Description

Technical Field

[0001] The invention belongs to the technical field of medical devices. Background Art

[0002] Venipuncture is a procedure that uses a specific puncture instrument (such as a syringe needle, intravenous catheter, etc.) to puncture a vein through the skin in order to collect blood, infuse fluids, drugs, or perform other treatments or examinations.

[0003] During venipuncture, medical staff have great difficulty in venipuncturing obese patients, children, the elderly, or other people with low vascular perfusion due to low vascular visibility. For example, infants and young children have thin veins and less subcutaneous fat, which makes them easy to slide; elderly patients have thin veins that are easy to roll, are brittle, and easily bleed; obese patients have veins that are deeply buried under the fat layer, and palpation and visual positioning are ineffective. Currently, when performing venipuncture on people with low vascular perfusion, nurses need to rely on experience and feel to judge the location and direction of the blood vessels, and at the same time, the requirements for puncture technology are higher, and the failure rate is high.

[0004] In the prior art, a Chinese patent with application number 202120042828.9 proposes a skin softening device before venous puncture for scleroderma, including a handle, a thermostat, a lithium battery, a driving mechanism, a resetting mechanism, a linkage mechanism, a placement groove, a heating wire, a copper plate, and a ball. The thermostat is fixedly provided on the top of the handle, and a lithium battery is tightly provided on the top of the handle. A driving mechanism is fixedly provided on the upper end of the handle. A resetting mechanism is rotatably penetrated through the bottom of the handle. A linkage mechanism is fixedly provided on the outer wall of the resetting mechanism. A placement groove is integrally provided on the left and right sides of the bottom end of the handle. A heating wire is fixedly provided inside the placement groove. A copper plate is fixedly provided at the bottom of the resetting mechanism. Balls are rotatably provided inside the copper plate. There are several balls.

[0005] In the above-mentioned prior art, the puncture site of the patient is softened by performing a hot compress operation. However, when performing the hot compress, it is impossible to judge whether the patient's vascular filling degree meets the puncture requirements after the hot compress, and the auxiliary means are single. Once the hot compress effect is not good, there are no other supplementary measures to help improve the puncture effect for special populations. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a venous puncture pre-treatment device. The venous puncture pre-treatment device includes an identification structure, a hot compress structure, and a filling degree judgment structure, which can judge whether the blood vessel filling degree of the puncture site meets the puncture requirements after the patient performs hot compress.

[0007] The present invention provides the following technical solutions: A venipuncture pre-treatment device, comprising an identification structure, a hot compress structure, and a filling degree determination structure; The identification structure includes a puncture area feature library and an identification and comparison module; the identification and comparison module can collect the patient's puncture area feature information and compare it with the puncture area feature library to determine whether the patient needs a hot compress before puncture; The hot compress structure can perform a hot compress operation on the puncture site; The filling degree determination structure includes a vascular information acquisition module, a filling degree target prediction module and a filling degree assessment module; the vascular information acquisition module can collect vascular data information of the patient's puncture site; the filling degree target prediction module is preset with a standard vascular filling degree feature library; the filling degree assessment module can receive the vascular data information of the patient's puncture site collected by the vascular information acquisition module, and compare it with the standard vascular filling degree feature library to determine whether the patient's vascular filling degree meets the puncture standard.

[0008] Furthermore, the feature information configured in the puncture area feature library is the blood vessel visibility image feature and / or blood vessel inner diameter information feature of the puncture area.

[0009] Furthermore, the characteristic information configured in the standard vascular filling characteristic library is the blood vessel inner diameter information and / or the image information of the blood vessel visibility on the skin.

[0010] Furthermore, the hot compress structure applies hot compress to the puncture site by spraying warm steam, spraying hot air or outputting hot and humid fiber material.

[0011] Furthermore, the venipuncture pre-treatment device is provided with a box body, and a tubular lumen-shaped hot compress structure is provided on the box body, which can be used to accommodate the patient's puncture area and perform hot compress on the puncture area.

