structure that matches the second hole surface 13. Of course, it is not limited to a circular shape or an elliptical shape.

[0046] Example 3:

[0047] In this embodiment, the diameters of the first needle body 20 and the second needle body 30 include, but are not limited to, the following specifications: 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1mm, with 0.3mm, 0.4mm, and 0.8mm being preferred as commonly used specifications.

[0048] Example 4:

[0049] In this embodiment, see Appendix Figure 4 As shown, a third needle body 40 can also be fitted into the first needle hole 16 or the second needle hole 17. The third needle body 40 is made of a flexible material with a relatively hard texture, which forms a material compatibility difference with the first needle body 20 and the second needle body 30, which are made of steel needle material, and provides different usage options for operation.

[0050] Example 5:

[0051] In this embodiment, see Appendix Figure 6 As shown, the side of the needle holder 10 has a threaded hole that communicates with the first needle hole 16. The threaded hole is perpendicular to the axis of the first needle hole 16, and a screw 14 is provided in the threaded hole. The screw 14 is preferably an internal hexagon screw.

[0052] Alternatively, the side of the needle holder 10 may have a threaded hole communicating with the second needle hole 17. The threaded hole is perpendicular to the axis of the second needle hole 17, and a screw 14 is provided in the threaded hole. The screw 14 is preferably an internal hexagon screw.

[0053] The assembled first needle body 20 or second needle body 30 is vertically locked by tightening screw 14 to prevent the needle body from loosening, shifting or rotating circumferentially during operation.

[0054] Example 6:

[0055] See appendix Figure 10 As shown, this is a needle holder 60 used with the dual-purpose reusable sterile lactation probe of this utility model. The needle holder 60 includes a first plate 61, and a second plate 65 connected to one end of the first plate 61. The first plate 61 and the second plate 65 have an included angle, and their ends are connected. The other ends are connected by a bent first connecting plate 62. A second connecting plate 64 is also provided between the opposing surfaces of the two plates to connect their inner surfaces. The surface of the first connecting plate 62 is evenly distributed with limiting holes 63 penetrating the surface of the first connecting plate 62. The second connecting plate 64 has openings that correspond to the limiting holes 63. 3. The number and position of the corresponding fine holes allow the first needle body 20, the second needle body 30, or the third needle body 40 at one end of the needle holder 10 to pass through the limiting hole 63 and the fine holes, so that the needle holder 10 can be placed on the needle holder 60. The needle holder 60 can hold multiple dual-purpose reusable sterile lactation probes. The diameter of the first needle body 20 or the second needle body 30 connected to each lactation probe is different. In this way, the needle holder 60 can hold multiple lactation probes with different diameter needle bodies at the same time, which can realize the classification and neat placement of probes of different specifications, making it convenient for operators to quickly take out the appropriate needle body and improve the efficiency of clinical operation.

[0056] Example 7:

[0057] See appendix Figure 11 As shown, the needle holder 70 is used in conjunction with the dual-purpose reusable sterile lactation probe of this utility model. When the dual-purpose reusable sterile lactation probe is not in use, it should be placed in the needle holder 70 for storage. Note that the dual-purpose reusable sterile lactation probe needs to be sterilized before being placed in the needle holder.

[0058] The needle holder 70 includes a box body, the interior of which is divided into multiple placement spaces by multiple partitions 72. The partitions 72 have slots 73, and the slots 73 on the multiple partitions 73 are positioned correspondingly to facilitate personnel to take out the dual-purpose reusable sterile lactation probe. The box body has a lid 71 that fits on top of it, and the two are assembled by sliding.
