Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, and it is a kind of defibrillation handle, defibrillation equipment and defibrillation handle mould. BACKGROUND

[0002] Defibrillation equipment usually includes left defibrillation handle, right defibrillation handle, left electrode and right electrode. Left electrode is connected to left defibrillation handle, and right electrode is connected to right defibrillation handle. The structure of left defibrillation handle is same as the structure of right defibrillation handle.

[0003] In the prior art, left defibrillation handle includes inner mold and outer mold covered on the outer of inner mold, connecting piece is arranged in inner mold, and connecting piece is used to be electrically connected with left electrode. The material of inner mold is usually hard material, and it constitutes the main structure of left defibrillation handle, and the material of outer mold is usually relatively soft and has certain elasticity, which is convenient for user to grip and can also prevent slipping. In the prior art, inner mold is formed by injection molding. Because the size requirement of inner mold is high, the positioning requirement of inner mold is also high during injection molding, and positioning needle needs to be added during injection molding to ensure the relative position of formed inner mold and connecting piece. Because positioning needle is arranged, the inner mold formed by injection molding will have through hole. After outer mold is formed outside inner mold, the position corresponding to the through hole of inner mold will collapse, causing the appearance of left defibrillation handle to be poor. And because there is gap between inner mold and outer mold at the position of through hole, inner mold and outer mold cannot be better adhered, causing the connection strength of inner mold and outer mold to be low, and they are more likely to separate.

[0004] Therefore, a defibrillation handle and defibrillation equipment with high connection strength are needed. INVENTION CONTENTS

[0044] The technical scheme of the utility model will be further illustrated below by specific embodiments in conjunction with the drawings.

[0045] In the first aspect, the utility model provides a defibrillation handle, which can have higher connection strength.

[0046] As shown in Figures 1 to 6 The defibrillation handle 10 includes an inner mold 100, a filler 200 and an outer mold 300. The outer mold 300 is wrapped outside the inner mold 100.

[0047] Exemplarily, the inner mold 100 has a connecting surface 110 for combining with the outer mold 300. In some optional embodiments, the entire outer surface of the inner mold 100 is the connecting surface 110, that is, the outer surface is wrapped on the inner mold 100. As shown in Figure 2 And Figure 3As shown, the connecting surface 110 is provided with a rough structure 120, which can increase the roughness of the connecting surface 110, and further increase the specific surface area of the connecting surface 110. In addition, the inner mold 100 has an injection hole 130, which is the position of the positioning pin on the mold when the inner mold 100 is injection molded, and can improve the dimensional accuracy of the inner mold 100. In this embodiment, the filler 200 is filled in the injection hole 130 to block the injection hole 130, so that when the outer mold 300 is formed, the problem of collapse of the outer mold 300 does not occur. In addition, the end surface of the filler 200 exposed from the injection hole 130 is flush with the surface of the inner mold 100, so as to ensure the smoothness of the inner mold 100, and further improve the connection strength when the outer mold 300 is connected with the inner mold 100.

[0048] The outer mold 300 in this embodiment is injection molded on the connecting surface 110 of the inner mold 100, the outer mold 300 covers the rough structure 120, and the rough structure 120 and the outer mold 300 are connected as a whole, and the outer mold 300 and the filler 200 are connected as a whole. In this way, the connection strength and connection reliability of the outer mold 300 and the inner mold 100 can be improved. It should be noted that after the inner mold 100 is obtained, the filler 200 is filled in the injection hole 130, and then the inner mold 100 is placed in the mold for forming the outer mold 300, so that the mold for forming the outer mold 300 and the inner mold 100 form a glue injection cavity, and then the injection liquid for forming the outer mold 300 is injected into the glue injection cavity. The injection liquid fills the glue injection cavity and contacts the rough structure 120 and the filler 200, and the injection liquid also enters the gap between the filler 200 and the injection hole 130, and solidifies to form an integral whole with the inner mold 100 and the filler 200, improving the integrity of the defibrillation handle 10. It can be understood that when the temperature of the injection liquid is relatively high, the injection liquid can melt the rough structure 120 and part of the filler 200, so that the formed outer mold 300 is integrated with the rough structure 120, and the end of the filler 200 is integrated, further improving the connection strength of the inner mold 100 and the outer mold 300.

