Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a manual colostrum collector. Background Art

[0002] Colostrum refers to the milk secreted within one week after birth. After birth, the hormone level in the mother's body changes, and the breasts begin to secrete milk. However, there is a gradual change in the quality and quantity of lactation. Generally, the milk within 2 to 3 days after birth is called colostrum, the milk 4 to 10 days after birth is called transitional milk, the milk from 11 days to 9 months after birth is called mature milk, and the milk after 10 months is called late milk. This change in the quality and quantity of breast milk just meets the digestion, absorption and physical needs of newborns.

[0003] Compared with cooked milk, the whey protein content in colostrum is higher. Colostrum contains 5 times more protein than normal milk and can be directly absorbed. In particular, it contains more immunoglobulins, lactoferrin, growth factors, macrophages, neutrophils and lymphocytes than normal milk. These substances have the function of preventing infection and enhancing immunity. Colostrum contains a large amount of growth factors, especially epithelial growth factor, which can promote the growth of epithelial cells in the gastrointestinal tract of newborns, promote the rapid development of epithelial cells in the liver and other tissues, and also participate in regulating the pH value of gastric juice.

[0004] Therefore, colostrum, which is rich in nutrients, can supplement the nutrition needed by newborns, improve resistance and immunity, and promote the growth of newborns. Especially for premature babies, the nutrition of colostrum is particularly important.

[0005] Since the amount of colostrum secreted is small, generally about 30-40 ml a day, some people only have 5-10 ml, or even a few drops. Also, since newborns are not used to sucking nipples when they first start breastfeeding, colostrum needs to be collected first.

[0006] However, it is particularly difficult to collect a small amount of colostrum. The feeding bottle connected to the current ordinary breast pump has a large capacity and is connected with a long tube in the middle. The small amount of colostrum sticks to the various parts of the breast pump during the entire collection process, causing waste, resulting in a small amount of actual collection, and the amount of colostrum subsequently fed to the newborn is also greatly reduced. The actual utilization rate is low, and cleaning the breast pump is very cumbersome.

[0007] Therefore, there is a need for a collector that can conveniently and directly collect colostrum and improve the collection rate and utilization rate. Utility Model Content

[0008] The utility model aims to provide a manual colostrum collector, which can collect colostrum quickly and directly through a negative pressure structure that is easy to operate, and is convenient for subsequent feeding, storage and cleaning.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A manual colostrum collector comprises a cover, a cylinder for containing colostrum and a negative pressure structure, wherein a docking joint is provided at one end of the cylinder, and the cover is detachably connected to the docking joint, and the negative pressure structure comprises a control button, a piston and a transmission assembly, wherein the piston is movably arranged in the cylinder, and the side wall of the piston is in contact with the inner wall of the cylinder, and an adjustment seat is provided at one end of the cylinder away from the docking joint, the control button is arranged on the adjustment seat, and the control button drives the piston to move in the cylinder through the transmission assembly.

[0011] Compared with the prior art, the manual colostrum collector using the above technical solution has the following beneficial effects:

[0012] 1. The manual colostrum collector of the utility model is connected through the cover body and the docking head, and the cover body is fitted on the nipple. The colostrum is extracted from the lactation hole by using the negative pressure principle, and with the displacement of the piston, a small amount of colostrum will be directly collected into the cylinder, so that the colostrum can be collected quickly and directly, thereby increasing the amount of colostrum obtained by the newborn. And only the control button needs to be moved to drive the piston for suction, which is convenient for the mother to operate manually with one hand, and the operation does not need to trouble others, and the other hand can be freed up to take care of the newborn or perform other actions.

[0013] Second, since the joints of the cover body and the cylinder body are relatively independent and separable, the cover body and the cylinder body can be disassembled separately for cleaning operations, so as to facilitate subsequent collection operations.

