Description

Technical Field

[0001] This application relates to the field of newborn nose strip cutter technology, and more particularly to a newborn nose strip cutter. Background Technology

[0002] When newborns undergo non-invasive mechanical ventilation, nasal plugs or masks are needed to ensure close contact with the nose to allow air to enter the infant's body smoothly. However, because newborns' skin is very delicate, prolonged use may cause damage to the nasal skin and mucous membranes. To protect the newborn's nasal skin, healthcare professionals often choose to use adhesive artificial skin (such as hydrocolloid dressings) to reduce the risk of skin damage.

[0003] To improve the adaptability and comfort of dressings and thus more effectively protect the nasal skin of newborns, medical staff will take measures such as cutting the dressing into "T" or "H" shapes and punching holes in the nostrils to better fit the nasal structure of newborns.

[0004] However, hydrocolloid dressings require manual cutting before use, a process that is not only time-consuming and labor-intensive, but also often results in variations in size and shape, which may affect the protective effect. For example, patent CN111086056A discloses a neonatal nasal strip forming device, which uses annular grooves to cut hydrocolloid dressings to the required size. However, because neonatal nasal sizes vary, the fixed-size annular grooves cannot adjust the size of the nasal strips to suit different neonatal sizes, resulting in poor flexibility.

[0034] The utility model provides a new type of newborn nose paste 400 cutting device as shown in Figures 1 to 3 The utility model provides a new type of newborn nose paste 400 cutting device as shown in

[0035] The utility model discloses a new type of newborn nose paste 400 cutting device mainly includes: alar part 410, nose column part 420 and philtrum part 430, preferably, alar part 410, nose column part 420 and philtrum part 430 form "H" structure.

[0036] The utility model discloses a new type of newborn nose paste 400 cutting device mainly includes: alar part 410, nose column part 420 and philtrum part 430, preferably, alar part 410, nose column part 420 and philtrum part 430 form "H" structure.

[0037] The bottom plate 100 is used to place the dressing 500 (the dressing 500 is placed on the surface of the bottom plate 100 facing the pressing plate 200), the pressing plate 200 is parallel to the bottom plate 100, and the pressing plate 200 is driven to move towards the bottom plate 100. Preferably, a scissors handle is also included, by which the pressing plate 200 can be moved towards the bottom plate 100. The scissors handle is a force-saving lever structure. The cutting unit 300 is located between the bottom plate 100 and the pressing plate 200, and is used to cut the dressing 500 on the surgical bottom plate 100. In actual use, the cutting unit 300 is driven by the pressing plate 200 to move towards the bottom plate 100 to cut the dressing 500 on the bottom plate 100 into the required shape.

[0038] The bottom plate 100 has an X-axis direction and a Y-axis direction perpendicular to each other, both of which are parallel to the bottom plate 100. The cutting unit 300 includes a nasal ala cutter 310, a columella nasi cutter 320, and a philtrum cutter 330 arranged at intervals along the Y-axis direction on the pressing plate 200, and the nasal ala cutter 310 and the philtrum cutter 330 are slidingly arranged along the Y-axis direction. The distance between the columella nasi cutter 320 and the nasal ala cutter 310 is the length a of the tip of the nose, and the distance between the philtrum cutter 330 and the columella nasi cutter 320 is the length c of the philtrum.

[0039] Specifically, the bottom plate 100 and the pressing plate 200 can be made of materials with high hardness such as plastic and stainless steel, which can reduce the deviation during cutting and reduce the error of the size of the nose paste. The cutting unit 300 can be made of stainless steel, ceramic, etc., and the end thereof facing the bottom plate 100 is a cutting edge portion, which can cut off the dressing 500.

[0040] In actual use, the length a of the tip of the nose of the newborn nose paste 400 can be changed by adjusting the distance between the columella nasi cutter 320 and the nasal ala cutter 310, and the length c of the philtrum of the newborn nose paste 400 can be changed by adjusting the distance between the philtrum cutter 330 and the columella nasi cutter 320. After measuring the nasal data of the newborn, the medical staff can adjust the distance between the columella nasi cutter 320 and the nasal ala cutter 310, and the distance between the philtrum cutter 330 and the columella nasi cutter 320, so as to change the size of the nose paste.

[0041] The hydrocolloid dressing 500 needs to be manually cut before use, which not only consumes time and effort, but also often has differences in size and shape, which may affect the protection effect. For example, the patent with publication number CN111086056A discloses a newborn special nose paste former, which cuts the hydrocolloid dressing 500 into the required size and size by setting an annular groove, but since the sizes of the noses of newborns are different, the fixed specification of the annular groove cannot be adjusted according to the sizes of different newborns, and the flexibility is poor.

[0042] The utility model discloses a nose wing cutting knife 310, a columella nasi cutting knife 320 and a philtrum cutting knife 330 are set, and when cutting the dressing 500, the distance between the columella nasi cutting knife 320 and the nose wing cutting knife 310 and the distance between the philtrum cutting knife 330 and the columella nasi cutting knife 320 can be adjusted according to the length a of the nose tip and nose root of the newborn and the length c of the philtrum respectively, so that the size of the required nose sticker is obtained, and the flexibility is high.

[0043] In some embodiments, as shown in Figures 2 to 3 The shape of the nose wing cutting knife 310 is arc-shaped, and the centripetal direction of the nose wing cutting knife 310 is towards the columella nasi cutting knife 320.

