Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a surgical care skin preparation device. Background Art

[0002] In clinical practice, skin preparation (i.e., preoperative skin preparation) is a crucial step before surgery. Because a large number of microorganisms, such as bacteria and fungi, exist on the skin surface, especially in hair-dense areas such as the perineum, axillae, and scalp, skin preparation significantly reduces the number of bacteria around the surgical incision by removing hair and cleaning the skin, reducing the chance of pathogens invading the body through the incision, thereby lowering the risk of postoperative infection and optimizing surgical conditions.

[0003] During surgery, although residual hair may interfere with the surgical field of view or the disinfection effect, the incision position can be adjusted according to surgical needs to avoid hair-dense areas. As long as the hair does not block the surgical field of view and does not interfere with instrument operation, such as electric knife and ultrasonic knife, there is no need to use electric razors, scissors and other methods to cut hair inefficiently. Only the surgical part needs to be cleaned and disinfected. For example, in laparoscopic surgery, umbilical hair can be avoided by adjusting the Trocar puncture point, and no skin preparation is required; modified radical mastectomy for breast cancer can design an arc-shaped incision to avoid axillary hair.

[0004] In the process of disinfection and skin preparation, if the skin preparation time is too early (such as more than 24 hours before the operation), the skin may be re-processed by bacteria due to regeneration or contact with pollutants. In addition, the skin preparation does not cover all potential contaminated areas (such as puncture points and drainage tube outlets), which may cause the spread of infection during or after the operation. At the same time, in the process of skin preparation for the patient's private parts, the patient is usually required to handle it by himself, which may lead to incomplete skin preparation and require nurses or doctors to handle it again, such as the anus preparation required for Miles surgery. Therefore, the present invention provides a surgical nursing skin preparation device that uses a hydrogel substance to carry a disinfectant to clean, disinfect and isolate the local skin to meet the skin preparation requirements. Summary of the Invention

[0005] To solve the above problems, the present invention provides a surgical care skin preparation device, which uses hydrogel substances to carry disinfectant to clean, disinfect and isolate local skin, ensuring the convenience of the skin preparation process and the uniformity of applying the hydrogel, and meeting the skin preparation requirements.

The partition is fixedly connected to the storage tube, the first chamber is located above the partition, and the second chamber is located below the partition. The first chamber is used to store the disinfectant, and the second chamber is used to store the hydrogel solution.

[0013] The infusion mechanism includes a spray tube and a piston. A compression chamber is formed in the storage tube. The piston slides with the storage tube and is located in the compression chamber. One end of the spray tube is connected to the compression chamber. The end of the spray tube away from the compression chamber passes through the main rod, the support rod and the sleeve in sequence. The end of the spray tube away from the compression chamber is located between the baffle and the smear ball.

[0014] A plurality of transfer tubes are connected between the first and second chambers and the compression chamber.

A blocking block is slidably fitted in the transfer tube. A first spring is fixedly connected to the side of the blocking block away from the compression chamber. An electromagnet is fixedly connected to the side of the piston close to the first and second chambers. A magnet with opposite magnetic properties to the electromagnet is fixedly connected to the blocking block. The electromagnet is electrically connected to a button located at the end of the piston away from the storage tube.

[0015] When the electromagnet is activated, the magnet on the blocking block opens the transfer tube due to the repulsive magnetic force, and the first spring is in a compressed state; when the electromagnet is not activated, the blocking block is pushed by the reset first spring to close the transfer tube.

[0016] Furthermore, a glass layer is fixedly connected to the outer wall of the storage tube, and scale lines are engraved on the glass layer, and the scale lines correspond to the first chamber and the second chamber.

[0017] Furthermore, a dosing tube for adding medicine is opened at the center of the piston, a one-way valve is connected in the dosing tube, and an auxiliary push rod is slidably fitted in the dosing tube.

[0018] Furthermore, one end of the piston away from the storage tube is fixedly connected to a push handle, and the button is located on the push handle.

[0020] Furthermore, one end of the spray pipe away from the main rod is located on the side of the baffle close to the coating ball, and the spray pipe is connected to a first solenoid valve and a second solenoid valve respectively, and the first solenoid valve and the second solenoid valve are symmetrically arranged with the baffle as the center;

[0021] A first pressure sensor and a second pressure sensor are fixedly connected to both sides of the smear ball, the first solenoid valve corresponds to the position of the first pressure sensor, and the second solenoid valve corresponds to the position of the second pressure sensor; the first pressure sensor and the second pressure sensor are both used to detect pressure data when the smear ball contacts the external skin, the pressure data detected by the first pressure sensor is the first pressure data, and the pressure data detected by the second pressure sensor is the second pressure data, and the first pressure sensor and the second pressure sensor are both electrically connected to the control panel;

[0022] The control panel is used to calculate the difference between the first pressure data and the second pressure data, and compare the difference with the set rated value. If the difference is less than the rated value, a start instruction is sent to the first solenoid valve and the second solenoid valve; if the difference is greater than the rated value, the first pressure data and the second pressure data are compared. If the first pressure data is greater than the second pressure data, a start instruction is sent to the first solenoid valve corresponding to the first pressure data; if the first pressure is less than the second pressure data, a start instruction is sent to the second solenoid valve corresponding to the second pressure data.

