For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] Trauma is unavoidable during outdoor activities or field activities. In order to ensure the safety of life and property, people usually carry hemostatic kits. However, hemostatic kits are only used to apply to the surface of the skin and cannot be used to treat deeper wounds, so the treatment is very limited.

[0042] In view of this, the designer designed a trauma hemostatic dressing introduction device, which can not only perform hemostatic treatment on the skin surface, but also can treat deeper wounds. It is flexible and versatile in use, suitable for use in various scenarios, and has good hemostatic effect.

[0043] See also Figure 1-Figure 8 In this embodiment, the trauma hemostatic dressing introduction device includes a base 100 and a push mechanism 300. The base 100 is provided with an injection needle hole 101 and a plurality of drug storage channels 102. The plurality of drug storage channels 102 are evenly spaced around a preset axis, and the plurality of drug storage channels 102 are connected to the injection needle hole 101. Each drug storage channel 102 is provided with a diaphragm 140 that can be broken under the action of an external force. The push mechanism 300 is movably connected to the base 100. The push mechanism 300 can move relative to the base 100 to selectively correspond to one of the plurality of drug storage channels 102, and can cause the medicine in the corresponding drug storage channel 102 to break the diaphragm 140, so that the medicine is ejected from the injection needle hole 101.

[0044] In this embodiment, the use of the trauma hemostatic dressing introduction device is as follows:

[0045] First, operate the push injection mechanism 300 to make it cooperate with one of the multiple drug storage channels 102, then align the injection needle hole 101 with the position to be treated, and make the injection needle hole 101 below the skin. After the position adjustment of the injection needle hole 101 is completed, apply force to the push injection mechanism 300 to make the push injection mechanism 300 move relative to the base 100, so that the medicine in the drug storage channel 102 first breaks through the diaphragm 140 under pressure, and then enters the injection needle hole 101, and finally is discharged from the injection needle hole 101. The whole operation process is convenient and fast, and the injection needle hole 101 can be outside the skin or below the skin, and the covering method of the medicine is diverse, which can adapt to the hemostasis treatment of deeper wounds and has a wide range of uses. At the same time, there are multiple drug storage channels 102, and the multiple drug storage channels 102 can store medicines, which can be used multiple times, saving costs. The medicines in each drug storage channel 102 are placed independently without interfering with each other, which is environmentally friendly and hygienic.

[0046] It should be understood that, in order to ensure that the push injection mechanism 300 is aligned with one of the multiple drug storage channels 102, a first identification portion is provided on the push injection mechanism 300, and multiple second identification portions are provided on the base 100, and the multiple second identification portions are evenly spaced and arranged in the circumferential direction of the preset axis, and each second identification portion is aligned with a drug storage channel 102. When adjusting the push injection mechanism 300, the first identification portion on the push injection mechanism 300 can be aligned with one of the multiple second identification portions, and the adjustment is flexible and convenient. For example, in this embodiment, the number of drug storage channels 102 is four, and correspondingly, the base 100 has four second identification portions.

[0047] In this embodiment, the push injection mechanism 300 optionally includes a force-applying unit 310 and a plurality of force-transmitting units 330, wherein the force-applying unit 310 is movably connected to the base 100; the plurality of force-transmitting units 330 are respectively disposed in the plurality of drug storage channels 102, and the force-applying unit 310 is used to cooperate with one of the plurality of force-transmitting units 330, so as to discharge the medicine in the corresponding drug storage channel 102 out of the injection needle hole 101 through the force-transmitting unit 330. In addition, the first identification portion is disposed on the force-applying unit 310, that is, when the medicine needs to be pushed, the position of the force-applying unit 310 is first adjusted through the first identification portion so that it is aligned with a second identification portion, that is, aligned with the force-transmitting unit 330 located in the corresponding drug storage channel 102, and force is applied to the force-applying unit 310, which can drive the force-transmitting unit 330 to move, so that the medicine is ejected from the injection needle hole 101.

[0048] It should be understood that part or all of the base 100 may be set as a light-transmitting member, so that the condition of the medicine in the medicine storage channel 102 can be observed from the outside of the base 100 to determine whether the injection is complete or whether it has been used.

[0049] In addition, a pre-rupture groove may be provided on the diaphragm 140. When external force is transmitted to the medicine in the medicine storage channel 102 through the force transmission unit 330, the medicine acts on the diaphragm 140, and the pre-rupture groove has low strength and is easily broken.

