Description

Technical Field

[0001] The present invention relates to the technical field of surgical wound treatment devices, and in particular to a wound dressing spraying device. Background Art

[0002] A wound refers to the destruction of body integrity, normal anatomical structure and tissue function caused by external physical injury factors and internal factors of the body. Wound healing is essential for maintaining the physiological function of the skin. As one of the relevant means, wound dressings can quickly cover the damaged skin, maintain the moist environment and suitable temperature required for healing, and provide physical and microbial protection. Modern wound dressings mainly include hydrocolloids, alginates, hydrogels, foams and film dressings. Due to their excellent biocompatibility and biodegradability, they have become the first choice for healing various types of wounds.

[0003] Most wound dressing devices currently used are bottled sprays. When treating a wound, medical staff need to hold the outer body of the spray and press the nozzle to use a pressing mechanism connected to the nozzle to spray the dressing. This is simple and effective. However, since the dressing capacity of bottled sprays is small, they are only suitable for rapid treatment of smaller wounds. For affected areas that have been severely damaged, they need to be disinfected before dressing. The above-mentioned simple device not only has limited processing capacity, but also does not have a disinfection function, and cannot achieve rapid dressing treatment of the affected wound. Summary of the invention

[0004] The purpose of the present invention is to provide a wound dressing spray device, which is different from the traditional barrel-shaped spray structure. It is based on an annular liquid medicine ring and uses a partition plate to divide the liquid medicine ring into two different cavities, which can hold disinfectant liquid medicine and dressing liquid medicine. It is based on the annular structure of the inner solid ring and is used in conjunction with the inner soft cover assembly and the dual-purpose spray assembly. It can not only be conveniently worn on the wrist of medical staff to free the hands of medical staff, but also can spray disinfectant liquid medicine or dressing liquid medicine separately. In conjunction with the locking of the position holding component by the first locking component and the release of the first locking component by the inner soft cover assembly, the real-time rotation position of the liquid medicine ring can also be adjusted to ensure uniform spraying of liquid medicine in different cavities in the liquid medicine ring.

[0005] The object of the present invention is achieved through such a technical solution. A wound dressing spraying device includes a collar component, a position holding component, an inner soft sleeve assembly, a double pressurizing component, a dual-purpose spray assembly and a first locking component. The collar component includes an inner fixed ring, a liquid medicine ring, an inner fixed large gear and a partition plate. The position holding component includes a rotating gear. The inner soft sleeve assembly includes an inner inflatable soft sleeve and a micro air pump. The dual-purpose spray assembly includes a medicine dispensing valve, a dual-purpose integrated pipe, an atomizing nozzle and an inter-sealing inclined surface. The first locking component includes a sliding seat and a first locking tooth.

[0006] The inner ring of the medicine liquid ring is screwed to the outer ring of the inner fixed ring, the inner fixed large gear is fixed to the inner ring of the medicine liquid ring, and the inner cavity of the medicine liquid ring is divided into two cavities by a partition plate;

[0007] The rotating gear is located in the inner cavity of the inner fixed ring and meshes with the inner fixed large gear. The outer ring of the inner inflatable soft sleeve is fixedly connected to the inner ring of the inner fixed ring. A micro air pump can be used for inflation and deflation. The micro air pump can also inflate and pressurize the two cavities separated by the partition plate in the liquid medicine ring through a double pressurizing component.

[0008] The two cavities separated by the partition plate in the medicine liquid ring are both provided with internal medicine suction elbows, a medicine liquid partition is fixed inside the dual-purpose integrated tube, the inlets of different cavities in the dual-purpose integrated tube separated by the medicine liquid partition are respectively connected to the outlets of different internal medicine suction elbows through medicine outlet valves, the mutual sealing slope is provided at one end of the outlet of the dual-purpose integrated tube, the inlet of the atomizing nozzle is connected to the outlet of the dual-purpose integrated tube, and a soft sealing sleeve is also provided at the inner bottom of the dual-purpose integrated tube, and the inner end of the soft sealing sleeve is fixedly connected to the medicine liquid partition;

[0009] The slide is fixed in the inner cavity of the inner fixed ring, the first locking tooth slides in the slide in the direction of the rotating gear, an air cavity is fixedly installed on the other side of the slide, a pneumatic piston is slidably connected in the air cavity, and the end of the first locking tooth is fixedly connected to the pneumatic piston, and the air cavity is connected to the air path of the micro air pump.