[0023] Furthermore, the control panel is also used to record the rotation direction of the smear ball, using one of the smear balls as a reference ball, and using the control sequence corresponding to the first solenoid valve and the second solenoid valve corresponding to the current reference ball as a reference control program, and sending the reference control program to the smear ball in the next rotation direction according to the rotation time of the smear ball.

[0024] Furthermore, the first solenoid valve and the second solenoid valve on the baffle penetrate the baffle, and the spray pipe is communicated with the upper and lower sides of the baffle through the first solenoid valve and the second solenoid valve.

[0025] Furthermore, the blocking blocks corresponding to the first chamber and the second chamber are in different directions, and an indicator needle is fixedly connected to the push handle, and the indicator needle and the electromagnet are in the same direction.

[0028] 2. In this solution, during the skin preparation process, the infusion mechanism is used to change the delivery of disinfectant and hydrogel solution to achieve disinfection of the local skin. After the disinfection is completed, the hydrogel solution is applied to the local skin to continuously protect the local skin through the hydrogel solution, thereby reducing secondary contamination of the prepared skin by external bacteria and improving the skin preparation effect.

[0029] 3. In this solution, during the application of disinfectant and hydrogel solutions, a rolling application ball is used to move on the skin, so as to ensure the uniformity of the hydrogel solution after application according to the adjustment support of the support mechanism to meet the needs of skin preparation.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] The following is further described in detail through specific implementation methods:

[0042] As attached Figures 1 to 6The figure shows a surgical skin preparation device, comprising a storage tube 1 for storing disinfectant and hydrogel solution. One end of the storage tube 1 is connected to a plurality of applicator balls 45 for contacting the skin surface. The applicator balls 45 are covered with a foam layer. An annular shielding layer 11 is fixedly connected to the end of the storage tube 1 near the applicator balls 45. In this embodiment, the shielding layer 11 is a deformable rubber layer. A support mechanism is provided between the applicator balls 45 and the storage tube 1 to adjust the support height of the applicator balls 45 in various directions.

[0043] The support mechanism includes a branch-shaped bracket, which includes a main rod 41 and a plurality of support rods 42. A bearing 4 is provided between the main rod 41 and the storage tube 1. The bearing 4 is fixedly connected to the storage tube 1. The tops of the support rods 42 are all fixedly connected to the main rod 41. A sleeve 43 is slidably fitted within the support rod 42. The end of the sleeve 43 away from the support rod 42 is rotatably fitted with an smear ball 45. A second spring 46 is provided between the smear ball 45 and the support rod 42. The second spring 46 is sleeved on the sleeve 43. One end of the second spring 46 is fixedly connected to the support rod 42, and the other end of the second spring 46 is fixedly connected to the end of the sleeve 43 near the smear ball 45. In other embodiments, the end of the main rod 41 near the storage tube 1 is fixedly connected to the fan blade 30, and the fan blade 30 is located within the storage tube 1.

[0044] In another embodiment, a baffle 44 is hingedly connected to the end of the sleeve 43 away from the support rod 42. An applicator ball 45 is located within the baffle 44. Both ends of the applicator ball 45 are fixedly connected to a rotating shaft, which rotates in conjunction with the baffle 44. The baffle 44 adjusts the direction of rotation of the applicator ball 45 as the sleeve 43 rotates, while also providing support space for the deformation of the second spring 46. The rotating shaft slides within the baffle 44, allowing the applicator ball 45 to roll and apply the solution to the skin, facilitating even application of the disinfectant or hydrogel solution delivered by the infusion mechanism.

[0045] An infusion mechanism for delivering disinfectant or hydrogel solution is connected between the smear ball 45 and the storage tube 1. A cavity is formed in the storage tube 1, and a partition 13 is provided in the cavity for dividing the cavity into a first chamber 12 and a second chamber 14. The partition 13 is fixedly connected to the storage tube 1, with the first chamber 12 located above the partition 13 and the second chamber 14 located below the partition 13. The first chamber 12 is used to store disinfectant, and the second chamber 14 is used to store hydrogel solution. A glass layer (not shown) is fixedly connected to the outer wall of the storage tube 1, and the glass layer is engraved with scale lines corresponding to the first chamber 12 and the second chamber 14. The scale lines display the amount of liquid inside the first chamber 12 and the second chamber 14, making it easy to add and replenish according to the amount of liquid, thereby improving convenience during use.

