DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] At present, the outlet of the external gel cream at the extrusion head is usually in the form of a relatively large circular groove. When the gel cream tube is squeezed, the squeezed gel cream is unevenly distributed on the surface of the wound in the form of thick strips, so that the gel cream is accumulated thickly on the surface of some wound areas, which in turn hinders the breathability of the wound, thereby increasing the chance of bacterial growth. In addition, an overly thick gel cream layer may hinder the growth of new skin cells at the bottom of the wound, delay the healing process, and cause waste of gel cream. In addition, when using fingers to flatten the gel cream accumulated on the surface of the wound, it is easy to affect the efficacy of the gel cream. In order to ensure that the gel cream exerts the maximum effect on the wound surface and achieves the uniformity of the gel cream application, please refer to the implementation methods disclosed in the following Examples 1 to 6.

[0033] Embodiment 1

[0034] In order to solve the problem that the gel cream needs to be squeezed out multiple times and the distribution of the application is uneven when applying the gel cream to treat large-area wounds with the traditional gel cream squeezer, please refer to Figure 1-Figure 8The present embodiment proposes a gel cream extruder with a constant speed cap, which can gradually and disperse the relatively thick and round-shaped gel cream, thereby effectively reducing the thickness of the extruded gel cream while increasing its coverage area, so that the gel cream can cover the applied area more evenly. The sealing cap 2 of the gel cream extruder is detachably mounted on the extrusion head 1 for providing protection. The nozzle structure 3 is threadedly connected to the inside of the extrusion head 1 and is used to store the gel cream. The outlet end of the extrusion head 1 is detachably mounted with an additional head 4 for evenly dispersing the gel cream to both sides when applying. The interior of the extrusion head 1 is provided with a conical groove 101 for uniformly discharging the gel cream. The additional head 4 includes an additional shell 401 inserted into the conical groove 101. The interior of the additional head 4 is provided with a connecting member that is interconnected with the conical groove 101 and is used to expand the gel cream. The special-shaped groove 402 of the gel cream extrusion coverage area is installed on the surface of the installation head 4, and several straight lines 403 are installed to make the extruded gel cream flat and evenly cover the applied area. A plurality of U-shaped grooves arranged up and down are opened on the straight lines 403. After the extrusion head 1, the nozzle structure 3 and the installation head 4 are assembled, the gel cream inside is driven to be discharged outward along the conical groove 101 of the extrusion head 1 by squeezing the nozzle structure 3. The morphological structure of the conical groove 101 can make it easier to extrude the gel cream, and can obtain a uniform discharge speed, and then conveniently and accurately control the usage amount. Then, the relatively thick and round gel cream is gradually dispersed and extruded by using the structural form of the installation head 4, thereby effectively reducing the thickness of the extruded gel cream while increasing its coverage area, so that the gel cream can be more evenly covered on the applied area. After the gel cream is covered, the entire extruder is driven to move horizontally or axially forward and backward along the surface of the applied area to achieve the effect of spreading the gel cream.

[0035] Compared with the traditional gel cream squeezer, when pressing and squeezing, the gel cream squeezed out is generally in the shape of a round strip, and the squeezed amount is relatively large, so that the gel cream covering the wound surface is too thick. In order to solve this problem, the present embodiment divides the special-shaped groove 402 into a transition groove 4021, a collecting groove 4022 and a diverter groove 4023 from the top surface to the bottom surface of the mounting head 4, and the number of the diverter grooves 4023 is not less than one group, and the transition groove 4021 is in the shape of a truncated cone with a narrow top and a thick bottom, which is beneficial to improving the discharge speed of the gel cream from the inside of the conical groove 101 to the collecting groove 4022 and increasing the uniformity of distribution in the collecting groove 4022. The diameter of the top section of the collecting groove 4022 is consistent with that of the transition groove 4021 and the bottom surface is arranged in an arc shape, which is beneficial for the gel cream inside the collecting groove 4022 to be completely discharged along the diverter groove 4023 when squeezed. The diverter groove 4023 is in the shape of a thick top and a thin bottom, which is more beneficial to controlling the extrusion amount and reducing the thickness of the discharged gel cream by limiting the outflow speed of the gel cream.