[0049] The defibrillator handle 10 provided in this embodiment has a roughened structure 120 on the connecting surface 110 of the inner mold 100, and the filler 200 is filled in the injection through hole 130 of the inner mold 100. This allows the filler 200 to support the outer mold 300 during injection molding, preventing the outer mold 300 from collapsing at the position corresponding to the injection through hole 130. This ensures the appearance of the defibrillator handle 10, reduces the problem of poor appearance of the defibrillator handle 10, and reduces the possibility of irregular depressions in the defibrillator handle 10. It also facilitates the high-temperature sterilization of the defibrillator handle 10. The roughened structure 120 on the connecting surface 110 increases the specific surface area of ​​the inner mold 100, allowing for a larger connection area when the inner mold 100 and the outer mold 300 are connected. This enables the inner mold 100 and the outer mold 300 to be better connected as a whole, improving the connection strength between the inner mold 100 and the outer mold 300, reducing the risk of separation between the inner mold 100 and the outer mold 300, and providing high reliability.

[0050] The specific structure of the rough structure 120 can be varied. In one embodiment, such as... Figure 2 As shown, the rough structure 120 has a straight stripe structure, which facilitates the processing and manufacturing of the rough structure 120. For example... Figure 3 As shown, the rough structure 120 consists of protrusions, making its structure relatively simple. In other embodiments, the rough structure 120 can also be a wavy structure, pits, etc., all of which can achieve the purpose of increasing the specific surface area of ​​the connecting surface 110. This embodiment does not limit this.

[0051] For example, such as Figure 1 As shown, the inner mold 100 is flattened cylindrical, and the defibrillator handle 10 is also flattened cylindrical for easy gripping by the user. Figure 4 As shown, the inner mold 100 has two feature surfaces 140 disposed opposite each other in its thickness direction. The feature surfaces 140 are part of the connecting surface 110. An injection through-hole 130 is disposed through both feature surfaces 140, that is, the injection through-hole 130 penetrates the inner mold 100 along its thickness direction. This improves the positioning effect of the inner mold 100 during injection molding, resulting in higher dimensional accuracy of the inner mold 100.

[0052] In some optional embodiments, multiple injection-molded through holes 130 and fillers 200 are provided in a one-to-one correspondence, with each filler 200 filling the corresponding injection-molded through hole 130, so that each injection-molded through hole 130 can be sealed to ensure the appearance of the defibrillator handle 10.

[0053] To further increase the specific surface area when the inner mold 100 and the outer mold 300 are connected, and to reduce the probability of the outer mold 300 moving relative to the inner mold 100, in this embodiment, each feature surface 140 is provided with a first processing groove group 150 and a second processing groove group 160. The first processing groove group 150 includes a plurality of first grooves 151, and the second processing groove group 160 includes a plurality of second grooves 161. Correspondingly, the outer mold 300 has a plurality of first protrusions (not shown in the figure) fixed one-to-one in the first grooves 151 and second protrusions (not shown in the figure) fixed one-to-one in the second grooves 161. In this way, the cooperating first grooves 151 and first protrusions, as well as the second grooves 161 and second protrusions, can limit the relative position of the inner mold 100 and the outer mold 300 in the axial direction of the inner mold 100, reduce the probability of relative movement between the inner mold 100 and the outer mold 300, and ensure the adhesion effect between the inner mold 100 and the outer mold 300. Among them, the injection molding through hole 130 is provided in the first processing groove group 150.

[0054] In some optional embodiments, a plurality of first grooves 151 are spaced apart along the width direction of the inner mold 100, and each first groove 151 has an injection through hole 130 in its groove wall. In this embodiment, a plurality of second grooves 161 are spaced apart along the length direction of the inner mold 100. In this way, the space of the feature surface 140 can be fully utilized, and the connection strength between the inner mold 100 and the outer mold 300 can be improved.

[0055] Since one end of the defibrillator handle 10 is typically connected to an electrode and the other end is typically connected to a lead wire 30, if the defibrillator handle 10 is initially straight, it will affect ease of use, and the connection between the lead wire 30 and the defibrillator handle 10 will be bent, making the lead wire 30 more prone to breakage. Alternatively, as Figure 2 As shown, the internal mold 100 in this embodiment includes a mold body 170 and a head 180 connected to one end of the mold body 170. The cross-sectional area of ​​the mold body 170 is smaller than that of the head 180, and the angle between the mold body 170 and the head 180 is greater than 90 degrees and less than 180 degrees. By providing a head 180 with a larger cross-section, installation space is provided for components such as control switches and controllers. By setting the mold body 170 and the head 180 at an angle, with the wire 30 connected to the end of the head 180 facing away from the mold body 170 and the electrode connected to the mold body 170, on the one hand, it is easier to grip, and the wire 30 does not extend towards the user, thus facilitating operation; on the other hand, the degree of bending of the wire 30 is smaller, reducing the probability of wire breakage and thus reducing the probability of damage to the defibrillator. For example, the angle between the mold body 170 and the head 180 is 145°, 150°, etc.

[0056] It should be noted that the injection through hole 130, the first groove 151 and the second groove 161 are all located on the mold body 170.