[0014] Preferably, the transmission assembly includes an adjustment rod and a convex tooth portion, the adjustment rod is connected to the movable body, and the adjustment rod can move in the barrel and the adjustment seat at the same time, the convex tooth portion is arranged on the side wall of the adjustment rod facing the control button, the control button adopts a disc-shaped structure, the control button is connected to the adjustment seat through a rotating shaft, and a plurality of convex tooth structures evenly spaced are arranged on the outer peripheral surface of the control button, and the convex tooth portion is meshed with the control button. Utilizing the gear transmission structure, during the rotation of the control button, the piston will be synchronously displaced to suction, and in actual operation, the parturient only needs to twist the control button with the thumb to operate, which is convenient for quick operation; and because the convex tooth structures on the control button and the convex tooth portion are evenly spaced and slow suction operation is realized, the suction action can be stopped in time when discomfort is felt or the current colostrum has been sucked out.

[0015] Preferably, a stopper block for limiting the state of the movable rod is further included, and a stopper tooth is provided on the side of the stopper block facing the convex tooth portion. The stopper block is movably arranged on the rotating shaft, and the stopper block can be displaced along the length direction of the rotating shaft, and the stopper block is displaced to push the control button away from the convex tooth portion. Since the stopper block cannot rotate at the adjustment seat, the stopper tooth limits the position of the adjustment rod by controlling the stopper block, thereby temporarily fixing the position of the piston and avoiding the problem of accidentally driving the piston when the control button or the adjustment rod is touched by mistake.

[0016] Preferably, a quick docking structure is provided between the cover body and the docking joint, and the quick docking structure includes a locking block, a strip groove and an arc groove. The cover body is provided with a docking tube that can be sleeved on the outside of the docking joint, the locking block is provided on the inner side of the docking tube, the strip groove is provided along the length direction of the docking joint, the strip groove extends to one side of the cover body to form a slot for the locking block to pass through, the arc groove is provided along the outer peripheral surface of the docking joint close to the cylinder body, and the arc groove is connected with the strip groove, and a clamping block made of elastic material is provided in the slot and the arc groove, and the locking block can pass through the slot and the strip groove in turn, and be clamped at the bottom of the arc groove. By utilizing the telescopic characteristics of the elastic material of the clamping block and the matching structure of the strip groove and the arc groove, after the locking block is clamped into the bottom of the arc groove, the docking state cannot be directly released by accidentally pulling the docking tube and the cylinder body; and quick docking can be performed by directly inserting and rotating, which is easy for parturients to directly operate.

[0017] Preferably, a guide tube for guiding the flow of colostrum is provided inside the docking tube, and the guide tube is connected to the inside of the cover body. When the docking tube is connected to the docking head, the guide tube fits the inner wall of the docking head, and the end of the guide tube away from the cover body is located at the junction of the docking head and the inside of the cylinder body. After the colostrum is sucked, it will flow directly into the cylinder body under the guidance of the guide tube, which can effectively prevent the colostrum from flowing into the gap between the docking tube and the docking head, and avoid the waste of colostrum by adhesion, and avoid the problem of accidental dripping of colostrum or contamination of clothes and sheets when the cover body is separated.

[0018] Preferably, it also includes a nipple and a cover, and the nipple and the cover are both provided with a docking tube for connecting the docking joint. The docking joint is respectively connected to the housing, the nipple and the cover to meet the needs of collecting, feeding and storing colostrum, and cooperates with the above-mentioned guide tube structure to realize the transfer operation of colostrum, effectively improving the collection rate and utilization rate of colostrum.

[0019] Preferably, the end of the guide tube away from the cover body is provided with an arc portion, and when the butt joint tube is connected to the butt joint, the arc surface of the arc portion faces the interior of the cylinder. Through the guiding effect of the arc portion, colostrum can flow directly from the interior of the cylinder into the guide tube during subsequent feeding, further improving the utilization rate of colostrum and increasing the amount of colostrum obtained by the newborn.