[0036] Compared with the traditional gel cream extruder, when applying, the gel cream is in a round strip shape after being squeezed out, so it cannot be applied to some small or difficult-to-apply skin surfaces. In order to solve this problem, the present embodiment adopts an additional shell 401 made of silicone material, and the discharge end of the additional shell 401 is flat, which can be bent accordingly according to the curvature of the wound under the action of external force. At the same time, the flat shape can more accurately squeeze the gel cream to some small or difficult-to-apply skin surfaces, such as around the eyes or between the fingers.

[0037] The extrusion head 1 and the installation head 4, the nozzle structure 3 and the sealing cap 2 are all designed with a detachable module, which is convenient for cleaning and sterilization of the extruder and the sealing cap 2, ensuring that the extruder and the sealing cap 2 meet the sterility requirements of sterile preparation products. At the same time, whether to use the installation head 4 can be selected according to application requirements to increase the diversity of the gel cream extrusion form.

[0038] The connecting line between the center of the top surface of the additional shell 401 and the midpoint of the bottom is inclined toward the side of the straight line 403, which is conducive to the user to maintain a comfortable state to squeeze out the gel cream. A threaded ring 404 is installed on the outer surface of the additional shell 401 for firmly combining with the extrusion head 1. The threaded ring 404 is wrapped around the connecting gap between the additional shell 401 and the extrusion head 1, so as to improve the sealing and reduce the probability of gel cream overflow.

[0039] The following embodiments 2 to 6 are all different implementation methods based on the above-mentioned embodiment 1, and the same parts will not be repeated in detail.

[0040] Embodiment 2

[0041] like Figure 4-Figure 5 , Figure 7 As shown, the diverter slot 4023 is arranged in the form of multiple groups of columnar slots with thick top and thin bottom and is installed inside the housing 401, and is interconnected with the collecting slot 4022, which can effectively expand the distribution area of ​​the entire diverter slot 4023, and at the same time ensure that the gel cream is evenly dispersed from the inside of the multiple columnar slots, avoiding excessive concentration of the gel cream in a local area, so that the gel cream can be evenly covered on the skin surface that needs to be treated in the form of dots or multiple straight lines. In addition, the outlets are numerous and small, which can make the gel cream adhere to the outlet end better, not easy to drip or flow, thereby reducing the waste of the gel cream, and the design of the small outlet can effectively reduce the contamination of the drug by environmental factors such as oxygen and external bacteria, thereby maintaining the purity of the gel cream and reducing the risk of drug failure or cross-interference.

[0042] Embodiment 3

[0043] like Figure 4-Figure 6As shown, the diverter groove 4023 is in the shape of a single flat groove, so that when squeezed, the gel cream passing through the diverter groove 4023 gradually extends to both sides with a width and gradually decreases in thickness, thereby achieving a uniform thin coating effect on multiple areas.

[0044] Embodiment 4

[0045] When the extruder is not in use, the user's fingers may unconsciously apply external force to the surface of the nozzle structure 3 during the process of inserting its front end into the sealing cap 2, thereby causing the gel cream to leak out of the front end overflow port of the extruder. In addition, the front end overflow port of the extruder directly fits the inner wall of the sealing cap 2. When the sealing cap 2 is subsequently separated from the extruder, part of the gel cream will be taken away from the extruder along with the inner wall of the sealing cap 2, thereby causing a waste of the gel cream. In order to effectively avoid this problem, Figure 1 , Figure 4-Figure 7 As shown, a cover sheet 405 is fixedly installed on the bottom of one side of the additional shell 401 away from the straight stripe 403, and a sealing structure 4051 for sealing the outlet end of the diverter slot 4023 is installed on the cover sheet 405. The shape of the sealing structure 4051 is set according to the shape of the outlet end of the diverter slot 4023, and the sealing structure 4051 and the cover sheet 405 are both made of silicone material, which has a certain softness and plasticity. By flipping the cover sheet 405 to cover the outlet end surface of the additional shell 401 and squeezing the sealing structure 4051 into the diverter slot 4023, the extruder outlet can be blocked to avoid leakage of the gel cream, thereby ensuring that the position where the inner wall of the sealing cap 2 contacts the installation head 4 remains clean.