[0044] The shape of the philtrum cutting knife 330 is linear, and the philtrum cutting knife 330 is arranged along the X-axis direction.

[0045] Preferably, the shape of the nose wing cutting knife 310 can be V-shaped, which is beneficial to better cover the nose of the newborn. The shape of the philtrum cutting knife 330 is linear, so that when the nose sticker is pasted in the philtrum, the edge of the nose sticker close to the mouth is linear, avoiding shielding the mouth.

[0046] In some embodiments, as shown in Figures 2 to 3 The columella nasi cutting knife 320 comprises two half-arc-shaped cutting knives 321, the centripetal directions of the two half-arc-shaped cutting knives 321 are oppositely arranged, and the centripetal directions of the two half-arc-shaped cutting knives 321 are along the X-axis direction. The distance between the two half-arc-shaped cutting knives 321 is the length b of the columella nasi.

[0047] Preferably, the shape of the half-arc-shaped cutting knife 321 is "Fang" character-shaped, the upper edge and the lower edge of which are linear, so that when the nose sticker is pasted on the nose, the lower edge of the nose sticker on the nose tip and the upper edge of the philtrum are linear, avoiding shielding the nostrils.

[0048] The length of the nose wing cutting knife 310, the philtrum cutting knife 330 and the two half-arc-shaped cutting knives 321 along the X-axis direction is greater than the length of the dressing 500 along the X-axis direction, so that the dressing 500 can be cut in the Y-axis direction. If the length of the nose sticker in the X-axis direction is too long or too sharp, the medical staff can use scissors to cut or smooth.

[0049] In some embodiments, as shown in Figures 2 to 3 The two half-arc-shaped cutting knives 321 are slidably arranged on the pressing plate 200 along the X-axis direction.

[0050] Specifically, since the sizes of the noses of different newborns are different, the lengths of the nasal alar cutter 310, the philtrum cutter 330, and the two half-arc-shaped cutters 321 in the X-axis direction are equal to the length of the dressing 500 in the X-axis direction in the initial state, and the interval between the two half-arc-shaped cutters 321 in the X-axis direction is preferably the minimum philtrum length c, so as to avoid that the dressing 500 cannot be cut in the Y-axis direction when cutting the nasal patch for a small-size philtrum length c.

[0051] In some embodiments, as shown in Figures 1 to 2 , the newborn nasal patch 400 cutter further comprises a plurality of sliding grooves 210, and the nasal alar cutter 310, the philtrum cutter 330, and the two half-arc-shaped cutters 321 are respectively slidably arranged in the plurality of sliding grooves 210.

[0052] Specifically, the plurality of sliding grooves 210 are arranged along the X-axis direction and the Y-axis direction, and are arranged through the pressing plate 200 along a direction (Z-axis direction, not shown in the figure) perpendicular to the X-axis direction and the Y-axis direction.

[0053] In some embodiments, as shown in Figure 1 , the surface of the pressing plate 200 away from the bottom plate 100 is a visual surface, and a plurality of scales 220 are arranged on the visual surface, and the plurality of scales 220 correspond to the plurality of sliding grooves 210 and are arranged on the visual surface. The scales 220 are used to measure the nasal tip-nasal root length a, the nasal tip-nasal root length a, and the nasal columella length b.

[0054] Specifically, since the sliding grooves 210 are hollow, the nasal alar cutter 310, the philtrum cutter 330, and the two half-arc-shaped cutters 321 located on the back of the visual surface can be directly observed through the sliding grooves 210. At this time, by observing the positions of the scales 220 and the nasal alar cutter 310, the philtrum cutter 330, and the two half-arc-shaped cutters 321, the nasal tip-nasal root length a, the nasal tip-nasal root length a, and the nasal columella length b of the nasal patch can be obtained.

[0055] In some embodiments, as shown in Figures 1 to 2 , the newborn nasal patch 400 cutter further comprises a plurality of hand-dial blocks 340, and the plurality of hand-dial blocks 340 are respectively arranged on the nasal alar cutter 310, the philtrum cutter 330, and the two half-arc-shaped cutters 321, and the plurality of hand-dial blocks 340 are in contact with the visual surface through the corresponding sliding grooves 210.

[0056] Specifically, the part of the hand-dial block 340 located in the sliding groove 210 can be used as a sliding block and is slidably arranged in the sliding groove 210.

[0057] The end of the hand-dial block 340 facing the cutting unit 300 is connected with the nasal alar cutter 310, the philtrum cutter 330, and the two half-arc-shaped cutters 321, respectively.

[0058] The part of the hand dialing block 340 towards the visual surface can act as a pointer for coinciding with the corresponding scale 220 to obtain the positions of the alar nasi cutter 310, the philtrum cutter 330 and the two semi-arc linear cutters 321 respectively, so as to obtain the tip-nose root length a, the tip-nose root length a and the columella nasi length b of the nose patch. The hand dialing block 340 can be used for the medical staff to push by hand, thereby driving the alar nasi cutter 310, the philtrum cutter 330 and the two semi-arc linear cutters 321 to move respectively.

[0059] In some embodiments, as shown in Figure 2 The neonatal nose patch 400 cutter further comprises a lead screw 350, the lead screw 350 is rotationally arranged on the pressing plate 200, and the lead screw 350 is connected with the two semi-arc linear cutters 321.