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 8 The manual colostrum collector shown comprises a cover body 1 , a cylinder body 2 for containing colostrum, a negative pressure structure 3 , a nipple 8 and a sealing cap 9 .

[0031] A docking joint 4 is provided at one end of the cylinder 2 , and an adjustment seat 5 is provided at one end of the cylinder 2 away from the docking joint 4 .

[0032] In this embodiment, the cover body 1 is an arc-shaped cover structure made of elastic silicone. A spherical placement portion 10 is provided on one side of the cover body 1. When the cover body 1 fits against the chest, the placement portion 10 can be used for the nipple to be placed.

[0033] The cover body 1 is detachably connected to the docking joint 4. The connection structure can be a snap-on structure or a threaded docking structure. In the present embodiment, in order to facilitate quick docking, a quick docking structure 6 is provided between the cover body 1 and the docking joint 4. The quick docking structure 6 includes a locking block 60, a strip groove 61 and an arc groove 62.

[0034] The cover body 1 is provided with a docking tube 7 which can be sleeved on the outside of the docking head 4, and a locking block 60 is arranged on the inner side of the docking tube 7. The strip groove 61 is arranged along the length direction of the docking head 4, and the strip groove 61 extends to one side of the cover body 1 to form a slot 63 for the locking block 60 to pass through. The arc groove 62 is arranged along the outer peripheral surface of the docking head 4 close to the cylinder body 2, and the arc groove 62 is connected with the strip groove 61. The slot 63 and the arc groove 62 are both provided with a clamping block 64 of elastic material. The locking block 60 can pass through the slot 63 and the strip groove 61 in sequence, and be clamped at the bottom of the arc groove 62.

[0035] The clamping block 64 can be made of elastic silicone or elastic rubber. In the present embodiment, the clamping block 64 is made of elastic silicone with medium elasticity, and the edges of the clamping block 64 are all arc-shaped structures.

[0036] In order to prevent colostrum from flowing between the docking joint 4 and the docking tube 7 during suction, a guide tube 70 for guiding the flow of colostrum is provided inside the docking tube 7, and the cover body 1 is provided with a through hole. The guide tube 70 is connected to the cover body 1 and the interior of the placement portion 10 at the same time. When the docking tube 7 is connected to the docking joint 4, the guide tube 70 fits against the inner wall of the docking joint 4, and the end of the guide tube 70 away from the cover body 1 is located at the junction of the docking joint 4 and the inside of the cylinder 2.

[0037] When feeding a newborn, in order to prevent colostrum from being retained between the docking head 4 and the cylinder 2, an arcuate portion 71 is provided at the end of the guide tube 70 away from the cover body 1. When the docking tube 7 is connected to the docking head 4, the arc surface of the arcuate portion 71 faces the interior of the cylinder 2.

[0038] Correspondingly, the nipple 8 and the cover 9 are both provided with the above-mentioned butt joint tube 7 with structures such as the guide tube 70 and the locking block 60.

[0039] The negative pressure structure 3 includes a control button 30, a piston 31 and a transmission assembly. The piston 31 is movably arranged in the cylinder 2, and the side wall of the piston 31 is in contact with the inner wall of the cylinder 2. The control button 30 is arranged on the adjustment seat 5, and the control button 30 drives the piston 31 to move in the cylinder 2 through the transmission assembly.

[0040] The specific transmission method can be through a pull-out structure similar to a syringe, or through a pull rope driving a pulley group transmission structure, or can be a gear transmission structure in this embodiment. In this embodiment, in order to facilitate the mother's independent operation, the transmission assembly includes an adjustment rod 32 and a convex tooth portion 33.

[0041] The adjusting rod 32 is connected to the movable body, and the adjusting rod 32 can move in the cylinder 2 and the adjusting seat 5 at the same time. The convex tooth portion 33 is arranged on the side wall of the adjusting rod 32 facing the control button 30. The control button 30 adopts a disc-shaped structure. The control button 30 is connected to the adjusting seat 5 through a rotating shaft 50. A plurality of convex tooth structures evenly spaced are arranged on the outer peripheral surface of the control button 30, and the convex tooth portion 33 is meshed and connected with the control button 30.