[0010] The use process of the technical solution of the present invention is as follows:

[0011] The inner inflatable soft sleeve is sleeved on the wrist of the medical staff, and the inner inflatable soft sleeve can be inflated and deflated by using a micro air pump, so that after the inner inflatable soft sleeve is inflated, it is wrapped and fixed on the wrist of the medical staff;

[0012] The micro air pump can also inflate and pressurize the two different cavities separated by the partition plate of the liquid medicine ring through the dual pressurizing component, so that after opening different medicine outlet valves, the disinfectant liquid or dressing liquid in the two different cavities separated by the partition plate of the liquid medicine ring can flow through the dual-purpose integrated pipe and spray out from the atomizing nozzle, forming an operation process of first disinfecting and then dressing the patient's wound;

[0013] When the disinfectant liquid or the dressing liquid flows into the atomizing nozzle through the outlet of the dual-purpose integrated tube, the pressure will push the soft sealing sleeve to move to the other side, so that the soft sealing sleeve seals the outlet end of the other side of the cavity separated by the liquid partition in the dual-purpose integrated tube, thereby preventing the disinfectant liquid and the dressing liquid from forming an undesirable mixture at the outlet end of the dual-purpose integrated tube;

[0014] Furthermore, since the wrist of the medical staff is in an active state, this state will cause the medicine in different cavities in the medicine liquid ring to tilt. When the medicine liquid is less, the inlet end of the internal medicine suction elbow is easily exposed outside the medicine liquid. In order to eliminate this phenomenon, the device adopts a method of screwing the inner ring of the medicine liquid ring with the outer ring of the rotating gear, and the cooperation formed by the automatically rotating rotating gear and the inner solid large gear fixed in the inner ring of the medicine liquid ring can drive the medicine liquid ring to rotate relative to the inner solid ring within a certain range, so that when the wrist of the medical staff is in an active state, the internal medicine suction elbow can still evenly absorb the medicine liquid in the inner cavity of the medicine liquid ring;

[0015] When it is necessary to rotate the medicine liquid ring relative to the inner fixed ring, the air cavity is first inflated by a micro air pump, which can push the pneumatic piston and the first locking tooth to overcome the elastic force of the first locking tooth itself and move in the direction away from the rotating gear, thereby contacting the locking state of the first locking tooth on the rotating gear. The purpose is to keep the medicine liquid ring in the current rotation position by locking the rotating gear and the rotation position of the inner fixed large gear by the first locking tooth when the medicine liquid ring is in the non-rotating state.

[0016] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0017] (1) The device is annular in structure and can be conveniently worn on the wrist of medical staff. The annular liquid ring is used as a chamber, and a partition plate is used to separate the liquid ring into two different chambers, which can respectively hold the dressing liquid and the disinfectant liquid;

[0018] (2) In order to simultaneously realize the convenience, comfort and stability of the device when worn by medical staff, the present invention has an inner inflatable soft sleeve fixedly installed in the inner ring of the inner fixed ring, and the inner inflatable soft sleeve can be inflated and deflated by a micro air pump; and at the same time, the micro air pump can also be used to inflate and pressurize the interior of the medicine liquid ring into two different cavities by dividing the medicine liquid ring into two different cavities, thereby pressurizing the medicine liquid contained in the medicine liquid ring so that it can be automatically sprayed out during subsequent operations;

[0019] (3) The end of the first locking tooth that is elastically moved toward the rotating gear is also fixedly connected to the pneumatic piston. The purpose is not only to make the first locking tooth in a position to lock the rotating gear and the inner fixed large gear in a non-operating state, so that the medicine liquid ring can be in a stable rotational stop position relative to the inner fixed ring, but also to make it possible to release the locking of the first locking tooth on the rotating gear by inflating the air cavity by the inner inflatable soft sleeve when the rotational position of the medicine liquid ring needs to be adjusted;