[0057] In some optional embodiments, as shown in Figure 5 The bottom of the outer mold 300 is provided with anti-skid protrusions 310. The anti-skid protrusions 310 can increase the friction between the outer mold 300 and the user's hand, thereby reducing the probability of the hand slipping relative to the outer mold 300, and improving the stability and reliability of holding the defibrillation handle 10. For example, the anti-skid protrusions 310 can be provided in multiple numbers, and the multiple anti-skid protrusions 310 are uniformly distributed on the bottom of the outer mold 300. Alternatively, the anti-skid protrusions 310 can include protrusions with small sizes and protrusions with large sizes. The protrusions with small sizes can be used to contact the fingers, and the protrusions with large sizes can be located in the finger gaps, so as to facilitate the user to hold the defibrillation handle 10 at a suitable position according to the needs.

[0058] Please continue to refer to Figure 5 , part of the outer mold 300 protrudes outward along the axis direction perpendicular to the outer mold 300 and extends along the circumferential direction of the outer mold 300 to form a boss 320. In this way, when the defibrillation handle 10 needs to be placed on the table, the boss 320 and the head 180 with a large cross-sectional area support the defibrillation handle 10, so that there is a gap between the outer mold 300 and the table, facilitating the next use of holding the defibrillation handle 10, and facilitating the use of the defibrillation device.

[0059] The defibrillation handle 10 provided by the embodiment has high connection strength between the inner mold 100 and the outer mold 300, and reduces the probability of connection failure between the inner mold 100 and the outer mold 300. In addition, by arranging the filling piece 200, the appearance yield of the defibrillation handle 10 can be ensured. Since the appearance of the outer mold 300 is defective, the outer mold 300 needs to be disassembled and then a new outer mold 300 is formed. However, the disassembly of the outer mold 300 is difficult and has low efficiency, and the cost of the material is high. Therefore, the cost of the defibrillation handle 10 provided by the embodiment can be low. In addition, the inner mold 100 and the outer mold 300 are tightly connected together, and there is no sterilization blind area when the defibrillation handle 10 is subjected to high-temperature sterilization, thereby improving the effect of high-temperature sterilization and further improving the safety of the defibrillation handle 10. In some optional embodiments, after the inner mold 100 is formed, a baking process can be added to the inner mold 100, which is beneficial to the adhesion effect of the outer mold 300 after being formed to the inner mold 100, and further improves the stability and reliability of high-temperature sterilization.

[0060] In a second aspect, the embodiment provides a defibrillation device with high reliability and strong connection strength.

[0061] For example, as shown in Figure 6As shown, the defibrillation device includes two defibrillation handles 10 as in the first aspect. The defibrillation device also includes two electrode assemblies 20. Among them, the two electrode assemblies 20 correspond to the two defibrillation handles 10 one by one, each electrode assembly 20 includes an electrical connector passing through the inner mold 100 of the defibrillation handle 10 corresponding thereto, and an electrode piece electrically connected to the electrical connector and connected to one end of the inner mold 100. The two electrode pieces can cooperate to achieve defibrillation. In this embodiment, the use mode of the defibrillation device can refer to the prior art, which will not be described in detail here.

[0062] Optionally, the electrical connector is connected with a wire 30, the electrode piece is led out from one end of the defibrillation handle 10, the wire 30 is led out from the other end of the defibrillation handle 10, and the two wires 30 are connected and connected with the connector 40, and then connected with the power supply through the connector 40, to realize the power supply for the electrode piece.

[0063] In a third aspect, the embodiment provides a defibrillation handle mold (not shown in the figure) for injection molding to form the defibrillation handle 10 as in the first aspect. Among them, the defibrillation handle mold includes a first mold and a second mold. The first mold is used for injection molding to form the inner mold 100, and the second mold is used for injection molding to form the outer mold 300. The first mold is provided with a rough surface corresponding to the connecting surface 110, and the rough surface has a matching structure matched with the rough structure 120, and the matching structure is used to form the rough structure 120 during injection molding.

[0064] The defibrillation handle mold provided by the embodiment has a simple structure and can be improved on the basis of the original mold, for example, the matching structure can be formed on the original mold, which can have a lower cost.

[0065] In some optional embodiments, as shown in the figure, Figure 7 As shown, the inner mold 100 can be connected with a filler 200 to remove the filler 200 from the inner mold 100 after the inner mold 100 is formed and installed in the injection hole 130.

[0066] It should be noted that the above is only a preferred embodiment of the utility model and the technical principle applied. Those skilled in the art will understand that the utility model is not limited to the specific embodiments described herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the protection scope of the utility model. Therefore, although the utility model has been described in more detail through the above embodiments, the utility model is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the utility model concept. The scope of the utility model is determined by the appended claims.