[0012] Furthermore, the intravenous puncture pre-treatment device includes an upper box body and a lower box body, and the upper box body and the lower box body are connected by a rotating shaft; the hot compress structure includes an upper arc-shaped cavity and a lower arc-shaped cavity, and the upper arc-shaped cavity and the lower arc-shaped cavity are respectively arranged on the opposite sides of the upper box body and the lower box body, and the hot compress structure can be opened and closed by rotating the rotating shaft.

[0013] Furthermore, the venipuncture pre-treatment device is also provided with a rolling structure, and the rolling structure is provided with an arm ring.

[0014] Furthermore, the rolling structure is also provided with a columnar positioning module, which passes through the arm ring and is connected to the ball bearing. The columnar positioning module can adjust the pressure applied to the connected ball bearing to adapt to the irregular shape of the arm.

[0015] Furthermore, a touch pressure detector is provided inside the ball, which can detect the pressure of the ball on the skin and upload the pressure value to the columnar adjustment module. The columnar adjustment module determines whether the pressure value of the ball is within the threshold range based on a preset pressure threshold. When the judgment is no, the pressure value of the aforementioned ball is adjusted.

[0016] The present invention also provides a method for implementing the aforementioned venipuncture pre-treatment device, the method steps comprising: Collect the characteristic information of the patient's puncture area and compare it with the characteristic information in the puncture area characteristic library to determine whether the patient needs a hot compress before puncture; If the answer is yes, apply hot compress to the puncture area of ​​the patient; After the hot compress operation is completed, the vascular filling degree of the patient's puncture area is judged. When the patient's vascular filling degree does not reach the preset puncture standard, the hot compress operation is performed again.

[0028] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. Example

[0029] See also Figure 1 , which is a venipuncture pre-treatment device 100 provided by the present invention.

[0030] In this embodiment, the venipuncture pre-treatment device 100 includes an identification structure 110 , a hot compress structure 120 , and a filling degree determination structure 130 .

[0031] The identification structure 110 includes a puncture area feature library 111 and an identification and comparison module 112; the identification and comparison module 112 can collect the patient's puncture area feature information and compare it with the puncture area feature library 111 to determine whether the patient needs hot compress treatment before puncture.

[0032] In a specific implementation, the feature information corresponding to the puncture area feature library 111 may be a blood vessel visibility image feature or a blood vessel inner diameter information feature of the puncture area.

[0033] The hot compress structure 120 can perform a hot compress operation on the puncture site. As a non-invasive auxiliary treatment method, hot compress promotes vasodilation, increases blood flow, and improves local blood circulation through temperature stimulation; humidity helps to maintain the appropriate moisture of the skin, reduce dryness or discomfort, thereby improving the patient's comfort and may have a positive effect on vascular filling.

[0034] In a specific implementation, the heat compress structure 120 can apply heat to the puncture site by spraying hot air or warm steam; or by outputting hot and humid fiber materials, such as a hot towel, to apply heat to the puncture site.

[0035] Preferably, the hot compress structure 120 is provided with a hot compress head, and the hot compress head is provided with a hole array for spraying warm steam or hot air to apply hot compress to the puncture site.

[0036] In specific implementation, as an example but not a limitation, in order to make the patient feel more comfortable, the layer of the heating head that contacts the human body can be made of a soft elastic material, such as a high temperature resistant silicone material.

[0037] In a specific implementation, the hot compress structure 120 is provided with a default mode. Preferably, the default mode sets the hot compress temperature between 40°C and 45°C; the hot compress time is set to 15-30 minutes; and / or the hot compress humidity can be set to a specific steam jet frequency.

[0038] In a specific implementation, the hot compress structure 120 may also be provided with a temperature and humidity sensor for monitoring the temperature and humidity information of the hot compress area.

[0039] In specific implementation, the hot compress structure 120 may also be provided with a hot compress adjustment module, which can adjust the temperature, humidity and / or time of the hot compress. Since different patients may react differently to hot compress, the temperature, humidity and / or time need to be adjusted according to the patient's constitution, local skin condition, etc.

