Description

Technical Field

[0001] The utility model belongs to the technical field of biomaterial processing, and particularly relates to a hand-held biomaterial UP mark pressing device. Background Art

[0002] With the gradual expansion of the medical market, the requirements for finished biomaterials are constantly increasing. In order to improve the output and competitive advantage of biomaterials, the thickness uniformity and uniform aesthetics of biomaterials should be maintained during the freeze-drying or drying of intermediates. At the same time, due to the different raw materials used in different biomaterials, the UP mark is introduced as a standard to distinguish the front and back of biomaterials in the finished product process. The UP mark pressing mold is mainly used to distinguish the front and back of biomaterials to meet the needs of subsequent processing.

[0003] The purpose of designing a UP mark pressing mold is to mark the front and back of the biological material, so as to facilitate the distinction of the finished biological material during use. However, the existing UP mark pressing method is mainly a manual pressing method, which is inefficient. The existing UP mark pressing mold is similar to the shape of an official seal, which requires fingers to hold and then press or press the UP mark on the surface of the biological material. This has the following problems:

[0004] The position of the UP mark is uncertain due to human operation; during the pressing process, the biological material may be pressed through due to human operation, affecting the quality of the finished product; during the pressing process, the human operator holds the UP mark pressing mold for too long, which is difficult to operate and wastes a lot of energy, resulting in different pressing effects or inadequate pressing effects for the same batch of biological materials; there is also the possibility of human operation errors, resulting in greater waste.

[0005] The existing manually operated UP mark pressing method fails to maximize the utilization rate of raw materials (such as pericardium and peritoneum), affecting the output, uniformity and aesthetics of biological materials; at the same time, this method relies on manual pressing, and the inconsistent pressure given by different operators will cause differences in each production process, which is not conducive to achieving standardization of product production.

[0006] In order to solve the above-mentioned problems existing in the existing UP mark pressing technology, the present invention proposes a hand-held biomaterial UP mark pressing device. The device can be adapted to various biomaterials, has the function of being usable for various materials, reduces the human risks brought by manual operation, improves product quality, output and uniform aesthetics, is easy to operate, and further improves efficiency.

[0010] The front end of the pressure grip is a handle head, and the pressing portion is located on the upper surface of the handle head;

[0011] A UP column is detachably mounted on the end of the handle head, and a UP mark of the UP column faces the upper surface of the bearing bottom plate;

[0012] A spring is also installed on the bearing base plate, and the spring abuts against the pressure handle.

[0013] Furthermore, a first groove is formed at the end of the handle head, and a second groove is formed on the lower surface of the handle head. The second groove passes through the first groove and forms a nail-shaped insertion groove with the first groove.

[0014] Furthermore, the handle head is laterally penetrated by two opposite threaded holes at the position of the first groove.

[0015] Preferably, the UP column includes a UP column body with a UP mark and a plug-in board fixedly connected to the end face of the UP column body with the UP mark, the plug-in board is matched and plugged into the first groove, and the UP column body with the UP mark is matched in size with the second groove.

[0016] The pressing portion is formed with a transitional pressing groove. Preferably, the surface of the transitional pressing groove is an anti-slip fingerprint line.

[0017] Furthermore, a group of support plates are provided at the position where the bearing base plate is rotatably connected to the pressure handle, and the support plates are rotatably connected to the end of the pressure handle via a rotating shaft.

[0018] Furthermore, the lower surface of the pressure handle is a planar structure.

[0019] Preferably, when the pressure handle is in a horizontal working state, the height between the connecting portion and the bearing base plate is the same as the height of the UP column between the bearing base plate and the handle head.

[0020] Furthermore, the supporting base plate is also marked with horizontal and vertical scale lines for determining the position of the biological material.

[0021] Furthermore, a group of clamping plates are installed on the bearing bottom plate, each of the clamping plates is provided with a clamping hole, and the spring is fixed through the clamping hole.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. In the hand-held biomaterial UP mark pressing device of the utility model, the upper surface of the pressure grip handle is composed of a connecting portion, a gripping portion, a force transmission portion and a pressing portion from the rear end to the front end. The arc structure from the gripping portion to the force transmission portion is first concave and then convex. In particular, with this arc structure that is first concave and then convex, in actual application, the gripping pressure of the palm on the gripping portion will be smoothly transmitted to the pressing portion through the force transmission portion, so that the UP mark pressing device of the utility model is labor-saving and the pressing force is concentrated, and super-labor-saving pressing, stable pressing force, and smooth pressing can be achieved.