[0046] The infusion mechanism includes a spray tube 3 and a piston 2. A compression chamber is opened in the storage tube 1. The piston 2 slides with the storage tube 1 and is located in the compression chamber. One end of the spray tube 3 is connected to the compression chamber, and the end of the spray tube 3 away from the compression chamber passes through the main rod 41, the support rod 42 and the sleeve 43 in sequence, and the end of the spray tube 3 away from the compression chamber is located between the baffle 44 and the smear ball 45. There are several transfer tubes connected between the first chamber 12 and the second chamber 14 and the compression chamber. The diameter of the transfer tube close to the compression chamber is smaller than the diameter of the transfer tube away from the compression chamber. A blocking block 25 is slidably fitted in the transfer tube, and the side of the blocking block 25 away from the compression chamber is fixedly connected to the first Spring 26, one end of the first spring 26 is fixedly connected to the blocking block 25, and the other end of the first spring 26 is fixedly connected to the storage tube 1. The side of the piston 2 close to the first chamber 12 and the second chamber 14 is fixedly connected to the electromagnet 24, and a magnet block with opposite magnetic properties to the electromagnet 24 is fixedly connected to the blocking block 25. The electromagnet 24 is electrically connected to the button 22, and the button 22 is located at the end of the piston 2 away from the storage tube 1; when the electromagnet 24 is started, the magnet block on the blocking block 25 opens the transfer tube due to the repulsive magnetic force, and the first spring 26 is in a compressed state; when the electromagnet 24 is not started, the blocking block 25 is pushed by the reset first spring 26 to close the transfer tube.

[0047] The specific implementation process is as follows:

[0048] First, the disinfectant and the hydrogel solution are added to the first chamber 12 and the second chamber 14. Depending on the location where the skin needs to be prepared, the skin is shielded by the shielding layer 11 to form a relatively closed space, that is, to reduce the contact between bacteria and dust in the outside air and the disinfected skin surface, thereby ensuring the disinfection effect; the shielding layer 11 also facilitates the disinfectant or hydrogel to continue to contact the skin preparation location, thereby ensuring the disinfection and isolation effects.

[0049] The piston 2 pushes the storage tube 1 to pressurize and transport the liquid to the internal chamber of the spray tube 3. The flow of liquid drives the fan blades 30 to rotate, which in turn drives the main rod 41 to rotate, so as to push the smear ball 45 to roll on the skin surface. The bearing 4 is used to reduce the friction between the main rod 41 and the storage tube 1, so that the main rod 41 can rotate. The support rod 42 drives the smear ball 45 to rotate on the skin to achieve the application of the disinfectant or hydrogel solution. During the contact between the smear ball 45 and the skin, the supporting elastic force of the second spring 46 is used to ensure that the smear ball 45 contacts the skin at different heights, so as to ensure the uniformity of the application of the disinfectant or hydrogel solution during the contact between the smear ball 45 and the skin through the foam layer. By changing the support between the smear ball 45 and the external skin in different directions, the application needs of skin of different shapes can be adapted, thereby improving the application range of the device and the needs of skin preparation, and improving the disinfection and cleaning effects of the local skin during the skin preparation process.

[0050] Since the first chamber 12 and the second chamber 14 store the disinfectant solution and the hydrogel solution separately, the disinfectant solution and the hydrogel solution can be compressed sequentially during the downward pressure of the piston 2. During the switching spraying of the disinfectant solution and the hydrogel solution, the button 22 is used to control the electromagnet 24 so that the patient can repeatedly spray the disinfectant or the hydrogel solution according to the needs of use. At the same time, the button 22 can be continuously pressed to control the activation of the electromagnet 24, and the blocking block 25 is controlled to be pushed in sequence according to the height sequence of the disinfectant solution and the hydrogel solution, so as to open the first chamber 12 and the second chamber 14 in sequence to push the disinfectant solution and the hydrogel solution in sequence.

[0051] After disinfection is completed, the local skin is treated with a hydrogel solution. After solidification, the hydrogel solution will form a fixed adsorption to continuously protect the local skin through the hydrogel solution, thereby reducing the secondary contamination of the external bacteria and the prepared skin and improving the skin preparation effect.

[0052] In another embodiment, a dosing tube 23 for adding medicine is opened at the center of the piston 2 , a one-way valve is connected to the dosing tube 23 , and an auxiliary push rod is slidably fitted in the dosing tube 23 .

[0053] The specific implementation process is as follows: the inside of the dosing tube 23 is pressurized by the booster rod to achieve the delivery of the drug solution to the inside of the storage tube 1, which facilitates the mixing of the drug solution and the hydrogel solution. When the hydrogel solution is applied to the skin, the drug solution inside the hydrogel solution is used to sterilize the skin, thereby ensuring the skin preparation effect.