[0050] In this embodiment, optionally, the base 100 includes a cylindrical body 110, a circular outer cylinder 120 and a circular inner cylinder 130, and the injection needle hole 101 and a plurality of drug storage channels 102 are all arranged on the body 110. Moreover, each drug storage channel 102 is connected with the injection needle hole 101 through an elongated channel, and the diaphragm 140 is arranged in the elongated channel, so as to facilitate the drug to break the diaphragm 140. Moreover, a one-way valve is arranged in each elongated channel, and the diaphragm 140 is located on the side of the one-way valve away from the injection needle hole 101, that is, the drug can only flow in the direction of the diaphragm 140, the one-way valve and the injection needle hole 101, so as to avoid the drug backflow; and also to avoid the drug backflow to the remaining drug storage channels 102 and the remaining diaphragms 140 when the drug in one of the drug storage channels 102 is pushed.

[0051] Meanwhile, both ends of the outer tube 120 and the inner tube 130 are open, one end of the outer tube 120 is connected to the body 110, one end of the inner tube 130 is connected to the body 110, the inner tube 130 is arranged in the area surrounded by the outer tube 120, the inner tube 130 and the outer tube 120 jointly define an annular space 103, and the inner tube 130, the outer tube 120 and the body 110 are arranged coaxially. The ends of the multiple drug storage channels 102 away from the injection needle hole 101 are all located between the inner tube 130 and the outer tube 120, and the ends of the drug storage channels 102 away from the injection needle hole 101 are provided with a sealing film 150, and the force transmission unit 330 is located between the sealing film 150 and the diaphragm 140. The medicine is located between the force transmission unit 330 and the diaphragm 140. By providing the sealing film 150 , a relatively closed space is formed between the sealing film 150 and the diaphragm 140 . The medicine is placed in the closed space, is not easily contaminated, has a long shelf life, and is highly safe to use.

[0052] Optionally, the force applying unit 310 is rotatably connected to the outer tube 120 and the inner tube 130 around a preset axis. When the force applying unit 310 rotates relative to the base 100, the force applying unit 310 can be rotated to a position corresponding to one of the plurality of drug storage channels 102 under the guidance of the first identification portion and the second identification portion, thereby transmitting the external force to the force transmission unit 330. It should be understood that the second identification portion can be provided on the outer tube 120 or the body 110, etc.

[0053] Furthermore, the drug storage channel 102 has a connected circular segment 1021 and an elliptical segment 1022, the end of the circular segment 1021 away from the elliptical segment 1022 is connected to the annular space 103, and the elliptical segment 1022 is connected to the injection needle hole 101 through a slender channel, that is, the circular segment 1021 is located on the side of the elliptical segment 1022 away from the injection needle hole 101.

[0055] Specifically, the first identification portion is provided on the turntable 311. The turntable 311 is provided with a first mounting hole 3111 and a second mounting hole 3112, both of which are round holes. The turntable 311 covers one end of the outer cylinder 120 away from the body 110 and is rotatably connected to the outer cylinder 120 around a preset axis. For example, the turntable 311 can be rotatably connected to the outer cylinder 120 through a ball bearing. The first mounting hole 3111 on the turntable 311 is connected to the annular space 103, and the second mounting hole 3112 is connected to the inner cylinder 130. The second mounting hole 3112, the outer cylinder 120 and the inner cylinder 130 are coaxially arranged.

The knife body 313 is slidably connected to the first guide hole 3121 in the extension direction of the preset axis, and the knife body 313 and the force rod 312 are relatively fixed in the circumferential direction of the axis of the first guide hole 3121, that is, the force rod 312 can drive the knife body 313 to rotate together, and the knife body 313 itself can slide relative to the force rod 312 in the extension direction of the preset axis. One end of the first elastic member 314 abuts against the blade body 313 , and the other end abuts against the base 100 , so as to make the blade body 313 move away from the medicine storage channel 102 ; the first force transmission head 315 is provided with a guiding slope 3151 , and the first force transmission head 315 is connected to the blade body 313 .

[0056] For example, in this embodiment, the matching structure of the blade body 313 and the force application rod 312 can be as follows:

[0057] The first elastic member 314 is configured as a spring, and the first elastic member 314 is sleeved on the outside of the blade body 313.

The blade body 313 passes through the second baffle 321 in the extension direction of the preset axis, and can slide and rotate relative to the second baffle 321. Meanwhile, when the rotating disk 311 is rotated, the blade 313 can drive the second baffle 321 to rotate around a preset axis in the annular space 103. The first elastic member 314 is clamped between the first baffle 320 and the second baffle 321 to make the blade 313 move away from the diaphragm 140.