[0040] In a specific implementation, the hot compress adjustment module is also provided with a patient reaction collection subunit, which can collect the patient's reaction information during the hot compress process, including but not limited to the patient's expression, sound, voice, skin condition and other information. According to the collected reaction information, the hot compress adjustment module controls the hot compress structure to adjust the temperature, humidity and / or time of the hot compress operation. For example, when the hot compress adjustment module collects the patient's shouting "hot", the hot compress temperature and humidity are adjusted; when the patient's skin turns red quickly after the hot compress, the hot compress time can be adjusted.

[0041] The patient's facial expression, sound, voice, skin condition and other information can be collected through image, sound and other collection equipment. The relevant scheme belongs to the existing technology and will not be elaborated here.

[0042] The filling degree determination structure 130 includes a vascular information acquisition module 131, a filling degree target prediction module 132 and a filling degree assessment module 133; the vascular information acquisition module 131 can collect vascular data information of the patient's puncture site; the filling degree target prediction module 132 is preset with a standard vascular filling degree feature library; the filling degree assessment module 133 can receive the vascular data information of the patient's puncture site collected by the vascular information acquisition module 131, and compare it with the standard vascular filling degree feature library to determine whether the patient's vascular filling degree meets the puncture standard.

[0043] In specific implementation, the hot compress adjustment module can adjust the temperature, humidity and / or time of the hot compress operation according to the result of the patient's vascular filling degree determined by the filling degree assessment module. For example, when it is monitored that the patient's vascular filling degree is low, the hot compress adjustment module can increase the temperature of the hot compress by controlling the hot compress structure, increase the spray frequency of water vapor, or appropriately extend the hot compress time, etc., to improve the effect of the hot compress.

[0044] like Figure 2 As shown, in this embodiment, the intravenous puncture pre-treatment device 100 is provided with a box body, and a tubular lumen-shaped hot compress structure 120 is provided on the box body, which can be used to accommodate the patient's puncture area and apply hot compress to the puncture area.

[0045] In specific implementation, the hot compress structure 120 is set to an openable and closable structure. Since some patients may have indwelling tubes and other devices left in the puncture area, directly extending into the tubular heat compress structure may easily touch the indwelling tubes and other devices. By setting the hot compress structure to an openable and closable structure, when the patient needs to apply hot compress, the tubular heat compress structure is opened, the area of ​​the arm that needs to be applied hot compress is directly placed in the hot compress lumen, and then the tubular heat compress structure is covered, so that it is not easy to touch the indwelling tubes and other devices left in the puncture area.

[0046] Preferably, Figure 3 As shown, the venipuncture pretreatment device 100 includes an upper box 140 and a lower box 150, and the upper box and the lower box are connected by a rotating shaft. The hot compress structure 120 includes an upper arc cavity 121 and a lower arc cavity 122, and the upper arc cavity and the lower arc cavity are respectively arranged on opposite sides of the upper box 140 and the lower box 150. The hot compress structure 120 can be opened and closed by rotating the rotating shaft.

[0047] like Figure 4 As shown, in this embodiment, in order to make the patient's blood vessels more filled, the venipuncture pre-treatment device 100 is further provided with a rolling structure 160.

[0048] In specific implementation, the rolling structure 160 is provided with an arm ring 161, which can be wrapped around the patient's arm. A plurality of balls 162 are provided inside the arm ring 161, and a first drive motor and a second drive motor are provided corresponding to the balls. The first drive motor (such as a linear motion motor) can be provided inside the ball or inside the arm ring, and the ball 162 can move away from or close to the inside of the arm ring based on the first motor drive to achieve the pressing and relaxing of the skin by the ball; the second drive motor (such as a rotary motor) is provided inside the ball or the output end of the rotary motor corresponds to the ball setting, and the rotary motor drives the ball to rotate relative to the inside of the arm ring to achieve rolling. The control circuits of the first drive motor and the second drive motor are connected to the fullness determination structure 130 in communication, and can receive the control instructions of the fullness determination structure 130. After receiving the control instructions of the fullness determination structure 130, the corresponding operation is performed after judging the type of the instructions. The control instructions include the first control instruction, the second control instruction and the third control instruction. The first control instruction is a pressing instruction, which blocks the blood reflux of blood vessels by pressing, thereby improving the blood vessel filling degree; the second control instruction is a rolling instruction, which can effectively improve the problem of poor local blood circulation by rolling, and avoid the low blood vessel filling degree caused by venous blood stagnation; the third control instruction is a rolling and pressing instruction, which rolls along the patient's limb toward the puncture site by rolling and pressing, so that blood gathers at the puncture site and the blood vessel is filled more.

