Description

Air bag type freeze-drying flash release agent device

Technical Field

The utility model belongs to the technical field of freeze-drying is dodged and is released agent use, in particular to gasbag type freeze-drying is dodged and is released agent device.

Background

The freeze-dried flash release preparation is a quick release preparation prepared by accurately filling a dispersion solution of an active substance and auxiliary materials such as a binder, a skeleton supporting agent and the like into a mould and then performing freeze-drying and molding. Since the water-free state is almost maintained, there is no fear of deterioration and oxidation of the active material due to the water environment, and therefore, there is no need to specially add additives such as preservatives and antibacterial agents which may cause adverse effects on the human body or the skin. Meanwhile, no heating treatment link is needed in the preparation process, so that the thermosensitive components in the active substances are well guaranteed.

Because the lyophilized quick-release agent is required to be quickly dissolved in water when in use, the lyophilized quick-release agent is often relatively fragile and easy to break and pulverize in the transportation and storage processes, thereby not only influencing the integrity and the attractiveness of the appearance, but also causing the loss of components.

simultaneously, the gas filled gasbag 4 is accomodate in the section of thick bamboo chamber of sleeve 1 through self deformation, specifically is: the airbag 4 is a structure similar to a flower shape, which is formed by gathering the circumference of the flat structure which is vertical in the axial direction in the above paragraph upwards and inwards, and is stored in the cylindrical cavity of the sleeve 1, therefore, the operation process of storing the airbag 4 in the cylindrical cavity of the sleeve 1 is as follows: the seat body 3 on the air bag mechanism is vertically downwards coaxially matched and plugged into the cavity of the sleeve 1, and the air bag 4 on the seat body 3 is driven to deform and squeeze into the sleeve 1, and finally the structure similar to the flower-shaped structure described in the section is shown in the attached figure 1,

wherein, the inner cavity wall of the sleeve 1 is horizontally and annularly and inwardly protruded (integrally formed) to form a first snap ring 12 which is coaxially arranged with the sleeve 1, the seat body 3 is correspondingly and annularly and outwardly protruded (integrally formed) to form a second snap ring 32 which is coaxially arranged with the seat body 3, the inner ring diameter of the first snap ring 12 is slightly smaller than the outer ring diameter of the second snap ring 32, and naturally, the first snap ring 12 stops the second snap ring 32 from passing through, the arrangement is mainly for avoiding the seat body 3 from being upwards pushed out of the sleeve 1 along with the air bag 4 thereon in the subsequent use process,

therefore, when the above-mentioned mechanism is assembled, the seat body 3 on the air bag mechanism is inserted into the sleeve 1 in a vertically downward coaxial matching manner, a certain downward pressure is applied, the second snap ring 32 is vertically extruded downwards through the annular cavity of the first snap ring 12 and then is further matched and moved downwards until the air bag 4 is extruded into the cylindrical cavity of the sleeve 1 and is away from the cylindrical opening at the top of the sleeve 1 for a certain distance according to the above-mentioned structure deformation similar to a flower shape, then the sleeve 1 is inverted and just inserted into the positioning groove cavity, because the air bag 4 in an inflated state is always provided with a tendency of elastic recovery when being accommodated in the cylindrical cavity of the sleeve 1, the air bag 4 is always pressed tightly outwards in the circumferential direction against the inner cavity wall of the sleeve 1, and depending on the friction force between the air bag 4 and the inner cavity wall of the sleeve 1 at the moment, the air bag mechanism cannot be in the cylindrical cavity of the sleeve 1 after the sleeve 1 is inverted,

the filling needle vertically and downwards sequentially passes through the pore canal 31 and the water delivery pipe 5 in a clearance fit manner and is close to the bottom of the groove cavity of the positioning groove, the position of the filling needle is kept still, the water-based front liquid preparation is injected into the barrel cavity of the sleeve 1 through the filling needle (after the liquid injection operation is finished, the liquid level of the front liquid preparation in the sleeve 1 can not contact with the air bag mechanism in the sleeve 1), after full freeze-drying, the filling equipment is moved upwards to extract the filling needle, then the sleeve 1 is taken out from the positioning groove and turned over to reset the sleeve 1, the freeze-drying flash release agent 2 with the through hole 21 is filled in the sleeve 1 close to the barrel opening at the top, and finally a protective cover 9 is covered at the opening at the top of the sleeve 1 in a matching manner to better form mechanical protection for the freeze-drying flash release agent 2 in the inner cavity of the sleeve 1, so as to facilitate the transportation and storage of the freeze-drying flash release agent 2,