When the rotating disk 311 drives the force rod 312 to move to a position corresponding to the drug storage channel 102, the second guide hole 3122 is connected to the third guide hole 3161 through a corresponding communication hole 131. Under the action of external force, the positioning rod 317 can drive the positioning cam 318 to rotate, so as to push the second force transmission head 319 through the connecting hole 131 and the second guide hole 3122 and enter the first guide hole 3121 through the positioning cam 318, so that the second guide cone surface 3192 of the second force transmission head 319 is abutted against the guide slope 3151, and drive the blade body 313 to approach the drug storage channel 102, so that the blade body 313 can pierce the sealing film 150 in the corresponding drug storage channel 102 and drive the force transmission unit 330 to move.

[0061] Further, a first bearing is provided in the first mounting hole 3111, and the force-applying rod 312 is inserted into the first bearing and rotatably connected to the rotating disk 311. The force transmission unit 330 includes a force transmission seat 331, a force transmission sleeve 332, a piston 333 and a force transmission rod 334. The force transmission seat 331 is provided with a card slot 3311, and the force transmission seat 331 is rotatably connected to the circular segment 1021 of the drug storage channel 102 through a second bearing, and the two are relatively fixed in the extension direction of the preset axis, that is, the force transmission seat 331 can rotate relative to the drug storage channel 102 but cannot slide relative thereto. The notch of the card slot 3311 is located near the sealing film 150 and is connected to the drug storage channel 102; the force transmission sleeve 332 is provided with a threaded hole, and the force transmission sleeve 332 is fixedly connected to the force transmission seat 331, and one end of the threaded hole is located on the side of the force transmission seat 331 away from the sealing film 150 and is connected to the drug storage channel 102. The piston 333 is connected to the force transmission rod 334, and the force transmission rod 334 is screwed to the threaded hole. The piston 333 is slidably connected to the elliptical section 1022 of the medicine storage channel 102 and the two are relatively fixed in the circumferential direction of the medicine storage channel 102. The blade body 313 can be inserted into the slot 3311 after piercing the sealing film 150 under the drive of the second force transmission head 319, so that the force transmission seat 331 is driven to rotate through the blade body 313. When the force transmission seat 331 rotates, since the force transmission seat 331 will not move along the extension direction of the preset axis relative to the medicine storage channel 102, the force transmission seat 331 drives the guide sleeve 370 to rotate, and the guide rod is connected to the piston 333 and will not rotate relative to the medicine storage channel 102. In this way, the guide rod can drive the piston 333 to slide back and forth in the extension direction of the preset axis, thereby realizing the push injection of the medicine.

[0062] Further, a slider 325 is provided on the blade body 313, and a slideway 3123 is provided on the hole wall of the first guide hole 3121. The slider 325 is slidably connected to the slideway 3123 in the extension direction of the preset axis, and the slider 325 and the force rod 312 are relatively fixed in the circumferential direction of the first guide hole 3121. That is to say, through the cooperation of the slider 325 and the slideway 3123, the blade body 313 is guided to slide along the preset axis relative to the force rod 312, and will not rotate relative to the force rod 312. Of course, the slider 325 can be provided on the first force transmission head 315. Alternatively, the first force transmission head 315, the slider 325 and the blade body 313 are integrally formed. Moreover, under the action of the first elastic member 314, the slider 325 maintains abutment with a groove wall of the slideway 3123 away from the drug storage channel 102, and the groove wall is substantially flush with the bottom wall of the first guide hole 3121.

[0063] In this embodiment, optionally, the force-applying unit 310 also includes a second elastic member 350, a guide sleeve 370 and a guide column 390. The guide sleeve 370 is connected to the positioning block 316 and is located in the third guide hole 3161. The guide column 390 is connected to the positioning rod 317. The guide column 390 is inserted into the guide sleeve 370 and can slide and rotate relative to the guide sleeve 370. The second elastic member 350 is arranged in the guide sleeve 370 to make the guide column 390 have a sliding tendency away from the guide sleeve 370. The fourth guide hole 3162 is provided with a guide slot 3163 and a limiting slot 3164 on the hole wall, the guide slot 3163 extends along the preset axis, the limiting slot 3164 extends around the preset axis, and the guide slot 3163 is connected to the guide slot 3163; the positioning rod 317 is provided with a limiting protrusion 322, and the limiting protrusion 322 is slidably connected to the guide slot 3163 or the limiting slot 3164; when the limiting protrusion 322 is located in the limiting slot 3164 and has a spacing with the guide slot 3163 in the circumferential direction of the preset axis, the positioning rod 317 and the positioning block 316 are relatively fixed in the extending direction of the preset axis. It should be understood that the second elastic member 350 can be a spring, a spring sheet or a rubber member.