[0020] (4) In order to improve the convenience of use for medical staff, the two different liquid medicines contained in the liquid medicine ring of the present invention can share the dual-purpose integrated tube and the atomizing nozzle, and the dual-purpose integrated tube is divided into two different cavities by a liquid medicine partition, the purpose of which is to be connected with different cavities in the liquid medicine ring respectively, and a mutually sealing inclined surface is creatively opened at the outlet end of the dual-purpose integrated tube, and a soft sealing sleeve is fixedly connected to the inner bottom end of the mutually sealing inclined surface, so that when the liquid medicine passes through the cavity on one side of the dual-purpose integrated tube, the soft sealing sleeve can be pushed to seal the outlet end of the cavity on the other side of the dual-purpose integrated tube at the same time, so that different liquid medicines in different cavities in the dual-purpose integrated tube will not be mixed at the outlet end of the dual-purpose integrated tube and the inlet end of the atomizing nozzle.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0047] like Figure 1-Figure 15 As shown, a wound dressing spraying device, the inner ring of the liquid medicine ring 104 in the collar member is screwed to the outer ring of the inner fixed ring 101, the inner fixed large gear 105 is fixed to the inner ring of the liquid medicine ring 104, and will not interfere with the rotation of the liquid medicine ring 104 relative to the inner fixed ring 101, and the inner cavity of the liquid medicine ring 104 is divided into two symmetrically distributed cavities by a partition plate 109;

[0048] The automatically rotatable rotating gear 202 is located in the inner cavity of the inner fixed ring 101 and meshes with the inner fixed large gear 105. The outer ring of the inner inflatable soft sleeve 301 is fixedly connected to the inner ring of the inner fixed ring 101. The micro air pump 302 can be used for inflation and deflation. The micro air pump 302 can also inflate and pressurize the two cavities separated by the partition plate 109 in the liquid medicine ring 104 through a double pressurizing component.

[0049] In the two cavities separated by the partition plate 109 in the liquid medicine ring 104, an internal medicine suction bend pipe 502 is provided, and a liquid medicine partition plate 507 is fixed inside the dual-purpose integrated pipe 505. The inlets of different cavities in the dual-purpose integrated pipe 505 separated by the liquid medicine partition plate 507 are respectively connected to the outlets of different internal medicine suction bend pipes 502 through the medicine outlet valve 504, and the mutual sealing slope 508 is provided at one end of the outlet of the dual-purpose integrated pipe 505. The inlet of the atomizing nozzle 506 is connected to the outlet of the dual-purpose integrated pipe 505. A soft sealing sleeve 509 is also provided at the inner bottom of the dual-purpose integrated pipe 505, and the inner end of the soft sealing sleeve 509 is fixedly connected to the liquid medicine partition plate 507. After the pressurized liquid medicine flows through one group of cavities in the dual-purpose integrated pipe 505 separated by the liquid medicine partition plate 507, the pressure can synchronously push the soft sealing sleeve 509 to seal the outlet of the other group of cavities to prevent two different liquid medicines from mixing at the outlet of the dual-purpose integrated pipe 505.

[0050] The slide 601 is fixed in the inner cavity of the inner fixed ring 101, and the first locking tooth 603 is slidably connected in the slide 601 in the direction of the rotating gear 202. An air cavity 605 is fixedly installed on the other side of the slide 601, and a pneumatic piston 607 is slidably connected in the air cavity 605. The end of the first locking tooth 603 is fixedly connected to the pneumatic piston 607, and the air cavity 605 is connected to the air path of the micro air pump 302, so that the inner cavity of the air cavity 605 can be inflated and deflated.

[0051] Here’s how it works:

[0052] The two different cavities of the liquid medicine ring 104 divided by the partition plate 109 are used to contain the disinfectant liquid medicine and the dressing liquid medicine respectively. The purpose is to use the disinfectant liquid medicine to disinfect the patient's wound before dressing.

[0053] The inner inflatable soft sleeve 301 is sleeved on the wrist of the medical staff, and the inner inflatable soft sleeve 301 can be inflated and deflated by using the micro air pump 302, so that after the inner inflatable soft sleeve 301 is inflated, it can be softly wrapped and fixed on the wrist of the medical staff;

[0054] The micro air pump 302 can also inflate and pressurize the two different cavities of the liquid medicine ring 104 divided by the partition plate 109 through the dual pressurizing components, so that after opening the different medicine outlet valves 504, the disinfectant liquid or dressing liquid in the two different cavities of the liquid medicine ring 104 divided by the partition plate 109 can flow through the dual-purpose integrated tube 505 and be sprayed outward from the atomizing nozzle 506, forming an operation process of first disinfecting and then dressing the patient's wound;

[0055] When the disinfectant solution or the dressing solution flows into the atomizing nozzle 506 through the outlet of the dual-purpose integrated tube 505, the pressure will push the soft sealing sleeve 509 to move to the other side, so that the soft sealing sleeve 509 seals the outlet end of the other side of the cavity separated by the liquid partition 507 in the dual-purpose integrated tube 505, thereby preventing the disinfectant solution and the dressing solution from forming an undesirable mixture at the outlet end of the dual-purpose integrated tube 505.