in the above assembled mechanism, when the seat body 3 is matched and moved upwards in the cavity of the sleeve 1 to push the air bag 4 upwards, the wetted water-absorbing material layer 41 on the air bag 4 is firstly contacted upwards with the freeze-drying flash-release agent 2 to dissolve the freeze-drying flash-release agent, and then the air bag 4 is extended upwards out of the sleeve 1 through the opening at the top of the sleeve 1, at this moment, the air bag 4 loses the constraint of the sleeve 1 and is unfolded into a flat structure which is vertical in the axial direction again, and meanwhile, the dissolved freeze-drying flash-release agent 2 is distributed and loaded on the upper surface of the air bag 4 (the arrangement of the through holes 21 on the freeze-drying flash-release agent 2 is just for realizing ventilation more smoothly, so that the operation of injecting water upwards into the water-absorbing material layer 41 on the air bag 4 and the operation of upward pushing up of the air bag mechanism can be both more smoothly realized),

in addition, the barrel body ring at the top opening of the sleeve 1 protrudes outwards and extends to form a circle of supporting plate 11 with a horizontal plate surface, the outward extension amplitude (i.e. the width of the supporting plate 11 ring away from the sleeve 1) corresponds to the radial dimension of the flat structure formed by the automatic unfolding of the airbag 4 after it leaves the top opening of the sleeve 1 upwards, and as shown in fig. 3: when the airbag 4 almost just leaves the constraint of the sleeve 1 completely and is unfolded and restored to be in a flat structure, in the cavity of the sleeve 1, the first snap ring 12 just abuts against and blocks the second snap ring 32 to pass through the second snap ring from the middle part to the upper part, so that the seat body 3 cannot move upwards relative to the sleeve 1 continuously, the airbag 4 is in a springing-open state at the moment and is clamped at the opening at the top end of the sleeve 1, the airbag cannot be stored into the sleeve 1 by itself, and the bottom of the airbag 4 is close to the support plate 11 downwards;

the following is an introduction of a liquid feeding device matched with the freeze-drying flash release agent protection mechanism:

the seat body 3 is downwards detachably arranged and communicated on the liquid feeding device, the liquid feeding device comprises an upper tank body 6 and a lower tank body 7 which are arranged up and down and detachably connected together, the upper tank body 6 and the lower tank body 7 are coaxially arranged and are vertical in the axial direction,

a water outlet pipe 61 which is communicated with the inner cavity of the upper tank body 6 and the outside is vertically and upwards extended from the top of the upper tank body 6, the water outlet pipe 61 and the upper tank body 6 are coaxially arranged, the bottom of a pore canal 31 on the seat body 3 is arranged in an expanding opening, the expanding opening and the pore canal 31 are coaxially arranged, the seat body 3 is downwards matched and covered on the top end of the water outlet pipe 61 through the expanding opening to realize the detachable installation and connection with a liquid feeding device, a horizontal ring on the inner cavity wall of the expanding opening is inwards protruded (integrally formed) to form a third clamping ring 311 which is coaxially arranged with the expanding opening, a corresponding horizontal ring on the outer tube wall of the water outlet pipe 61 close to the top end of the water outlet pipe is outwards protruded (integrally formed) to form a fourth clamping ring 611 which is coaxially arranged with the water outlet pipe 61, the inner ring diameter of the third clamping ring 311 is slightly smaller than the outer ring diameter of the fourth clamping ring 611, and under the natural state, the fourth clamping ring 611 is prevented by the third clamping ring 311 from passing through the fourth clamping ring 611,