[0064] Furthermore, a rubber baffle 323 and a baffle ring 324 are provided in the third guide hole 3161. The baffle ring 324 is located on the side of the rubber baffle 323 away from the wall of the inner tube 130. The rubber baffle 323 and the baffle ring 324 prevent the second force transmission head 319 from sliding freely in the third guide hole 3161 when it is in the third guide hole 3161, thereby preventing it from sliding out of the third guide hole 3161 and entering the annular space 103. When the second force transmission head 319 is pushed toward the first guide hole 3121 by the positioning cam, the second force transmission head 319 can pass over the rubber baffle 323. Similarly, when the second force transmission head 319 returns from the first guide hole 3121 to the third guide hole 3161, the second force transmission head 319 can also pass over the rubber baffle 323.

[0065] The use process of the trauma hemostatic dressing introduction device provided in this embodiment is as follows:

[0066] Please combine Figure 1 and Figure 8 , set, in the initial state, the blade body 313 is aligned with a medicine storage channel 102. In addition, a third identification portion is provided on the force rod 312. When the first identification portion, the second identification portion and the third identification portion are aligned, the blade body 313 is aligned with the medicine storage channel 102, and the third guide hole 3161 is connected with the first guide hole 3121 through a connecting hole 131. At this time, first press the positioning rod 317 to move it downward for a distance, so that the limiting protrusion 322 on the positioning rod 317 slides in the guide slot 3163 and slides to the connection position of the guide slot 3163 and the limiting slot 3164. At this time, the side with a smaller radius of the positioning cam is in contact with one end face of the second force transmission head 319. In this process, the second elastic member 350 is compressed. Then, the positioning rod 317 is rotated to drive the limiting protrusion 322 and the positioning cam to rotate, and the limiting protrusion 322 is engaged in the limiting sliding groove 3164, and the positioning cam drives the second force transmission head 319 to move toward the connecting hole 131 and move to the first guide hole 3121. Due to the structural limitation of the positioning cam, the second force transmission head 319 does not completely enter the first guide hole 3121, but a small part is located in the connecting hole 131 and the second guide hole 3122. At this time, the second guide cone surface 3192 on the second force transmission head 319 abuts against the hole walls of the connecting hole 131 and the second guide hole 3122. When the second force transmission head 319 enters the first guide hole 3121, the first guide cone surface 3191 abuts against the guiding inclined surface 3151, so that the blade body 313 is driven to approach the sealing film 150 through the first force transmission head 315, and the blade body 313 pierces the sealing film 150 and then inserts into the card slot 3311. At this time, the force applying rod 312 is rotated again. Since the second guiding inclined surface 3151 of the second force transmitting head 319 contacts the hole wall of the connecting hole 131 and the second guide hole 3122, when the torque is transmitted to the second force transmitting head 319 through the force applying rod 312, most of the second force transmitting head 319 can enter the first guide hole 3121, and a small part is located in the second guide hole 3122, and the second force transmitting head 319 can continuously press the first force transmitting head 315, so that the blade 313 is always inserted in the card slot 3311, so that the blade body 313 can smoothly drive the force transmitting seat 331 to rotate together, so as to utilize the cooperation of the force transmitting seat 331, the force transmitting sleeve 332 and the force transmitting rod 334 to push the piston 333, so that the piston 333 pushes the medicine, and the diaphragm 140 is broken by the medicine and ejected from the injection needle hole 101, thereby completing a medicine injection.

[0067] Then, the force rod 312 is rotated at a minimum angle to align the third identification portion with the first identification portion (obviously, if the third identification portion is just aligned with the first identification portion when the injection is completed, there is no need to rotate the force rod 312). At this time, the first guide hole 3121, the connecting hole 131 and the third guide hole 3161 are in a connected state, and the positioning rod 317 is rotated in the opposite direction to make it slide out of the limiting slide groove 3164, and under the action of the second elastic member 350, it is restored to the position where the limiting protrusion 322 is located in the guide slide groove 3163. At this time, the positioning cam will not block the position where the third guide hole 3161 and the connecting hole 131 are connected. Under the action of the first elastic member 314, the blade 313 and the first force transmission head 315 are reset, pushing the second force transmission head 319 into the third guide hole 3161, and the force unit 310 completes the reset action, and the injection of the medicine in the next medicine storage channel 102 can be carried out.

[0068] The trauma hemostatic dressing introduction device provided in this embodiment is convenient and reliable to use, can be used multiple times, and has a wide range of applications; at the same time, it has an anti-accidental touch function and is safe and reliable.

[0069] It should be understood that after the injection is completed, an end cap can be connected to the injection needle hole 101.

[0070] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