[0056] Furthermore, during the operation, the wrist of the medical staff is in an active state, which may cause the liquid medicine in different cavities in the liquid medicine ring 104 to tilt. When the liquid medicine is less, the inlet end of the internal medicine suction curved tube 502 is easily exposed outside the liquid medicine. In order to eliminate this phenomenon, the device adopts a method of screwing the inner ring of the liquid medicine ring 104 with the outer ring of the rotating gear 202, and the cooperation formed by the automatically rotating rotating gear 202 and the inner fixed large gear 105 fixed in the inner ring of the liquid medicine ring 104 can drive the liquid medicine ring 104 to rotate relative to the inner fixed ring 101 within a certain range, so that when the wrist of the medical staff is in an active state, the internal medicine suction curved tube 502 can still evenly absorb the liquid medicine in the inner cavity of the liquid medicine ring 104;

[0057] When it is necessary to rotate the medicine liquid ring 104 relative to the inner fixed ring 101, the air cavity 605 is first inflated by the micro air pump 302, which can push the pneumatic piston 607 and the first locking tooth 603 to overcome the elastic force of the first locking tooth 603 itself and move in the direction away from the rotating gear 202, thereby contacting the locking state of the rotating gear 202 by the first locking tooth 603. The purpose is to lock the rotating gear 202 and the rotation position of the inner fixed large gear 105 by the first locking tooth 603 when the medicine liquid ring 104 is in a non-rotating state, so that the medicine liquid ring 104 can be maintained in the current rotation position.

[0058] The specific structure of the collar member and the position holding member is as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the ring cover 102 covers the opening on one side of the inner solid ring 101, and the air drive chamber 103 is fixedly connected to one side of the main body of the ring cover 102, and will not interfere with the rotation of the liquid medicine ring 104 relative to the inner solid ring 101;

[0059] A medicine adding seat 106 is connected and fixed to the top of the outer side surface of the medicine liquid ring 104, and a partition plate 109 enters the inner cavity of the medicine liquid ring 104 from the medicine adding seat 106 to separate the medicine liquid ring 104 into two different cavities;

[0060] The outer cover 107 is threadedly connected to the medicine adding seat 106, and a separation sealing ring 110 is fixedly installed on the top of the medicine adding seat 106 and the partition plate 109. After the outer cover 107 is put on the medicine adding seat 106, the inner bottom surface of the outer cover 107 squeezes the separation sealing ring 110, so as to achieve the effect of completely sealing and isolating the two different cavities in the medicine liquid ring 104;

[0061] A gyro sensor 108 is fixedly mounted on the bottom end of the outer side of the liquid medicine ring 104, and the mounting position of the gyro sensor 108 is directly opposite to the partition plate 109. A lithium battery 111 and a main control board 112 are fixedly mounted in the inner cavity of the inner fixed ring 101, and the lithium battery 111 and the main control board 112 are electrically connected, and the gyro sensor 108 and the main control board 112 are electrically connected.

[0062] The rotation position of the medicine liquid ring 104 can be sensed in real time by the gyro sensor 108, and a signal is sent to the main control board 112, so that after the medical staff fixes the device to the wrist, no matter how the medical staff rotates the wrist, the medicine liquid ring 104 can be adjusted relative to the inner fixed ring 101 to keep the medicine liquid ring 104 in the upward position of the medicine adding seat 106. Since the inlet end of the internal medicine suction elbow 502 is located at the bottom end of the cavity of the medicine liquid ring 104, when the medicine liquid ring 104 is located at the upward position of the medicine adding seat 106, the medicine liquid in the inner cavity of the medicine liquid ring 104 is relatively sufficient, and the situation of interruption of the medicine liquid spraying during use will not occur;

[0063] The rotating motor 201 is fixedly installed in the inner cavity of the inner fixed ring 101 and is electrically connected to the main control board 112. The rotating gear 202 is inserted and fixed in the rotating shaft of the rotating motor 201. A clearance groove 203 is opened on the outer side of the inner fixed ring 101. The rotating gear 202 passes through the clearance groove 203 and meshes with the inner fixed large gear 105.