[0046] like Figure 1 , Figure 4 and Figure 6 As shown, in order to prevent the cover sheet 405 from drooping at the overflow outlet at the front end of the mounting head 4 and affecting the discharge of materials during the use of the extruder, two T-bars 4052 arranged front to back are installed on the cover sheet 405, and two groove pieces 4053 arranged front to back and used for clamping the T-bars 4052 are installed on the side of the mounting shell 401 away from the straight line 403. The T-bars 4052 and the groove pieces 4053 are both made of rubber material. After the sealing cap 2 is removed from the extruder head 1, the cover sheet 405 made of silicone material is flipped and fitted to one side of the mounting shell 401 by moving it, and the cover sheet 405 is squeezed to gradually deform the T-bars 4052 and the groove pieces 4053 made of plastic material, and the T-bars 4052 are clamped inside the groove pieces 4053, thereby achieving the purpose of fixing the position of the cover sheet 405 and preventing it from interfering with the discharge of the gel cream.

[0047] Embodiment 5

[0048] In order to prevent the gel cream from overflowing from the gap between the nozzle structure 3 and the extruder head 1, Figure 1-Figure 2 As shown, a clamping ring 102 is installed inside the extrusion head 1, and its bottom is fitted with the top of the nozzle structure 3, so as to avoid overflow pollution and waste when the gel cream is squeezed out. A locking outer thread is provided on the outer surface of the extrusion head 1, and the nozzle structure 3 and the extrusion head 1 are threadedly connected to the tightest state. The clamping ring 102 can fit tightly with the outlet end of the nozzle structure 3, and the inner diameter of the clamping ring 102 is consistent with the inner diameter of the nozzle structure 3, thereby avoiding obstruction of the discharge of the gel cream inside the nozzle structure 3.

[0049] Embodiment 6

[0050] Before the nozzle structure 3 is used in combination with the extruder head 1, the sealed end of the nozzle structure 3 needs to be opened, such as 1 and Figure 3 As shown, in order to facilitate opening the sealing end of the nozzle structure 3, a groove 201 is provided at one end of the sealing cap 2, and a conical thorn head 202 for opening the seal of the gel cream is installed inside the groove 201. The sealing cap 2 is provided with an L-shaped groove located outside the groove 201, and a silicone sealing cover 203 for closing the opening on the groove 201 is detachably installed at one end of the sealing cap 2 through the L-shaped groove. The height of the conical thorn head 202 is 4 / 5 of the depth of the groove 201, thereby reducing the probability of the silicone sealing cover 203 being punctured by the conical thorn head 202. 3 is composed of a covering part whose bottom diameter is larger than the inner diameter of the groove 201 and a snap-fitting part adapted to the L-shaped groove, and it has certain softness and plasticity. When an external force is applied to it, its shape can be changed to a certain extent. Therefore, it is squeezed toward the inside of the L-shaped groove, and its snap-fitting part can be gradually deformed and inserted into the L-shaped groove, so that the silicone sealing cover 203 is more firmly attached to the sealing cap 2, effectively preventing the internal space of the groove 201 and the conical thorn head 202 from being contaminated, which affects the efficacy of the gel cream opened by the conical thorn head 202.

[0051] like Figure 1-Figure 3 , Figure 8 As shown, the sealing cap 2 is a conical structure, and the outer surfaces of the sealing cap 2 and the extrusion head 1 are provided with a plurality of anti-slip grooves arranged in a ring shape. The inner wall of the sealing cap 2 is provided with locking inner threads that match the locking outer threads. The concave parts of the anti-slip grooves are designed with arcs on both sides, which can increase friction while preventing damage to fingers.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
