Description

Technical Field

[0001] The invention relates to the technical field of protective masks, and in particular to an isolation protective mask. Background Art

[0002] During some surgical operations, in order to prevent infection of human tissue and droplets, doctors need to wear isolation protective masks to protect the head and neck of personnel. Currently, the isolation protective masks wrapped around the head are wrapped and protected by being set on the outside of the head of the personnel. During long surgical operations, sweat will slide down the head of the wearer, and the sweat will flow down the forehead into the eyes of the personnel, causing eye discomfort and affecting the wearer's vision, thereby affecting the wearer's surgical operations. In this process, due to the obstruction of the isolation protective mask, the assistant nurse cannot wipe the sweat for the wearer through the isolation protective mask, and the isolation protective mask cannot handle the problem of the wearer's sweat sliding into the eyes by itself. For this reason, we propose an isolation protective mask. Summary of the invention

[0003] The main purpose of the present invention is to provide a kind of isolation protection mask.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A further improvement of the present invention is that a binding and tightening belt which plays a fixing role is fixedly connected to the bottom end of the inner support helmet.

[0007] A further improvement of the present invention is that a clearance groove is provided on the sliding connection plate, and a flip pulling plate having a limiting function is hingedly connected to the end of the guide sliding block.

[0008] A further improvement of the present invention is that a guide slot is provided on the track arc plate, and the guide slider is slidably connected to the inner wall of the guide slot.

[0009] A further improvement of the present invention is that both ends of the track arc plate are fixedly connected to the limit frame plate, the elastic sweat-absorbing cotton block is stored in the limit frame plate, and the side wall of the limit frame plate is fixedly connected with a protective cotton pad.

[0010] A further improvement of the present invention is that both ends of the two traction ropes are equipped with electric winding rollers, and the end of the guide slider is fixedly connected with a flip limit plate.

[0011] A further improvement of the present invention is that a control button is installed on the top of the control panel, and an elastic extrusion plate is hinged on the top of the control panel, and the elastic extrusion plate covers the top of the control button. A connecting wire is fixedly connected to one side of the control panel, and the control panel is electrically connected to the electric winding roller through the connecting wire.

[0012] A further improvement of the present invention is that a protective mask for isolation comprises:

[0013] Wearing stage:

[0014] The three elastic sweat-absorbing cotton blocks are all stored in the limit frame plate. The elastic sweat-absorbing cotton blocks are in a compressed state. After wearing the mask, the staff wears the inner support helmet on the top of the head, and the binding belt is tied to the chin of the user. Then the staff glues the control panel to the user's shoulder near the neck. Then the staff sets the protective mask head cover and the protective mask transparent plate on the top of the inner support helmet. The protective mask transparent plate corresponds to the facial position of the user. The lower part of the protective mask head cover falls on the chest position of the user. The staff wears the surgical protective suit and wraps the lower part of the protective mask head cover in the surgical protective suit.

[0015] Use phase:

[0016] The staff performs the surgical operation normally. When there is no need to wipe sweat, the protective mask hood and the protective mask transparent plate worn by the staff use the basic functions of the protective mask. The protective mask hood and the protective mask transparent plate protect the head and neck of the user, and the head and neck of the user will not be contaminated by external tissue splashes and droplets. When it is necessary to wipe sweat, the user's head tilts at a large angle toward the shoulder position where the control panel is installed, and uses the head to squeeze the elastic squeezing plate, and squeezes the control button on the top of the control panel through the elastic squeezing plate to transmit an electrical signal to the electric winding roller, control one of the electric winding rollers to start, and reel the traction rope through the winding roller on the electric winding roller, and the traction guide slider moves along the trajectory of the track arc plate, and the guide slider drives the sliding connecting plate and the elastic sweat-absorbing cotton block to move synchronously, and the elastic sweat-absorbing cotton block is separated from the limit frame plate. The elastic sweat-absorbing cotton block then unfolds under its own elastic force, contacts along the user's forehead skin, and wipes the sweat on the user's forehead during the movement of the elastic sweat-absorbing cotton block until the elastic sweat-absorbing cotton block moves into the limit frame plate on the other side, and then another electric winding roller starts to wind up the traction rope, driving the guide slider and the flip traction plate to reset, and the flip traction plate rotates under the squeezing of the sliding connection plate and is pulled out from the yielding slot, so that the flip traction plate is out of contact with the sliding connection plate, and the guide slider and the flip traction plate move further until the flip traction plate moves to the unused sliding connection plate, the flip traction plate is squeezed and flipped, and passes through the yielding slot to wait for the next use, and the three elastic sweat-absorbing cotton blocks can provide the user with three sweat wiping operations to prevent sweat from dripping into the user's eyes, so that the staff can complete the surgical operation stably;