[0054] After the hydrogel solution is applied, the polyelectrolyte solution is delivered via the dosing tube 23 , and polyelectrolyte layers are alternately deposited on the surface of the hydrophilic hydrogel through electrostatic interaction to form a nanoscale composite film, thereby enhancing the interfacial bonding force.

[0055] In another embodiment, a push handle 21 is fixedly connected to the end of the piston 2 away from the storage tube 1, and a button 22 is located on the push handle 21. The push handle 21 facilitates the movement of the piston 2, making it easier for medical staff and patients to use it, facilitating the suction and compression of liquids in the first chamber 12 and the second chamber 14, and facilitating disinfection and application.

[0056] The blocking blocks 25 corresponding to the first chamber 12 and the second chamber 14 are located in different directions, and an indicator needle is fixedly connected to the push handle 21 , and the indicator needle and the electromagnet 24 are located in the same direction.

[0057] The specific implementation process is as follows: the blocking blocks 25 corresponding to the first chamber 12 and the second chamber 14 are arranged in different directions to reduce the possibility of the electromagnet 24 being accidentally activated by continuously pressing the button 22 when the disinfectant or hydrogel solution is sprayed. Medical staff and patients can control the opening of the first chamber 12 and the second chamber 14 as needed, and accurately control the disinfectant and hydrogel solution by using the accurate indication of the indicator needle.

[0058] In another embodiment, one end of the spray pipe 3 away from the main rod 41 is located on the side of the baffle 44 close to the smear ball 45, and the spray pipe 3 is respectively connected with a first solenoid valve 31 and a second solenoid valve 32, and the first solenoid valve 31 and the second solenoid valve 32 are symmetrically arranged with the baffle 44 as the center; a first pressure sensor 5 and a second pressure sensor 51 are fixedly connected on both sides of the smear ball 45, the first solenoid valve 31 corresponds to the position of the first pressure sensor, and the second solenoid valve 32 corresponds to the position of the second pressure sensor 51; the first pressure sensor 5 and the second pressure sensor 51 are both used to detect the pressure data when the smear ball 45 contacts the external skin, the pressure data detected by the first pressure sensor 5 is the first pressure data, and the second pressure sensor 51 is used to detect the pressure data when the smear ball 45 contacts the external skin. The pressure data detected by the second pressure sensor 51 is the second pressure data. The first pressure sensor 5 and the second pressure sensor 51 are both electrically connected to the control panel. The control panel is used to calculate the difference between the first pressure data and the second pressure data, and compare the difference with the set rated value. If the difference is less than the rated value, a start instruction is sent to the first solenoid valve 31 and the second solenoid valve 32. If the difference is greater than the rated value, the first pressure data and the second pressure data are compared. If the first pressure data is greater than the second pressure data, a start instruction is sent to the first solenoid valve 31 corresponding to the first pressure data. If the first pressure is less than the second pressure data, a start instruction is sent to the second solenoid valve 32 corresponding to the second pressure data.

[0059] For example, during the operation of the application ball 45, due to the different changes in the curvature of the skin surface, the first pressure sensor 5 and the second pressure sensor on the application ball 45 receive different pressure data. Based on the comparison of the first pressure data and the second pressure data, the spray tube 3 sprays more liquid to apply to more skin surfaces of the protrusions, which is convenient for disinfecting the hidden grooves between the protrusions, thereby ensuring the skin preparation effect.

[0060] The control panel is also used to record the rotation direction of the smear ball 45, taking one of the smear balls 45 as a reference ball, and based on the control sequence corresponding to the first solenoid valve 31 and the second solenoid valve 32 corresponding to the current reference ball as a reference control program, the reference control program is sent to the smear ball 45 in the next rotation direction according to the rotation time of the smear ball 45.

[0061] For example, since the smear ball 45 rotates continuously, the contact between the smear ball 45 and the skin changes continuously during different rotation processes of the smear ball 45. Therefore, the smear ball 45 in the rotation direction is controlled in advance to ensure the continuity of the smear ball 45 in the liquid application process, thereby ensuring the continuity of the application of the disinfectant and hydrogel solution.

[0062] In other embodiments, the first solenoid valve 31 and the second solenoid valve 32 on the baffle 44 pass through the baffle 44 , and the spray pipe 3 is connected to the upper and lower sides of the baffle 44 through the first solenoid valve 31 and the second solenoid valve 32 .

[0063] The specific implementation process is as follows: the first solenoid valve 31 and the second solenoid valve 32 are connected to the upper and lower sides of the baffle 44 to increase the area of ​​the liquid sprayed by the spray pipe 3, thereby facilitating the disinfection of the skin within the shielding layer 11, reducing the bacterial content of the subsequent hydrogel solution solidified on the skin surface, and ensuring the skin preparation effect.

[0064] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