[0024] 2. In the hand-held biomaterial UP mark pressing device of the utility model, a spring is also installed on the bearing base plate, and the spring abuts against the pressure handle, so that the UP column automatically opens and resets under the action of the spring after completing a pressing work; on the other hand, more importantly, due to the elastic effect of the spring, the force transmitted to the UP column will not press through or damage the biomaterial, thereby ensuring the quality of the biomaterial to a certain extent.

[0025] 3. In the hand-held biomaterial UP mark pressing device of the utility model, the front end of the pressure handle is the handle head, and the pressing part is located on the upper surface of the handle head; in this way, the final conduction force and pressing force are concentrated here, further acting on the UP column, achieving the effect of concentrated force.

[0026] 4. In the hand-held biomaterial UP mark pressing device of the utility model, a first groove is provided at the end of the handle head, and a second groove is provided on the lower surface of the handle head, the second groove penetrates the first groove and forms a nail-shaped plug-in groove with the first groove; the UP column includes a UP column body with a UP mark and a plug-in plate fixedly connected to the end face of the UP column body with the UP mark, the plug-in plate is matched and plugged with the first groove, and the UP column body with the UP mark matches the size of the second groove; so that the UP column can be stably fixed in the "nail-shaped plug-in groove", providing a quick installation method for the stable installation of the UP column.

[0027] 5. In the hand-held biomaterial UP mark pressing device of the utility model, the surface of the transitional pressing groove is an anti-slip fingerprint line, which can concentrate the gripping pressure here and also play a certain anti-slip role, making it convenient for staff to operate.

[0028] 6. In the hand-held biomaterial UP mark pressing device of the utility model, when the pressure handle is in a horizontal working state, the height between the connecting portion and the bearing base is the same as the height of the UP column between the bearing base and the handle head; this ensures that the pressure handle is parallel to the bearing base to press the UP mark on the biomaterial, avoiding problems such as angle deviation after the UP mark is pressed, resulting in low quality of the biomaterial; it can also prevent uneven thickness of the UP mark.

[0029] 7. In the hand-held biomaterial UP mark pressing device of the utility model, the bearing bottom plate is also marked with horizontal and vertical scale lines for determining the position of the biomaterial, which facilitates the positioning of biomaterials of different sizes and ensures the consistency and uniformity of the UP mark position of the biomaterial.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It should also be noted that the meaning of the "UP mark" in the present invention is not limited to the letters "UP", but can also refer to other symbols, letters, words, etc. used to distinguish the front and back or for marking.

[0036] Embodiment 1:

[0037] See also Figure 1 The present embodiment provides a hand-held biomaterial UP mark pressing device, including a bearing base plate 1, and the front surface of the bearing base plate 1 is marked with horizontal and vertical scale lines. For biomaterial films of different sizes (such as pericardium or peritoneum, etc.), positioning can be carried out according to these scales to determine the placement position; a group of clamping plates 11 are symmetrically arranged on both sides of the rear end of the bearing base plate 1, and a clamping hole 8 is opened at the position where each clamping plate 11 contacts the surface of the bearing base plate 1. The two clamping holes 8 can fix the spring 9, and the spring 9 is arranged at this position; after one pressing is completed, the spring 9 is used to drive the pressure handle to move away from the bearing base plate 1, open the pressure handle 2, and facilitate the placement of a new biomaterial film; at the same time, the spring 9 has a certain limiting effect on the pressure applied by the pressure handle 2, which is safe and reliable to use, and avoids pressing through the biomaterial, damaging the biomaterial film, and causing unnecessary waste.

[0038] At the same time, the rear end of the bearing base plate 1 is rotatably connected to the pressure handle 2 through a rotating shaft. In the present embodiment, specifically, a group of support plates 10 are installed on both sides of the rear end of the bearing base plate 1, and a rotating shaft is installed between the group of support plates 10. The rear end connecting portion of the pressure handle 2 is provided with a rotating hole, and the rotating shaft passes through the rotating hole to form a rotating connection method; of course, the support plates 10 on each side can also be connected to the rotating shaft by other rotating methods, for example, conventional methods such as bearing connection; it should be noted that, in the present embodiment, the lower surface of the pressure handle 2 is a planar structure, so as to ensure the uniformity of the UP mark and improve the product yield when pressing the UP mark; it should also be noted that the top end of the spring 9 is in contact with the bottom surface of the pressure handle 2, so as to facilitate the timely opening of the pressure handle 2; at the same time, it should be noted that the axial position of the spring 9 corresponds to the position of the gripping portion 4 to ensure that the gripping force can act on the spring 9 during pressing to avoid excessive force, which may cause the biomaterial to be pressed through or damaged.