[0017] Cleaning phase:

[0018] After the operation is completed, the staff removes the device from the head, then removes the elastic sweat-absorbent cotton block from the sliding connecting plate, cleans and disinfects the device, and glues a new elastic sweat-absorbent cotton block to the sliding connecting plate. The staff then adjusts the sliding connecting plate and the elastic sweat-absorbent cotton block to their original position through the controller, and packages the device for storage for next use.

[0019] Compared with existing technologies:

[0020] By means of a traction rope driving the guide slider to reciprocate along the trajectory of the track arc plate, three elastic sweat-absorbing cotton blocks can be driven to move in accordance with the forehead skin of the user in batches, so as to wipe the sweat on the forehead of the user multiple times, thereby preventing the sweat on the forehead from dripping into the eyes of the user, so that the staff can complete the surgical operation stably. With the help of a control panel installed on the shoulders of the staff, the staff can control the wiping of sweat on the forehead of the user by the elastic sweat-absorbing cotton blocks through head movement, without occupying the hands of the user, and the operation is more convenient and safe.

[0028] Example 1

[0029] See also Figure 1-5 ,

[0030] The present invention provides the following technical solutions: a protective mask for isolation, comprising a protective mask head cover 1 and a protective mask transparent plate 11, an inner support helmet 2 is arranged on the outer side of the protective mask head cover 1, a track arc plate 3 is fixedly connected to the inner wall of the inner support helmet 2, three sliding connecting plates 31 are slidably connected to the inner wall of the track arc plate 3, elastic sweat-absorbing cotton blocks 32 are fixedly connected to the inner wall of the sliding connecting plate 31, a guide slider 4 is slidably connected to the side wall of the track arc plate 3, the guide slider 4 is detachably connected to the sliding connecting plate 31, traction ropes 42 are fixedly connected to both sides of the guide slider 4, and a control panel 5 is installed on one side of the inner support helmet 2.

[0031] During the specific implementation process: the three elastic sweat-absorbent cotton blocks 32 are all stored in the limiting frame plate 35, and the elastic sweat-absorbent cotton blocks 32 are in a compressed state. After wearing a mask, the staff wears the inner support helmet 2 on the top of the head, and the binding belt 21 is tied to the chin of the user. Then the staff adheres the control panel 5 to the shoulder of the user near the neck. Then the staff puts the protective mask head cover 1 and the protective mask transparent plate 11 on the top of the inner support helmet 2. The protective mask transparent plate 11 corresponds to the facial position of the user, and the lower part of the protective mask head cover 1 hangs down on the chest position of the user. The staff wears surgical protective clothing and wraps the lower part of the protective mask head cover 1 in the surgical protective clothing. The staff performs the operation normally. When there is no need to wipe the sweat, the protective mask head cover 1 and the protective mask transparent plate 11 worn by the staff use the basic functions of the protective mask. The protective mask head cover 1 and the protective mask transparent plate 11 protect the head and neck of the user, and the head and neck of the user will not be contaminated by external tissue splashes and droplets. When it is necessary to wipe the sweat, the user's head is tilted at a large angle toward the shoulder position where the control panel 5 is installed, and the elastic squeezing plate 52 is squeezed by the head, and the elastic squeezing plate 52 squeezes the top of the control panel 5. The control button 51 transmits an electrical signal to the electric winding rollers 43 to control one of the electric winding rollers 43 to start, and the traction rope 42 is wound up by the winding roller on the electric winding roller 43, and the traction guide slider 4 moves along the track of the track arc plate 3, and the guide slider 4 drives the sliding connection plate 31 and the elastic sweat-absorbing cotton block 32 to move synchronously. After the elastic sweat-absorbing cotton block 32 is separated from the limit frame plate 35, it is unfolded under the action of its own elastic force, and contacts along the forehead skin of the user. During the movement of the elastic sweat-absorbing cotton block 32, the sweat on the forehead of the user is wiped until the elastic sweat-absorbing cotton block 32 The guide slider 4 and the flip pull plate 41 are pressed by the sliding connection plate 31 to rotate and are pulled out from the clearance slot 33, so that the flip pull plate 41 is out of contact with the sliding connection plate 31. As the guide slider 4 and the flip pull plate 41 move further, until the flip pull plate 41 moves to the unused sliding connection plate 31, the flip pull plate 41 is pressed and flipped, and passes through the clearance slot 33 to be used next time. The three elastic sweat-absorbent cotton blocks 32 can provide three sweat-wiping operations for the user to prevent sweat from dripping into the user's eyes, so that the staff can stably complete the surgical operation. After the operation is completed, the staff removes the device from the head, and then removes the elastic sweat-absorbent cotton block 32 from the sliding connecting plate 31, cleans and disinfects the device, and glues a new elastic sweat-absorbent cotton block 32 to the sliding connecting plate 31, and then adjusts the sliding connecting plate 31 and the elastic sweat-absorbent cotton block 32 to reset through the controller, and packages the device for next use.