the top of the lower tank body 7 is provided with a through hole 71 communicated with the outside and the inner cavity of the lower tank body 7, the through hole 71 and the lower tank body 7 are coaxially arranged, the top of the lower tank body 7 annularly and vertically protrudes upwards to form a first assembling ring 72 coaxially arranged with the lower tank body 7, and the outer annular wall of the first assembling ring 72 is provided with an external thread (not shown in the figure); the bottom of the upper tank body 6 is annularly and vertically protruded downwards to form a second assembling ring 62 which is coaxially arranged with the upper tank body 6, the inner ring wall of the second assembling ring 62 is provided with an internal thread (not shown in the figure), and the second assembling ring 62 is sleeved and installed on the first assembling ring 72 in a threaded fit manner through the screw fit and screwing between the external thread and the internal thread, namely the detachable installation and connection between the upper tank body 6 and the lower tank body 7 are realized,

an installation frame 63 is fixedly installed in the inner cavity of the upper tank body 6 (the installation frame 63 is a grid-shaped hollow support, the lower part is the same), a liquid pumping pump body 8 is fixedly installed on the installation frame 63, the liquid pumping pump body 8 extends outwards to form a discharging pipe 81 and a feeding pipe 82, the discharging pipe 81 is far away from the liquid pumping pump body 8 along the length direction of the discharging pipe and extends into the inner cavity of the upper tank body 6 to be hermetically communicated with a bottom end pipe opening of the water outlet pipe 61; the feed pipe 82 is away from the liquid-pumping pump body 8 along the length direction, and is firstly matched downwards to penetrate through the mounting frame 63 and the bottom plate of the upper tank body 6, and then extends into the inner cavity of the lower tank body 7 through the through hole 71.

When in use, the protective cover 9 is taken down,

the partial section of the seat body 3 extending out of the bottom opening of the sleeve 1 downwards is pinched by hands, the seat body 3 covers the top end opening of the water outlet pipe 61 through the downward coaxial matching of the flaring, the seat body 3 is pulled downwards to enable the fourth clamping ring 611 to vertically and upwards rub and extrude from the annular cavity of the third clamping ring 311, and meanwhile, the water outlet pipe 61 is almost upwards jacked to the horizontal step surface of the flaring of the pore passage 31, so that the basic clamping between the seat body 3 and the water outlet pipe 61 is realized, as shown in the attached figures 4 and 6. Thus, in the subsequent water supply wetting process, the seat body 3 can be prevented from being washed off from the top end of the water outlet pipe 61 by water spraying, the sleeve 1 and the air bag mechanism can be prevented from falling off from the liquid supply device in the subsequent use process,

then the liquid pumping pump body 8 is controlled by a switch (not shown in the figure) on the liquid feeding device to sequentially pass through the feeding pipe 82, the liquid pumping pump body 8, the discharging pipe 81, the water outlet pipe 61, the pore passage 31 and the water conveying pipe 5, the water filled in the lower tank body 7 is conveyed to the water absorbing material layer 41 and diffuses and wets the water absorbing material layer 41 until the water absorbing material layer 41 is fully wetted, the water feeding is stopped,

then the sleeve 1 is held still, the seat body 3 is pushed by the water outlet pipe 61 on the liquid feeding device to enable the seat body 3 to move upwards in the cavity of the sleeve 1 in a matching way, in the process, when the wet water absorbing material layer 41 is upwards contacted with the freeze-drying flash release agent 2, the wet water absorbing material layer 41 can be quickly dissolved and then absorbs and loads on the water absorbing material layer 41 (which is also caused by the characteristic that the freeze-drying flash release agent 2 is easy to absorb water and disintegrate), then the air bag 4 is upwards extended out of the sleeve 1 through the top opening of the sleeve 1, loses the constraint of the sleeve 1 and is re-expanded into a flat structure with the vertical axial direction, the freeze-drying flash release agent 2 is correspondingly distributed and loaded on the upper surface of the air bag 4 of the structure (when the air bag 4 almost just completely leaves the sleeve 1 and is expanded into the flat structure, the first snap ring 12 in the cylindrical cavity of the sleeve 1 also abuts against and blocks the second snap ring 32 to pass upward from the first snap ring, so that the seat body 3 cannot move upward relative to the sleeve 1, as shown in fig. 5, therefore, the blocking force of the first snap ring 12 against the second snap ring 32 needs to be significantly greater than the blocking force of the third snap ring 311 against the fourth snap ring 611, in the foregoing assembling process, the water pipe 5 and the connection ring 51 need to be pressed downward by the device, so that the second snap ring 32 on the seat body 3 forcibly pushes downward against the first snap ring 12 in the sleeve 1, and in the using process, only the manual operation is needed to push the fourth snap ring 611 on the water outlet pipe 61 upward through the third snap ring 311 in the flaring, and the water injection: in the scheme, the parts including the sleeve 1, the first snap ring 12, the seat body 3, the second snap ring 32, the water outlet pipe 61 and the fourth snap ring 611 are all made of plastic materials by molding,