[0064] In order to further improve the stability of the rotation of the liquid medicine ring 104 relative to the inner solid ring 101 and the smoothness of the cooperation between the rotating gear 202 and the inner solid large gear 105, a plurality of rotating gears 202 can be evenly arranged in the inner cavity of the inner solid ring 101, wherein one group of rotating gears 202 is plugged and fixed in the rotating shaft of the rotating motor 201 and is in an active rotating state, and the other at least two groups of rotating gears 202 are in a free rotating state in the inner solid ring 101 and are meshed with the inner solid large gear 105;

[0065] After the main control board 112 receives the signal for adjusting the rotation position of the medicine liquid ring 104, the micro air pump 302 is automatically started to inflate the inner cavity of the air cavity 605 first, pushing the pneumatic piston 607 and the first locking tooth 603 to move away from the rotating gear 202, so that the rotating gear 202 is in a free rotation state, and then the rotating motor 201 is started to drive the rotating gear 202 to form a matching transmission with the inner fixed large gear 105, thereby driving the medicine liquid ring 104 to rotate relative to the inner fixed ring 101, and adjusting the medicine liquid ring 104 to a suitable rotation position in real time.

[0066] The specific structure of the inner soft cover assembly is as follows: Figure 7 and Figure 8 As shown, the micro air pump 302 is fixedly installed in the inner cavity of the air drive cavity 103, the air inlet end of the air outlet tee 304 is connected to the air outlet end of the micro air pump 302, one side of the air outlet end of the air outlet tee 304 is connected to the outside of the inner inflatable soft sleeve 301 through the inflatable connecting pipe 305, and the other side of the air outlet end of the air outlet tee 304 is connected to the double pressurizing component;

[0067] The outside of the inner inflatable soft sleeve 301 is also connected to a first exhaust pipe 308, a first exhaust valve 309 is installed in the main pipe of the first exhaust pipe 308, an exhaust hole 303 is opened in the body of the inner inflatable soft sleeve 301, and the outlet end of the first exhaust pipe 308 is connected to the exhaust hole 303;

[0068] An inflation valve 307 is also installed in the main pipeline of the inflation tube 305, and the locking tube 306 is connected to the inflation tube 305, and the inflation valve 307 is located outside the control range of the locking tube 306, that is, the inflation valve 307 can only control the micro air pump 302 to inflate the inner inflatable soft sleeve 301 through the inflation tube 305, and cannot control the inflation of the locking tube 306;

[0069] The outlet end of the inflatable connecting pipe 305 passes through the side wall of the inner solid ring 101 and is connected to the outside of the inner inflatable soft sleeve 301. The inlet end of the first exhaust pipe 308 passes through the side wall of the inner solid ring 101 and is connected to the outside of the inner inflatable soft sleeve 301.

[0070] The micro air pump 302, the inflation valve 307 and the first exhaust valve 309 are all electrically connected to the main control board 112;

[0071] After the inner inflatable soft sleeve 301 is sleeved on the wrist of the medical staff, the micro air pump 302 can be started and the inflation valve 307 can be opened through the main control panel 112 when the first exhaust valve 309 is closed, and the inner inflatable soft sleeve 301 can be inflated so that the inner inflatable soft sleeve 301 is inflated to form a flexible wrapping fixation on the outside of the medical staff. After the inflation is completed, the inflation valve 307 can be closed;

[0072] When the device needs to be removed, the first exhaust valve 309 is opened.

[0073] The specific structure of the double pressure component is as follows: Fig. 9 As shown, the inlet end of the pressurizing tee 401 passes through the side wall of the air drive chamber 103 and is connected to the other side outlet end of the air outlet tee 304;

[0074] A ring body connection seat 402 is symmetrically connected and fixed to one side of the side wall of the liquid medicine ring 104, and a pressure sensing valve 403 is installed in each group of the ring body connection seat 402. The outlet ends on both sides of the pressurizing tee 401 are connected to the pressure sensing valve 403 through the pressure inlet connecting pipe 405 respectively, and a pressure inlet valve 404 is also installed in the main pipe of each group of the pressure inlet connecting pipe 405;

[0075] The pressure sensing valve 403 and the pressure inlet valve 404 are both electrically connected to the main control board 112;

[0076] When only the pressure inlet valve 404 is in the open position, the micro air pump 302 can be started by the main control board 112 to inflate and pressurize the two different cavities in the liquid medicine ring 104. The pressure sensing valve 403 can monitor the gas pressure filled into the cavity of the liquid medicine ring 104 in real time. When the set value is reached, the pressure inlet valve 404 and the micro air pump 302 will be automatically closed.

[0077] Furthermore, the pressure inlet connecting pipe 405 is made of a hose with a certain length, which will not affect the rotation process of the liquid medicine ring 104 relative to the inner fixed ring 101 .