[0042] In order to avoid the problem of accidental displacement of the piston 31 due to accidental touch, a blocking block 34 for limiting the state of the movable rod is also included. Figure 6 As shown, the locking block 34 is a special-shaped structure, and a limiting tooth 35 is provided on the side of the locking block 34 facing the convex tooth portion 33. The locking block 34 is movably arranged on the rotating shaft 50, and the locking block 34 can be displaced along the length direction of the rotating shaft 50. The displacement of the locking block 34 pushes the control button 30 away from the convex tooth portion 33.

[0043] The following is the usage of this embodiment:

[0044] First, the cover body 1 and the cylinder body 2 are docked. Hold the cover body 1 with one hand and the cylinder body 2 with the other hand, insert the locking block 60 in the docking tube 7 on one side of the cover body 1 into the slot 63 of the docking head 4, and the elastic clamping block 64 is forced to shrink after contacting the locking block 60, so that the locking block 60 enters the strip groove 61; continue to push and rotate the cover body 1, so that the locking block 60 moves along the strip groove 61, and then the locking block 60 moves along the arc groove 62. After the locking block 60 contacts the clamping block 64 in the arc groove 62, the clamping block 64 is forced to shrink, so that the locking block 60 is smoothly stuck into the bottom of the arc groove 62. At this point, the cover body 1 and the cylinder body 2 are docked and fixed.

[0045] At this time, the cover body 1 can be covered on the nipple of the parturient so that the nipple is located in the placement portion 10. The parturient can hold the cylinder body 2 with one hand and turn the control button 30 with the thumb. Figure 5 As shown in FIG. 1 , when the control button 30 is rotated counterclockwise, the control button 30 and the convex tooth portion 33 are meshed and connected, and the adjustment rod 32 drives the piston 31 to move in the cylinder 2, and negative pressure suction is performed, and colostrum flows into the cylinder 2. After the suction is completed, the positioning block 34 is moved sideways to make the positioning block 34 move along the length direction of the rotating shaft 50, as shown in FIG. Figure 6 As shown, the control button 30 is disengaged from the convex tooth portion 33, and the limiting teeth 35 of the positioning block 34 are meshed and connected with the convex tooth portion 33. Since the positioning block 34 is fixed at the adjustment seat 5 and cannot rotate, the adjustment rod 32 and the piston 31 are synchronously limited to avoid displacement when the control button 30 or the adjustment rod 32 is accidentally touched.

[0046] Next, depending on whether the newborn currently needs to be fed, if feeding is needed, first apply force to rotate and pull the docking tube 7 so that the locking block 60 is free from the obstruction of the elastic clamping block 64. The locking block 60 passes through the arc groove 62 and the strip groove 61 in sequence until the locking block 60 is free from the slot 63, thereby achieving the separation of the docking tube 7 and the docking head 4.

[0047] Afterwards, according to the connection method of the docking tube 7 and the docking head 4 mentioned above, the nipple 8 is connected to the cylinder 2, the cylinder 2 can be tilted, and the colostrum in the cylinder 2 can be fed to the newborn. In the middle of feeding, the cylinder 2 with the nipple 8 is removed, the locking block 34 can be pushed to release the lock on the piston 31, and the control button 30 can be slightly turned to drive the colostrum in the cylinder 2 to move toward the nipple 8, so as to facilitate the newborn to suck.

[0048] If the newborn does not need to be fed temporarily, the cover 9 and the cylinder 2 can be connected by the connection method of the above-mentioned docking tube 7 and the docking head 4 to achieve temporary sealing of the cylinder 2 and place it in a medical refrigerator for refrigeration.

[0049] The above is a preferred embodiment of the present invention. A person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements shall also be regarded as within the protection scope of the present invention.