[0049] The rolling is preferably bidirectional rolling, by respectively arranging a forward rotating motor and a reverse rotating motor on opposite sides of the ball, and the output ends of the two rotating motors are arranged corresponding to the ball. The forward rotating motor drives the ball to roll from top to bottom along the arm, and the reverse rotating motor drives the ball to roll from bottom to top along the arm.

[0050] Preferably, a rolling direction control unit is also provided in the ball 162, and the rolling direction control unit is preset with a rolling boundary feature library, and identifies through a sensor (such as an image sensor) whether the ball 162 has rolled to the boundary position. When it is judged to be yes, the rolling direction control unit controls the reverse rotating motor to drive the ball to roll back in the opposite direction.

[0051] In a specific implementation, the balls 162 on the armband 161 are arranged as a uniformly distributed ball array, or are arranged as different ball arrays according to the characteristics of the muscle parts fitted in different areas of the armband 161, including but not limited to rectangular arrays, circular arrays, cross arrays and other irregular arrays.

[0052] In a specific implementation, the arm ring 161 can be formed by connecting a plurality of arc bands to form a ring band, and the material connecting the plurality of arc bands is preferably an elastic material.

[0053] Preferably, Figure 5 As shown, due to the irregular shape of human arm muscles, the arm ring 161 is provided with a columnar positioning module 163, which passes through the arm ring 161 and is connected to the ball 162. The first drive motor and the second drive motor are provided corresponding to the columnar positioning module 163 to achieve the pressing and relaxing of the skin by the ball 162, and to drive the ball 162 to rotate relative to the inner side of the arm ring to achieve rolling.

[0054] Preferably, the columnar positioning module 163 is also preset with a pressure threshold, and a touch pressure detector, such as a pressure sensor, is provided in the ball 162, which can detect the pressure of the ball 162 on the skin and upload the pressure value to the columnar positioning module 163. The columnar positioning module 163 determines whether the pressure of the ball 162 is within the threshold range according to the preset pressure threshold. When the pressure of the ball 162 is not within the threshold range, the pressure output by the first drive motor and / or the second drive motor to the ball is controlled to be within the threshold range.

[0055] Preferably, the columnar positioning module 163 is provided with a frequency selection unit, which can provide different frequency modes, such as "slow", "medium" or "fast", for the user to choose. The frequency selection unit is electrically connected to the first drive motor and the second drive motor, and can issue instructions to the first drive motor and / or the second drive motor. When the frequency selection unit receives the user's selection instruction, it forwards the instruction to the first drive motor and / or the second drive motor, and the first drive motor and / or the second drive motor adjust the operating frequency according to the type of instruction, thereby adjusting the frequency of the ball pressing and / or rolling on the skin.

[0056] In this embodiment, the venipuncture pre-treatment device 100 may also be provided with a puncture support structure, which is used to place the limb part of the patient that needs to be punctured, such as the arm, lower limb, etc.

[0057] In specific implementation, the shape of the puncture support structure is not limited, and the size can be placed on the arm or lower limb of an adult. Preferably, the puncture support structure is a rectangular flat plate structure.

[0058] In a specific implementation, the puncture support structure is provided with a puncture site alignment area. Preferably, the puncture site alignment area can be marked by lines, colors, words, etc.

[0059] In specific implementation, the puncture support structure is provided with a limiting module for limiting the puncture site of the patient to prevent the patient from moving the puncture site at will. As an example but not limitation, the limiting module can be a slot structure, an adjustable rope structure (such as a bandage, a strap, etc.), a buckle structure, etc.

[0060] Preferably, the limiting module can be simultaneously configured as a compression cuff, such as a bandage, a retractable buckle or a mechanical arm structure.

[0061] In a specific implementation, the puncture support structure is provided with an adjustment module for adjusting the position of the puncture site of the patient. As an example but not a limitation, the adjustment module can be composed of a guide rail slider, a linear bearing, etc.