[0039] The upper surface of the pressure grip 2 is composed of a connecting portion 3, a gripping portion 4, a force transmission portion 5 and a pressing portion 6 from back to front. The gripping portion 4 is a concave arc structure, and the force transmission portion 5 is a convex arc structure. Moreover, there is a continuous streamlined transition from the gripping portion 4 to the force transmission portion 5. This arrangement is that when the palm of the hand holds the gripping portion 4 and the thumb extends along the force transmission portion, the power of the palm can be smoothly transmitted to the front to form a combined force, which is very labor-saving and improves work efficiency. The front end is a handle head 7, and the pressing part 6 is located on the handle head 7 and is an elliptical concave groove. An anti-slip fingerprint line is formed on the surface of the concave groove. This setting is for anti-slip pressing on the one hand, and for the convenience of force on the other hand. In general, after the gripping part 4 is grasped by the palm of the hand, the force is transmitted to the pressing part 6 through the force transmission part 5, and the pressing is completed, and the UP mark pressing procedure is completed relatively smoothly. At the same time, the concave groove at the pressing part 6 on the handle head 7 can concentrate the force together to achieve a good effect.

[0040] See also Figure 1 and Figure 2 The front end surface of the handle 7 is provided with a first groove 71, and at the same time, the lower surface of the handle 7 is provided with a second groove 72, and the second groove 72 is connected with the first groove 71 after being opened, and finally forms an integrated "nail-shaped plug-in hole", and the "nail-shaped plug-in hole" is used to plug and fix the UP column 12, so that the UP column 12 is stably plugged and fixed on the handle 7, playing a role of stable support;

[0041] See also Figure 3 In this embodiment, the UP column 12 includes a UP column 121 with a UP mark, and a plug-in board 122 installed together with the UP column 121 with the UP mark. Specifically, the non-UP mark end face of the UP column 121 with the UP mark is fixedly connected to the plug-in board 122. It should be noted that the plug-in board 122 is installed in cooperation with the first groove 71, and the sizes of the two are matched; the width or diameter of the UP column 12 matches the width of the second groove 72, so that a stable plug-in fixation can be achieved. It is necessary to give an example that the UP column 121 with the UP mark can be a cylindrical structure or a rectangular structure. Furthermore, in this embodiment, in order to ensure that the UP column 12 is fixed safely and reliably, two threaded holes are symmetrically opened on both sides of the handle 7 located in the first groove 71, and the UP column 12 is further fixed by threads to prevent position movement or shaking.

[0042] In order to ensure that the UP column 12 can be kept horizontally pressed on the surface of the biomaterial membrane during the pressing process and will not cause damage to the biomaterial membrane, the present embodiment requires that when the lower surface of the pressure handle 2 is parallel to the upper surface of the bearing base plate 1, the height between the upper surface of the bearing base plate 1 and the linear surface of the connecting portion 3 is consistent with the height of the UP column located between the upper surface of the bearing base plate 1 and the lower surface of the handle head 7. That is to say, when the lower surface of the pressure handle 2 is in a horizontal position, the heights of the two must be consistent. Of course, in order to adapt to biomaterials or biomaterial membranes of different thicknesses, the height of the UP column 12 located between the bearing base plate 1 and the handle head 7 can be higher than the height between the bearing base plate 1 and the connecting portion 3, and the difference is controlled between 0.3 and 0.8 mm. This is because the thickness of most sheet or membrane biomaterials is around 0.3 to 0.8 mm.

[0043] It should be noted that the dimensions of the drawings in the technical solution do not represent the exact dimensions of the actual objects, and the drawings are only for the convenience of technicians to understand the structural type of the technical solution.

[0044] In addition, the solution of the utility model can also be designed as follows: the handle head 7 is improved, for example, the lower surface of the handle head 7 is designed to be horizontal, that is, to be parallel to the upper surface of the supporting base plate 1, so as to ensure the accuracy of the position when pressing the UP mark.

[0045] In actual use, generally, the index finger, middle finger, ring finger and little finger hold the bearing base plate 1, the palm is held on the gripping part 4, and the thumb is placed from the force transmission part 5 to the pressing part 6. The biomaterial is placed on the bearing base plate 1 with horizontal and vertical scale lines according to the position requirements, and the force is transmitted through the palm. At the same time, the pressing part 6 (handle head 7) is acted on to make the UP column 12 smoothly act on the surface of the biomaterial (such as pericardium) to form the UP mark. Release the pressure, and the spring 9 will pop the pressure handle 2 to end one work, and the cycle operation can be completed. Since in actual experiments and work, it is necessary to produce hundreds or even more biomaterials with UP marks, the hand-held biomaterial UP mark pressing device of the utility model can be completed more easily and can ensure the quality of the biomaterial.

[0046] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0047] Although the optional embodiments of the utility model embodiments have been described, those skilled in the art, once knowing the basic creative concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including optional embodiments and all changes and modifications falling within the scope of the utility model embodiments.