[0032] The bottom end of the inner support helmet 2 is fixedly connected with a binding and tightening belt 21 which plays a fixing role; by providing the binding and tightening belt 21, the inner support helmet 2 can be firmly worn on the head of the person to prevent the binding and tightening belt 21 from swinging or falling.

[0033] A yielding slot 33 is provided on the sliding connection plate 31, and a flip pulling plate 41 which plays a limiting role is hinged at the end of the guide slider 4; the flip pulling plate 41 is connected to the guide slider 4 through a torsion spring shaft. When the flip pulling plate 41 moves in the reverse direction, the flip pulling plate 41 will be squeezed and flipped by the sliding connection plate 31, and the distance between the two ends of the flip pulling plates 41 is reduced so that the flip pulling plate 41 can pass through the yielding slot 33. When the flip pulling plate 41 moves forward, the flip pulling plate 41 opens under the elastic force of the torsion spring shaft itself, and is limited by the flip limiting plate 44 to prevent over-flipping. The expansion range of the flip pulling plate 41 is larger than the opening range of the yielding slot 33. The flip pulling plate 41 conflicts with the sliding connection plate 31, which can drive the sliding connection plate 31 to move, and then drive the elastic sweat-absorbing cotton block 32 to move together.

[0034] A guide slot 34 is provided on the track arc plate 3, and the guide slider 4 is slidably connected to the inner wall of the guide slot 34; the guide slot 34 can play a role of giving way and guiding, and the guide slider 4 can pass through the track arc plate 3 and be connected to the traction rope 42.

[0035] Both ends of the track arc plate 3 are fixedly connected to the limit frame plate 35, the elastic sweat-absorbent cotton block 32 is accommodated in the limit frame plate 35, and the side wall of the limit frame plate 35 is fixedly connected with the protective cotton pad 36; by setting the limit frame plate 35, the elastic sweat-absorbent cotton block 32 can be isolated and protected, so as to prevent the elastic sweat-absorbent cotton block 32 from absorbing sweat on the side of the person's head when not in use, and to prevent the sweat absorption capacity of the elastic sweat-absorbent cotton block 32 from decreasing; by setting the protective cotton pad 36, the limit frame plate 35 can be prevented from directly contacting the person's head, thereby improving the comfort of the person wearing it, and at the same time, the protective cotton pad 36 can be used to absorb the sweat on the side of the person's head.

[0036] The ends of the two traction ropes 42 are both equipped with electric winding rollers 43, and the end of the guide slider 4 is fixedly connected to a flip limit plate 44; by setting the flip limit plate 44, the flipping of the flip pulling plate 41 can be limited to avoid excessive flipping of the flip pulling plate 41 and failure to effectively apply force to the sliding connecting plate 31.

[0037] A control button 51 is installed on the top of the control panel 5, and an elastic squeezing plate 52 is hinged on the top of the control panel 5. The elastic squeezing plate 52 covers the top of the control button 51. A connecting line 53 is fixedly connected to one side of the control panel 5, and the control panel 5 is electrically connected to the electric winding roller 43 through the connecting line 53; an adhesive sticker is provided on the bottom end surface of the control panel 5 so that the control panel 5 can be bonded and fixed on the person's clothing. The elastic squeezing plate 52 can increase the force-bearing area, so that when the person's head is tilted, the elastic squeezing plate 52 will be squeezed first, and the control button 51 can be effectively squeezed with the help of the elastic squeezing plate 52, so as to avoid deformation of the skin of the person after direct contact with the control button 51, thereby avoiding the failure to apply sufficient force to the control button 51.