[0062] In a specific implementation, the identification structure can collect the patient's position data information and identify whether the patient's puncture site is placed in a specified area on the puncture support structure.

[0063] The specified area can be set according to the specific structure of the venipuncture pre-treatment device. In specific implementation, as an example but not limitation, the specified area can be a preset puncture site alignment area, an area aligned with an identification structure, or an area aligned with a hot compress structure.

[0064] In specific implementation, the recognition structure can collect image data of the patient to perform position feature comparison to identify whether the puncture site of the patient is placed in the specified area on the puncture support structure. The specific feature comparison method is prior art and will not be described in detail here.

[0065] In specific implementation, as an example but not a limitation, when the recognition structure determines that the patient's puncture site is not placed in the specified area on the puncture support structure, it can remind the patient to move the puncture site by outputting voice or images, or control the adjustment module to adjust the patient's puncture site to the specified area.

[0066] During specific implementation, in order to make the patient's blood vessels more filled, the venipuncture pre-treatment device 100 is also provided with a cuff structure.

[0067] The cuff structure includes a cuff and a cuff adjustment module, and the cuff adjustment module can adjust the tightness of the cuff.

[0068] Preferably, the compression cuff is made of a soft, elastic medical material, such as silicone, chloroprene rubber or thermoplastic elastomer, which can provide sufficient compression force without causing excessive compression or irritation to the skin.

[0069] Preferably, in order to increase comfort, the compression cuff is provided with an inner lining layer, and the inner lining layer is made of soft foam material or breathable fiber material to ensure that friction and pressure on the skin are minimized.

[0070] During specific implementation, the cuff adjustment module can adjust the tightness of the cuff by means of air pressure or hydraulic pressure.

[0071] In specific implementation, the tourniquet is equipped with a pressure sensor inside, which can monitor the pressure data applied to the vein in real time and send it to the tourniquet adjustment module, which can automatically adjust the tightness of the tourniquet according to the preset pressure threshold. In this way, it can be ensured that the vein will not collapse or be damaged due to excessive pressure during puncture.

[0072] Studies have shown that applying two compression cuffs above and below the venipuncture site can effectively improve the filling of the blood vessels. The upper compression cuff helps the vein to expand more significantly, while the lower compression cuff helps local blood return and prevents blood vessel collapse. This double compression helps to strengthen the prominence of the vein and provide better puncture conditions.

[0073] In a specific implementation, the venipuncture pre-treatment device is provided with two compression cuff structures, which can apply pressure respectively at the upper and lower positions of the venipuncture site to help improve the filling degree of the blood vessels.

[0074] In a specific implementation, the intravenous puncture pre-treatment device also includes a intravenous puncture storage module for storing puncture supplies such as puncture needles, indwelling tubes, puncture bandages, sterile cotton balls, gauze, etc.

[0075] See also Figure 6 , which is a method for implementing the aforementioned venipuncture pre-treatment device provided by the present invention.

[0076] The method steps are: S100: collecting feature information of the patient's puncture area and comparing it with feature information in a puncture area feature library to determine whether the patient needs a hot compress before puncture; S200: When the judgment is yes, a hot compress operation is performed on the puncture area of ​​the patient; S300: After the hot compress operation is completed, the vascular filling degree of the patient's puncture area is determined. When the vascular filling degree of the patient does not reach the preset puncture standard, the hot compress operation is performed again.

[0077] In specific implementation, step S300 can also be configured to determine the vascular filling degree of the patient's puncture area after the hot compress operation is completed, and start the rolling operation when the patient's vascular filling degree does not reach the preset puncture standard.

[0078] During specific implementation, S400 may also be included.

[0079] The specific steps of S400 are configured as follows: after the rolling operation is started, the ball 162 in the rolling structure 160 will identify the pressure it exerts on the muscle and upload the pressure value to the columnar adjustment module 163. The columnar adjustment module 163 determines whether the pressure of the ball 162 is within the threshold range based on a preset pressure threshold. When the pressure of the ball 162 is not within the threshold range, the pressure of the ball 162 is adjusted to be within the threshold range.