at the moment, the liquid feeding device is held and the skin is smeared through the water absorbing material layer 41 on the air bag 4, so that the dissolved freeze-dried flash release agent 2 is transferred and smeared on the skin, and in the smearing process, water can be continuously supplemented to the water absorbing material layer 41 through the liquid feeding device, so that the freeze-dried flash release agent 2 adsorbed on the water absorbing material layer 41 is better extruded to the skin, and the utilization rate of the freeze-dried flash release agent 2 is improved.

After coating, the seat body 3 is pulled upwards away from the water outlet pipe 61, and the whole freeze-drying flash release agent protection mechanism is discarded or recycled; when the device is used again, the protection mechanism equipped with the freeze-drying flash release agent 2 is replaced with a new one, and the operation is repeated.

The freeze-drying flash release agent 2 in the scheme is formed in the barrel cavity of the sleeve 1 and is protected by the sleeve 1, so that the freeze-drying flash release agent is not easy to break and pulverize in the processes of transportation and storage; after the air bag 4 is pushed out of the sleeve 1 to be bounced open, an upper surface (similar to the size of a powder puff) which is loaded with the freeze-drying flash-release agent 2 and has a large area can be obtained, and the upper surface is also a contact surface with the skin during smearing, and after the area of the smearing contact surface is large, the upper surface is more convenient and faster to smear, and is different from the common powder puff: the device of the scheme has the advantages that the amount of the freeze-drying flash release agent 2 filled in the sleeve 1 is basically fixed through parameter setting in the assembly process stage, the conventional powder puff is directly dipped in essence by pinching the powder puff with hands when in use, the dipping amount is not easy to control,

simultaneously, gasbag 4 in this scheme rather than the water absorbing material layer 41 cooperation back of surface with skin contact, when leaning on, have great buffer thickness, can not make skin have the sensation of being collided with, but wherein only water absorbing material layer 41 has the moisture of guarantor and the load adsorption capacity to freeze-drying after dissolving out and dodge release agent 2, and the surface fabric of gasbag 4 is sealed airtight, and water and freeze-drying are dodged release agent 2 and all can't permeate in to gasbag 4. Thus, the dissolved freeze-dried flash release agent 2 is equivalently loaded on the surface of the air bag 4 in a concentrated manner, and is more easily transferred to the skin when being smeared, thereby promoting the absorption and the utilization rate of the preparation; if the air bag 4 below the water absorbing material layer 41 is replaced by an adsorbing material such as a sponge, although the buffering thickness can be kept unchanged and even the softness is better, when the sponge is effectively wetted, the water demand can be obviously increased, and the dissolved freeze-dried flash-release agent 2 can also diffuse into the sponge, so that the preparation is far away from the surface of the sponge and cannot be well transferred to the skin when being applied;

in addition, the supporting plate 11 at the top of the sleeve 1 plays a role in supporting and abutting against the air bag 4, so that the upper surface of the air bag 4 can be always in effective contact with the skin in the process of smearing the hand-held device, the situation that the part of the air bag 4 which is far away from the sleeve 1 in the horizontal direction is bent downwards to weaken the contact degree between the air bag 4 and the skin after the air bag is abutted against the skin is avoided,

in addition, gasbag 4 has the tendency that the bullet is opened when accomodating in sleeve 1 section of thick bamboo chamber and is resumeed, is equivalent to that 4 rings of gasbag outwards extrude the inner chamber wall of sleeve 1, and like this, gasbag 4 is hugged closely and is slided on sleeve 1 inner chamber wall, has effectively reduced the freezing-drying and has dodged the residue of releasing agent 2 on sleeve 1 section of thick bamboo chamber wall, has improved the ejection of compact rate of freezing-drying and dodging releasing agent 2 from sleeve 1.
